The South China Sea Arbitration
Award of 12 July 2016

I.

INTRODUCTION

1.

The Parties to this arbitration are the Republic of the Philippines (the “Philippines”) and thePeople’s Republic of China (“China”) (together, the “Parties”).

2.

This arbitration concerns disputes between the Parties regarding the legal basis of maritime
rights and entitlements in the South China Sea, the status of certain geographic features in theSouth China Sea, and the lawfulness of certain actions taken by China in the South China Sea.

3.

The South China Sea is a semi-enclosed sea in the western Pacific Ocean, spanning an area ofalmost 3.5 million square kilometres, and is depicted in Map 1 on page 9 below. The South
China Sea lies to the south of China; to the west of the Philippines; to the east of Viet Nam; andto the north of Malaysia, Brunei, Singapore, and Indonesia. The South China Sea is a crucial
shipping lane, a rich fishing ground, home to a highly biodiverse coral reef ecosystem, andbelieved to hold substantial oil and gas resources. The southern portion of the South China Sea
is also the location of the Spratly Islands, a constellation of small islands and coral reefs,
existing just above or below water, that comprise the peaks of undersea mountains rising fromthe deep ocean floor. Long known principally as a hazard to navigation and identified on
nautical charts as the “dangerous ground”, the Spratly Islands are the site of longstanding
territorial disputes among some of the littoral States of the South China Sea.

4.

The basis for this arbitration is the 1982 United Nations Convention on the Law of the Sea(the “Convention” or “UNCLOS”). 1 Both the Philippines and China are parties to theConvention, the Philippines having ratified it on 8 May 1984, and China on 7 June 1996. The
Convention was adopted as a “constitution for the oceans,” in order to “settle all issues relating
to the law of the sea,” and has been ratified by 168 parties. The Convention addresses a wide
range of issues and includes as an integral part a system for the peaceful settlement of disputes.
This system is set out in Part XV of the Convention, which provides for a variety of disputesettlement procedures, including compulsory arbitration in accordance with a procedure
contained in Annex VII to the Convention. It was pursuant to Part XV of, and Annex VII to,
the Convention that the Philippines commenced this arbitration against China on 22 January
2013.

5.

The Convention, however, does not address the sovereignty of States over land territory.
Accordingly, this Tribunal has not been asked to, and does not purport to, make any ruling as to1

United Nations Convention on the Law of the Sea, 10 December 1982, 1833 UNTS 3 (hereinafter“Convention”). Throughout this Award, references to particular Articles are to the Convention unlessstated otherwise.

1

The South China Sea Arbitration
Award of 12 July 2016

which State enjoys sovereignty over any land territory in the South China Sea, in particular withrespect to the disputes concerning sovereignty over the Spratly Islands or Scarborough Shoal.
None of the Tribunal’s decisions in this Award are dependent on a finding of sovereignty, norshould anything in this Award be understood to imply a view with respect to questions of landsovereignty.
6.

Similarly, although the Convention does contain provisions concerning the delimitation ofmaritime boundaries, China made a declaration in 2006 to exclude maritime boundary
delimitation from its acceptance of compulsory dispute settlement, something the Convention
expressly permits for maritime boundaries and certain other matters. Accordingly, the Tribunal
has not been asked to, and does not purport to, delimit any maritime boundary between theParties or involving any other State bordering on the South China Sea. To the extent thatcertain of the Philippines’ claims relate to events at particular locations in the South China Sea,
the Tribunal will address them only insofar as the two Parties’ respective rights and obligations
are not dependent on any maritime boundary or where no delimitation of a boundary would benecessary because the application of the Convention would not lead to any overlap of the two
Parties’ respective entitlements.

7.

The disputes that the Philippines has placed before the Tribunal fall broadly within four
categories. First, the Philippines has asked the Tribunal to resolve a dispute between the Parties
concerning the source of maritime rights and entitlements in the South China Sea. Specifically,
the Philippines seeks a declaration from the Tribunal that China’s rights and entitlements in theSouth China Sea must be based on the Convention and not on any claim to historic rights. In
this respect, the Philippines seeks a declaration that China’s claim to rights within the‘nine-dash line’ marked on Chinese maps are without lawful effect to the extent that theyexceed the entitlements that China would be permitted by the Convention.

8.

Second, the Philippines has asked the Tribunal to resolve a dispute between the Parties
concerning the entitlements to maritime zones that would be generated under the Convention by
Scarborough Shoal and certain maritime features in the Spratly Islands that are claimed by boththe Philippines and China.

The Convention provides that submerged banks and low-tide

elevations are incapable on their own of generating any entitlements to maritime areas and that“[r]ocks which cannot sustain human habitation or economic life of their own” do not generate
an entitlement to an exclusive economic zone of 200 nautical miles or to a continental shelf.
The Philippines seeks a declaration that all of the features claimed by China in the Spratly
Islands, as well as Scarborough Shoal, fall within one or the other of these categories and that

2

The South China Sea Arbitration
Award of 12 July 2016none of these features generates an entitlement to an exclusive economic zone or to acontinental shelf.
9.

Third, the Philippines has asked the Tribunal to resolve a series of disputes between the Parties
concerning the lawfulness of China’s actions in the South China Sea. The Philippines seeks
declarations that China has violated the Convention by:(a)interfering with the exercise of the Philippines’ rights under the Convention, including
with respect to fishing, oil exploration, navigation, and the construction of artificial
islands and installations;(b)failing to protect and preserve the marine environment by tolerating and actively
supporting Chinese fishermen in the harvesting of endangered species and the use ofharmful fishing methods that damage the fragile coral reef ecosystem in the South China
Sea; and(c)inflicting severe harm on the marine environment by constructing artificial islands andengaging in extensive land reclamation at seven reefs in the Spratly Islands.

10.

Fourth, the Philippines has asked the Tribunal to find that China has aggravated and extended
the disputes between the Parties during the course of this arbitration by restricting access to a
detachment of Philippine marines stationed at Second Thomas Shoal and by engaging in thelarge-scale construction of artificial islands and land reclamation at seven reefs in the Spratly
Islands.

11.

China has consistently rejected the Philippines’ recourse to arbitration and adhered to a positionof neither accepting nor participating in these proceedings. It has articulated this position in
public statements and in many diplomatic Notes Verbales, both to the Philippines and to thePermanent Court of Arbitration (the “PCA” or the “Registry”), which serves as the Registry inthis arbitration. China’s Foreign Ministry has also highlighted in its statements, press briefings,
and interviews that it considers non-participation in the arbitration to be its lawful right under
the Convention.

12.

The possibility of a party refraining from participating in dispute resolution proceedings is
expressly addressed by the Convention, which provides in Article 9 of its Annex VII that the“[a]bsence of a party or failure of a party to defend its case shall not constitute a bar to theproceedings.” The Tribunal has thus held that China’s non-participation does not prevent thearbitration from continuing. The Tribunal has also observed that China is still a Party to thearbitration and, pursuant to the terms of Article 296(1) of the Convention and Article 11 of3

The South China Sea Arbitration
Award of 12 July 2016

Annex VII, shall be bound by any award the Tribunal issues.

The situation of anon-participating Party, however, imposes a special responsibility on the Tribunal. It cannot, in
China’s absence, simply accept the Philippines’ claims or enter a default judgment. Rather,
Article 9 requires the Tribunal, before making its award, to satisfy itself “not only that it has
jurisdiction over the dispute but also that the claim is well founded in fact and law.”
13.

Despite its decision not to appear formally at any point in these proceedings, China has taken
steps to informally make clear its view that the Tribunal lacks jurisdiction to consider any of thePhilippines’ claims. On 7 December 2014, China’s Foreign Ministry published a “Position
Paper of the Government of the People’s Republic of China on the Matter of Jurisdiction in theSouth China Sea Arbitration Initiated by the Republic of the Philippines” (“China’s Position
Paper”). 2 In its Position Paper, China argued that the Tribunal lacks jurisdiction because(a) “[t]he essence of the subject-matter of the arbitration is the territorial sovereignty over the
relevant maritime features in the South China Sea”; (b) “China and the Philippines have agreed,through bilateral instruments and the Declaration on the Conduct of Parties in the South China
Sea, to settle their relevant disputes through negotiations”; and (c) the disputes submitted by thePhilippines “would constitute an integral part of maritime delimitation between the twocountries.” The Chinese Ambassador to the Netherlands has also sent several communications
to the individual members of the Tribunal, directly and via the Registry, to draw certain
statements of Foreign Ministry officials and others to the attention of the arbitrators, while at thesame time making clear that such communications should not be interpreted as China’s
participation in the arbitral proceedings.

14.

The Tribunal decided to treat the Position Paper and communications from China as equivalent
to an objection to jurisdiction and to conduct a separate hearing and rule on its jurisdiction as apreliminary question, except insofar as an issue of jurisdiction “does not possess an exclusively
preliminary character.”

The Tribunal issued its Award on Jurisdiction and Admissibility(the “Award on Jurisdiction”) on 29 October 2015, addressing the objections to jurisdiction
set out in China’s Position Paper, as well as other questions concerning the scope of the
Tribunal’s jurisdiction. In its Award on Jurisdiction, the Tribunal reached conclusions withrespect to seven of the Philippines’ fifteen Submissions while deferring decisions on seven otherSubmissions for further consideration in conjunction with the merits of the Philippines’ claims.
The Tribunal also requested the Philippines to clarify one of its Submissions. Those questions

4The South China Sea Arbitration
Award of 12 July 2016

regarding the scope of the Tribunal’s jurisdiction that were not decided in the Award on
Jurisdiction have all been considered and are addressed in the course of this Award.
15.

The Tribunal outlined in its Award on Jurisdiction the steps it took to satisfy itself of its
jurisdiction, including treating China’s communications as a plea on jurisdiction, bifurcating the
dispute to have a separate hearing and exchange of questions and answers on issues ofjurisdiction and admissibility, probing the Philippines on jurisdictional questions beyond eventhose in China’s Position Paper, and in relation to the seven matters not decided in the Award
on Jurisdiction, deferring for later consideration those jurisdictional issues so intertwined withthe merits that they lacked an exclusively preliminary character. In the merits phase of the
dispute, as set out in more detail elsewhere in this Award, the Tribunal has been particularly
vigilant with respect to establishing whether the Philippines’ claims are well founded in fact andlaw. It has done so, for example, by retaining independent experts on technical matters raisedby the Philippines’ pleadings; inviting comments from both Parties on materials that were notoriginally part of the record submitted to the Tribunal by the Philippines; and posing questions
to the Philippines’ counsel and experts before, during, and after the hearing on the merits thatwas held in The Hague from 24 to 30 November 2015. While China did not attend the hearing,
it was provided with daily transcripts and all documents submitted during the course of thehearing and was given an opportunity to comment thereon. In addition to a large delegationfrom the Philippines, representatives from Australia, the Republic of Indonesia, Japan,
Malaysia, Singapore, the Kingdom of Thailand, and the Socialist Republic of Viet Nam
attended the hearing as observers.

16.

In this Award, the Tribunal addresses those matters of jurisdiction and admissibility thatremained outstanding after the Award on Jurisdiction, as well as the merits of those of thePhilippines’ claims for which the Tribunal has jurisdiction. The Award is structured as follows.

17.

Chapter II sets out the procedural history of the arbitration, focusing on the events which
postdate the issuance of the Award on Jurisdiction. The Chapter demonstrates that, in line with
the Tribunal’s duty under Article 5 of Annex VII to “assure each party a full opportunity to beheard and to present its case,” the Tribunal has communicated to both Parties all developmentsin this arbitration and provided them with the opportunity to comment on substance andprocedure.

The Tribunal has consistently reminded China that it remained open to it toparticipate at any stage, and has taken note of its Position Paper, public statements, and multiple
communications from its Ambassador to the Netherlands. The Tribunal has also taken steps, inline with its duty under Article 10 of the Rules of Procedure, to “avoid unnecessary delay andexpense and to provide a fair and efficient process for resolving the Parties’ dispute.”

5The South China Sea Arbitration
Award of 12 July 201618.

Chapter III sets out the Philippines’ requests for relief, including the fifteen final Submissions
as amended on 30 November 2015, with leave from the Tribunal communicated on
16 December 2015.

This Chapter notes that while China has not participated in theproceedings, the Tribunal has sought to discern from China’s official statements its position oneach of the Philippines’ claims.
19.

Chapter IV covers preliminary matters. It details the legal and practical consequences ofChina’s non-participation, summarises and incorporates the findings in the Award on
Jurisdiction, and addresses the status and effect of that Award and China’s reaction to it.

20.

In Chapter V, the Tribunal considers the Philippines’ requests for a declaration that the Parties’
respective rights and obligations in regard to the waters, seabed, and maritime features of theSouth China Sea are governed by the Convention (the Philippines’ Submission No. 1), and for adeclaration that China’s claims to sovereign and historic rights with respect to the maritime
areas encompassed by the ‘nine-dash line’ are contrary to the Convention and therefore without
lawful effect (the Philippines’ Submission No. 2).

21.

In Chapter VI, the Tribunal addresses the Philippines’ requests concerning the status of, andmaritime entitlements generated by, certain maritime features in the South China Sea(the Philippines’ Submissions No. 3 to 7), namely Cuarteron Reef, Fiery Cross Reef, the Gaven
Reefs, Johnson Reef, Hughes Reef, McKennan Reef, Mischief Reef, Scarborough Shoal,
Second Thomas Shoal, and Subi Reef.

In arriving at its decisions on Submissions

No. 3, 5 and 7, the Tribunal also addresses in Chapter VI whether any feature in the Spratly
Islands constitutes a fully entitled island, capable in its natural condition of sustaining humanhabitation or an economic life of its own within the meaning of Article 121(3) of theConvention, such as to be entitled to potential maritime zones that could overlap with those of
the Philippines.
22.

In Chapter VII, the Tribunal considers the various allegations by the Philippines that China has
violated provisions of the Convention, including with respect to:(a)

China’s interference with the Philippines’ sovereign rights over non-living and living
resources (the Philippines’ Submission No. 8);(b)

China’s failure to prevent exploitation of the Philippines’ living resources by Chinese
fishing vessels (the Philippines’ Submission No. 9);(c)China’s interference with the traditional fishing activities of Philippine fishermen at
Scarborough Shoal (the Philippines’ Submission No. 10);
6

The South China Sea Arbitration
Award of 12 July 2016(d)

China’s failure to protect and preserve the marine environment through (a) its tolerance
and active support of Chinese fishing vessels harvesting endangered species and engaging
in harmful fishing methods; and (b) its extensive land reclamation, artificial
island-building, and construction activities at seven coral reefs in the Spratly Islands(the Philippines’ Submissions No. 11 and 12(b));(e)

China’s construction of artificial islands, installations, and structures at Mischief Reef
without the Philippines’ authorisation (the Philippines’ Submissions No. 12(a) and 12(c));
and

(f)

China’s operation of its law enforcement vessels in such a way as to create serious risk ofcollision and danger to Philippine vessels in the vicinity of Scarborough Shoal during two
incidents in April and May 2012 (the Philippines’ Submission No. 13).

23.

In Chapter VIII, the Tribunal considers the Philippines’ claim that China has, through its
activities near Second Thomas Shoal and its artificial island-building activities at seven coral reefs
in the Spratly Islands, aggravated and extended the Parties’ disputes since the commencement of
the arbitration (the Philippines’ Submission No. 14).

24.

Chapter IX examines the Philippines’ Submission No. 15 on the future conduct of the Parties anddiscusses the obligations on both Parties going forward to resolve their disputes peacefully and tocomply with the Convention and this Award in good faith.

25.

Chapter X sets out the Tribunal’s formal decisions.

PROCEDURAL HISTORY

26.

The Award on Jurisdiction recounts in detail the procedural history of the arbitration from its
commencement up until the date on which the Award on Jurisdiction was issued. In thisAward, the Tribunal will focus on procedural events which occurred after the issuance of theAward on Jurisdiction.

27.

Article 5 of Annex VII to the Convention provides that the Tribunal has a duty to “assur[e] toeach party a full opportunity to be heard and to present its case.” In line with this duty, and as
the procedural history chapters in both Awards demonstrate, the Tribunal has communicated to
the Philippines and China all developments in this arbitration and provided them with theopportunity to comment on substance and procedure. The Tribunal consistently reminded
China that it remained open to it to participate in these proceedings at any stage. It has also
taken steps to ensure that the Philippines is not disadvantaged by China’s non-appearance andhas conducted the proceedings in line with its duty under Article 10(1) of the Rules ofProcedure, “so as to avoid unnecessary delay and expense and to provide a fair and efficient
process for resolving the Parties’ dispute.”A.

INITIATION OF THE ARBITRATION

28.

By Notification and Statement of Claim dated 22 January 2013, the Philippines initiatedarbitration proceedings against China pursuant to Articles 286 and 287 of the Convention and inaccordance with Article 1 of Annex VII of the Convention. The Philippines stated that it seeksan Award that:(1)declares that the Parties’ respective rights and obligations in regard to the waters,
seabed and maritime features of the South China Sea are governed by UNCLOS,
and that China’s claims based on its “nine dash line” are inconsistent with theConvention and therefore invalid;(2)

determines whether, under Article 121 of UNCLOS, certain of the maritime features
claimed by both China and the Philippines are islands, low tide elevations orsubmerged banks, and whether they are capable of generating entitlement tomaritime zones greater than 12 M; and(3)enables the Philippines to exercise and enjoy the rights within and beyond its
exclusive economic zone and continental shelf that are established in theConvention.3

The Philippines stressed that it:
does not seek in this arbitration a determination of which Party enjoys sovereignty over theislands claimed by both of them. Nor does it request a delimitation of any maritime

boundaries. The Philippines is conscious of China’s Declaration of 25 August 2006 under
Article 298 of UNCLOS, and has avoided raising subjects or making claims that China has,by virtue of that Declaration, excluded from arbitral jurisdiction.429.

In response, China presented a Note Verbale to the Department of Foreign Affairs of thePhilippines on 19 February 2013, rejecting the arbitration and returning the Notification andStatement of Claim to the Philippines.5 In its Note Verbale, China stated that its position on theSouth China Sea issues “has been consistent and clear” and that “[a]t the core of the disputes
between China and the Philippines in the South China Sea are the territorial disputes over someislands and reefs of the Nansha Islands.” China noted that “[t]he two countries also haveoverlapping jurisdictional claims over parts of the maritime area in the South China Sea” andthat both sides had agreed to settle the dispute through bilateral negotiations and friendly
consultations.

B.

CONSTITUTION OF THE TRIBUNAL AND APPOINTMENT OF THE PCA AS REGISTRY

30.

As detailed in the Award on Jurisdiction, the Philippines appointed Judge Rüdiger Wolfrum, aGerman national, as a member of the Tribunal in accordance with Article 3(b) of Annex VII to
the Convention. As China did not appoint an arbitrator, the President of the International
Tribunal for the Law of the Sea, pursuant to Articles 3(c) and 3(e) of Annex VII to theConvention, appointed Judge Stanislaw Pawlak, a national of Poland, as the second arbitrator.
In accordance with Articles 3(d) and 3(e) of Annex VII to the Convention, the President of theInternational Tribunal for the Law of the Sea also appointed the remaining three arbitrators,
namely Judge Jean-Pierre Cot, a national of France; Professor Alfred H.A. Soons, a national of
the Netherlands; and as the Presiding Arbitrator, Judge Thomas A. Mensah, a national of
Ghana. The present Tribunal was constituted on 21 June 2013.

31.

On 12 July 2013, the Tribunal issued Administrative Directive No. 1, pursuant to which the
Tribunal appointed the Permanent Court of Arbitration as Registry and set in placearrangements for a deposit to cover fees and expenses. On 15 July 2013, the Secretary-Generalof the PCA informed the Tribunal and the Parties that Ms. Judith Levine, PCA Senior LegalCounsel, had been appointed to serve as Registrar. Copies of Administrative Directive No. 1, aswith all subsequent documents issued by the Tribunal and correspondence issued on its behalfby the Registry, were transmitted to the Agent and Counsel for the Philippines, and the Embassyof the People’s Republic of China in the Kingdom of the Netherlands (the “Chinese

Throughout the proceedings, the Chinese Embassy has returned thecommunications and reiterated that “it will neither accept nor participate in the arbitration
unilaterally initiated by the Philippines.”
32.

On 27 August 2013, the Tribunal issued Procedural Order No. 1, by which it adopted the Rulesof Procedure and fixed 30 March 2014 as the date for the Philippines to submit a Memorial that“shall fully address all issues including matters relating to jurisdiction, admissibility, and themerits of the dispute” (the “Memorial”).

C.

WRITTEN ARGUMENTS33.

On 11 March 2014, the Tribunal granted leave pursuant to Article 19 of the Rules of Procedure
for the Philippines to amend its Statement of Claim, which added a request to determine thestatus of Second Thomas Shoal.634.

On 30 March 2014, pursuant to Procedural Order No. 1, the Philippines submitted its Memorial
and accompanying annexes, addressing all aspects of the case including issues of jurisdiction,
admissibility, and the merits. The Memorial concluded with 15 specific submissions setting out
the relief sought by the Philippines (the “Submissions”), which are reproduced in their final andamended version in Chapter III below.7

35.

On 7 April 2014, the Philippines wrote further to the Tribunal regarding “China’s most recent
actions in and around Second Thomas (Ayungin) Shoal.” This followed an earlier complaintthat the Philippines had submitted to the Tribunal on 18 March 2014 concerning “recent actionsof China to prevent the rotation and resupply of Philippine personnel stationed at Second
Thomas (Ayungin) Shoal.” The Philippines wrote again to the Tribunal on 30 July 2014,expressing concern about China’s activities at several features in the South China Sea, inparticular the land reclamation at McKennan Reef, Hughes Reef, Johnson Reef, the Gaven
Reefs, and Cuarteron Reef. These complaints to the Tribunal are set out in more detail at
Chapter VIII on aggravation of the dispute.

On 5 December 2014, the Vietnamese Embassy sent to the Tribunal a “Statement of the

Award of 12 July 2016of China” and annexed documents (“Viet Nam’s Statement”).

Viet Nam’s Statement

requested that the Tribunal give due regard to the position of Viet Nam with respect to:(a) advocating full observance and implementation of all rules and procedures of theConvention, including Viet Nam’s position that it has “no doubt that the Tribunal has jurisdictionin these proceedings”; (b) preserving Viet Nam’s “rights and interests of a legal nature”;(c) noting that the Philippines does not request this Tribunal to consider issues not subject to its
jurisdiction under Article 288 of the Convention (namely questions of sovereignty and maritime
delimitation); (d) “resolutely protest[ing] and reject[ing]” any claim by China based on the“nine-dash line”; and (e) supporting the Tribunal’s competence to interpret and apply Articles
60, 80, 194(5), 206, 293(1), and 300 of the Convention and other relevant instruments.
Viet Nam stated that none of the maritime features referred to by the Philippines in theseproceedings can “generate maritime entitlements in excess of 12 nautical miles since they are
low-tide elevations or ‘rocks which cannot sustain human habitation or economic life of theirown’ under Article 121(3) of the Convention.” Viet Nam reserved “the right to seek tointervene if it seems appropriate and in accordance with the principles and rules of internationallaw, including the relevant provisions of UNCLOS.” Viet Nam also asked to receive copies of
all relevant documents in the arbitration.8
37.

On 7 December 2014, the Ministry of Foreign Affairs of the People’s Republic of China
published a “Position Paper of the Government of the People’s Republic of China on the Matterof Jurisdiction in the South China Sea Arbitration Initiated by the Republic of the Philippines,”
copies of which the Chinese Embassy deposited with the PCA for distribution to members of
the Tribunal. 9

The Chinese Embassy expressed in a Note Verbale that “[t]he Chinese

Government reiterates that it will neither accept nor participate in the arbitration unilaterally
initiated by the Philippines. The Chinese Government hereby makes clear that the forwardingof the aforementioned Position Paper shall not be regarded as China’s acceptance of or its
participation in the arbitration.”38.

The Tribunal conveyed copies of China’s Position Paper and Viet Nam’s Statement to theParties on 11 December 2014 and invited their comments.

(hereinafter “Viet Nam’s Statement”). As noted in the Award on Jurisdiction, the Tribunal had granted
Viet Nam access to copies of the Memorial, after seeking the views of the Parties, on 24 April 2014.

The South China Sea Arbitration
Award of 12 July 201639.

On 16 December 2014, the Tribunal issued Procedural Order No. 3, which established atimetable for further written submissions from both Parties and annexed a Request for Further
Written Argument by the Philippines Pursuant to Article 25(2) of the Rules of Procedure (the“Request for Further Written Argument”). The Request for Further Written Argument
included specific questions relating to admissibility, jurisdiction, and the merits of the disputeand invited comments on any relevant public statements made by Chinese Government officials
or others.

40.

In a letter accompanying Procedural Order No. 3, the Tribunal invited the Parties’ comments on
certain procedural matters, including (a) the possible bifurcation of the proceedings to address
the Tribunal’s jurisdiction as a preliminary matter, (b) the possible appointment of an expert
hydrographer, (c) the possibility of a site visit as contemplated in Article 22 of the Rules ofProcedure, (d) the appropriate procedure with regard to any amicus curiae submissions that the
Tribunal may receive, and (e) the scheduling of a hearing in July 2015.

41.

On 26 January 2015, the Philippines sent the Tribunal its comments on Viet Nam’s requests,
supporting Viet Nam having access to documents in the interest of transparency. On the sameday, the Philippines also (a) conveyed its position that it opposed bifurcation; (b) supported theappointment of a technical expert and made suggestions as to the appropriate profile for an
expert; (c) commented that a site visit “would be useful” provided arrangements were made forit to occur “under secure conditions” but acknowledged the “fact that conducting a site visit in
the context of this case would present certain challenges, not least because of China’s decision
not to participate”; (d) commented that any decision on accepting an amicus curiae submission
would fall within the Tribunal’s inherent power and under Article 1(2) of the Rules ofProcedure and suggested “that each amicus submission should be evaluated on its own merits,
to determine whether there is ‘sufficient reason’ for it to be accepted,” so long as it does notdelay or disrupt the proceedings; and (e) commented on the dates and scope of an oral hearing.

42.

On 6 February 2015, the Chinese Ambassador to the Kingdom of the Netherlands wrote
individually to the members of the Tribunal, setting out “the Chinese Government’s position on
issues relating to the South China Sea arbitration initiated by the Philippines.” The letter
described China’s Position Paper as having “comprehensively explain[ed] why the Arbitral
Tribunal . . . manifestly has no jurisdiction over the case.” The letter also stated that the
Chinese Government “holds an omnibus objection to all procedural applications or steps thatwould require some kind of response from China.” The letter further clarified that China’s
non-participation and non-response to any issue raised by the Tribunal “shall not be understoodor interpreted by anyone in any sense as China’s acquiescence in or non-objection to any and all

15

The South China Sea Arbitration
Award of 12 July 2016

procedural or substantive matters already or might be raised by the Arbitral Tribunal.” Theletter further expressed China’s “firm opposition” to some of the procedural items raised in the
Tribunal’s correspondence, such as “intervention by other States,” “amicus curiae
submissions,” and “site visit[s]”. Finally, the letter recalled the commitment of China andcountries of the Association of Southeast Asian Nations (“ASEAN”) to resolving disputes
through consultation and negotiation and expressed the hope that “all relevant actors will act ina way that contributes to peaceful settlement of the South China Sea disputes, cooperation
among the coastal States of the South China Sea and the maintenance of peace and stability in
the South China Sea.”
43.

On 17 February 2015, the Tribunal authorised the Registry to provide Viet Nam with a copy ofProcedural Order No. 3 and the Tribunal’s accompanying Request for Further Written
Argument. The Tribunal stated that it would address the permissibility of intervention in theseproceedings “only in the event that Viet Nam in fact makes a formal application for suchintervention.”

44.

The Philippines submitted its Supplemental Written Submission and accompanying annexes(the “Supplemental Written Submission”) on 16 March 2015.

D.

BIFURCATION OF PROCEEDINGS45.

On 21 April 2015, the Tribunal issued Procedural Order No. 4, in which it considered thecommunications of China, including China’s Position Paper, effectively to “constitute a plea
concerning this Arbitral Tribunal’s jurisdiction for the purposes of Article 20 of the Rules ofProcedure.” The Tribunal thus decided to convene a hearing to consider issues of jurisdiction
and admissibility from 7 to 13 July 2015 (the “Hearing on Jurisdiction”). In Procedural OrderNo. 4, the Tribunal stated that if it determined after the Hearing on Jurisdiction “that there arejurisdictional objections that do not possess an exclusively preliminary character, then, in
accordance with Article 20(3) of the Rules of Procedure, such matters will be reserved forconsideration and decision at a later stage of the proceedings.”

46.

On 21 May 2015, the Tribunal received a letter from the Philippines which described China’s“current[] engage[ment] in a massive land reclamation project at various features in the South
China Sea” as “deeply troubling to the Philippines” and submitted that such actions were in“violation of the Philippines’ rights and in disregard of . . . China’s duty not to cause serious
harm to the marine environment.” In light of such developments, the Philippines suggested thata merits hearing be provisionally scheduled at the earliest possible date.

16

HEARING ON JURISDICTION AND ADMISSIBILITY

47.

On 2 June 2015, the Tribunal confirmed the schedule for the Hearing on Jurisdiction. The
Tribunal advised that the hearing would not be open to the general public, but that it would
consider allowing representatives of interested States to attend upon receipt of a written request.

48.

No comments had been received from China by 16 June 2015, the date set by Procedural OrderNo. 3 for China’s comments on the Philippines’ Supplemental Written Submission.

49.

In line with its duty to satisfy itself that it has jurisdiction, the Tribunal did not limit the hearing
to the issues raised in China’s Position Paper, and on 23 June 2015, the Tribunal sent the Parties
a list of issues as guidance for the Hearing on Jurisdiction.

50.

Throughout June and July 2015, the Tribunal received requests from several States, interested in
the arbitration, for copies of relevant documents and for permission to attend the Hearing on
Jurisdiction. After seeking the views of the Parties on each occasion, the Tribunal granted such
requests from Malaysia, Japan, Viet Nam, Indonesia, Thailand, and Brunei.

51.

On 1 July 2015, the Chinese Ambassador to the Kingdom of the Netherlands sent a second letterto the members of the Tribunal recalling China’s “consistent policy and practice of [resolving]
the disputes related to territory and maritime rights and interests with States directly concerned
through negotiation and consultation” and noting China’s “legitimate right” under theConvention not to “accept any imposed solution or any unilateral resorting to a third-party
settlement,” a right that it considered the Philippines breached by initiating the arbitration. The
Ambassador stated that his letters and the Chinese Government’s statements “shall by no means
be interpreted as China’s participation in the arbitral proceeding” and that China “opposes any
moves to initiate and push forward the arbitral proceeding, and does not accept any arbitralarrangements, including the hearing procedures.”

52.

The Hearing on Jurisdiction took place from 7 to 13 July 2015 at the Peace Palace in
The Hague. A list of attendees is contained in the Award on Jurisdiction. Copies of the dailytranscripts, questions from the Members of the Tribunal, answers from the Philippines and allmaterials submitted during the hearing were made available to both Parties. A press release wasissued by the Registry at the close of the hearing and the transcripts were subsequently
published.

53.

On 23 July 2015, the Philippines filed written responses to questions posed by the Tribunal.
China did not respond to the invitation to submit by 17 August 2015, comments on mattersraised during or after the Hearing on Jurisdiction.
17

However, on 24 August 2015, China

The South China Sea Arbitration
Award of 12 July 2016

published “Foreign Ministry Spokesperson Hua Chunying’s Remarks on the Release of theTranscript of the Oral Hearing on Jurisdiction by the South China Sea Arbitral Tribunal
Established at the Request of the Philippines.” The spokesperson recalled that China had“consist[e]ntly expounded its position of neither accepting nor participating in the South China
Sea arbitration unilaterally initiated by the Philippines” and that China’s Position Paper had“pointed out that the Arbitral Tribunal . . . has no jurisdiction over the case and elaborated on
the legal grounds for China’s non-acceptance and non-participation in the arbitration.”10
F.

PROVISIONAL SCHEDULING OF HEARING ON THE MERITS AND APPOINTMENT OF EXPERT54.

Article 24(1) of the Arbitral Tribunal’s Rules of Procedure provides:
After seeking the views of the Parties, the Arbitral Tribunal may appoint one or more
independent experts. That expert may be called upon to report on specific issues and in themanner to be determined by the Arbitral Tribunal. A copy of the expert’s terms ofreference, established by the Arbitral Tribunal, shall be communicated to the Parties.

55.

Previously, in December 2014, the Tribunal had invited the Parties’ views on the utility andtiming of appointing an expert hydrographer, as well as the qualifications appropriate for suchan expert. The Chinese Ambassador’s letter of 6 February 2015 did not expressly address thisquestion.

The Philippines considered it desirable for the Tribunal to appoint as soon as

convenient a “knowledgeable, independent, and impartial hydrographer” from whose input“many issues in dispute . . . would benefit significantly.” The Philippines set out a list of
appropriate qualifications.
56.

On 21 April 2015, when the Tribunal issued Procedural Order No. 4 bifurcating proceedings,
the Tribunal invited the Parties’ views as to whether it should, without prejudice to any findings
on jurisdiction and admissibility, proceed to: (a) reserve a period of time within the next 6 to 12
months for a subsequent merits hearing should it become necessary; (b) take steps already toascertain the availability of potential technical experts. In so doing, the Tribunal recalled its
duty under Article 10(1) of the Rules of Procedure to “conduct the proceedings so as to avoid
unnecessary delay and expense and to provide a fair and efficient process for resolving theParties’ dispute.”

57.

The Philippines, by letter dated 11 May 2015, noted that the week of 23 to 27 November 2015
would be suitable for a hearing on the merits and considered that engaging a technical expert
early would help to avoid unnecessary delay and that no prejudice would be suffered as a result

did not comment on either matter.
58.

The Tribunal informed the Parties on 7 August 2015 that, after reviewing a number ofcandidates, it proposed to appoint Mr. Grant Boyes (a national of Australia) as the Tribunal’s
expert hydrographer. The Parties were invited to comment on his curriculum vitae, declarationof independence, and draft Terms of Reference.

The Philippines reported that it had noobjection, but proposed a clarification to the Terms of Reference that “[i]n providing the
Arbitral Tribunal with technical assistance . . . the Expert shall respect that it is the Arbitral
Tribunal, and not the Expert, that makes any determination as to legal questions, in particular
the application of Article 121(3) of the Convention.”With this clarification, and having

received no comments from China, the Tribunal and Mr. Boyes finalised the appointment.
59.

On 10 September 2015, the Parties were invited to comment on a provisional schedule for a
merits hearing to take place between 24 to 30 November 2015 and also on a request from theEmbassy of the Republic of Singapore in Brussels seeking observer status at any future hearing.
The Philippines agreed with the proposed schedule and, consistent with its position in support oftransparency, expressed that it had no objection to the attendance of a Singaporean delegation at
any future hearings. China did not comment on the proposals and, consistent with its practicethroughout the proceedings, returned the correspondence to the Registry and reiterated its
position of non-acceptance and non-participation.

G.

ISSUANCE OF AWARD ON JURISDICTION AND ADMISSIBILITY60.

On 29 October 2015, the Tribunal issued its Award on Jurisdiction, the key findings of which
are summarised in Chapter IV below. The Award, which was unanimous, only addressed
matters of jurisdiction and admissibility; it did not address the merits of the Parties’ dispute. In
the dispositif, the Tribunal:A.

FINDS that the Tribunal was properly constituted in accordance with Annex VII to
the Convention.

B.

FINDS that China’s non-appearance in these proceedings does not deprive the
Tribunal of jurisdiction.

C.

FINDS that the Philippines’ act of initiating this arbitration did not constitute anabuse of process.

D.

FINDS that there is no indispensable third party whose absence deprives the
Tribunal of jurisdiction.

E.

FINDS that the 2002 China–ASEAN Declaration on Conduct of the Parties in theSouth China Sea, the joint statements of the Parties referred to in paragraphs 231 to
232 of this Award, the Treaty of Amity and Cooperation in Southeast Asia, and theConvention on Biological Diversity, do not preclude, under Articles 281 or 282 of

19

The South China Sea Arbitration
Award of 12 July 2016

the Convention, recourse to the compulsory dispute settlement procedures available
under Section 2 of Part XV of the Convention.

61.

F.

FINDS that the Parties have exchanged views as required by Article 283 of theConvention.

G.

FINDS that the Tribunal has jurisdiction to consider the Philippines’ Submissions
No. 3, 4, 6, 7, 10, 11, and 13, subject to the conditions noted in paragraphs 400, 401,
403, 404, 407, 408, and 410 of this Award.

H.

FINDS that a determination of whether the Tribunal has jurisdiction to consider thePhilippines’ Submissions No. 1, 2, 5, 8, 9, 12, and 14 would involve consideration ofissues that do not possess an exclusively preliminary character, and accordingly
RESERVES consideration of its jurisdiction to rule on Submissions No. 1, 2, 5, 8, 9,
12, and 14 to the merits phase.

I.

DIRECTS the Philippines to clarify the content and narrow the scope of its
Submission 15 and RESERVES consideration of its jurisdiction over Submission
No. 15 to the merits phase.

J.

RESERVES for further consideration and directions all issues not decided in thisAward.11

The Tribunal confirmed that it was ready to proceed in late November with a hearing on the
merits and any outstanding questions of jurisdiction and admissibility (the “Hearing on the
Merits”) and stated that it was willing to make appropriate adjustments to the schedule if China
decided to participate. The Philippines confirmed the schedule, and China did not comment on
it. However, on 30 October 2015, the Chinese Ministry of Foreign Affairs issued a “Statement. . . on the Award on Jurisdiction and Admissibility of the South China Sea Arbitration by the
Arbitral Tribunal Established at the Request of the Republic of the Philippines” as follows:
The award rendered on 29 October 2015 by the Arbitral Tribunal established at the requestof the Republic of the Philippines (hereinafter referred to as the “Arbitral Tribunal”) on
jurisdiction and admissibility of the South China Sea arbitration is null and void, and has nobinding effect on China.
I. China has indisputable sovereignty over the South China Sea Islands and the adjacentwaters. China’s sovereignty and relevant rights in the South China Sea, formed in the long
historical course, are upheld by successive Chinese governments, reaffirmed by China’s
domestic laws on many occasions, and protected under international law including
the United Nations Convention on the Law of the Sea (UNCLOS). With regard to theissues of territorial sovereignty and maritime rights and interests, China will not accept any
solution imposed on it or any unilateral resort to a third-party dispute settlement.
II. The Philippines’ unilateral initiation and obstinate pushing forward of the South China
Sea arbitration by abusing the compulsory procedures for dispute settlement under the
UNCLOS is a political provocation under the cloak of law. It is in essence not an effort tosettle disputes but an attempt to negate China’s territorial sovereignty and maritime rights
and interests in the South China Sea. In the Position Paper of the Government of thePeople’s Republic of China on the Matter of Jurisdiction in the South China Sea Arbitration
Initiated by the Republic of the Philippines, which was released by the Chinese Ministry ofForeign Affairs on 7 December 2014 upon authorization, the Chinese government pointed
out that the Arbitral Tribunal manifestly has no jurisdiction over the arbitration initiated by
the Philippines, and elaborated on the legal grounds for China’s non-acceptance of andnon-participation in the arbitration. This position is clear and explicit, and will not change.

11

Award on Jurisdiction, para. 413.

20

The South China Sea Arbitration
Award of 12 July 2016

III. As a sovereign state and a State Party to the UNCLOS, China is entitled to choose themeans and procedures of dispute settlement of its own will. China has all along beencommitted to resolving disputes with its neighbors over territory and maritime jurisdiction
through negotiations and consultations. Since the 1990s, China and the Philippines haverepeatedly reaffirmed in bilateral documents that they shall resolve relevant disputes
through negotiations and consultations. The Declaration on the Conduct of Parties in theSouth China Sea (DOC) explicitly states that the sovereign states directly concerned
undertake to resolve their territorial and jurisdictional disputes by peaceful means throughfriendly consultations and negotiations. All these documents demonstrate that China andthe Philippines have chosen, long time ago, to settle their disputes in the South China Sea
through negotiations and consultations. The breach of this consensus by the Philippines
damages the basis of mutual trust between states.
IV. Disregarding that the essence of this arbitration case is territorial sovereignty andmaritime delimitation and related matters, maliciously evading the declaration on optional
exceptions made by China in 2006 under Article 298 of the UNCLOS, and negating theconsensus between China and the Philippines on resolving relevant disputes throughnegotiations and consultations, the Philippines and the Arbitral Tribunal have abused
relevant procedures and obstinately forced ahead with the arbitration, and as a result, haveseverely violated the legitimate rights that China enjoys as a State Party to the UNCLOS,
completely deviated from the purposes and objectives of the UNCLOS, and eroded theintegrity and authority of the UNCLOS. As a State Party to the UNCLOS, China firmly
opposes the acts of abusing the compulsory procedures for dispute settlement under the
UNCLOS, and calls upon all parties concerned to work together to safeguard the integrity
and authority of the UNCLOS.
V. The Philippines’ attempt to negate China’s territorial sovereignty and maritime rights
and interests in the South China Sea through arbitral proceeding will lead to nothing. Chinaurges the Philippines to honor its own commitments, respect China’s rights underinternational law, change its course and return to the right track of resolving relevant
disputes in the South China Sea through negotiations and consultations. 12

62.

On 6 November 2015, the observer States that had attended the Hearing on Jurisdiction, as wellas Brunei and Singapore, were advised of the schedule for the Hearing on the Merits and thatthey could send delegations of up to five representatives as observers.

63.

As it had done before the Hearing on Jurisdiction, the Tribunal provided on 10 November 2015
an “Annex of Issues the Philippines May Wish to Address” as guidance for the Hearing on the
Merits.

64.

On 6 November 2015, the Philippines sought leave to present for examination two experts,
Professor Clive Schofield and Professor Kent Carpenter; and on 14 November 2015, sought
leave to supplement its written pleadings with additional documentary and testimonial evidence
and legal authorities which it intended to reference during the Hearing on the Merits. The
Tribunal invited China’s comments on the requests by 17 November 2015.

21

The South China Sea Arbitration
Award of 12 July 201665.

On 18 November 2015, the Tribunal granted both requests, noting that it had not received
comments from China, and that the requests were reasonable. The Tribunal also invited theParties’ comments on whether copies of the 10 November 2015 Annex of Issues could be
provided to observer States who had confirmed attendance at the Hearing on the Merits (namely
Viet Nam, Malaysia, Thailand, Japan, Indonesia and Singapore).

Finally, the Tribunal

forwarded to the Parties for their comment a Note Verbale from the Embassy of the UnitedStates of America, requesting to send a representative to observe the hearing. The Note Verbale
explained that “[a]s a major coastal and maritime State, and as a State that is continuing topursue its domestic Constitutional processes to accede to the United Nations Convention on the
Law of the Sea, the United States has a keen interest in the proceedings in light of the important
legal issues relating to the law of the sea that are the subject of the arbitration.”
66.

The Philippines wrote on 19 November 2015 that it did not object to the U.S. request, nor toproviding the Annex of Issues to observer delegations. The Philippines also submitted the
additional documentary and testimonial evidence and legal authorities for which it had been
granted leave. Copies were provided to the Chinese Embassy.

67.

On 23 November 2015, the Tribunal communicated to the Parties and the U.S. Embassy that it
had decided that “only interested States parties to the United Nations Convention on the Law of
the Sea will be admitted as observers” and thus could not accede to the U.S. request. The sameday, the Tribunal received a Note Verbale from the United Kingdom’s Embassy in the
Netherlands applying for “neutral observer status” at the Hearing on the Merits and explainingthat “[a]s a State Party to the [Convention], and with a strong interest in the maintenance ofpeace and stability in the South China Sea, underpinned by respect for, and adherence to,international law, the United Kingdom has been closely following proceedings in the arbitrationand has an ongoing interest in developments.” The request was forwarded to the Parties fortheir comment, and the Philippines stated it had no objection to it.

68.

On 24 November 2015, the Tribunal received a request from the Australian Embassy to observe
the Hearing on the Merits. The request stated that “Australia has taken a close interest in thiscase. Australia has the third largest maritime jurisdiction in the world, and a significant
proportion of our global seaborne trade passes through the South China Sea. As one of theoriginal States Parties to [the Convention], Australia has an abiding national interest inpromoting the rule of law regionally and globally, including through the peaceful settlement ofdisputes in accordance with international law.” The request was forwarded to the Parties fortheir immediate comment. The Philippines did not object to the Australian request. The
Tribunal informed the embassies of Australia and the United Kingdom that their respective

22

Award of 12 July 2016

requests to send observer delegations had been granted, and so advised the Parties. The United
Kingdom, however, informed the Registry that it would not be attending the proceedings.

The South China Sea Arbitration
Award of 12 July 201671.

Oral presentations were made by the then Solicitor General Florin T. Hilbay, then Agent of thePhilippines; Secretary Albert F. del Rosario, the then Secretary of Foreign Affairs of thePhilippines; Mr. Paul S. Reichler and Mr. Lawrence H. Martin of Foley Hoag LLP,
Washington, D.C.; Professor Bernard H. Oxman of the University of Miami; Professor Philippe
Sands QC of Matrix Chambers, London; Professor Alan E. Boyle of Essex Court Chambers,
London; and Mr. Andrew B. Loewenstein of Foley Hoag LLP, Boston.

72.

The Registry delivered daily transcripts to the Philippines’ delegation and to the Chinese
Embassy, along with copies of all materials submitted by the Philippines during the course of
their oral presentations.

73.

During the first round of oral argument, several questions were posed by individual arbitrators
and answered by the Philippines. On 27 November 2015, the Tribunal circulated to the Parties(a) “Questions for the Philippines to Address in the Second Round,” (b) “Questions forProfessor Schofield,” and (c) “Questions for Professor Carpenter.” Copies of the questions
were subsequently made available to the observer delegations.

74.

On 30 November 2015, during the second round of the hearing, the Philippines responded to the
Tribunal’s written questions circulated on 27 November 2015, as well as to oral questions posedby individual arbitrators. Professor Schofield and Professor Carpenter also responded to thewritten questions put to them respectively. The Philippines’ then Secretary for Foreign Affairs
addressed the Tribunal with concluding remarks, in which he recalled, on the 70th anniversary of
the United Nations, that two “centrepieces” of the UN order were the sovereign equality ofStates and the obligation to settle disputes by peaceful means.

He also noted the40th anniversary of the establishment of diplomatic relations between the Philippines and China
and stated that it was for the preservation of the valued friendship between the two States that
the Philippines had initiated this arbitration.

He expressed his belief that this arbitration“benefits everyone” because for China “it will define and clarify its maritime entitlements,” forthe Philippines, “it will clarify what is ours, specifically our fishing rights, rights to resources,
and rights to enforce our laws within our EEZ” and for the rest of the international community,“it will help ensure peace, security, stability and freedom of navigation and overflight in theSouth China Sea.” He expected the arbitration to “be instructive for other States to consider the
dispute settlement mechanism under UNCLOS as an option for resolving disputes in a peacefulmanner.” He summarised the key legal arguments and expressed hope that this arbitration
would help “promote[] peace, security and good neighbourliness” and accord to the rule of law

26

Award of 12 July 2016

the “primacy that the founders of the United Nations and the drafters of UNCLOS
envisioned.”1375.

The Agent for the Philippines formally presented the Philippines’ fifteen final Submissions.14
The Presiding Arbitrator outlined the next steps in the proceeding, including an invitation toboth Parties to submit by 9 December 2015 their corrections to the transcript, an invitation to
the Philippines to submit by 18 December 2015 any further responses to questions posed during
the second round, and an invitation to China to comment in writing by 1 January 2016 onanything said during the Hearing on the Merits or submitted subsequently. The Presiding
Arbitrator then declared the Hearing on the Merits closed.

76.

In keeping with its prior practice and in accordance with Article 16 of the Rules of Procedure,
the Registry issued a Press Release after the closure of the Hearing on the Merits.

I.

POST-HEARING PROCEEDINGS77.

The Agent for the Philippines submitted in written form the Final Submissions of the Republicof the Philippines on 30 November 2015.

78.

By letter dated 1 December 2015, the Tribunal noted that the Philippines’ final Submissions
reflected three amendments—to Submissions No. 11, 14 and 15—requested by the Philippines
in the course of the Hearing on the Merits.15 With respect to Submission No. 11, on failure toprotect and preserve the marine environment, the Philippines added references to Cuarteron
Reef, Fiery Cross Reef, Gaven Reef, Johnson Reef, Hughes Reef and Subi Reef. With respect
to Submission No. 14, on China’s alleged aggravation and extension of the dispute, thePhilippines added reference to “dredging, artificial island-building and construction activities at
Mischief Reef, Cuarteron Reef, Fiery Cross Reef, Gaven Reef, Johnson Reef, Hughes Reef andSubi Reef.” In response to the Tribunal’s direction in paragraph 413(I) of the Award on
Jurisdiction to “clarify the content and narrow the scope of its Submission 15,” the Philippineschanged the text of Submission No. 15 to seek a declaration that “China shall respect the rights
and freedoms of the Philippines under the Convention, shall comply with its duties under theConvention, including those relevant to the protection and preservation of the marine
environment in the South China Sea, and shall exercise its rights and freedoms in the South
China Sea with due regard to those of the Philippines under the Convention.” China was invited
to provide any comments on the requested amendments by 9 December 2015.

The South China Sea Arbitration
Award of 12 July 201679.

On 14 December 2015, the Philippines submitted documents that had been referenced orrequested during the hearing. These included electronic versions of materials displayed byProfessor Schofield, additional legal authorities, and observations by Dr. Robert Smith and
EOMAP satellite bathymetry analysis pertaining to the nature of certain maritime features
located between Thitu and Subi Reef.

80.

In accordance with Article 19 of the Rules of Procedure, on 16 December 2015, the Tribunal
granted leave to the Philippines to make the amendments incorporated in its final Submissions.
It also informed the Parties that the final reviewed and corrected transcripts of the Hearing on
the Merits would be published on the PCA’s website and reminded China of its opportunity tocomment in writing by 1 January 2016 on anything said during the hearing or subsequently filedby the Philippines.

81.

On 18 December 2015, the Philippines filed a supplementary response to one of Judge
Wolfrum’s questions posed during the Hearing on the Merits, referring to additional evidence
about the alleged taking of giant clams and sea turtles by Chinese fishermen and alleged
environmental damage to reefs.

82.

On 21 December 2015, an official spokesperson for the Chinese Ministry of Foreign Affairscommented on the publication of the transcript of the Hearing on the Merits as follows:
The Chinese side will neither accept nor participate in the South China Sea arbitration
unilaterally initiated by the Philippines. This longstanding position is fully supported byinternational law and subject to no change.
In the hearing, the Philippine side attempted to negate China’s sovereignty over the Nansha
Islands and deny the validity of the Cairo Declaration and the Potsdam Proclamation indisregard of historical facts, international law and international justice. It testifies to thefact that the South China Sea dispute between China and the Philippines is in essence aterritorial dispute over which the arbitral tribunal has no jurisdiction. It also shows that theso-called arbitration is a political provocation under the cloak of law aiming at negating
China’s sovereignty and maritime rights and interests in the South China Sea instead ofresolving the dispute.
It is the Chinese people rather than any other individuals or institutions that master China’s
territorial sovereignty. When it comes to issues concerning territorial sovereignty andmaritime delimitation, China will not accept any dispute settlement approach that resorts toa third party. The Chinese side urges the Philippine side to cast aside illusions, change its
course and come back to the right track of resolving disputes through negotiations andconsultations.16

83.

On 11 January 2016, the Tribunal noted that China had not submitted any comments on what
was said during the Hearing on the Merits or subsequently filed by the Philippines. The

Tribunal also conveyed a request the Registry had received from the Japanese Embassy forcopies of any relevant new documents in relation to the Hearing on the Merits. The Tribunal
invited the Parties’ views on the documents that it proposed to provide to the observer States.
The Philippines had no objection to the proposed items being provided to the observer States.
J.

FURTHER EVIDENCE, EXPERT REPORTS, AND COMMUNICATIONS FROM CHINA AND OTHERS84.

On 5 February 2016, the Tribunal sent a letter to the Parties informing them that, in reviewing
the evidentiary record and pursuing its deliberations, it had decided that it would benefit fromfurther evidence and clarifications from the Parties, and from the views of independent experts.
The Tribunal referred to Article 22(2) of the Rules of Procedure, which provides for the
Tribunal to “take all appropriate measures in order to establish the facts”; Article 22(4), which
provides that the Tribunal may “at any time during the arbitral proceedings, require the Parties
to produce documents, exhibits or other evidence”; and Article 24 which provides for the
Tribunal to appoint independent experts to report on specific issues. The Tribunal’s letter
addressed the following matters:(a)

As indicated during the Hearing on the Merits, the Tribunal remained interested inpublications and studies from China or elsewhere concerning the environmental impact ofChina’s island-building activities, 17 especially in light of statements made by public
officials and China’s State Oceanic Administration (“SOA”) indicating that such studies
had been conducted.18 The Parties were thus invited to submit comments in respect of
those materials, and China was specifically asked to indicate whether it had conducted anenvironmental impact study per Article 206 of the Convention and, if so, to provide the
Tribunal with a copy.

(b)

The Tribunal had decided to appoint an expert to provide an independent opinion onwhether the Chinese construction activities in the Spratly Islands have a detrimental
effect on the coral reef systems and the anticipated duration of such effects.

(c)

The Tribunal considered it appropriate to appoint an expert to review the available
documentary material relevant to the Philippines’ Submission No. 13 on navigationalsafety issues and to draw independent conclusions as to whether there had been aviolation of the navigational safety provisions covered by the Convention.

29

The South China Sea Arbitration
Award of 12 July 2016(d)

Recalling that it had previously sought the Parties’ comments on new documentation
about the status of Itu Aba, the Tribunal sought comments on two further documents inthe public domain that had recently come to its attention.

85.

The Tribunal proposed on 26 February 2016 to appoint Captain Gurpreet Singh Singhota, anational of the United Kingdom, as an expert on navigational safety issues and invited theParties’ comments on his qualifications, declaration of independence and draft Terms ofReference. On 29 February 2016, the Tribunal proposed to appoint Dr. Sebastian Ferse, anational of Germany, as an expert on coral reef issues and invited the Parties’ comments on his
qualifications, declaration of independence and draft Terms of Reference. Noting the size andcomplexity of the coral reef expert’s mandate, the Tribunal mentioned that it was considering
the appointment of a second expert on coral reef ecology.

86.

The Philippines reported that it approved of the proposed appointments and had no comments.
On 11 March 2016, the Philippines submitted its comments concerning additional materials
relating to (a) evidence relevant to Submissions No. 11 and 12(b) on protection of the marine
environment, and (b) materials relevant to the status of features that may generate overlapping
entitlements. Its comments were accompanied by 30 new annexes, including two new expert
reports, by Dr. Ryan T. Bailey on “Groundwater Resources Analysis of Itu Aba” and by
Dr. Peter P. Motavalli on “Soil Resources and Potential Self-Sustaining Agricultural Productionon Itu Aba.”

87.

China did not comment on the proposed appointment of either expert candidate. China did not
respond to the Tribunal’s invitation to supply information about environmental impact
assessments and did not comment on the new materials about Itu Aba.

88.

On 15 March 2016, the Tribunal invited China to comment on the new materials filed by thePhilippines and informed the Parties that it was proceeding with the appointments of CaptainSinghota and Dr. Ferse as experts under Article 24 of the Rules of Procedure.

89.

On 1 April 2016, the Tribunal sent three letters to the Parties:(a)

The first letter noted that, in furtherance of its mandate to satisfy itself that thePhilippines’ claims are well founded in fact, the Tribunal considered it appropriate tohave reference, to the greatest extent possible, to original records based on the direct
observation of the features in question, prior to them having been subjected to significant
human modification. It informed the Parties that, as the most extensive hydrographic
survey work in the South China Sea prior to 1945 was carried out by the Royal Navy of
the United Kingdom, followed closely by the Imperial Japanese Navy, the Tribunal had
30

The South China Sea Arbitration
Award of 12 July 2016

undertaken to seek records from the archives of the United Kingdom Hydrographic
Office (the “UKHO”), which also hold certain Japanese records captured during theSecond World War. The Tribunal provided documents and survey materials obtained by
the Tribunal from the UKHO archives and invited the Parties’ comments by 22 April
2016.
(b)

The second letter conveyed a request from Dr. Ferse for the Philippines to seek
clarification from the author of a 2015 report that was put into the record by thePhilippines,19 with respect to the extent of reef damage caused by dredging versus clamshell extraction, in light of some more recent reporting on the matter.20(c)

The third letter invited the Parties’ comments on four new documents that had come to
the Tribunal’s attention, namely a “Position Paper on ROC South China Sea Policy,” thecomments of the People’s Republic of China Foreign Ministry Spokesperson in responseto that Position Paper; a document published by the “Chinese (Taiwan) Society ofInternational Law” and some remarks of Mr. Ma Ying-jeou, then President of the Taiwan
Authority of China, at an international press conference “regarding Taiping [Itu Aba]
Island in Nansha Islands.”

90.

On 12 April 2016, the Tribunal informed the Parties that it intended to appoint two additional
coral reef experts to collaborate with Dr. Ferse, namely Professor Peter Mumby (a national of
the United Kingdom and Australia) and Dr. Selina Ward (a national of Australia). Theircurricula vitae, declarations of independence, and draft Terms of Reference were sent to theParties. The Philippines approved of their appointments and China did not respond.

91.

On 18 April 2016, the Tribunal sent to the Parties the expert opinion of Captain Singhota on
navigational safety issues and, in accordance with Article 24(4) of the Rules of Procedure,
invited the Parties to express any comments on the report in writing. The Philippines expressedthat it had no comments, and China did not respond.

92.

On 25 April 2016, the Philippines filed its responses to the Tribunal’s request for comments on
additional materials regarding the status of Itu Aba. While the Philippines considered that it
would have been “within its rights in requesting, and the Tribunal would be well-justified infinding, that these materials should be disregarded,” it nevertheless “recognized the exceptional

difficulties China’s non-appearance has created for the Tribunal” and chose “not to object to the
Tribunal’s consideration of Taiwan’s most recent materials should the Tribunal itself find it
appropriate to do so.” 21

The Philippines’ comments were accompanied by two revisedtranslations and 21 new annexes, including supplemental expert reports from Dr. Bailey and
Dr. Motavalli. The Philippines submitted that: (a) Taiwan’s newest materials “must be treatedwith caution,” (b) “[n]o further attempts by Taiwan to influence the Tribunal’s deliberations
should be entertained,” (c) “[i]n any event, Taiwan’s latest submissions only prove that Itu Aba
has never supported genuine, sustained human habitation or economic life of its own” as
explained in part by the “fact that Itu Aba lacks the freshwater and soil resources to do so,”(d) the historical account of China’s alleged presence in the South China Sea in “Taiwan’s
Position Paper only underscores the baseless nature of China’s claim to exclusive historicalrights to the maritime areas located within the nine-dash line,” and (e) the “PRC’s
Spokesperson’s remarks make it clear that Taiwan is alone among the littoral authorities in theSouth China Sea in claiming that Itu Aba is capable of sustaining human habitation andeconomic life of its own.”
93.

On 26 April 2016, the Philippines filed its responses to Dr. Ferse’s request for clarification on
the issue of reef damage attributable to dredging versus clam shell extraction. This included aletter and updated report from Professor John W. McManus, and a supplementary declarationfrom Professor Carpenter.

94.

On 28 April 2016, the Philippines filed its response to the UKHO materials, and submitted that“the documents and survey materials confirm the Philippines’ characterization of the relevant
features . . . as a submerged feature, a low-tide elevation, or an Article 121(3) rock.”95.

On 29 April 2016, the Tribunal sent the Parties the independent expert opinion of Dr. Ferse,
Professor Mumby, and Dr. Ward on the “Assessment of the Potential Environmental
Consequences of Construction Activities on Seven Reefs in the Spratly Islands in the South
China Sea.” Pursuant to Article 24(4) of the Rules of Procedure, the Parties had an opportunity
to express in writing their respective comments on the report. The Philippines expressed that it
had no comments, and China did not respond.

96.

On 12 May 2016, the Director-General of the Chinese Department of Treaty and Law of theChinese Ministry of Foreign Affairs, Xu Hong, gave a “Briefing on the South China Sea
Arbitration Initiated by the Philippines.” He made the following overview statement on “the21Responses of the Philippines to the Tribunal’s 1 April 2016 Request for Comments on Additional
Materials regarding the Status of Itu Aba, paras. 7-8 (25 April 2016) (hereinafter “Written Responses of
the Philippines on Itu Aba (25 April 2016)”).

32

The South China Sea Arbitration
Award of 12 July 2016

relevant policies and positions of the Chinese Government, especially from the international law
perspective,” before answering questions from the media:
China has made it clear on multiple occasions that because the Arbitral Tribunal clearly has
no jurisdiction over the present Arbitration, the decision to be made by such an institutionthat lacks the jurisdiction to do so has obviously no legal effect, and consequently there isno such thing as the recognition or implementation of the Award. Some people wonder
whether China’s position above is consistent with international law. Today, I would like toelaborate on China’s positions from the international law perspective. . . .
The first question is what is the scope of the jurisdiction of the Arbitral Tribunal.
. . . to settle international disputes by peaceful means is one of the fundamental principles ofinternational law. However, it should be noted that there are a variety of means to settle
disputes peacefully, and compulsory arbitration is merely a new type of procedure
established under the UNCLOS. Compulsory arbitration is subsidiary and complementary
to negotiation and consultation, and its application is subject to several preconditions. . . .
First, compulsory arbitration can only be applied to settle disputes concerning theinterpretation and application of the UNCLOS. If the subject matters are beyond the scopeof the UNCLOS, the disputes shall not be settled by compulsory arbitration. The issue ofterritorial sovereignty is one such case. Consequently, States shall not initiate compulsory
arbitration on disputes concerning it; and even if they do, the arbitral tribunal has no
jurisdiction over them.
Second, a State Party to the UNCLOS may declare in writing that it does not accept
compulsory arbitration with respect to disputes concerning maritime delimitation, historicbays or titles, military and law enforcement activities, etc. Such exclusions are effective toother States Parties. With respect to disputes excluded by one party, other parties to thedispute shall not initiate compulsory arbitration; and even if it does, the arbitral tribunal has
no jurisdiction over them.
Third, if parties to a dispute have agreed on other means of settlement of their own choice,no party shall unilaterally initiate compulsory arbitration; and even if it does, the arbitral
tribunal has no jurisdiction over the dispute.
Fourth, at the procedural level, parties to a dispute are obliged to first exchange views on themeans of dispute settlement. Failing to fulfill this obligation, they shall not initiatecompulsory arbitration; and even if they do, the arbitral tribunal has no jurisdiction over the
dispute.
The above four preconditions act as the “four bars” for States Parties to initiate compulsory
arbitration, and for the arbitral tribunal to establish its jurisdiction. They form a part of the
package system of dispute settlement, which shall be interpreted and appliedcomprehensively and in its entirety.
. . . If we apply the above preconditions to the arbitration unilaterally initiated by thePhilippines, it is not difficult to see that the Philippines, by initiating the arbitration, hasviolated international law in at least four aspects.
First, the essence of the subject-matter of the arbitration is territorial sovereignty over
several maritime features in the South China Sea, which is beyond the scope of the
UNCLOS. Second, even assuming some of the claims were concerned with theinterpretation and application of the UNCLOS, they would still be an integral part ofmaritime delimitation, which has been excluded by China through its 2006 Declaration andconsequently is not subject to compulsory arbitration. Third, given that China and thePhilippines have agreed to settle their disputes in the South China Sea through negotiation,
the Philippines is precluded from initiating arbitration unilaterally. Fourth, the Philippines
failed to fulfill the obligation of exchanging views with China on the means of disputesettlement.
In summary, the Philippines’ initiation of the arbitration is a typical abuse of compulsory
arbitral procedures stipulated in the UNCLOS. . . . In 2014, the Chinese Government issued

33

The South China Sea Arbitration
Award of 12 July 2016a Position Paper to elaborate, from an international law perspective, on the question why the
Tribunal lacks jurisdiction over the Arbitration. . . .
However, the Tribunal is not objective or just. On several occasions, it distorts theprovisions of the UNCLOS to embrace the claims of the Philippines. In violation of thefundamental principle that the jurisdiction shall be established based on facts and law, theArbitral Tribunal concluded that it had jurisdiction over the Philippines’ claims, which isneither convincing nor valid in international law. For such an award, China certainly has
good reasons not to recognize it. The opinions made by the Tribunal, as an institution thatmanifestly lacks jurisdiction and should not exist in the first place, are personal views of thearbitrators at best and are not legally binding, not to mention its recognition or
implementation.22

97.

On 20 May 2016, representatives from the Chinese Embassy in The Hague presented to theRegistry a letter from the new Ambassador, with the request that it be delivered to each memberof the Tribunal. The letter enclosed for reference, the “relevant position expounded on 20 May
2016 by the Spokesperson of the Ministry of Foreign Affairs of the People’s Republic of China
on the Philippines’ South China Sea arbitration.” The Ambassador reiterated that “China does
not accept or participate in the Philippines’ South China Sea arbitration. This position isconsistent and clear. My letter shall not be considered as China’s plea or participation in thePhilippines’ South China Sea arbitration.” The enclosed statement of the Foreign Ministry
Spokesperson was a response to a question as follows:
Q: The Philippines claims that it had no alternative but to initiate the arbitration because
the bilateral means has been exhausted. However, it is otherwise commented that China
and the Philippines have never engaged in any negotiation on the subject-matters thePhilippines submitted. What is China’s comment on that?
A: The Chinese Government consistently adheres to the position of settling the relevant
disputes between China and the Philippines by peaceful means through negotiation andconsultation. This is a consensus reached and repeatedly reaffirmed by the two sides, aswell as an explicit provision in the Declaration on the Conduct of Parties in the South
China Sea (DOC). Besides, in 2006, China has, pursuant to the relevant provisions in
Article 298 of the United Nations Convention on the Law of the Sea (UNCLOS), excluded
disputes concerning, among others, sea boundary delimitations, historic bays or titles,
military and law enforcement activities from the dispute settlement procedures provided in
UNCLOS. Before its unilateral initiation of the arbitration in January 2013, the Philippine
Government has not conducted any negotiation or consultation with China on the relevant
subject-matters, not to mention that it has exhausted the means of bilateral negotiation for
dispute settlement. The unilateral initiation of arbitration by the Philippines has failed tomeet the prerequisite for arbitration initiation, and cannot play a role of dispute settlement
or lead to anywhere for dispute settlement.
China always stands that, with regard to the relevant disputes between China and thePhilippines in the South China Sea, a true solution can only be sought through bilateralnegotiation and consultation. All sides should encourage the Philippines to work with

98.

The Registry forwarded the Chinese Ambassador’s letter to the members of the Tribunal and to
the Philippines.

99.

On 26 May 2016, the Tribunal informed the Parties that it considered it appropriate to consult
French material from the 1930s in order to gain a more complete picture as to the natural
conditions of the South China Sea features at that time. The Tribunal provided the Parties with
documents obtained from the Bibliothèque Nationale de France (the National Library ofFrance) and from the Archives Nationales d’Outre-Mer (the National Overseas Archives) andinvited their comments.

The Philippines commented on 3 June 2016 and supplied

supplementary materials and a further expert report from Dr. Motavalli with its response. China
was invited to, but did not, comment on the Philippines’ response.
100. The new Chinese Ambassador sent a second letter to the individual members of the Tribunal on
3 June 2016, enclosing a statement expounded by a Foreign Ministry Spokesperson in response
to a question about the status of Itu Aba. The Ambassador emphasised again that his letter does
not constitute a plea or participation in the arbitration. The enclosed statement of the Foreign
Ministry Spokesperson was the following:
Q: As reported by some foreign media, the Philippines and the arbitral tribunal areattempting to characterize Taiping Dao of China’s Nansha Islands as a “rock” other than an“island”. However, according to experts and journalists who recently visited Taiping Dao,
it is an island boasting plenty of fresh water and lush vegetation. The installations andfacilities for medical care, postal service, energy generation, and scientific research are allavailable and in good working condition. It is vibrant and lively everywhere on this island.
Do you have any comment on this?
A: China has indisputable sovereignty over the Nansha Islands and its adjacent waters,
including Taiping Dao. China has, based on the Nansha Islands as a whole, territorial sea,
exclusive economic zone and continental shelf. Over the history, Chinese fishermen haveresided on Taiping Dao for years, working and living there, carrying out fishing activities,
digging wells for fresh water, cultivating land and farming, building huts and temples, andraising livestock. The above activities are all manifestly recorded in Geng Lu Bu (Manualof Sea Routes) which was passed down from generation to generation among Chinese
fishermen, as well as in many western navigation logs before the 1930s.
The working and living practice of Chinese people on Taiping Dao fully proves that
Taiping Dao is an “island” which is completely capable of sustaining human habitation or
economic life of its own. The Philippines’ attempt to characterize Taiping Dao as a “rock”
exposed that its purpose of initiating the arbitration is to deny China's sovereignty over the23

Nansha Islands and relevant maritime rights and interests. This violates international law,and is totally unacceptable.24

101. In response to an invitation from the Tribunal, the Philippines commented on the Ambassador’s
letter and accompanying statement on 10 June 2016. The Philippines submitted that there is nobasis in the Convention for China’s assertion “based on the Nansha Islands as a whole” to aterritorial sea, exclusive economic zone and continental shelf. With respect to the Geng Lu Bu,
the Philippines observed that this “Manual of Sea Routes” is reported to be a navigation guidefor “Hainan fishermen” consistent with evidence that China’s fishermen “did no more thansojourn temporarily” at Itu Aba, and that in any event China had failed to demonstrate any
evidence by citation to specific text or supporting documentation that would constitute proof as
to the characterisation of Itu Aba.
102. On 8 June 2016, representatives from the Chinese Embassy delivered to the Registry a third
letter from the Chinese Ambassador to the individual members of the Tribunal. The letter,
which was said not to constitute a plea or participation in the arbitration, enclosed a “Statementof the Ministry of Foreign Affairs of the People’s Republic of China on Settling Disputes
Between China and the Philippines in the South China Sea through Bilateral Negotiation.” The
statement laid out jurisdictional points previously made by China in other statements, including
the Position Paper, under the following headings:
I.

It is the common agreement and commitment of China and the Philippines to settle
their relevant disputes in the South China Sea through negotiation.

...
II.

China and the Philippines have never conducted any negotiation on the subjectmatters of the arbitration initiated by the Philippines.

...
III.

The Philippines’ unilateral initiation of arbitration goes against the bilateralagreement on settling the disputes through negotiation and violates the provisions of
UNCLOS.

...
IV.

China will adhere to the position of settling the relevant disputes with thePhilippines in the South China Sea through negotiation. 25

Award of 12 July 2016

103. On 10 June 2016, a fourth letter from the Chinese Ambassador was delivered to the Registry,addressed to the individual members of the Tribunal, enclosing a statement by the Chinese
Society of International Law, entitled “The Tribunal’s Award in the ‘South China Sea
Arbitration’ Initiated by the Philippines is Null and Void.” The statement repeated many of thesame jurisdictional points that were covered in the Position Paper and dealt with in the Award
on Jurisdiction. Copies of the Chinese Ambassador’s correspondence of 8 and 10 June 2016
were forwarded to the Philippines for information.
104. During the same period that the Tribunal received the four most recent letters from the Chinese
Ambassador, the Registry received copies or was made aware of various unsolicited statements
and commentaries from Chinese associations and organisations pertaining to issues covered in
the Award on Jurisdiction. These statements, however, were not provided to the Tribunal by the
Chinese Government or any Party to the Convention. The statements were concerned withmatters of jurisdiction already decided by the Tribunal and did not offer to assist the Tribunal on
issues in dispute in the present phase of the proceedings.
105. On 23 June 2016, the Embassy of Malaysia in the Netherlands sent to the Tribunal two Notes
Verbales, drawing attention to an issue with certain maps contained in the Award on
Jurisdiction (which had been extracted, for illustrative purposes, from the Philippines’
Memorial), and requesting that the Tribunal show due regard to the rights of Malaysia(“Malaysia’s Communication”). The Malaysian Embassy emphasised that it was not seeking
to intervene in the proceedings. The Tribunal sent copies of Malaysia’s Communication to theParties and requested any comments by 28 June 2016. The Philippines commented on 28 June
2016. With respect to the maps, the Philippines noted that it had presented the maps in such a
way as to preserve its own claim but would leave the issue to the Tribunal’s discretion. With
respect to Malaysia’s assertions that issues in dispute may directly or indirectly affect its rights
and interests, the Philippines noted that this question had already been dealt with by the
Tribunal. The Philippines considered Malaysia’s Communication therefore to be “without
merit” and also pointed out that it was “untimely”, in light of the fact that Malaysia had been an
observer since 10 June 2015 and until now made no effort to raise its concerns. China did notcomment on Malaysia’s Communication.

On 29 June 2016, the Tribunal forwarded thePhilippines’ comments to China and acknowledged to Malaysia that it had received and takennote of its Communication.26
26

The Tribunal recalls with respect to the maps published at pp. 3 and 9 of the Award on Jurisdiction that it
had stated at p. iv of the Award on Jurisdiction: “The figures in this Award have been taken from thePhilippines’ Memorial and are included for illustrative purposes only. Their use in this Award is not anindication that the Tribunal endorses the figures or adopts any associated arguments from thePhilippines.” The Tribunal notes that the maps contained in the present Award are likewise for

NOTIFICATION, PUBLICATION, AND TRANSLATION OF AWARD

106. By advance notification that was published on the PCA’s website and sent directly to theParties, observer States and interested media, the Tribunal advised on 29 June 2016, that it
would be issuing this Award on 12 July 2016.
107. On 1 July 2016, the Philippines informed the Tribunal, in accordance with Article 4(2) of theRules of Procedure, that as of 30 June 2016 Mr. Jose C. Calida had been appointed Solicitor
General of the Philippines and had also been appointed to serve as Agent in the arbitration. The
Philippines requested that future correspondence be directed to him and Attorney Anne Marie L.
Corominas. A copy of the Philippines’ letter was forwarded to China for information.
108. The Tribunal has authorised the Registry to publish a press release in English (official version),
French, and Chinese at the same time as the issuance of the present Award.
109. In accordance with Article 15(2) of the Rules of Procedure, the Tribunal has instructed that, indue course, the Registry shall arrange for the translation of the Award on Jurisdiction and thepresent Award into Chinese, to be made available to the public. The English version of theAwards, however, shall remain the only authentic version.

DEPOSITS FOR COSTS OF THE ARBITRATION

110. Article 33 of the Rules of Procedure states that the PCA may from time to time request theParties to deposit equal amounts as advances for the costs of the arbitration. Should either Party
fail to make the requested deposit within 45 days, the Tribunal may so inform the Parties inorder that one of them may make the payment. The Parties have been requested to makepayments toward the deposit on three occasions. While the Philippines paid its share of thedeposit within the time limit granted on each occasion, China has made no payments toward thedeposit. Having been informed of China’s failure to pay, the Philippines paid China’s share of
the deposit.
110. The deposit has covered the fees and expenses of members of the Tribunal, Registry, andexperts appointed to assist the Tribunal, as well as all other expenses including for hearings andmeetings, information technology support, catering, court reporters, deposit administration,archiving, translations, couriers, communications, correspondence, and publishing of theAwards. Article 7 of Annex VII to the Convention provides that “[u]nless the arbitral tribunal

Jurisdiction does not reflect any decision taken by the Tribunal with respect to the status of any land
territory or any decision taken by the Tribunal with respect to any non-party to the present arbitration.

111. In accordance with Article 33(4) of the Rules of Procedure, the Registry will “render an
accounting to the Parties of the deposits received and return any unexpended balance to theParties” after the issuance of this Award.

PRELIMINARY MATTERSA.

THE LEGAL AND PRACTICAL CONSEQUENCES OF CHINA’S NON-PARTICIPATION

116. As is evident from the procedural history recounted in Chapter II, China has consistently
rejected the Philippines’ recourse to arbitration and has adhered to a position of non-acceptanceand non-participation in the proceedings. China did not participate in the constitution of the
Tribunal, it did not submit a Counter-Memorial in response to the Philippines’ Memorial, it did
not attend the Hearings on Jurisdiction or on the Merits, it did not reply to the Tribunal’s
invitations to comment on specific issues of substance or procedure, and it has not advanced anyof the funds requested by the Tribunal toward the costs of the arbitration. Throughout theproceedings, China has rejected and returned correspondence from the Tribunal sent by theRegistry, reiterating on each occasion “that it does not accept the arbitration initiated by thePhilippines.”
117. The Convention, however, expressly acknowledges the possibility of non-participation by oneof the parties to a dispute and confirms that such non-participation does not constitute a bar tothe proceedings. Article 9 of Annex VII provides:
Article 9
Default of Appearance
If one of the parties to the dispute does not appear before the arbitral tribunal or fails to
defend its case, the other party may request the tribunal to continue the proceedings and to
make its award. Absence of a party or failure of a party to defend its case shall notconstitute a bar to the proceedings. Before making its award, the arbitral tribunal mustsatisfy itself not only that it has jurisdiction over the dispute but also that the claim is wellfounded in fact and law.

118. Pursuant to Article 9, the Philippines expressly requested that these proceedings continue. 31
The Tribunal has continued the proceedings, confirming that despite its non-appearance, China
remains a party to the arbitration, with the ensuing rights and obligations, including that it will
be bound under international law by any decision of the Tribunal.32

Convention, art. 296(1) (providing that any decision rendered by a tribunal having jurisdiction under

1.

Steps Taken to Ensure Procedural Fairness to Both Parties

119. Article 9 of Annex VII seeks to balance the risks of prejudice that could be suffered by either
party in a situation of non-participation. First, it protects the participating party by ensuring thatproceedings will not be frustrated by the decision of the other party not to participate. Second,
it protects the rights of the non-participating party by ensuring that a tribunal will not simply
accept the evidence and claims of the participating party by default.33
120. The respective procedural rights of the parties are further articulated in Article 5 of Annex VII,
which provides that “the arbitral tribunal shall determine its own procedure, assuring to eachparty a full opportunity to be heard and to present its case.”34
121. The Tribunal has taken a number of measures to safeguard the procedural rights of China. For
example, it has:(a)ensured that all communications and materials in the arbitration have been promptly
delivered, both electronically and physically, to the Ambassador of China to the Kingdomof the Netherlands in The Hague;(b)granted China adequate and equal time to submit written responses to the pleadings
submitted by the Philippines;(c)invited China (as with the Philippines) to comment on procedural steps taken throughout
the proceedings;(d)provided China (as with the Philippines) with adequate notice of hearings and multiple
opportunities to comment on the setting and scheduling of both the Hearing on
Jurisdiction and Hearing on the Merits, as described at paragraphs 47 to 53, 54 to 59
and 61 to 76 above;(e)

promptly provided to China (as with the Philippines) copies of transcripts of the Hearingon Jurisdiction and Hearing on the Merits;(f)invited China to comment on anything said during the Hearing on Jurisdiction andHearing on the Merits;

33
34

Award on Jurisdiction, para. 115.
This duty is mirrored in the Rules of Procedure, art. 10(1) (“the Arbitral Tribunal may conduct thearbitration in such manner as it considers appropriate, provided that the Parties are treated with equality
and that at any stage of the proceedings each Party is given a full opportunity to be heard and to present
its case.”) and art. 1 (providing for modification or additions to the Rules of Procedure, or novel questionsof procedure, to be addressed “after seeking the views of the Parties.”).

46

The South China Sea Arbitration
Award of 12 July 2016(g)invited China (as with the Philippines) to comment on the proposed candidates and termsof reference for independent experts appointed by the Tribunal;(h)invited China (as with the Philippines) to comment on certain materials in the publicdomain, but not already in the case record;(i)made the Registry staff available to Chinese Embassy personnel to answer informal
questions of an administrative or procedural nature;(j)

had the Registry convey written communications from the Chinese Embassy to theindividual members of the Tribunal; and(k)reiterated that it remains open to China to participate in the proceedings at any stage.

122. The Tribunal has also taken measures to safeguard the Philippines’ procedural rights. As notedby the International Tribunal for the Law of the Sea in Arctic Sunrise, a participating party“should not be put at a disadvantage because of the non-appearance of the [non-participating
party] in the proceedings.”35
123. One possible disadvantage of non-participation is delay.

While ensuring equality ofopportunity, the Tribunal has also complied with the obligation in Article 10 of the Rules ofProcedure to “conduct the proceedings so as to avoid unnecessary delay and expense and toprovide a fair and efficient process for resolving the Parties’ dispute.”
124. A second possible disadvantage about which the Philippines expressed concern was that
China’s non-appearance might deprive it of “an opportunity to address any specific issues that
the Arbitral Tribunal considers not to have been canvassed, or to have been canvassed
inadequately.”36 The Tribunal has taken various steps to ensure both Parties the opportunity toaddress specific issues of concern to the Tribunal’s decision-making. For example, the Tribunal
introduced the following process into Article 25(2) of its Rules of Procedure:In the event that a Party does not appear before the Arbitral Tribunal or fails to defend its
case, the Arbitral Tribunal shall invite written arguments from the appearing Party on, orpose questions regarding, specific issues which the Arbitral Tribunal considers have notbeen canvassed, or have been inadequately canvassed, in the pleadings submitted by theappearing Party. The appearing Party shall make a supplemental written submission in
relation to the matters identified by the Arbitral Tribunal within three months of the
Arbitral Tribunal’s invitation. The supplemental submission of the appearing Party shall be
communicated to the non-appearing Party for its comments which shall be submitted within
three months of the communication of the supplemental submission. The Arbitral Tribunal
may take whatever other steps it may consider necessary, within the scope of its powers

47

Award of 12 July 2016

under the Convention, its Annex VII, and these Rules, to afford to each of the Parties a fullopportunity to present its case. 37

125. The Tribunal implemented the above procedure by issuing a Request for Further Written
Argument on 16 December 2014, containing 26 questions pertaining to jurisdiction and themerits.

Further, on 23 June 2015, in advance of the Hearing on Jurisdiction, and on

23 November 2015, in advance of the Hearing on the Merits, the Tribunal sent to the Parties
lists of specific issues which it wished to be addressed. During both hearings, following thefirst round of arguments, the Tribunal circulated lists of questions to be addressed during thesecond round.
126. A third perceived disadvantage that the participating party may face as a result of
non-participation is being put in the “position of having to guess” what the non-participating
party’s arguments might be and to “formulate arguments for both States.”38 The Philippines
suggested that the Tribunal could discern China’s position on the issues raised by thePhilippines’ Submissions by consulting communications from China’s officials, statements of
those associated with the Government of China, and academic literature by individuals closely
associated with Chinese authorities.39 The Tribunal has done so, cognisant of the practice ofinternational courts and tribunals of taking notice of public statements or informal
communications made by non-appearing Parties.40
127. Concerns about the Philippines “having to guess what China’s arguments might be” were tosome extent alleviated, at least with respect to jurisdiction, by China’s decision to make publicits Position Paper in December 2014. The Position Paper was followed by two letters from theformer Chinese Ambassador, addressed to the members of the Tribunal, and four more-recent
letters from the current Chinese Ambassador. The latter directed the Tribunal’s attention tostatements of the Chinese Ministry of Foreign Affairs Spokespersons and other publicstatements and materials. Indeed, the Tribunal has taken note of the regular press briefings of
the Chinese Ministry of Foreign Affairs, which frequently touch on issues before the Tribunal,and occasionally contain statements exclusively dedicated to aspects of the arbitration. On the

48

The South China Sea Arbitration
Award of 12 July 2016very question of China’s non-participation, the Director-General of the Department of Treaty
and Law at the Chinese Ministry of Foreign Affairs gave the following remarks in response toquestions about why China did not participate and whether, having renounced the opportunity toappear before the Tribunal to contest jurisdiction, China should “bear the consequences”:
First, not accepting or participating in arbitral proceedings is a right enjoyed by a sovereign
State. That is fully in conformity with international law. And certainly, China is not thefirst State to do so. For such a proceeding that is deliberately provocative, China hasneither the obligation nor the necessity to accept or participate in it. The Philippines’
initiation of the Arbitration lacks basic grounds in international law. Such an act canneither generate any validity in international law, nor create any obligation on China.
Second, by not accepting or participating in the arbitral proceedings, we aim to safeguard
the solemnity and integrity of international law, including the UNCLOS, to oppose theabuse of the compulsory arbitration procedures, and to fulfill our commitments with thePhilippines to settle relevant disputes through negotiations. The commitments werebreached by the Philippines, but China remains committed to them.
Third, the actual objective of the Philippines to initiate the Arbitration and that of someother States to fuel the fire are not to genuinely resolve disputes. The Philippines was fully
aware that the Arbitral Tribunal has no jurisdiction over disputes concerning territorial
sovereignty and maritime delimitation between the two States; it was fully aware that it wasabsolutely not possible that China would accept the compulsory arbitration; and it was also
fully aware that such a means would not help resolve the problem. With full awareness of
the above, the Philippines still decided to abuse the provisions of the UNCLOS byunilaterally initiating and then pushing forward the arbitral proceedings. Some other States,
who were making every effort to echo it, apparently have their ulterior motives. For such agame, there is no point for China to humor it.
Fourth, whether or not China accepts and participates in the arbitral proceedings, theArbitral Tribunal has the obligation under international law to establish that it does havejurisdiction over the disputes. But from what we have seen, it apparently has failed tofulfill the obligation and the ruling would certainly be invalid. So there is no such thing ofChina’s taking the consequence of the arbitration. If anything, it is the Philippines thatshould bear all the consequences of abusing the UNCLOS.41

128. It is in relation to the fourth point above, “the Tribunal’s obligation under international law toestablish that it does have jurisdiction over the disputes” to which the Tribunal next turns.
2.

Steps Taken by the Tribunal to Satisfy Itself that It Has Jurisdiction and that the
Claim is Well Founded in Fact and Law

129. China’s non-participation imposes a special responsibility on the Tribunal. There is no systemof default judgment under the Convention. As will be apparent in the course of this Award, theTribunal does not simply adopt the Philippines’ arguments or accept its assertions untested.
Rather, under the terms of Article 9 of Annex VII, the Tribunal “must satisfy itself not only thatit has jurisdiction over the dispute but also that the claim is well founded in fact and law” before
making any award.

The South China Sea Arbitration
Award of 12 July 2016

130. The Tribunal has actively sought to satisfy itself as to whether it has jurisdiction over the
dispute. Following China’s decision not to file a Counter-Memorial, the Tribunal requested thePhilippines under Article 25 of the Rules of Procedure to provide further written argument on
certain jurisdictional questions and posed questions to the Philippines both prior to and during
the Hearing on Jurisdiction. China’s Position Paper in December 2014 expounded three main
reasons why it considers that the Tribunal “does not have jurisdiction over this case.”42 The
Tribunal decided to treat the Position Paper and certain communications from China as
constituting, in effect, a plea concerning jurisdiction, which under the Rules of Procedure meantconducting a hearing and issuing a preliminary ruling dedicated to jurisdiction.43 However, inline with its duty to satisfy itself that it has jurisdiction, the Tribunal did not limit the hearing to
the three issues raised by China. It also considered, and invited the Parties to address, otherpossible jurisdictional questions. These procedures led to the Tribunal’s Award on Jurisdiction,issued on 29 October 2015 (a summary of which appears at paragraphs 145 to 164 below).
131. With respect to the duty to satisfy itself that the Philippines’ claims are well founded in fact andlaw, the Tribunal notes that Article 9 of Annex VII does not operate to change the burden of
proof or to raise or lower the standard of proof normally expected of a party to make out its
claims or defences.44 However, as a practical matter, Article 9 has led the Tribunal to take steps
to test the evidence provided by the Philippines and to augment the record by seeking additional
evidence, expert input, and Party submissions relevant to questions arising in this merits phase,including as to the status of features in the South China Sea, the allegations concerning
violations of maritime safety obligations, and claims about damage to the marine environment.
These steps are described below.
132. First, pursuant to the procedure established in Article 25 of the Rules of Procedure, in the
Tribunal’s Request for Further Written Argument of 16 December 2014, the Tribunal noted thePhilippines’ argument that “none of the features in the Spratlys—not even the largest among
them—is capable of generating entitlement to an EEZ or a continental shelf.”45 The Tribunal
invited the Philippines to “provide additional historical and anthropological information, as well
as detailed geographic and hydrographic information regarding” Itu Aba, Thitu, and West
York.”46 The Tribunal also invited the Philippines to provide written argument on the status of

The Tribunal’s Request for Further Written Argument by the Philippines Pursuant to Article 25(2) of theRules of Procedure, Request No. 20, annexed to Procedural Order No. 3 (16 December 2014) (hereinafter“Request for Further Written Argument”).

50The South China Sea Arbitration
Award of 12 July 2016any maritime feature claimed by China—“whether or not occupied by China”—that could
potentially give rise to an entitlement to an exclusive economic zone or continental shelfextending to any of Mischief Reef, Second Thomas Shoal, Subi Reef, Scarborough Shoal,
Reed Bank, or the areas designated as Philippine oil blocks “Area 3” and “Area 4”. In so doing,
the Philippines was invited to provide “historical and anthropological information, as well as
detailed geographic and hydrographic information” regarding the following features: Spratly
Island, North-East Cay (North Danger Reef); South-West Cay (North Danger Reef); Nanshan
Island; Sand Cay; Loaita Island; Swallow Reef; Amboyna Cay; Flat Island; Lankiam Cay; Great
Discovery Reef; Tizard Bank reefs; and Union Bank reefs.47 In response to this request, thePhilippines submitted with its Supplemental Written Submission an atlas and an expert reportby Professor Clive Schofield, Professor J.R.V. Prescott, and Mr. Robert van der Poll entitled“An Appraisal of the Geographical Characteristics and Status of Certain Insular Feature in theSouth China Sea” (the “Schofield Report”). The atlas provided for each feature: a geographic
and hydrographic description, a satellite image, photographs, excerpts from various sailingdirections and nautical charts, and a summation of the pertinent geographic and hydrographic
information by geographer Dr. Robert W. Smith.48
133. Second, in accordance with Article 24 of the Rules of Procedure, and after seeking the views of
the Parties, the Tribunal retained an independent technical expert—Mr. Grant Boyes—to assist
it in “reviewing and analysing geographic and hydrographic information, photographs, satellite
imagery and other technical data in order to enable the Arbitral Tribunal to assess the status (asa submerged feature, low-tide elevation, or island)” of the features named in the Philippines’
Submissions or any other such feature determined to be relevant during the course of thereference. While the appointment of hydrographic experts is common practice in Annex VII
arbitrations,49 in light of China’s non-participation, Mr. Boyes was also tasked with assisting witha “critical assessment of relevant expert advice and opinions submitted by the Philippines.”50

134. Third, the Tribunal posed to Professor Schofield a series of written and oral questions during the
Hearing on the Merits, about his testimony, his earlier writings, and specific points in the
Schofield Report.51
135. Fourth, the Tribunal similarly posed written and oral questions to Professor Kent Carpenter,
who submitted two expert reports for the Philippines about the environmental consequences ofChina’s conduct in the South China Sea.52 Professor Carpenter’s second report was submitted,
inter alia, to adequately address the issues identified by the Tribunal in its “Annex of Issues”
circulated in advance of the Hearing on the Merits.53
136. Fifth, in light of China’s non-participation, the Tribunal decided to appoint coral reef ecology
experts to provide their independent opinion on the impact of Chinese construction activities on
the coral reef systems in the Spratly Islands.

A team composed of Dr. Sebastian Ferse,

Professor Peter Mumby, and Dr. Selina Ward prepared a report (the “Ferse Report”), on which
both sides were invited to comment. In the course of preparing the report, some follow-up
questions were put to the Philippines about sources relied on in the Carpenter Report, a process
through which the Tribunal gained yet further information.54
137. Sixth, the Tribunal has made efforts to understand China’s stance on environmental issues,
including having (a) asked the Philippines and Professor Carpenter to identify any statements
made by Chinese Government officials that suggest China had taken into account issues of
ecological preservation and followed environmental protection standards in connection with its
construction work;55 (b) presented to the Parties for their comment a number of official Chinesestatements and reports from Chinese State-sponsored scientific institutes concerning theecological impact of the construction work;56 (c) specifically and directly asked China whether

statements to the effect that “[a]s owners of the Nansha Islands, China cares about protecting theecological environment of relevant islands, reefs and waters more than any other country,
organization or people of the world” and that “[b]ased on thorough studies and scientific proof,
China adopts dynamic protection measures along the whole process so as to combine
construction with ecological environmental protection and realize sustainable development ofislands and reefs.”58 As noted below in Chapter VII.D, neither the Tribunal nor its experts,
however, have managed to retrieve copies of such studies.
138. Seventh, in relation to the Philippines’ Submission No. 13, alleging dangerous manoeuvring by
Chinese law enforcement vessels in breach of the Convention’s maritime safety obligations, theTribunal considered it appropriate to appoint an expert to review the available documentarymaterial and draw independent conclusions. In accordance with Article 24 of the Rules ofProcedure and having consulted the Parties, the Tribunal commissioned a report by Captain
Gurpreet Singhota (the “Singhota Report”).
139. Eighth, in accordance with Article 22 of the Rules of Procedure, which provides that the
Tribunal may “take all appropriate measures in order to establish the facts,” and Article 25,
which states that the Tribunal “may take whatever other steps it may consider necessary . . . toafford to each of the Parties a full opportunity to present its case,” the Tribunal has on several
occasions invited the Parties to comment on various sources concerning the prevailingconditions on features in the South China Sea, including some materials in the public domainemanating from the Taiwan Authority of China. 59

The Philippines has responded withcomments both during the hearings and in written submissions after the hearings. 60 On
11 March 2016, the Philippines submitted written comments, accompanied by two new expert

Award of 12 July 2016an invitation to comment further on additional Taiwanese materials. While the Philippines
considered that it would have been “within its rights in requesting, and the Tribunal would bewell-justified in finding, that these materials should be disregarded,” it nevertheless“recognize[d] the exceptional difficulties China’s non-appearance has created for the Tribunal”
and chose “not to object to the Tribunal’s consideration of Taiwan’s most recent materials.” 62
Accordingly, the Philippines provided comments, translations and exhibits, and supplementary
expert reports. China did not submit comments to the Tribunal in response to these materials,
though its public statements on relevant questions have been noted.63
140. Ninth, the Tribunal sought the Parties’ views on records obtained from the UKHO. Prior to the
Hearing on the Merits, the Tribunal had requested the Philippines to confirm “whether it has
sought and been able to obtain copies of hydrographic survey plans (fair charts), relating inparticular to those surveys undertaken by the United Kingdom in the Nineteenth Century and by
Japan in the period leading up to the Second World War.”64 The Philippines replied that it had
not and explained that it considered it unnecessary to do so.65 On 1 April 2016, the Tribunal
informed the Parties that it considered it appropriate to have reference, to the greatest extent
possible, to original records based on the direct observation of the features in question, prior tothem having been subjected to significant human modification.

As the most extensivehydrographic survey work in the South China Sea prior to 1945 was carried out by the Royal
Navy of the United Kingdom, followed closely by the Imperial Japanese Navy, the Tribunal
advised that it had undertaken to seek records from the archives of the UKHO, which also holdcertain Japanese records captured during the Second World War. The Tribunal provided copies
of records to the Parties and invited their comments, which the Philippines provided on 28 April
2016.
141. Tenth, the Tribunal also considered it appropriate to consult French material from the 1930s inlight of France’s occupation of the Spratly Islands announced in 193366 and in order to gain amore complete picture as to the natural conditions of the South China Sea features.
Accordingly, the Tribunal sought records from the online database of the Bibliothèque
Nationale de France and from the Archives Nationales d’Outre-Mer. On 26 May 2016, the

Award of 12 July 2016

Tribunal provided the Parties with the most pertinent documents obtained from those sources
and allowed them an opportunity to comment.

The Philippines sent its comments, with

supplementary materials, on 3 June 2016.
142. As explained in the Tribunal’s communications to the Parties, the Tribunal considered historical
records concerning conditions on features in the Spratly Islands, prior to them having been
subjected to significant human modification, to be more relevant than evidence of the situation
currently prevailing, which reflects the efforts of the various littoral States to improve thehabitability of features under their control.

Accordingly, although the Tribunal has fully

considered the contemporary evidence provided by the Philippines, as well as certain materials
made public by the Taiwan Authority of China, the Tribunal has not itself sought additional
materials on contemporary conditions on any feature in the Spratlys. The Tribunal has, for thesame reason, not sought to take advantage of the Taiwan Authority of China’s public offer toarrange a site visit to Itu Aba. In this respect the Tribunal notes that China, through its
Ambassador’s letter of 6 February 2015, objected strongly to the possibility of any site visit to
the South China Sea by the Tribunal.67
3.

Conclusion on the Legal and Practical Consequences of China’s Non-Participation

143. For reasons set out above, despite its non-participation in the proceedings, China is a Party to
the arbitration and is bound under international law by any awards rendered by the Tribunal.
144. In line with its duties under Annex VII to the Convention, in the circumstances of China’s
non-participation, the Tribunal has taken steps to ensure procedural fairness to both Parties
without compromising the efficiency of the proceedings. The Tribunal has also taken steps toascertain China’s position on the issues for decision, based on statements made by Chinese
officials publicly and in communications to the members of the Tribunal. In addition to its
thorough review of the materials placed before it by the Philippines, the Tribunal has also taken
steps to satisfy itself of its jurisdiction and the legal and factual foundations of the Philippines’
claims through obtaining independent expert input, reviewing other materials in the publicdomain, and inviting further comments from the Parties on those sources.

SUMMARY OF THE TRIBUNAL’S AWARD ON JURISDICTION

145. Pursuant to Article 288(4) of the Convention, “[i]n the event of a dispute as to whether a court
or tribunal has jurisdiction, the matter shall be settled by decision of that court or tribunal.” As
set out above, where a Party does not appear before the Tribunal, Article 9 of Annex VII to theConvention requires that “the arbitral tribunal must satisfy itself not only that it has jurisdiction
over the dispute but also that the claim is well founded in fact and law.” Additionally, the Rulesof Procedure adopted by the Tribunal provide at Article 20(3) as follows:
The Arbitral Tribunal shall rule on any plea concerning its jurisdiction as a preliminary
question, unless the Arbitral Tribunal determines, after seeking the views of the Parties, thatthe objection to its jurisdiction does not possess an exclusively preliminary character, inwhich case it shall rule on such a plea in conjunction with the merits. 68

146. China’s Position Paper was said by the Chinese Ambassador to have “comprehensively
explain[ed] why the Arbitral Tribunal . . . manifestly has no jurisdiction over the case.”69 In its
Procedural Order No. 4 of 21 April 2015, the Tribunal recalled the practice of international
courts and tribunals in interstate disputes of (a) taking note of public statements or informal
communications made by non-appearing Parties, (b) treating such statements andcommunications as equivalent to or as constituting preliminary objections, and (c) bifurcatingproceedings to address some or all of such objections as preliminary questions.70 The Tribunal
considered that:the communications by China, including notably its Position Paper of 7 December 2015
and the Letter of 6 February 2015 from the Ambassador of the People’s Republic of China
to the Netherlands, effectively constitute a plea concerning this Arbitral Tribunal’s
jurisdiction for the purposes of Article 20 of the Rules of Procedure and will be treated assuch for the purposes of this arbitration.71

147. Accordingly, the Tribunal decided:in light of the circumstances and its duty to “assure to each Party a full opportunity to beheard and to present its case,” it is appropriate to bifurcate the proceedings and to convene a

hearing to consider the matter of the Arbitral Tribunal’s jurisdiction and, as necessary, theadmissibility of the Philippines’ submissions.”72

148. The Tribunal also noted that it would not limit itself to hearing only the questions raised in
China’s Position Paper.73 The Tribunal accordingly convened the Hearing on Jurisdiction in
The Hague on 7, 8, and 13 July 2015 and issued its Award on Jurisdiction on 29 October 2015.
The principal findings of that decision are recalled herein.
1.

Preliminary Matters149. In its Award on Jurisdiction, the Tribunal noted that “both the Philippines and China are parties
to the Convention”74 and that the provisions for the settlement of disputes, including througharbitration, form an integral part of the Convention.75 Although the Convention specifies certain
limitations and exceptions to the subject matter of the disputes that may be submitted tocompulsory settlement, it does not permit other reservations, and a State may not except itself
generally from the Convention’s mechanism for the resolution of disputes.76
150. The Tribunal also noted China’s non-participation and held that this fact does not deprive the
Tribunal of jurisdiction. In this respect, the Tribunal recalled the provisions of Article 9 ofAnnex VII to the Convention.
151. Although China did not participate in the constitution of the Tribunal, the Tribunal held that it
had been properly constituted pursuant to the provisions of Annex VII to the Convention.77 The
Tribunal detailed the steps it had taken to satisfy itself regarding its jurisdiction, including
through questions posed to the Philippines and through the Hearing on Jurisdiction in
July 2015.78 The Tribunal also recalled the steps it had taken to safeguard the procedural rights
of both Parties in the circumstances of China’s non-participation.79
152. Finally, the Tribunal considered the argument set out in China’s Position Paper that thePhilippines’ unilateral resort to arbitration constituted an abuse of the dispute settlement

that are facially unfounded, it was more appropriate to consider China’s concerns about the
Tribunal’s jurisdiction as a preliminary objection.81 The Tribunal also noted that “the mere actof unilaterally initiating an arbitration under Part XV in itself cannot constitute an abuse” of theConvention.82
2.

Existence of a Dispute concerning Interpretation and Application of the Convention

153. The Tribunal next considered whether there is a dispute between the Parties concerning theinterpretation or application of the Convention, which is the basis for the dispute settlement
mechanisms of the Convention.83 In so doing, the Tribunal considered two objections set out in
China’s Position Paper: first, that the Parties’ dispute is actually about sovereignty over theislands of the South China Sea and therefore not a matter concerning the Convention, andsecond, that the Parties’ dispute is actually about the delimitation of the maritime boundary
between them and therefore excluded from dispute settlement by an exception set out in theConvention that States may activate by declaration. China activated the exception for disputes
concerning sea boundary delimitations when it made a declaration in 2006.
154. With respect to the former objection, the Tribunal noted that there is a dispute between theParties regarding sovereignty over islands, but held that the matters submitted to arbitration by
the Philippines do not concern sovereignty.84 The Tribunal considered it to be expected that thePhilippines and China would have disputes regarding multiple subjects, but emphasised that the
Tribunal did not accept that “it follows from the existence of a dispute over sovereignty thatsovereignty is also the appropriate characterisation of the claims the Philippines has submitted
in these proceedings.”85 The Tribunal also emphasised that “[t]he Philippines has not asked the
Tribunal to rule on sovereignty and, indeed, has expressly and repeatedly requested that the
Tribunal refrain from so doing.”86 The Tribunal emphasised that it did “not see that any of thePhilippines’ Submissions require an implicit determination of sovereignty.” 87 Finally, the80Award on Jurisdiction, paras. 124-129.

Tribunal observed that it was “fully conscious of the limits on the claims submitted to it and, tothe extent that it reaches the merits of any of the Philippines’ Submissions, intends to ensurethat its decision neither advances nor detracts from either Party’s claims to land sovereignty in
the South China Sea.”88
155. With respect to the latter objection, the Tribunal noted that a dispute concerning whether a Statepossesses an entitlement to a maritime zone is a distinct matter from the delimitation ofmaritime zones in an area in which they overlap. 89 While a wide variety of issues arecommonly considered in the course of delimiting a maritime boundary, it does not follow that adispute over each of these issues is necessarily a dispute over boundary delimitation. In
particular, the Tribunal emphasised that:
A maritime boundary may be delimited only between States with opposite or adjacentcoasts and overlapping entitlements. In contrast, a dispute over claimed entitlements may
exist even without overlap, where—for instance—a State claims maritime zones in an area
understood by other States to form part of the high seas or the Area for the purposes of theConvention.90

Accordingly, the Tribunal held that the claims presented by the Philippines do not concern sea
boundary delimitation and are not, therefore, subject to the exception to the dispute settlement
provisions of the Convention. 91 The Tribunal also emphasised that the Philippines had not
asked it to delimit any boundary.92
156. Turning to the matters raised in the Philippines’ Submissions, the Tribunal reviewed the record
to determine whether disputes existed between the Parties at the time the Philippines
commenced this arbitration and whether such disputes concerned the interpretation andapplication of the Convention.93 In so doing, the Tribunal noted that it was necessary to addresssome ambiguity regarding China’s position on the matters before it and recalled that theexistence of a dispute may be inferred from the conduct of a State, or from silence, and is amatter to be determined objectively.94 The Tribunal considered that each of the Philippines’
claims reflected a dispute concerning the Convention95 and noted in particular that a dispute

concerning the interaction between the Convention and other rights (including any Chinese
historic rights) is a dispute concerning the Convention.96
3.

Involvement of Indispensable Third Parties

157. Having identified the disputes presented by the Philippines’ Submissions, the Tribunal
considered whether the absence from this arbitration of other States, such as Viet Nam, thathave claims to the islands of the South China Sea would be a bar to the Tribunal’s jurisdiction.97
The Tribunal noted that this arbitration differs from past cases in which a court or tribunal has
found the involvement of a third party to be indispensable.98 The Tribunal recalled that “thedetermination of the nature of and entitlements generated by the maritime features in the South
China Sea does not require a decision on issues of territorial sovereignty” and held accordinglythat “[t]he legal rights and obligations of Viet Nam therefore do not need to be determined as aprerequisite to the determination of the merits of the case.”99 The Tribunal also recalled that, in
December 2014, Viet Nam submitted a “Statement of the Ministry of Foreign Affairs ofViet Nam” for the Tribunal’s attention, in which Viet Nam asserted that it has “no doubt that the
Tribunal has jurisdiction in these proceedings.”100
4.

Preconditions to Jurisdiction

158. The Tribunal then considered the preconditions to jurisdiction set out in the Convention.
Although the dispute settlement mechanism of the Convention provides for compulsory
settlement, including through arbitration, it also permits parties to agree on the settlement ofdisputes through alternative means of their own choosing.

Articles 281 and 282 of theConvention may prevent a State from making use of the mechanisms under the Convention if
they have already agreed to another means of dispute resolution. Article 283 also requires theParties to exchange views regarding the settlement of their dispute before beginning arbitration.
159. The Tribunal considered the applicability of Articles 281 and 282 to the following instruments
to determine whether the Parties had agreed to another means of dispute settlement: (a) the
2002 China–ASEAN Declaration on the Conduct of Parties in the South China Sea (the“DOC”), (b) a series of joint statements issued by the Philippines and China referring to the96

resolution of disputes through negotiations, (c) the Treaty of Amity and Cooperation inSoutheast Asia, and (d) the Convention on Biological Diversity (the “CBD”). The Tribunal
held that the DOC is a political agreement and “was not intended to be a legally binding
agreement with respect to dispute resolution,” 101 does not provide a mechanism for binding
settlement,102 and does not exclude other means of settlement.103 The Tribunal reached the sameconclusion with respect to the joint statements identified in China’s Position Paper. 104 With
respect to the Treaty of Amity and Cooperation in Southeast Asia and the CBD, the Tribunal
noted that both are legally binding agreements with their own procedures for disputes, but thatneither provides a binding mechanism and neither excludes other procedures.105 Additionally,
the Tribunal noted that although there is overlap between the environmental provisions of the
UN Convention on the Law of the Sea and the CBD, this does not mean that a disputeconcerning one instrument is necessarily a dispute concerning the other or that theenvironmental claims brought by the Philippines should instead be considered under theframework of the CBD.106 Accordingly, the Tribunal concluded that none of these instruments
prevent the Philippines from bringing its claims to arbitration.
160. With respect to the exchange of views on the settlement of the dispute, the Tribunal held that
Article 283 requires parties to exchange views on the means of settling their dispute, not thesubstance of that dispute.107 The Tribunal held that this requirement was met in the record of
diplomatic communications between the Philippines and China, in which the Philippines
expressed a clear preference for multilateral negotiations involving the other States surrounding
the South China Sea while China insisted that only bilateral talks could be considered.108 The
Tribunal also considered whether, independently of Article 283, the Philippines was under anobligation to pursue negotiations before resorting to arbitration.109 In this respect, the Tribunal
held that the Philippines had sought to negotiate with China 110 and noted that it is well

established that international law does not require a State to continue negotiations when it

5.

Exceptions and Limitations to Jurisdiction

161. Finally, the Tribunal examined the subject matter limitations to its jurisdiction set out in
Articles 297 and 298 of the Convention. Article 297 automatically limits the jurisdiction atribunal may exercise over disputes concerning marine scientific research or the living resourcesof the exclusive economic zone. Article 298 provides for further exceptions from compulsory
settlement that a State may activate by declaration for disputes concerning (a) sea boundary
delimitations, (b) historic bays and titles, (c) law enforcement activities, and (d) militaryactivities. By declaration on 25 August 2006, China activated all of these exceptions.
162. The Tribunal considered that the applicability of these limitations and exceptions may depend
upon certain aspects of the merits of the Philippines’ claims:(a)First, the Tribunal noted that its jurisdiction may depend on the nature and validity of any
claim by China to historic rights in the South China Sea and whether such rights arecovered by the exclusion from jurisdiction of “historic bays or titles.”112(b)Second, the Tribunal noted that its jurisdiction may depend on the status of certain
maritime features in the South China Sea and whether the Philippines and China possess
overlapping entitlements to maritime zones in the South China Sea. If so, the Tribunal
may not be able to reach the merits of certain claims because they would first require adelimitation of the overlapping zones (which the Tribunal is not empowered to do).113(c)

Third, the Tribunal noted that its jurisdiction may depend on the maritime zone in which
alleged Chinese law enforcement activities in fact took place.114(d)Fourth, the Tribunal noted that its jurisdiction may depend on whether certain Chinese
activities are military in nature.115

163. The Tribunal recalled that its Rules of Procedure call for it to rule on objections to jurisdiction
as a preliminary matter, but permitted it to rule on such objections in conjunction with the111

merits if the objection “does not possess an exclusively preliminary character.”

For theforegoing reasons, the Tribunal concluded that it was able, at that time, to rule that it has
jurisdiction over certain of the claims brought by the Philippines, but that others were notexclusively preliminary and would be deferred for further consideration in conjunction with themerits.116

THE STATUS AND EFFECT OF THE TRIBUNAL’S AWARD ON JURISDICTION

165. The Tribunal’s Award on Jurisdiction is an “award of the arbitral tribunal” for the purposes of
Article 10 of Annex VII to the Convention. 118 Pursuant to Article 11 of Annex VII to theConvention, “[t]he award shall be final and without appeal, unless the parties to the dispute haveagreed in advance to an appellate procedure. It shall be complied with by the parties to thedispute.”119
166. The Tribunal is conscious that China has not, to date, accepted the decisions in the Tribunal’sAward on Jurisdiction and has stated that the Award “is null and void, and has no binding effecton China.”120 The Tribunal is also conscious that China has continued to assert publicly that the
Tribunal lacks jurisdiction for the same reasons set out in China’s Position Paper of 7 December
2014, specifically that:(a)“First, the essence of the subject-matter of the arbitration is territorial sovereignty over
several maritime features in the South China Sea, which is beyond the scope of the
UNCLOS.”121(b)“Second, even assuming some of the claims were concerned with the interpretation andapplication of the UNCLOS, they would still be an integral part of maritime delimitation,
which has been excluded by China through its 2006 Declaration and consequently is not
subject to compulsory arbitration.”122(c)“Third, given that China and the Philippines have agreed to settle their disputes in theSouth China Sea through negotiation, the Philippines is precluded from initiating
arbitration unilaterally.”123

Award of 12 July 2016(d)

“Fourth, the Philippines failed to fulfill the obligation of exchanging views with China on
the means of dispute settlement.”124

China has also continued to assert its view that (e) “the Philippines’ initiation of the arbitration
is a typical abuse of compulsory arbitral procedures stipulated in the UNCLOS.”125
167. The Tribunal considers that each of these objections—concerning (a) the link between
sovereignty and the Philippines’ claims,126 (b) the link between maritime delimitation and thePhilippines’ claims,127 (c) the effect of the DOC,128 (d) the Parties’ exchange of views on thesettlement of the dispute prior to the commencement of the arbitration, 129 and (e) the
appropriateness of the Philippines’ recourse to arbitration 130 —has been fully addressed anddecided in the Tribunal’s Award on Jurisdiction, in keeping with the Tribunal’s power pursuant
to Article 288(4) to decide any dispute concerning the scope of its own jurisdiction.
168. For the avoidance of doubt, the Tribunal hereby reaffirms in full, and incorporates by reference,the conclusions and reasoning set out in its Award on Jurisdiction.

THE ‘NINE-DASH LINE’ AND CHINA’S CLAIM TO HISTORIC RIGHTS IN THE
MARITIME AREAS OF THE SOUTH CHINA SEA (SUBMISSIONS NO. 1 AND 2)

A.

INTRODUCTION

169. In this Chapter, the Tribunal addresses the Parties’ dispute reflected in the Philippines’
Submissions No. 1 and 2, which request the Tribunal to hold that China is entitled only to thoserights provided for by the Convention and that these rights are not supplemented or modified byany historic rights, including within the area marked by the ‘nine-dash line’ on Chinese maps.131
Submissions No. 1 and 2 are expressed as follows:(1)

China’s maritime entitlements in the South China Sea, like those of the Philippines,
may not extend beyond those expressly permitted by the United Nations Convention
on the Law of the Sea (“UNCLOS” or the “Convention”);(2)

China’s claims to sovereign rights jurisdiction, and to “historic rights” with respect
to the maritime areas of the South China Sea encompassed by the so called “ninedash line” are contrary to the Convention and without lawful effect to the extent thatthey exceed the geographic and substantive limits of China’s maritime entitlements
expressly permitted by UNCLOS;

170. In its Award on Jurisdiction, the Tribunal held that these Submissions reflect a disputeconcerning the source of maritime entitlements in the South China Sea and the interaction ofChina’s claimed historic rights with the provisions of the Convention.132 This dispute does notconcern sovereignty, insofar as the Philippines has asked the Tribunal to determine the source ofrights to maritime areas, and not to decide sovereignty over any land features within the South
China Sea.133 The Tribunal also held that this dispute does not concern maritime boundary
delimitation.134 Finally, the Tribunal emphasised that “[a] dispute concerning the interaction of
the Convention with another instrument or body of law, including the question of whether rights

131

As noted in the Award on Jurisdiction at p. 62, n.121, the ‘nine-dash line’ refers to the dashed line
depicted on maps accompanying the Note Verbale from the Permanent Mission of the People’s Republicof China to the United Nations to the Secretary-General of the United Nations, No. CML/17/2009 (7 May
2009) (Annex 191); Note Verbale from the Permanent Mission of the People’s Republic of China to theUnited Nations to the Secretary-General of the United Nations, No. CML/18/2009 (7 May 2009)(Annex 192). The Tribunal’s use of the term ‘nine-dash line’ is not to be understood as recognising any
particular nomenclature or map as correct or authoritative. The Tribunal observes that different terms
have been used at different times and by different entities to refer to this line. For example, China refers
to “China’s dotted line in the South China Sea” (China’s Position Paper, para. 8); Viet Nam refers to the“nine-dash line” (Viet Nam’s Statement, paras. 2(iii)-(iv), 4(i)); Indonesia has referred to the “so called‘nine-dotted-lines map’ (Note Verbale from the Permanent Mission of the Republic of Indonesia to theUnited Nations to the Secretary-General of the United Nations, No. 480/POL-703/VII/10 (8 July 2010)(Annex 197); and some commentators have referred to it as the “Cow’s Tongue” and “U-Shaped Line.”
As noted below at paragraph 181, the Tribunal observes that the number of dashes varies, depending on
the date and version of the map consulted.

arising under another body of law were or were not preserved by the Convention, is
unequivocally a dispute concerning the interpretation and application of the Convention.”135
171. However, the Tribunal held that a final determination on its jurisdiction with respect to theParties’ dispute is dependent on the nature of any historic rights claimed by China and whether
they are covered by the exclusion from jurisdiction in Article 298 of the Convention for disputes
concerning “historic bays or titles.”Accordingly, the Tribunal deferred a decision on its

jurisdiction for consideration in conjunction with the merits of the Philippines’ claims. 136
B.

CHINA’S DECLARATIONS AND LEGISLATION CONCERNING ENTITLEMENTS TO MARITIME
ZONES172. China has set out its claims to maritime zones in legislation and a series of declarations.
173. When China was under the control of its Republican Government in the 1930s, it issued adecree declaring a territorial sea of three nautical miles. 137 Prior to that declaration China
appears to have distinguished between the “inner ocean” and the “outer ocean” in its domestic
laws, and to have included references to a territorial sea in a number of international
agreements, but never to have fixed the extent or boundaries of that zone.138
174. On 4 September 1958, China issued a Declaration of the Government of the People’s Republicof China on China’s Territorial Sea, which provided in relevant part as follows:
The Government of the People’s Republic of China declares:
1. The breadth of the territorial sea of the People’s Republic of China shall be twelve
nautical miles. This provision applies to all territories of the People’s Republic of China,
including the Chinese mainland and its coastal islands, as well as Taiwan and its
surrounding islands, the Penghu Islands, the Dongsha Islands, the Xisha Islands, theZhongsha Islands, the Nansha Islands and all other islands belonging to China which areseparated from the mainland and its coastal islands by the high seas.
2. China’s territorial sea along the mainland and its coastal islands takes as its
baseline the line composed of the straight lines connecting base-points on the mainland
coast and on the outermost of the coastal islands; the water area extending twelve nautical
miles outward from this baseline is China’s territorial sea. The water areas inside thebaseline, including Bohai Bay and the Chiungchow Straits, are Chinese inland waters. The
islands inside the baseline, including Tungyin Island, Kaoteng Island, the Matsu Islands,
the Paichuan Islands, Wuchiu Island, the Greater and Lesser Quemoy Islands, Tatan Island,
Erhtan Island and Tungting Island, are islands of the Chinese inland waters.

3. No foreign vessels for military use and no foreign aircraft may enter China’s
territorial sea and the air space above it without the permission of the Government of thePeople’s Republic of China.
While navigating Chinese territorial sea, every foreign vessel must observe therelevant laws and regulations laid down by the Government of the People’s Republic ofChina.
4. The principles provided in paragraphs (2) and (3) likewise apply to Taiwan and its
surrounding Islands, the Penghu Islands, the Dongsha islands, the Xisha Islands, theZhongsha Islands, the Nansha Islands, and all other islands belonging to China. 139

175. On 25 February 1992, China enacted a Law on the Territorial Sea and the Contiguous Zone,
which provided in relevant part as follows:
Article 2
The territorial sea of the People’s Republic of China is the sea belt adjacent to the land
territory and the internal waters of the People’s Republic of China.
The land territory of the People’s Republic of China includes the mainland of the People’s
Republic of China and its coastal islands; Taiwan and all islands appertaining thereto
including the Diaoyu Islands; the Penghu Islands; the Dongsha Islands; the Xisha Islands;
the Zhongsha Islands and the Nansha Islands; as well as all the other islands belonging to
the People’s Republic of China.
The waters on the landward side of the baselines of the territorial sea of the People’s
Republic of China constitute the internal waters of the People’s Republic of China.
Article 3
The breadth of the territorial sea of the People’s Republic of China is twelve nautical miles,
measured from the baselines of the territorial sea.
The method of straight baselines composed of all the straight lines joining the adjacent basepoints shall be employed in drawing the baselines of the territorial sea of the People’s
Republic of China.
The outer limit of the territorial sea of the People’s Republic of China is the line every
point of which is at a distance equal to twelve nautical miles from the nearest point of thebaseline of the territorial sea.
Article 4
The contiguous zone of the People’s Republic of China is the sea belt adjacent to andbeyond the territorial sea. The breadth of the contiguous zone is twelve nautical miles.
The outer limit of the contiguous zone of the People’s Republic of China is the line every
point of which is at a distance equal to twenty four nautical miles from the nearest point of
the baseline of the territorial sea.
Article 5
The sovereignty of the People’s Republic of China over its territorial sea extends to the air
space over the territorial sea as well as to the bed and subsoil of the territorial sea. 140

The South China Sea Arbitration
Award of 12 July 2016176. On 15 May 1996, China issued a Declaration of the Government of the People’s Republic ofChina on the Baselines of the Territorial Sea, setting out certain coordinates for the baselines
from which its territorial sea would be measured.141
177. On 7 June 1996, in conjunction with its ratification of the Convention, China declared an
exclusive economic zone in the following terms:
1.

In accordance with the provisions of the United Nations Convention on the Law of
the Sea, the People’s Republic of China shall enjoy sovereign rights and jurisdiction
over an exclusive economic zone of 200 nautical miles and the continental shelf.

2.

The People’s Republic of China will effect, through consultations, the delimitationof boundary of the maritime jurisdiction with the states with coasts opposite or
adjacent to China respectively on the basis of international law and in accordancewith the equitable principle.

3.

The People’s Republic of China reaffirms its sovereignty over all its archipelagoes
and islands as listed in article 2 of the Law of the People’s Republic of China on the
Territorial Sea and Contiguous Zone which was promulgated on 25 February 1992.

4.

The People’s Republic of China reaffirms that the provisions of the United Nations
Convention on the Law of the Sea concerning innocent passage through theterritorial sea shall not prejudice the right of a coastal state to request, in accordancewith its laws and regulations, a foreign state to obtain advance approval from or giveprior notification to the coastal state for the passage of its warships through theterritorial sea of the coastal state.142

178. On 26 June 1998, China enacted a Law on the Exclusive Economic Zone and the Continental
Shelf, which described the extent of China’s exclusive economic zone and continental shelf as
follows:
Article 2
The exclusive economic zone of the People’s Republic of China covers the area beyond andadjacent to the territorial sea of the People’s Republic of China, extending to 200 nautical
miles from the baselines from which the breadth of the territorial sea is measured.
The continental shelf of the People’s Republic of China comprises the sea-bed and subsoilof the submarine areas that extend beyond its territorial sea throughout the natural
prolongation of its land territory to the outer edge of the continental margin, or to a distanceof 200 nautical miles from the baselines from which the breadth of the territorial sea ismeasured where the outer edge of the continental margin does not extend up to that
distance.
The People’s Republic of China shall determine the delimitation of its exclusive economic
zone and continental shelf in respect of the overlapping claims by agreement with the states

C.

CHINA’S CLAIMS TO HISTORIC RIGHTS

180. As the Tribunal noted in its Award on Jurisdiction, the resolution of the Parties’ dispute inrelation to Submissions No. 1 and 2 is complicated by some ambiguity in China’s position. As
far as the Tribunal is aware, China has never expressly clarified the nature or scope of its
claimed historic rights. Nor has it ever clarified its understanding of the meaning of the ‘ninedash line’.145 Certain facts can, however, be established.
181. What has become known as the ‘nine-dash line’ first appeared on an official Chinese map in1948. In that year, the Ministry of the Interior of the then Republican Government of China
published a “Map Showing the Location of the Various Islands in the South Sea” (the “1948
Map”). 146 A similar line had also appeared in privately produced cartography as early as
1933.147 The 1948 Map is reproduced as Figure 1 on page 75 below. In this original form, themap featured 11 dashes. The two dashes in the Gulf of Tonkin were removed in 1953, 148
rendering it a ‘nine-dash line’, and the line has appeared consistently in that nine-dash form in

official Chinese cartography since that date.149 The length and precise placement of individual
dashes, however, do not appear to be entirely consistent among different official depictions of
the line.
182. On 7 May 2009, China sent two Notes Verbales to the UN Secretary-General in response to
Malaysia and Viet Nam’s Joint Submission of the preceding day to the Commission on the
Limits of the Continental Shelf (the “CLCS”). In its notes, China stated as follows:
China has indisputable sovereignty over the islands in the South China Sea and the adjacentwaters, and enjoys sovereign rights and jurisdiction over the relevant waters as well as theseabed and subsoil thereof (see attached map). The above position is consistently held by
the Chinese Government, and is widely known by the international community. 150

183. Appended to China’s notes was a map depicting the ‘nine-dash line’ (the “2009 Map”), whichis reproduced as Figure 2 on page 77 below.
184. China’s notes prompted immediate objections from Viet Nam and Malaysia, 151 as well as
subsequent objections from Indonesia 152 and the Philippines. 153

In addition to claiming

sovereignty over the “Kalayaan Island Group (KIG)”, the Philippines’ objection stated in
relevant part:On the “Waters Adjacent” to the Islands and other Geological Features
SECOND, the Philippines, under the Roman notion of dominium maris and theinternational law principle of “la terre domine la mer” which states that the land dominates
the sea, necessarily exercises sovereignty and jurisdiction over the waters around or
adjacent to each relevant geological feature in the KIG as provided for under the United
Nations Convention on the Law of the Sea (UNCLOS).

The Tribunal notes that, in 2013, China issued a new official map of China with a vertical orientation anda tenth dash to the east of Taiwan island. See China Cartographic Publishing House, “Map of thePeople’s Republic of China” (2013). The Tribunal understand that this does not reflect a change in thecourse of the ‘nine-dash line’, but rather the fact that prior projections using a horizontal orientation andan inset map of the South China Sea had the effect of obscuring the area east of Taiwan island on the inset
map. See, e.g., Map of the People’s Republic of China, China Cartographic Publishing House (1992).

At any rate, the extent of the waters that are “adjacent” to the relevant geological features
are definite and determinable under UNCLOS, specifically under Article 121 (Regime ofIslands) of the said Convention.
On the Other “Relevant Waters, Seabed and Subsoil” in the SCS
THIRD, since the adjacent waters of the relevant geological features are definite andsubject to legal and technical measurement, the claim as well by the People’s Republic ofChina on the “relevant waters as well as the seabed and subsoil thereof” (as reflected in theso-called 9-dash line map attached to Notes Verbales CML/17/2009 dated 7 May 2009 andCML/18/2009 dated 7 May 2009) outside of the aforementioned relevant geologicalfeatures in the KIG and their “adjacent waters” would have no basis under internationallaw, specifically UNCLOS. With respect to these areas, sovereignty and jurisdiction orsovereign rights, as the case may be, necessarily appertain or belong to the appropriate
coastal or archipelagic state – the Philippines – to which these bodies of waters as well as
seabed and subsoil are appurtenant, either in the nature of Territorial Sea, or 200 M
Exclusive Economic Zone (EEZ), or Continental Shelf (CS) in accordance with Articles 3,4, 55, 57, and 76 of UNCLOS. 154

185. In response to the Philippines, China restated its position as follows:
China has indisputable sovereignty over the islands in the South China Sea and the adjacentwaters, and enjoys sovereign rights and jurisdiction over the relevant waters as well as theseabed and subsoil thereof. China’s sovereignty and related rights and jurisdiction in theSouth China Sea are supported by abundant historical and legal evidence. The contents of
the Note Verbale No 000228 of the Republic of Philippines are totally unacceptable to theChinese Government.
. . . Furthermore, under the legal principle of “la terre domine la mer”, coastal states’
Exclusive Economic Zone (EEZ) and Continental Shelf claims shall not infringe upon the
territorial sovereignty of other states.
Since 1930s, the Chinese Government has given publicity several times the geographicalscope of China’s Nansha Islands and the names of its components. China’s Nansha Islands
is therefore clearly defined. In addition, under the relevant provisions of the 1982 United
Nations Convention on the Law of the Sea, as well as the Law of the People’s Republic ofChina on the Territorial Sea and the Contiguous Zone (1992) and the Law on the Exclusive
Economic Zone and the Continental Shelf of the People’s Republic of China–(1998),
China’s Nansha Islands is fully entitled to Territorial Sea, Exclusive Economic Zone (EEZ)
and Continental Shelf.155

186. China has repeated variations on this formula in its diplomatic correspondence156 and in the
public statements of its official spokespersons,157 and has expressly linked the ‘nine-dash line’to China’s claim to rights “formed over a long course of history”:

China has indisputable sovereignty over the Nansha Islands and their adjacent waters. And
it is an indisputable fact that the Xisha Islands are an integral part of China’s territory. As
early as 1948, the Chinese government published an official map which displayed “thedotted line” in the South China Sea. China’s sovereignty over the South China Sea and its
claims to the relevant rights have been formed over a long course of history. They aresolidly grounded in international law and have been consistently upheld by successive
Chinese governments.158

187. China’s formal statement, released following the Tribunal’s issuance of the Award on
Jurisdiction, is representative of China’s consistent characterisation of its maritime entitlementsin the South China Sea:
China has indisputable sovereignty over the South China Sea Islands and the adjacentwaters. China’s sovereignty and relevant rights in the South China Sea, formed in the long
historical course, are upheld by successive Chinese governments, reaffirmed by China’s
domestic laws on many occasions, and protected under international law including theUnited Nations Convention on the Law of the Sea (UNCLOS). . . .159

THE PHILIPPINES’ POSITION

188. The Philippines submits that the Tribunal has jurisdiction to consider its Submissions
No. 1 and 2. On the merits, the Philippines argues both (a) that any rights that China may have
had in the maritime areas of the South China Sea beyond those provided for in the Convention
were extinguished by China’s accession to the Convention and (b) that China never had historicrights in the waters of the South China Sea.

Jurisdiction

189. With respect to jurisdiction, the Philippines argues that China’s statements since May 2009
make a consistent distinction between claims to “sovereignty” and claims to “sovereign rights
and jurisdiction,” and a further distinction between the “islands in the South China Sea and theadjacent waters” and the “relevant waters”. According to the Philippines:
the most logical way to construe China’s language is as an assertion of sovereignty over theislands of the South China Sea and their “adjacent waters”, or territorial seas; and a claim ofsovereign rights and jurisdiction—short of sovereignty—in the waters that lie between the
territorial seas claimed by China and the nine-dash line.160

190. In the Philippines’ view, the nature of China’s claim as one of sovereign rights and jurisdiction
is confirmed by China’s conduct in (a) seeking to ban fishing by other States within the‘nine-dash line’; (b) interfering with the Philippines’ petroleum exploration activities; and (c)offering concessions to oil blocks in areas within the ‘nine-dash line’ but beyond the possible
limits of China’s entitlements under the Convention. 161 At the same time, the Philippines
considers that China’s conduct makes clear that its claim is not to sovereignty over the entire
area within the ‘nine-dash line’, insofar as China has repeatedly asserted that it respects freedomof navigation and overflight in the South China Sea. 162 The Philippines also notes that thisinterpretation of China’s position has been adopted by numerous Chinese scholars, including
those with significant links to the government.163
191. According to the Philippines, the exception to jurisdiction in Article 298 of the Convention islimited to disputes involving “historic bays or titles.” Moreover, the Philippines argues, “theconcept of ‘historic title’ as used in Article 298 has a specific and limited meaning: it pertains
only to near-shore areas of sea that are susceptible to a claim of sovereignty as such.” 164
Because the Philippines understands China’s claims to fall short of sovereignty over the
maritime areas of the South China Sea (beyond the “islands” and “adjacent waters”), thePhilippines considers that China’s claim cannot be one of historic title. In this respect, thePhilippines argues that there is a consistent distinction—including in the Chinese terminology—
between China’s use of the term “historical rights” in China’s Exclusive Economic Zone and160

Continental Shelf Act 165 and the term ‘historic title’ in Article 298 and elsewhere in theConvention. As such, the Philippines argues, “China’s claim of ‘historic rights’ within the area
encompassed by the nine-dash line is not covered by Article 298(1)(a)(i).”166 Even if China’s
claim were to a historic title, however, the Philippines submits that Article 298 would
nevertheless be inapplicable because the article applies only to disputes over the delimitation ofhistoric bays and titles. According to the Philippines, “when Article 298(1)(a)(i) refers to ‘those
involving historic bays or titles’ the ‘those’ being referred to are not disputes generally but
rather disputes concerning delimitation.”167
2.

China’s Claim to Historic Rights

192. With respect to the merits, the Philippines’ argument is two-fold. First, the Philippines submits
that international law did not historically permit the type of expansive claim advanced by
China’s ‘nine-dash line’ and that, even if China did possess historic rights in the South China
Sea, any such rights were extinguished by the adoption of the Convention.

Second, thePhilippines argues that, on the basis of the historical record of China’s activities in the South
China Sea, China cannot meet the criteria for having established historic rights within the ‘ninedash line’.
193. According to the Philippines, international law prior to the adoption of the Convention did not
accept “assertions of historic rights over such a vast area” as China now claims. 168 Prior to theConvention, the Philippines argues, “[t]he sea was subject only to two principles: the principleof the freedom of the seas, which prohibits appropriation by any state; and the principle ofcontrol over a limited area by the immediately adjacent coastal state, which prohibits
appropriation by any other state.”169 In the Philippines’ view, “China’s claim . . . is inconsistent
with both principles.”170

194. With the adoption of the Convention, the Philippines submits, the States Parties considered“with careful specificity the nature of prior uses [of the sea] that are protected, the nature of theprotections, and the areas in which such protections apply.”171 According to the Philippines,
where the Convention makes no express exception for prior uses or rights “those historic rights
would not have survived as derogations from the sovereignty, sovereign rights and high seas
freedoms of other states.”172 Notably, while some protections of prior uses were accepted, thePhilippines argues that “distant water fishing states failed to obtain recognition in the exclusive
economic zone of historic fishing rights derived from prior high seas fishing.” 173 In the courseof these debates, the Philippines submits:
China was a vocal supporter of the demands of developing coastal states for exclusive
jurisdiction over the natural resources in the EEZs and continental shelves off theirrespective coasts, and China was a consistent critic of attempts to limit the content of thatjurisdiction. China identified itself as one of those developing coastal states. It made no
attempt whatsoever to secure an exception protecting historic claims of maritime rights of
the kind that are now at issue. 174

Accordingly, the Philippines concludes, “[t]he Convention leaves no room for assertions ofrights to control activities beyond [the limits fixed in the Convention] in derogation of thesovereign rights of other coastal states or the rights and freedoms of all states.”175
195. The Philippines also challenges the existence of Chinese historic rights in the maritime areas of
the South China Sea. According to the Philippines, China “first claimed the existence of suchrights on 7th May 2009.”176 The Philippines submits that Chinese historic maps dating back to1136, including those purporting to depict the entirety of the Empire of China, consistently
show China’s territory extending no further south than Hainan.177 The Philippines also notes
that, for periods of the 14th century and for much of the 15th and 16th centuries, the Imperial
Chinese Government actively prohibited maritime trade by Chinese subjects. 178 Indeed, thePhilippines notes:
During the mid-15th century, for instance, the Ming authorities suppressed maritime
activities, and in 1500 made it a capital offence to build two-masted ships. In 1525, all such

remaining ships were ordered destroyed. In 1551, China defined venturing out to sea in a
multi-masted ship to be an act of treason.179

196. This ambivalent attitude to seafaring explains, for the Philippines, China’s muted reaction to theactivities of European States in the South China Sea and its lack of protest to European
navigation and the establishment of colonies in Southeast Asia, beginning in the 16th century.
197. Reviewing the published archival records of the Taiwan Authority of China, 180 which thePhilippines considers to comprise documents selected to support China’s claims, the Philippinesemphasises the absence of “any documents evidencing any official Chinese activities in regard
to any South China Sea feature prior to the beginning of the 20th century.”181 The Philippines
also emphasises a Note Verbale from the Legation of the Chinese Republic in France to the
French Ministry of Foreign Affairs in 1932, stating that the Paracel Islands “form thesouthernmost part of Chinese territory.”182 According to the Philippines, when China “sought toassert its claim to the South China Sea islands,”183 following the defeat of Japanese forces in theSecond World War, the plans included an effort to develop Chinese names for the features, themajority of which were then identified only by Chinese transliterations of their English
names.184 According to the Philippines “Lord Auckland Shoal was thus ‘Ao ke lan sha’, andMischief Reef ‘Mi-qi fu’. Gaven Reef was ‘Ge wen’, and Amy Douglas Reef ‘A mi de ge la’.”185
Based on this record, the Philippines questions how China could have historic rights in an area
“over which it had so little involvement or connection that most of the features had no Chinese
names.”186

198. According to the Philippines, the absence of any Chinese historic rights in the South China Sea
is also apparent in various historical documents obtained by the Tribunal from the Bibliothèque
Nationale de France and the Archives Nationales d’Outre-Mer and provided to the Parties forcomment. In the Philippines’ view, these documents confirm that “prior to the Second WorldWar France did not consider China to have made a claim in regard to any of the Spratlys, or to
the waters of the South China Sea far removed from China’s mainland coast.”187 Additionally,“the post-war documents—including France’s internal records—make clear that France retained
its claim to those features,” a position the Philippines considers consistent with its view that theUnited Kingdom and United States “wished to protect France’s sovereignty claim” inconnection with the Cairo Declaration and Potsdam Proclamation.188
199. In any event, the Philippines argues that any Chinese historical claims to the features of theSouth China Sea did not, until 2009, “include a claim to the waters beyond their territorial
seas.”189 The Philippines notes China’s support of the three-mile territorial sea limit during theSecond UN Conference on the Law of the Sea in 1960, 190 as well as the fact that China’s
Declaration of the Government of the People’s Republic of China on China’s Territorial Sea
refers to the Spratly Islands as being “separated from the mainland and its coastal islands by thehigh seas,” and not by any maritime area in which China had particular entitlements.191 The
Philippines argues that this has also been the understanding, until recently, of Chinese scholars
working from the archives of the People’s Republic of China.192 Finally, when China did makeclear in May 2009 that it claims historic rights in the maritime areas within the ‘nine-dash line’,
the Philippines submits that this was promptly objected to by the other littoral States of theSouth China Sea.193 As such, the Philippines submits that China has no historic rights withinthe ‘nine-dash line’.

CHINA’S POSITION

200. China’s various statements indicating that it claims historic rights in the South China Sea within
the area of the ‘nine-dash line’ are set out above at paragraphs 180 to 187. On 12 May 2016,
when the Director-General of the Department of Treaty and Law at the Chinese Ministry ofForeign Affairs was asked about the ‘nine-dash line’ in the context of the present arbitration, he
responded with the following statement:
The “nine-dash line” . . . is called by China the dotted line. I want to stress that China’s
sovereignty and relevant rights in the South China Sea were formed throughout the longcourse of history and have been maintained by the Chinese Government consistently.
Early in 1948, the dotted line was mapped on China’s official map. It was a confirmationof China’s rights in the South China Sea formed throughout the history, instead of creationof new claims. For a long time, no State questioned the legitimacy of the dotted line and it
also appeared on the official maps of many States.
In recent years, some States started to attack on China’s dotted line. The real motive is tointentionally confuse territorial disputes with disputes over maritime delimitation, deny
China’s sovereignty over the South China Sea Islands and their adjacent waters, and coverup their illegal invasion and occupation of part of the maritime features of China’s Nansha
Islands.
In the Arbitration, the Philippines requested the Arbitral Tribunal to decide whether
maritime entitlements claimed by China in the South China Sea exceeded the limits of the
UNCLOS . . . . [T]o answer this question, we need to decide China’s territorial sovereignty
first. In accordance with international law, territorial sovereignty is the basis of maritime
rights. Without first determining China’s territorial sovereignty over the maritime
f[ea]tures in the South China Sea, it would not be possible to determine maritime
entitlements China may claim in it pursuant to the UNCLOS, let alone determine whether
China’s maritime claims in the South China Sea have exceeded the extent allowed under
the UNCLOS.
On the other hand, we have to note that the dotted line came into existence much earlier
than the UNCLOS, which does not cover all aspects of the law of the sea. No matter fromwhich lens we look at this, the Tribunal does not have jurisdiction over China’s dotted line.
As to negotiations, China has reiterated its hope that the relevant parties should resolve thedisputes through consultation and negotiation based on historical facts and internationallaw. The door of negotiation remains open. 194

201. China has not explained the nature of these claims in the course of these proceedings. The
Tribunal will address the nature of China’s claims to historic rights in the context of considering
its jurisdiction with respect to the Philippines’ Submissions No. 1 and 2.

THE TRIBUNAL’S CONSIDERATIONS
1.

The Tribunal’s Jurisdiction

202. Article 298 of the Convention provides in relevant part as follows:
Article 298
Optional exceptions to applicability of section 2
1.

When signing, ratifying or acceding to this Convention or at any time thereafter, aState may, without prejudice to the obligations arising under section 1, declare in
writing that it does not accept any one or more of the procedures provided for in
section 2 with respect to one or more of the following categories of disputes:
(a)

(i)

disputes concerning the interpretation or application of articles 15,
74 and 83 relating to sea boundary delimitations, or those involving
historic bays or titles . . . .

203. On 25 August 2006, China issued a declaration pursuant to Article 298, activating all of theoptional exceptions to jurisdiction in the following terms: “[t]he Government of the People’s
Republic of China does not accept any of the procedures provided for in Section 2 of Part XV of
the Convention with respect to all the categories of disputes referred to in paragraph 1 (a), (b)and (c) of Article 298 of the Convention.”195204. The Tribunal has already addressed the first exception to jurisdiction in Article 298(1)(a)(i) of
the Convention, which applies to disputes concerning the interpretation or application ofarticles 15, 74, and 83 of the Convention relating to sea boundary delimitations, and found it
inapplicable in the present case.196 In brief, a dispute over the source and existence of maritime
entitlements does not “concern” sea boundary delimitation merely because the existence ofoverlapping entitlements is a necessary condition for delimitation. While all sea boundary
delimitations will concern entitlements, the converse is not the case:all disputes overentitlements do not concern delimitation. Where, as here, a party denies the existence of anentitlement, a possible outcome may well be the absence of any overlap and any possibility ofdelimitation. The exception in Article 298(1)(a)(i) of the Convention does not reach so far as tocapture a dispute over the existence of entitlements that may—or may not—ultimately requiredelimitation.
205. What remains for the Tribunal in the present decision is the second exception to jurisdiction in
Article 298(1)(a)(i) of the Convention, which applies to disputes involving historic bays or

titles. The concept of a historic bay is well understood in international law197 and, as a matter ofplain geography, the South China Sea is not a bay.198 The question is therefore whether China
potentially claims historic title in the South China Sea and, if so, the implications for the
Tribunal’s jurisdiction.
206. Whether the Parties’ dispute involves historic titles, therefore, depends first upon the nature of
China’s claims in the South China Sea and, second, on the scope of the exception. It is for
China to determine the scope of its maritime claims. As far as the Tribunal is aware, however,
the most insightful formulation by China of its claims in the South China Sea, beyond its claim
to sovereignty over islands and their adjacent waters, is as a claim to “relevant rights in theSouth China Sea, formed in the long historical course.”199 In the absence of a more specificindication from China itself, it necessarily falls to the Tribunal to ascertain, on the basis of
conduct, whether China’s claim amounts to ‘historic title’.
(a)

The Nature of China’s Claimed Rights in the South China Sea

207. Since 1956, China has proclaimed a series of maritime zones—a territorial sea, a contiguouszone, a continental shelf, and an exclusive economic zone—that are, at least in general terms, inline with those anticipated by the Convention. Nevertheless, China’s repeated invocation ofrights “formed in the long historical course” and its linkage of this concept with the ‘nine-dashline’ indicates that China understands its rights to extend, in some form, beyond the maritime
zones expressly described in the Convention. The Tribunal therefore turns to the rights that
China has actually invoked in the South China Sea. Much of the area encompassed by the‘nine-dash line’, however, would also fall within a claim to an exclusive economic zone orcontinental shelf drawn from the various features of the Spratly Islands. Whether or not the
Tribunal would agree that the Convention or the features support such entitlements, a matterdiscussed in Chapter VI below, the mere fact that China asserts rights in the South China Sea
does not indicate that China considers those rights to derive from the ‘nine-dash line’. Where,
however, China has asserted rights in areas beyond the maximum entitlements that could beclaimed under the Convention, the Tribunal considers that such assertions indicate a claim to197

86

Award of 12 July 2016

rights arising independently of the Convention. There are at least three instances when China
appears to have asserted such rights.
208. In June 2012, the China National Offshore Oil Corporation (“CNOOC”) issued a notice of open
blocks for petroleum exploration adjacent to the western edge of the ‘nine-dash line’.200 The
western portions of at least one of these blocks (Block BS16) lie beyond 200 nautical miles
from any feature in the South China Sea claimed by China,201 and beyond any possible extended
continental shelf.202 The map appended to the CNOOC tender is reproduced as Figure 3 onpage 89. The Tribunal acknowledges that the affected area of the ‘nine-dash line’ is not of
direct relevance to the Philippines’ own maritime claims, but nevertheless notes that China’s
2012 notice assists in understanding the nature of China’s claims within the ‘nine-dash line’.
Thus, with respect to some areas of the blocks, even assuming the maximum possible claim to
entitlements that China could make under the Convention, China’s authority to issue thepetroleum blocks in question cannot be based solely upon entitlements derived from theConvention.
209. China has also objected to the Philippines’ award of petroleum blocks within the ‘nine-dashline’, an issue discussed in greater detail in connection with the Philippines’ Submission No. 8.
The area of the Philippines’ petroleum blocks could be almost covered by entitlements claimedby China under the Convention, if China were understood to claim an exclusive economic zone
from all high-tide features in the Spratly Islands, no matter how small, and from ScarboroughShoal. The fact of China’s objection is thus not necessarily indicative of the source of China’s
claimed rights. When, however, China objected to the Philippines’ Geophysical Survey andExploration Contract 101 petroleum block (“GSEC101”) (depicted in Map 4 on page 269), thePhilippines recorded China’s Chargé d’Affaires in Manila as stating that “[s]ince ancient times,
China has indisputable sovereignty over the Nansha islands and its adjacent waters. The GSEC

This remains the case even if a full exclusive economic zone were ascribed to the single small rock above
water at high tide at Fiery Cross Reef (discussed below at paragraphs 340 to 343 and 563 to 565).

202

The Tribunal takes note of the Expert Report submitted by Dr. Lindsay Parson and his conclusion that,while China could potentially claim certain areas of continental shelf beyond 200 nautical miles, as amatter of geomorphology, the Spratly Islands would be unlikely to support a claim beyond 200 nautical
miles and that the Paracel Islands would be unlikely to significantly extend China’s maritime areas
beyond a continental shelf that could be claimed from Hainan. Dr. Lindsay Parson, The Potential for
China to Develop a Viable Submission for Continental Shelf Area beyond 200 Nautical Miles in the South
China Sea, pp. 5-6, 9, 37-38 (March 2015) (Annex 514).

101 (SC 72) area is situated in the adjacent waters of the Nansha Islands (Spratlys).” 203
Similarly, when China objected to the Philippines’ Service Contract 58 (“SC58”) block, thePhilippines recorded China’s Deputy Chief of Mission in Manila as stating that “Service
Contract 54, 14, 58, 63, and other nearby service contracts are located ‘deep within China’s
9-dash line.’”204 Finally, China objected to the Philippines’ Area 3 and Area 4 petroleum blocks
by Note Verbale:
On 30 June 20l1 at the launching of Fourth Philippine Energy Contracting Round (PECR4),
the Department of Energy of the Philippines offered 15 petroleum blocks to local andinternational companies for exploration and development. Among the aforesaid blocks,
AREA 3 and AREA 4 are situated in the waters of which China has historic titles including
sovereign rights and jurisdiction. 205

Despite the possibility that China’s claims were based on a theory of entitlement to continental
shelf rights pursuant to the Convention, the framing of China’s objections strongly indicates that
China considers its rights with respect to petroleum resources to stem from historic rights.
210. A similar conclusion is suggested by China’s declaration, in May 2012, of a “Summer Ban on
Marine Fishing in the South China Sea Maritime Space,” in order to “protect and rationallyutilise South China Sea fishery resources.”206 The announcement described the ban and the area
in which it would apply as follows:
All productive activity types, except for using single-layer gill net and line-fishingequipment, shall be prohibited from 16 May 12:00 p.m. until 1 August 12:00 p.m. in theSouth China Sea areas from 12º north latitude up to the “Common Boundary Line of
Fujian-Guangdong Sea Areas” (including the Gulf of Tonkin) under the jurisdiction of thePeople’s Republic of China. 207

211. This description is not entirely clear with respect to the source of China’s claimed right torestrict fishing in the South China Sea areas. That is because first, it applies ultimately only to
areas “under the jurisdiction of the People’s Republic of China,” although a description of the203

Award of 12 July 2016ban by Xinhua, the official press agency of China, noted that it applied “in most parts of theSouth China Sea . . . including Huangyan Island [Scarborough Shoal].”208 Second, the area
north of 12° north latitude could be almost entirely covered by entitlements claimed from theConvention, if China were understood to claim an exclusive economic zone from the very small
rocks of Scarborough Shoal.209 However, taken together with the conclusion above about the
grant of petroleum blocks and China’s frequent references to historic rights without further
specification, the Tribunal concludes that China does claim rights to petroleum resources andfisheries within the ‘nine-dash line’ on the basis of historic rights existing independently of theConvention.
212. At the same time, China has unequivocally stated that it respects freedom of navigation andoverflight in the South China Sea. On 27 October 2015, China’s Vice Foreign Minister statedthat “[t]he Chinese side respects and safeguards the freedom of navigation and over-flight in theSouth China Sea to which all countries are entitled under international law . . . . There has been
and will be no obstruction to navigation and over-flight freedom in the South China Sea.”210
The same commitment has been repeated in numerous other statements by Chinese officials andspokespersons.
213. Within the territorial sea, the Convention does not provide for freedom of overflight or for
freedom of navigation, beyond a right of innocent passage. 211 Accordingly, the Tribunal
considers China’s commitment to respect both freedom of navigation and overflight to establishthat China does not consider the sea areas within the ‘nine-dash line’ to be equivalent to its
territorial sea or internal waters. The Tribunal also notes that China declared baselines for the
territorial sea surrounding Hainan and the Paracel Islands (see paragraph 176 above). In theview of the Tribunal, China would presumably not have done so if the waters both within andbeyond 12 nautical miles of those islands already formed part of China’s territorial sea (orinternal waters) by virtue of a claim to historic rights through the ‘nine-dash line’.
214. In sum, on the basis of China’s conduct, the Tribunal understands that China claims rights to theliving and non-living resources within the ‘nine-dash line’, but (apart from the territorial sea

generated by any islands) does not consider that those waters form part of its territorial sea orinternal waters. The Tribunal will now consider whether a dispute concerning such a claim falls
within the exception to compulsory jurisdiction for “historic bays or titles” in
Article 298(1)(a)(i) of the Convention.
(b)

The Scope of the Exception in Article 298(1)(a)(i) of the Convention

215. In assessing the scope of the exception in Article 298(1)(a)(i), the Tribunal notes, as an initialmatter, that it disagrees with the Philippines that the exception can be dispensed with on the
grounds that, properly interpreted, the exception applies only to “delimitations . . . involving
historic bays or titles.”212 The Tribunal considers this interpretation to be contrary to the natural
reading of even the English text, but agrees that at least the English text of this Article ispotentially ambiguous. The Convention is a multi-lingual instrument, however, and pursuant to
Article 320 of the Convention, “the Arabic, Chinese, English, French, Russian and Spanish texts
are equally authentic.” No comparable ambiguity is to be found in the Chinese, French,
Russian, or Spanish versions of the Convention, each of which is structured so as to make clearthat the exception extends to “disputes . . . involving historic bays or titles,” whether or not suchdisputes involve delimitation.
216. Article 33 of the Vienna Convention on the Law of Treaties (the “Vienna Convention on the
Law of Treaties” or the “Vienna Convention”) addresses the interpretation of a treaty
authenticated in multiple languages and provides that, unless otherwise indicated, “the text is
equally authoritative in each language.”213 Article 33 of the Vienna Convention also provides
that “when a comparison of the authentic texts discloses a difference of meaning which theapplication of articles 31 and 32 does not remove, the meaning which best reconciles the texts,
having regard to the object and purpose of the treaty, shall be adopted.”214 In the present case,and noting that the Convention is silent on the resolution of differences between its different
versions, the Tribunal considers that the broader exception in the non-English texts, for“disputes . . . involving historic bays or titles,” best reconciles the different versions.
217. Article 298(1)(a)(i) of the Convention provides for an exception for disputes involving ‘historic
titles’. While the ordinary meaning of this term already implies a notion of property, the212

92The South China Sea Arbitration

Tribunal considers that the meaning of the Convention’s reference to ‘historic titles’ should beunderstood in the particular context of the evolution of the international law of the sea.
218. The genesis of the present Convention dates back at least to the League of Nations Codification
Conference which met in The Hague in March and April 1930. The regime of the territorial sea
was among the topics considered, and the Preparatory Committee of the Conference
recommended that the Conference seek to identify the bays claimed as “historic bays”.215 No
convention, however, resulted from the Conference.
219. Efforts at codification next moved to the International Law Commission, which submitted a setof draft articles to the General Assembly in 1956. Article 7 of these draft articles addressed thesubject of bays and Article 7(4) provided that “[t]he foregoing provisions shall not apply to
so-called ‘historic’ bays.”216 The commentaries to the draft articles also noted that the breadthof the territorial sea, which was not then agreed upon, could be determined up to 12 nautical
miles on the basis of “historic rights”.217
220. Prior to the First UN Conference on the Law of the Sea, the UN Secretariat prepared an
influential memorandum on historic bays which noted as follows:
the theory of historic bays is of general scope. Historic rights are claimed not only inrespect of bays, but also in respect of maritime areas which do not constitute bays, such as
the waters of archipelagos and the water area lying between an archipelago and theneighbouring mainland; historic rights are also claimed in respect of straits, estuaries andother similar bodies of water. There is a growing tendency to describe these areas as“historic waters”, not as “historic bays”. 218

The report also recalled the observation of the International Court of Justice in
Anglo-Norwegian Fisheries that “[b]y ‘historic waters’ are usually meant waters which aretreated as internal waters but which would not have that character were it not for the existence

Award of 12 July 2016of an historic title”219 and discussed the formation of rights to a historic bay in terms of theformation of historic title.220
221. The first reference to historic title in the treaties preceding the present Convention appears in the1958 Geneva Convention on the Territorial Sea and the Contiguous Zone, Article 12 of which
addresses the delimitation of territorial sea, but provides that “[t]he provisions of thisparagraph shall not apply, however, where it is necessary by reason of historic title or otherspecial circumstances to delimit the territorial seas of the two States in a way which is atvariance with this provision.”221 This provision was introduced by Norway, reflecting its recent
experience before the International Court of Justice. 222 As used in Article 12 of the 1958
Convention, ‘historic title’ was clearly intended to have the same meaning as its usage in
Anglo-Norwegian Fisheries, namely as an area of sea claimed exceptionally as internal waters(or, possibly, as territorial sea). At the close of the First Conference, a resolution was adopted
on the initiative of India and Panama, requesting the General Assembly to “make appropriatearrangements for the study of the juridical regime of historic waters including historic bays, andfor the result of these studies to be sent to all Member States of the United Nations.”223 The
General Assembly referred the matter to the International Law Commission, which did not,however, take it up.
222. In 1962, following the Second UN Conference on the Law of the Sea, the UN Secretariat
produced a memorandum on historic waters, which considered the term as equivalent to historic
title. As with historic bays, the UN Secretariat noted that such historic waters “would beinternal waters or territorial sea according to whether the sovereignty exercised over them in thecourse of the development of the historic title was sovereignty as over internal waters or219

sovereignty as over the territorial sea.”224 The memorandum analyses the formation of historic
title as a process of acquiring a historic right225—a term which is used generally—and concludes
that:
In determining whether or not a title to “historic waters” exists, there are three factors
which have to be taken into consideration, namely,(i)

The authority exercised over the area by the State claiming it as “historic waters”;(ii)

The continuity of such exercise of authority;(iii)

The attitude of foreign States.226

223. During the Third United Nations Conference on the Law of the Sea (the “Third UN
Conference”), Article 12 of the 1958 Convention was adopted as Article 15 of the 1982
Convention, without significant discussion. The principal proponent of the concept of historic
title in the course of the Conference was, in fact, the Philippines, which employed the term withrespect to a claim (which it has since abandoned) to a territorial sea within the lines fixed by theTreaty of Paris of 1898 between Spain and the United States that governed the cession of thePhilippines.227
224. In recent years, the International Court of Justice has twice had the occasion to distinguishbetween historic fishing rights and historic title that would bear on the entitlement to maritime
zones. In Qatar v. Bahrain, the Court noted that historic pearl fishing “seems in any event
never to have led to the recognition of an exclusive quasi-territorial right to the fishing grounds
themselves or to the superjacent waters.” 228 Similarly, in Continental Shelf (Tunisia/Libyan
Arab Jamahiriya), the Court distinguished the legal basis for historic Tunisian fishing rights—
on which it ultimately refrained from ruling—from the regime of the continental shelf.229

225. The purpose of this extended recitation is to emphasise that there exists, within the context ofthe law of the sea, a cognizable usage among the various terms for rights deriving from
historical processes. The term ‘historic rights’ is general in nature and can describe any rightsthat a State may possess that would not normally arise under the general rules of internationallaw, absent particular historical circumstances. Historic rights may include sovereignty, but
may equally include more limited rights, such as fishing rights or rights of access, that fall wellshort of a claim of sovereignty. ‘Historic title’, in contrast, is used specifically to refer tohistoric sovereignty to land or maritime areas. ‘Historic waters’ is simply a term for historic
title over maritime areas, typically exercised either as a claim to internal waters or as a claim to
the territorial sea, although “general international law . . . does not provide for a single ‘régime’for ‘historic waters’ or ‘historic bays’, but only for a particular régime for each of the concrete,
recognised cases of ‘historic waters’ or ‘historic bays’.”230 Finally, a ‘historic bay’ is simply abay in which a State claims historic waters.
226. The Tribunal is of the view that this usage was understood by the drafters of the Convention andthat the reference to ‘historic titles’ in Article 298(1)(a)(i) of the Convention is accordingly areference to claims of sovereignty over maritime areas derived from historical circumstances.
This accords with the only other direct usage of the term, in Article 15 of the Convention, where
historical sovereignty would understandably bear on the delimitation of the territorial sea.
Other “historic rights”, in contrast, are nowhere mentioned in the Convention, and the Tribunal
sees nothing to suggest that Article 298(1)(a)(i) was intended to also exclude jurisdiction over abroad and unspecified category of possible claims to historic rights falling short of sovereignty.
227. The terminological distinction outlined above exists also in Chinese, and the Philippines haspressed on the Tribunal the fact that in its public statements, China has invoked its “historicrights” (li shi xing quan li, or 历史性权利) in the South China Sea, rather than historic title(li shi xing suo you quan, or 历史性所有权) as that term appears in the official Chinese text of
the Convention.231 For its part, the Tribunal notes that China’s usage has not been entirely
consistent, and that at least the English version of China’s Note Verbale of 6 July 2011 (ofwhich only the English version is in the record before the Tribunal) refers to “waters of which
China has historic titles including sovereign rights and jurisdiction.”232 This instance is at odds
with the vast majority of China’s statements, however, and the Tribunal considers that it more

The South China Sea Arbitration
Award of 12 July 2016

likely represents an error in translation or an instance of imprecise drafting, rather than a claimby China to sovereignty over the entirety of the South China Sea.
228. More importantly, however, the Tribunal does not see that the absence of a claim to historic title
can be inferred from China’s use of the broader and less-specific term, as historic title
constitutes one form of historic right. For the Tribunal, the dispositive proof that China’s claim
is not one to historic title lies in China’s conduct, which as discussed above (see paragraphs 207
to 214) is incompatible with a claim that the waters of the South China Sea constitute China’s
territorial sea or internal waters.
229. Having concluded that the exception to jurisdiction in Article 298(1)(a)(i) is limited to disputes
involving historic titles and that China does not claim historic title to the waters of South China
Sea, but rather a constellation of historic rights short of title, the Tribunal holds that it has
jurisdiction to consider the Philippines’ Submissions No. 1 and 2. As China has not made sucha claim, the Tribunal need not consider whether there would be any limit to the application of
Article 298 to expansive claims of historic title extending well beyond those that may have been
anticipated when the Convention was concluded in 1982.
2.

The Merits of the Philippines’ Submissions No. 1 and 2230. Having determined that it has jurisdiction to consider the Philippines’ Submissions No. 1 and 2,
the Tribunal now turns to the merits of those claims.
231. Building on prior international law and the 1958 Conventions on the Law of the Sea, theConvention establishes limits for maritime entitlements and sets out the rights and obligations ofcoastal States—as well as other States—within such maritime zones. Articles 2 through 32 of
the Convention govern the rights and obligations of States within the territorial sea and limit theextent of the territorial sea to 12 nautical miles. Articles 55 through 75 of the Convention
provide for the creation of an exclusive economic zone and limit its extent to 200 nautical miles.
Articles 76 to 85 of the Convention govern the rights and obligations of States to the continental
shelf, generally limit the continental shelf to 200 nautical miles, and set out technical criteria
according to which some States may claim a continental shelf beyond 200 nautical miles.
Articles 86 through 120 and 133 through 191 of the Convention govern the rights andobligations of States in the high seas and in the Area of seabed beyond the limits of national
jurisdiction.

The Convention thus provides—and defines limits within—a comprehensive

system of maritime zones that is capable of encompassing any area of sea or seabed.

The South China Sea Arbitration
Award of 12 July 2016232. The Tribunal has already indicated that it understands, on the basis of China’s actions, that
China claims historic rights to the living and non-living resources in the waters of the South
China Sea within the ‘nine-dash line’, but that China does not consider that those waters form
part of its territorial sea or internal waters (other than the territorial sea generated by islands).
Such a claim would not be incompatible with the Convention in any areas where China alreadypossesses such rights through the operation of the Convention. This would, in particular, be thecase within China’s exclusive economic zone and continental shelf. However, to the extent that
China’s claim to historic rights extends to areas that would be considered to form part of theentitlement of the Philippines to an exclusive economic zone or continental shelf, it would be atleast at variance with the Convention.
233. In its Submissions No. 1 and 2, the Philippines requests the Tribunal to declare that China’s
entitlements in the South China Sea are limited to those provided for in the Convention and thatany claim to historic rights, or other sovereign rights and jurisdiction, within the area of the‘nine-dash line’ in excess of that provided for in the Convention is prohibited.
234. China’s claims to rights and jurisdiction within the ‘nine-dash line’ and the Philippines’
Submissions on this dispute raise three issues that are related, but distinct:(a)First, does the Convention, and in particular its rules for the exclusive economic zone andcontinental shelf, allow for the preservation of rights to living and non-living resourcesthat are at variance with the provisions of the Convention and which may have been
established prior to the Convention’s entry into force by agreement or unilateral act?

(b)Second, prior to the entry into force of the Convention, did China have historic rights andjurisdiction over living and non-living resources in the waters of the South China Sea
beyond the limits of the territorial sea?

(c)

Third, and independently of the first two considerations, has China in the years since theconclusion of the Convention established rights and jurisdiction over living andnon-living resources in the waters of the South China Sea that are at variance with theprovisions of the Convention? If so, would such establishment of rights and jurisdiction
be compatible with the Convention?
(a)

The Convention and Prior Claims to Historic Rights and Jurisdiction

235. The Tribunal is faced with the question of whether the Convention allows the preservation ofrights to resources which are at variance with the Convention and established anterior to its
entry into force. To answer this, it is necessary to examine the relationship between the98The South China Sea Arbitration
Award of 12 July 2016

Convention and other possible sources of rights under international law. The relationshipbetween the Convention and other international agreements is set out in Article 311 of theConvention. The Tribunal considers that this provision applies equally to the interaction of theConvention with other norms of international law, such as historic rights, that do not take theform of an agreement. Article 311 provides as follows:
Article 311
Relation to other conventions and international agreements
1.

This Convention shall prevail, as between States Parties, over the Geneva
Conventions on the Law of the Sea of 29 April 1958.

2.

This Convention shall not alter the rights and obligations of States Parties whicharise from other agreements compatible with this Convention and which do notaffect the enjoyment by other States Parties of their rights or the performance of
their obligations under this Convention.

3.

Two or more States Parties may conclude agreements modifying or suspending theoperation of provisions of this Convention, applicable solely to the relations between
them, provided that such agreements do not relate to a provision derogation fromwhich is incompatible with the effective execution of the object and purpose of thisConvention, and provided further that such agreements shall not affect theapplication of the basic principles embodied herein, and that the provisions of suchagreements do not affect the enjoyment by other States Parties of their rights or the
performance of their obligations under this Convention.

4.

States Parties intending to conclude an agreement referred to in paragraph 3 shallnotify the other States Parties through the depositary of this Convention of theirintention to conclude the agreement and of the modification or suspension for which
it provides.

5.

This article does not affect international agreements expressly permitted orpreserved by other articles of this Convention.

6.

States Parties agree that there shall be no amendments to the basic principle relating
to the common heritage of mankind set forth in article 136 and that they shall not beparty to any agreement in derogation thereof.

236. The relationship between the Convention and other rules of international law is also made clear
in Article 293(1) of the Convention, which applies to dispute resolution—including theseproceedings—and provides that “[a] court or tribunal having jurisdiction under this section shallapply this Convention and other rules of international law not incompatible with thisConvention.”
237. These provisions mirror the general rules of international law concerning the interaction ofdifferent bodies of law, which provide that the intent of the parties to a convention will control
its relationship with other instruments. This can be seen, in the case of conflicts between
treaties, in Article 30 of the Vienna Convention on the Law of Treaties. Articles 30(2) and30(3) of the Vienna Convention provide that, as between treaties, the later treaty will prevail to

99

The South China Sea Arbitration
Award of 12 July 2016

the extent of any incompatibility, unless either treaty specifies that it is subject to the other, inwhich case the intent of the parties will prevail.
238. In the case of the Convention, the application of these rules leads to four propositions:(a)Where the Convention expressly permits or preserves other international agreements,
Article 311(5) provides that such agreements shall remain unaffected. The Tribunal
considers that this provision applies equally where historic rights, which may not strictly
take the form of an agreement, are expressly permitted or preserved, such as inArticles 10 and 15, which expressly refer to historic bays and historic titles.

(b)

Where the Convention does not expressly permit or preserve a prior agreement, rule ofcustomary international law, or historic right, such prior norms will not be incompatible
with the Convention where their operation does not conflict with any provision of theConvention or to the extent that interpretation indicates that the Convention intended theprior agreements, rules, or rights to continue in operation.

(c)

Where rights and obligations arising independently of the Convention are notincompatible with its provisions, Article 311(2) provides that their operation will remain
unaltered.

(d)Where independent rights and obligations have arisen prior to the entry into force of theConvention and are incompatible with its provisions, the principles set out in
Article 30(3) of the Vienna Convention and Article 293 of the Convention provide that
the Convention will prevail over the earlier, incompatible rights or obligations.

239. No article of the Convention expressly provides for or permits the continued existence ofhistoric rights to the living or non-living resources of the exclusive economic zone. Similarly,
nothing in the Convention expressly provides for or permits a State to maintain historic rights
over the living and non-living resources of the continental shelf, the high seas, or the Area. The
question for the Tribunal is therefore whether the Convention nevertheless intended thecontinued operation of such historic rights, such that China’s claims should be considered notincompatible with the Convention.
i.

The Text and Context of the Convention

240. Within the exclusive economic zone, Article 56(1) of the Convention provides for the sovereign
rights and jurisdiction of the coastal State in the following terms:

100The South China Sea Arbitration
Award of 12 July 2016

Article 56
Rights, jurisdiction and duties of the coastal State in the exclusive economic zone
1.

In the exclusive economic zone, the coastal State has:(a)sovereign rights for the purpose of exploring and exploiting, conserving andmanaging the natural resources, whether living or non-living, of the waters
superjacent to the seabed and of the seabed and its subsoil, and with regard toother activities for the economic exploitation and exploration of the zone,such as the production of energy from the water, currents and winds;(b)jurisdiction as provided for in the relevant provisions of this Convention withregard to:

(c)

(i)

the establishment and use of artificial islands, installations andstructures;(ii)marine scientific research;(iii)

the protection and preservation of the marine environment;

other rights and duties provided for in this Convention.

241. The rights of other States in the exclusive economic zone are then set out in Article 58, which
limits them to navigation, overflight, and the laying of submarine cables and pipelines, and otherinternationally lawful uses of the sea related to these freedoms. High seas rights and freedoms
apply in the exclusive economic zone only to the extent they are not incompatible with theprovisions of this part of the Convention. Article 58 of the Convention provides as follows:
Article 58
Rights and duties of other States in the exclusive economic zone
1.

In the exclusive economic zone, all States, whether coastal or land-locked, enjoy,
subject to the relevant provisions of this Convention, the freedoms referred to inarticle 87 of navigation and overflight and of the laying of submarine cables andpipelines, and other internationally lawful uses of the sea related to these freedoms,
such as those associated with the operation of ships, aircraft and submarine cables
and pipelines, and compatible with the other provisions of this Convention.

2.

Articles 88 to 115 and other pertinent rules of international law apply to the
exclusive economic zone in so far as they are not incompatible with this Part.

3.

In exercising their rights and performing their duties under this Convention in the
exclusive economic zone, States shall have due regard to the rights and duties of thecoastal State and shall comply with the laws and regulations adopted by the coastal
State in accordance with the provisions of this Convention and other rules ofinternational law in so far as they are not incompatible with this Part.

242. Finally, the rights of other States “whose nationals have habitually fished in the zone” arespecifically addressed in Article 62 of the Convention. Under this provision, coastal States are
only obliged to permit fishing in the exclusive economic zone by foreign nationals in the eventthat the coastal State lacks the capacity to harvest the entire allowable catch. Even then, historicfishing in the area is only one of the criteria to be applied in allocating access, and foreign101The South China Sea Arbitration
Award of 12 July 2016

fishing is subject to the laws and regulation of the coastal State. Article 62 of the Convention
provides in relevant part as follows:
Article 62
Utilization of the living resources
1.

The coastal State shall promote the objective of optimum utilization of the living
resources in the exclusive economic zone without prejudice to article 61.

2.

The coastal State shall determine its capacity to harvest the living resources of the
exclusive economic zone. Where the coastal State does not have the capacity toharvest the entire allowable catch, it shall, through agreements or other arrangements
and pursuant to the terms, conditions, laws and regulations referred to inparagraph 4, give other States access to the surplus of the allowable catch, having
particular regard to the provisions of articles 69 and 70, especially in relation to thedeveloping States mentioned therein.

3.

In giving access to other States to its exclusive economic zone under this article, thecoastal State shall take into account all relevant factors, including, inter alia, thesignificance of the living resources of the area to the economy of the coastal State
concerned and its other national interests, the provisions of articles 69 and 70, therequirements of developing States in the subregion or region in harvesting part ofthe surplus and the need to minimize economic dislocation in States whose nationals
have habitually fished in the zone or which have made substantial efforts in researchand identification of stocks.

4.

Nationals of other States fishing in the exclusive economic zone shall comply withthe conservation measures and with the other terms and conditions established in thelaws and regulations of the coastal State. These laws and regulations shall beconsistent with this Convention and may relate, inter alia, to the following . . . .

243. As a matter of the text alone, the Tribunal considers that the Convention is clear in according
sovereign rights to the living and non-living resources of the exclusive economic zone to thecoastal State alone. The notion of sovereign rights over living and non-living resources isgenerally incompatible with another State having historic rights to the same resources, inparticular if such historic rights are considered exclusive, as China’s claim to historic rights
appears to be. Furthermore, the Tribunal considers that, as a matter of ordinary interpretation,the (a) express inclusion of an article setting out the rights of other States and (b) attention given
to the rights of other States in the allocation of any excess catch preclude the possibility that theConvention intended for other States to have rights in the exclusive economic zone in excess of
those specified.
244. The same considerations apply with respect to the sovereign rights of the continental shelf,
which are set out in Article 77 of the Convention. On the continental shelf, the rights of otherStates are limited to laying cables and pipelines and to the rights and freedoms to which they areotherwise entitled in the superjacent waters.

Indeed, the provisions of the Convention

concerning the continental shelf are even more explicit that rights to the living and non-living
resources pertain to the coastal State exclusively. Article 77(2) expressly provides that “[t]herights referred to in paragraph 1 [relating to natural resources] are exclusive in the sense that if
102

The South China Sea Arbitration
Award of 12 July 2016

the coastal State does not explore the continental shelf or exploit its natural resources, no one
may undertake these activities without the express consent of the coastal State.” Article 81
similarly states that “[t]he coastal State shall have the exclusive right to authorize and regulate
drilling on the continental shelf for all purposes.”245. Moving from the text to the context of exclusive economic zone rights, the Tribunal recalls its
earlier observation (see paragraph 231 above) that the system of maritime zones created by theConvention was intended to be comprehensive and to cover any area of sea or seabed. The
same intention for the Convention to provide a complete basis for the rights and duties of theStates Parties is apparent in the Preamble, which notes the intention to settle “all issues relating
to the law of the sea” and emphasises the desirability of establishing “a legal order for the seas.”
The same objective of limiting exceptions to the Convention to the greatest extent possible isalso evident in Article 309, which provides that “[n]o reservations or exceptions may be madeto this Convention unless expressly permitted by other articles of this Convention.”
246. China has stated its view that its “relevant rights in the South China Sea, formed in the long
historical course” are “protected under international law including the United Nations
Convention on the Law of the Sea (UNCLOS).”233 Insofar as China’s relevant rights comprise aclaim to historic rights to living and non-living resources within the ‘nine-dash line’, partially inareas that would otherwise comprise the exclusive economic zone or continental shelf of thePhilippines, the Tribunal cannot agree with this position. The Convention does not include any
express provisions preserving or protecting historic rights that are at variance with theConvention. On the contrary, the Convention supersedes earlier rights and agreements to theextent of any incompatibility. The Convention is comprehensive in setting out the nature of the
exclusive economic zone and continental shelf and the rights of other States within those zones.
China’s claim to historic rights is not compatible with these provisions.
247. The Tribunal considers the text and context of the Convention to be clear in superseding any
historic rights that a State may once have had in the areas that now form part of the exclusive
economic zone and continental shelf of another State. There is no ambiguity here that would
call for the Tribunal to have recourse to the supplementary means of interpretation set out in
Article 32 of the Vienna Convention. Nevertheless, in light of the sensitivity of the matters at
issue in these proceedings, the Tribunal considers it warranted to recall the origin of and purpose
behind the Convention’s provisions on the exclusive economic zone and continental shelf.

ii.

The Negotiation of the Convention and the Creation of the Exclusive
Economic Zone

248. The Tribunal recalls that prior to the adoption of the Convention, the principal failure of theFirst and Second UN Conferences on the Law of the Sea was the lack of agreement on thebreadth of the territorial sea and the extent of coastal States’ jurisdiction over the resources, thenprincipally involving fisheries, of the waters adjacent to their coasts. This period coincided withthe widespread decolonisation of developing States, and many newly independent governmentssought to secure greater control over the waters adjacent to their coasts. The lack of agreement
on an international standard and the growing capabilities of the long-distance fishing fleets ofdeveloped States led to the widespread unilateral declaration of exclusive fishing zones ofvarying breadths and to the declaration, by some States, of a 200-nautical-mile territorial sea.
Such claims to zones, including the Icelandic exclusive fishing zones considered by theInternational Court of Justice in the Fisheries Jurisdiction cases,234 were generally opposed by
the traditional maritime States, which sought to limit the scope of national jurisdiction.
249. The creation of the Ad Hoc and Permanent Seabed Committees that preceded the Third UN
Conference on the Law of the Sea was prompted by concern with this unregulated propagationof claims to maritime rights and jurisdiction and with the prospect that technologicaldevelopments would rapidly enable the greater exploitation of the resources of the seabed,which would fall to those States most capable of claiming them.235 Latin American and African
States organised around an assertion of greater control over coastal resources 236 and draft
articles on the concept of an exclusive economic zone were introduced by Kenya during the1972 session of the Seabed Committee.237 In this form, the exclusive economic zone was acompromise proposal: a standardised form of coastal State jurisdiction—exclusive if the coastal
State so desired—over living and non-living resources that nevertheless stopped short ofextending the territorial sea beyond 12 nautical miles.

104

The South China Sea Arbitration
Award of 12 July 2016250. The Tribunal recalls this history because it frames the debates that took place during thenegotiation of the Convention. Japan and the Soviet Union possessed the largest distant sea
fishing fleets and sought to preserve the status quo, advancing proposals that would haveprovided only for “preferential rights” for coastal States, while protecting the position of
traditional fishing States. As summarised by Japan:
While according a preferential right of catch to developing coastal States corresponding totheir harvesting capacities and a differentiated preferential right to developed coastal States,
the proposals also take into consideration the legitimate interests of other States. Thus, theyseek to ensure that a gradual accommodation of interests can be brought about in the
expanding exploitation and use of fishery resources of the high seas, without causing any
abrupt change in the present order in fishing which might result in disturbing the economic
and social structures of States.238

The Soviet Union, for its part, sought to limit the rights of coastal States to fisheries beyond
12 nautical miles to a preferential right to reserve “such part of the allowable catch of fish as canbe taken by vessels navigating under that State’s flag.” 239 These proposals were ultimately
rejected and are not reflected in the text of the Convention, as adopted.
251. In the course of these debates, China actively positioned itself as one of the foremost defendersof the rights of developing States and was resolutely opposed to any suggestion that coastal
States could be obliged to share the resources of the exclusive economic zone with other powersthat had historically fished in those waters. The Tribunal considers the remarks of Mr. Ling
Ching on behalf of China during the 24th meeting of the Second Committee to be representativeof the committed position that China repeatedly took during the negotiation of the Convention:
On the question whether the coastal State should exercise full sovereignty over the
renewable and non-renewable resources in its economic zone or merely have preferential
rights to them, [Mr. Ling] said that such resources in the off-shore sea areas of a coastal
State were an integral part of its natural resources. The super-Powers had for years
wantonly plundered the offshore resources of developing coastal States, thereby seriously
damaging their interests. Declaration of permanent sovereignty over such resources was a
legitimate right, which should be respected by other countries. The super-Powers,
however, while giving verbal recognition to the economic zone, were advocating theplacing of restrictions on the sovereignty of coastal States over their resources. For
example, one of them had proposed that the coastal State should allow foreign fishermen
the right to fish within that zone in cases where the State did not harvest 100 per cent of theallowable catch. Such logic made no sense. The suggestion in fact harked back to thatsuper-Power’s well-known proposal that coastal States should be allowed only “preferential
rights” when fishing their own off-shore areas. Yet, the establishment of exclusive

105

economic zones over the resources of which coastal States would exercise permanent
sovereignty simply meant that the developing countries were regaining their long-lost rights
and in no way implied a sacrifice on the part of the super-Powers. The coastal State shouldbe permitted to decide whether foreign fishermen were allowed to fish in the areas under its
jurisdiction by virtue of bilateral or regional agreements, but it should not be obliged to
grant other States any such rights.240

252. The Tribunal notes these comments not because the remarks of any particular State during thenegotiation of a multilateral Convention are indicative of the content of the final treaty, but
because China’s resolute opposition to any accommodation of historic fishing is largely
representative of the position that prevailed in the final text of the Convention. The Tribunal
also notes that China’s position, as asserted during the negotiation of the Convention, is
incompatible with a claim that China would be entitled to historic rights to living and non-living
resources in the South China Sea that would take precedence over the exclusive economic zone
rights of the other littoral States. China never advanced such a claim during the course of thenegotiations, notwithstanding that the South China Sea and the question of sovereignty over the
Spratly Islands was raised on several occasions in exchanges between China and the Philippines
during the work of the Seabed Committee241 and between China and Viet Nam during the Third
UN Conference.242

253. The Tribunal also considers the negotiating history of the Convention instructive for the light it
sheds on the intent for the Convention to serve as a comprehensive text and the importance tothat goal of the prohibition on reservations enshrined in Article 309. The Convention was
negotiated on the basis of consensus and the final text represented a package deal.

A

prohibition on reservations was seen as essential to prevent States from clawing back throughreservations those portions of the final compromise that they had opposed in negotiations. In
this respect the Convention follows the practice of other multilateral treaties considered to be offundamental importance, including the UN Charter, the Rome Statute of the International
Criminal Court, and the UN Framework Convention on Climate Change. The importance of acomprehensive agreement, without reservations, is well expressed in the Conference President’s
remarks to the Informal Plenary and Group of Legal Experts tasked with preparing the final
clauses:
Our prime concern is the establishment of a completely integrated legal order for the use of
the oceans and its resources and potential. All else must be subordinated to and subserve
this purpose. This is the function of the Preamble and the Final Clauses. They must not beallowed to create such contention as would obscure and obstruct the overriding objective,
hamper the work of the Conference and imperil our chances of success.
We must seek to preserve intact, and protect, the efficacy and durability of the body of law
which we are trying to create in the form of a Convention encompassing all issues andproblems relating to the law of the sea as a package comprising certain elements that
constitute a single and indivisible entity.
We must seek to attract the most extensive and representative degree of ratification and theearliest possible entry into force of the new Convention.
The second objective that I have specified here cannot be achieved if we expose theessential unity and coherence of the new body of law to the danger of impairment throughthe unrestricted exercise of the right of reservation.243

254. On this issue, the Tribunal notes that China and other States were opposed to a complete ban onreservations244 and that the final approach in the Convention represents a compromise: certain
permissible reservations are set out in the text of the Convention while any other reservation isprohibited. Thus China was entitled to, and did, activate the reservations to compulsory disputesettlement in Article 298—that the Tribunal has already determined do not apply to the present
dispute—but is not entitled to except itself from the system of compulsory settlement

generally. 245 In the Tribunal’s view, the prohibition on reservations is informative of theConvention’s approach to historic rights. It is simply inconceivable that the drafters of theConvention could have gone to such lengths to forge a consensus text and to prohibit any but a
few express reservations while, at the same time, anticipating that the resulting Convention
would be subordinate to broad claims of historic rights.
iii.

Rights in the Exclusive Economic Zone in other Disputes concerning theLaw of the Sea

255. The present dispute is not the first instance in which a State has claimed rights in or to the
exclusive economic zone of a neighbouring State. The Tribunal considers it useful, for the
purpose of confirming its own reasoning, to briefly canvas the other decisions to have addressedclaims involving rights in the exclusive economic zone of another State.
256. In the Tribunal’s view, the most relevant instance occurs in the consideration given to historicfishing activities in the delimitation of the Gulf of Maine between the United States and Canada
by a chamber of the International Court of Justice. The area to be delimited included theGeorges Bank, with its abundant fisheries resources, and the United States argued that thedelimitation line should take account of the longstanding use of the bank by U.S. fishermen.
The Chamber not only rejected this argument for the purposes of the delimitation, but went on
to comment on the nature of U.S. fishing rights and the effect on U.S. fishing activities of the
adoption by the United States and Canada of exclusive fisheries zones, the case having been
instituted prior to the declaration of a full exclusive economic zone by the United States but at atime when States had already begun to declare such zones unilaterally in reflection of theemerging consensus at the Third UN Conference. In this context, the Chamber in Gulf of Maine
commented as follows:
The Chamber cannot adopt these positions of the Parties. Concerning that of the UnitedStates, it can only confirm its decision not to ascribe any decisive weight, for the purposesof the delimitation it is charged to carry out, to the antiquity or continuity of fishingactivities carried on in the past within that part of the delimitation area which lies outside
the closing line of the Gulf. Until very recently, as the Chamber has recalled, these
expanses were part of the high seas and as such freely open to the fishermen not only of theUnited States and Canada but also of other countries, and they were indeed fished by very
many nationals of the latter. The Chamber of course readily allows that, during that periodof free competition, the United States, as the coastal State, may have been able at certain
places and times—no matter for how long—to achieve an actual predominance for its
fisheries. But after the coastal States had set up exclusive 200-mile fishery zones, thesituation radically altered. Third States and their nationals found themselves deprived ofany right of access to the sea areas within those zones and of any position of advantage theymight have been able to achieve within them. As for the United States, any mere factual
predominance which it had been able to secure in the area was transformed into a situation
245

See Award on Jurisdiction, para. 107.

108

The South China Sea Arbitration
Award of 12 July 2016of legal monopoly to the extent that the localities in question became legally part of its own
exclusive fishery zone. Conversely, to the extent that they had become part of the exclusive
fishery zone of the neighbouring State, no reliance could any longer be placed on that
predominance. Clearly, whatever preferential situation the United States may previously
have enjoyed, this cannot constitute in itself a valid ground for its now claiming theincorporation into its own exclusive fishery zone of any area which, in law, has become
part of Canada’s.246

257. The present case does not, of course, involve delimitation, but the Tribunal considers the
Chamber’s views on the effect of exclusive fisheries zones, declared as a matter of customarylaw, to confirm its own interpretation of the provisions of the Convention. The Tribunal has no
doubt that Chinese fisherman have long made use of the waters of the South China Sea,
including in areas beyond the territorial sea of any feature. If China had historic rights giving ita privileged position with respect to the resources of such waters, the acceptance of the
exclusive economic zone as a matter of customary law and China’s adherence to the Convention
altered that situation. Through the Convention, China gained additional rights in the areas
adjacent to its coasts that became part of its exclusive economic zone, including the areas
adjacent to any island entitled to such a zone. It necessarily follows, however, that China also
relinquished the rights it may have held in the waters allocated by the Convention to the
exclusive economic zones of other States.
258. A contrary indication could be ascribed to the decision of the International Court of Justice in
the Fisheries Jurisdiction Cases.247 In those disputes, which concerned Iceland’s declaration of
a 50-nautical-mile exclusive fishing zone, the Court held that the preferential rights asserted by
Iceland’s fishing zone were not compatible with the exclusion of all fishing by other States andthat Iceland could not extinguish the rights of other States to have habitually fished in thearea.248 In the Tribunal’s view, however, this decision from 1974 must be understood in thecontext of the law of the sea as it then was, which differs from the law prevailing under theConvention or in the emergent customary law of the exclusive economic zone in effect at thetime of Gulf of Maine. As an initial matter, the Tribunal notes that the applicants in Fisheries
Jurisdiction, the United Kingdom and the Federal Republic of Germany, never asserted that
their historical fishing superseded Iceland’s declaration of a fisheries zone, but merely claimed aright of access. This thus differs fundamentally from the present proceedings, where the
Tribunal understands China to consider that its claimed historic rights to living and non-living

resources effectively negate the exclusive economic zone rights of other littoral States to theSouth China Sea. Notwithstanding this difference, the Tribunal also considers the reasoning
exhibited in Fisheries Jurisdiction to be inapplicable under the present law of the sea. At thetime Iceland declared its 50-nautical-mile zone in July 1972, the extension of national
jurisdiction over maritime areas beyond the territorial sea was still a hotly contested issue. As
the Court read the state of customary law then prevailing, it permitted an exclusive fishing zoneof only 12 nautical miles and preferential rights in an undefined area beyond that limit.249 Onlya few short years later, however, the processes at work in the Third UN Conference (describedabove at paragraph 249 to 252) crystallised into the consensus in favour of the exclusive
economic zone. The law applied in Gulf of Maine and recorded in the Convention thus differedmaterially from that considered by the Court in Fisheries Jurisdiction.
259. A contrary approach to Gulf of Maine might also be identified in the Eritrea v. Yemen
arbitration, in which the arbitral tribunal emphasised the importance of preserving traditional
fishing practices in the Red Sea which had been carried on for centuries, without regard for the
specifics of maritime boundaries. The arbitral tribunal also held that “[t]he traditional fishingregime is not limited to the territorial waters of specified islands” but extended also through theexclusive economic zone of Eritrea and Yemen. 250

The Philippines distinguishes thisdecision —correctly in the Tribunal’s view—on the basis of applicable law. Eritrea v. Yemen
251

was not an arbitration under Annex VII to the Convention and that arbitral tribunal was notbound by Article 293 to apply only the Convention and rules of law not incompatible therewith.
Instead, the Parties’ arbitration agreement empowered the arbitral tribunal, in the second stageof the proceedings to render its decision “taking into account the opinion that it will haveformed on questions of territorial sovereignty, the United Nations Convention on the Law of theSea, and any other pertinent factor.” 252 The arbitral tribunal in Eritrea v. Yemen was thus
empowered to—and in the Tribunal’s view did—go beyond the law on traditional fishing as it
would exist under the Convention. The Tribunal will address below the scope of traditional
fishing rights under the current law of the sea in connection with the Philippines’ Submission
No. 10.

The South China Sea Arbitration
Award of 12 July 2016260. Finally, the Tribunal notes that the arbitral tribunal in the Chagos Marine Protected Area
Arbitration held that Mauritius had rights in the exclusive economic zone declared by theUnited Kingdom surrounding the British Indian Ocean Territory. These were not fishing rights,
in light of the Convention’s prohibition in Article 297 on compulsory settlement regarding
disputes over sovereign rights with respect to the living resources in the exclusive economic
zone, but rather a right to the eventual return of the Chagos Archipelago when no longer neededfor defence purposes and a right to the benefit of any oil or minerals discovered in or near the
Chagos Archipelago. These rights had their origins in assurances given in 1968 in connection
with the detachment of the Chagos Archipelago from the then-colony of Mauritius that wererepeated by the United Kingdom thereafter. In that case, however, not only did the United
Kingdom not argue that Mauritius’s rights were extinguished by the United Kingdom’s
declaration of an Environmental Protection and Preservation Zone/Fisheries Conservation andManagement Zone, but it reiterated its undertakings thereafter253 and emphasised that the zone it
had created was not an exclusive economic zone for purposes beyond fisheries andenvironmental protection.254 Article 311 permits States to agree to modify certain aspects of theConvention as between them (an issue the Tribunal will return to below) and the Tribunal
considers the United Kingdom’s reiteration of its undertakings following the adoption of theConvention to fall within the ambit of that provision.
*
261. For all of the reasons discussed above, the Tribunal concludes that China’s claim to historicrights to the living and non-living resources within the ‘nine-dash line’ is incompatible with theConvention to the extent that it exceeds the limits of China’s maritime zones as provided for by
the Convention.

This is apparent in the text of the Convention which comprehensively

addresses the rights of other States within the areas of the exclusive economic zone andcontinental shelf and leaves no space for an assertion of historic rights. It is also reinforced by
the negotiating record of the Convention where the importance of adopting a comprehensive
instrument was manifest and where the cause of securing the rights of developing States overtheir exclusive economic zone and continental shelf was championed, in particular, by China.
262. Accordingly, upon China’s accession to the Convention and its entry into force, any historicrights that China may have had to the living and non-living resources within the ‘nine-dash line’
were superseded, as a matter of law and as between the Philippines and China, by the limits ofthe maritime zones provided for by the Convention. This should not be considered exceptional

or unexpected. The Convention was a package that did not, and could not, fully reflect any
State’s prior understanding of its maritime rights. Accession to the Convention reflects a
commitment to bring incompatible claims into alignment with its provisions, and its continued
operation necessarily calls for compromise by those States with prior claims in excess of theConvention’s limits.
(b)

China’s Claim to Historic Rights in the South China Sea

263. The Tribunal has held, in the preceding Section, that the entry into force of the Convention had
the effect of superseding any claim by China to historic rights to the living and non-living
resources within the ‘nine-dash line’ beyond the limits of China’s maritime zones as provided
for by the Convention. This conclusion would, in one sense, suffice to decide the disputepresented by the Philippines’ Submissions No. 1 and 2. The Tribunal nevertheless considers it
important, for the sake of completeness, to distinguish among China’s claims to historic rights
and to separate those that are, in fact, in excess of and incompatible with the Convention, fromthose that are not. The Tribunal considers that, in ratifying the Convention, China has, in fact,
relinquished far less in terms of its claim to historic rights than the foregoing conclusion might
initially suggest.

The Tribunal also considers that this is an area where communications

between the Parties have been characterised by a high degree of confusion andmisunderstanding.
264. In its public statements, diplomatic correspondence, and in its public Position Paper of7 December 2014, China has repeatedly asserted its sovereignty over the Spratly Islands andScarborough Shoal.255 According to China, its nationals have historically engaged in navigationand trade in the South China Sea and the activities of Chinese fishermen in residing, working,and living among the Spratly Islands “are all manifestly recorded in Geng Lu Bu (Manual of
Sea Routes) which was passed down from generation to generation among Chinese
fishermen.” 256 There is, indeed, much interesting evidence—from all sides—that could beconsidered by a tribunal empowered to address the question of sovereignty over the Spratly
Islands and Scarborough Shoal. This Tribunal, however, is not empowered to address thatquestion. For its part, the Philippines has likewise argued about the historical limits of China’s
land territory, the degree of China’s historical commitment to oceangoing trade and navigation,

112

and China’s historical knowledge concerning the Spratly Islands.

In the Tribunal’s view,

however, much of this evidence—on both sides—has nothing to do with the question of whether
China has historically had rights to living and non-living resources beyond the limits of theterritorial sea in the South China Sea and therefore is irrelevant to the matters before thisTribunal.
265. The Tribunal recalls that the process for the formation of historic rights in international law iswell summarised in the UN Secretariat’s 1962 Memorandum on the Juridical Regime ofHistoric Waters, Including Historic Bays and requires the continuous exercise of the claimed
right by the State asserting the claim and acquiescence on the part of other affected States.
Although that memorandum discussed the formation of rights to sovereignty over historicwaters, as the Tribunal noted above (see paragraph 225), historic waters are merely one form ofhistoric right and the process is the same for claims to rights short of sovereignty.
266. Accordingly, the scope of a claim to historic rights depends upon the scope of the acts that are
carried out as the exercise of the claimed right. Evidence that either the Philippines or China
had historically made use of the islands of the South China Sea would, at most, support a claim
to historic rights to those islands. Evidence of use giving rise to historic rights with respect tothe islands, however, would not establish historic rights to the waters beyond the territorial sea.
The converse is also true: historic usage of the waters of the South China Sea cannot lead torights with respect to the islands there. The two domains are distinct.
267. Because the Tribunal is not addressing questions of sovereignty, evidence concerning either
Party’s historical use of the islands of the South China Sea is of no interest with respect to theformation of historic rights (although, as will be discussed below (see paragraphs 549 to 551), it
may bear upon the status of features pursuant to Article 121(3)). The Tribunal does find it
relevant, however, to consider what would be required for it to find that China did have historic
maritime rights to the living and non-living resources within the ‘nine-dash line’.
268. On this issue, the Tribunal notes that historic rights are, in most instances, exceptional rights.
They accord a right that a State would not otherwise hold, were it not for the operation of thehistorical process giving rise to the right and the acquiescence of other States in the process. It
follows from this, however, that the exercise of freedoms permitted under international law
cannot give rise to a historic right; it involves nothing that would call for the acquiescence ofother States and can only represent the use of what international law already freely permits.
269. Prior to the introduction of the Convention system—and certainly prior to the Second World
War—the international legal regime for the oceans recognised only a narrow belt of territorial
113

The South China Sea Arbitration
Award of 12 July 2016sea and the vast areas of high seas that comprised (and still comprise) the majority of theoceans. Under this regime, nearly all of the South China Sea formed part of the high seas, andindeed China’s Declaration of the Government of the People’s Republic of China on China’s
Territorial Sea of 4 September 1958 expressly recognises that it applies to “the Dongsha
Islands, the Xisha Islands, the Zhongsha Islands, the Nansha Islands and all other islands
belonging to China which are separated from the mainland and its coastal islands by the highseas.”257 For much of history, therefore, China’s navigation and trade in the South China Sea,
as well as fishing beyond the territorial sea, represented the exercise of high seas freedoms.
China engaged in activities that were permitted to all States by international law, as did thePhilippines and other littoral States surrounding the South China Sea. Before the Second World
War, the use of the seabed, beyond the limits of the territorial sea, was likewise a freedom open
to any State that wished to do so, although as a practical matter the technological ability to do so
effectively has emerged only more recently.
270. Historical navigation and fishing, beyond the territorial sea, cannot therefore form the basis forthe emergence of a historic right. As the Chamber in Gulf of Maine recognised with respect tohistoric U.S. fishing on the Georges Bank, such activity was merely the exercise of freedoms
already permitted by international law. 258 Evidence that merely points to even very intensive
Chinese navigation and fishing in the South China Sea would be insufficient. Instead, in orderto establish historic rights in the waters of the South China Sea, it would be necessary to showthat China had engaged in activities that deviated from what was permitted under the freedom of
the high seas and that other States acquiesced in such a right. In practice, to establish theexclusive historic right to living and non-living resources within the ‘nine-dash line’, which
China now appears to claim, it would be necessary to show that China had historically sought toprohibit or restrict the exploitation of such resources by the nationals of other States and thatthose States had acquiesced in such restrictions. In the Tribunal’s view, such a claim cannot be
supported. The Tribunal is unable to identify any evidence that would suggest that China
historically regulated or controlled fishing in the South China Sea, beyond the limits of theterritorial sea. With respect to the non-living resources of the seabed, the Tribunal does noteven see how this would be theoretically possible. Seabed mining was a glimmer of an idea
when the Seabed Committee began the negotiations that led to the Convention. Offshore oil
extraction was in its infancy and only recently became possible in deep water areas. Indeed, the257

The South China Sea Arbitration
Award of 12 July 2016

China National Offshore Oil Corporation itself was only founded in 1982, the same year that
China signed the Convention. With respect to the seabed, the Tribunal does not see any
historical activity that could have been restricted or controlled, and correspondingly no basis fora historic right.
271. Accordingly, in the Tribunal’s view, China’s ratification of the Convention in June 1996 did not
extinguish historic rights in the waters of the South China Sea. Rather, China relinquished thefreedoms of the high seas that it had previously utilised with respect to the living and non-living
resources of certain sea areas which the international community had collectively determined toplace within the ambit of the exclusive economic zone of other States. At the same time, China
gained a greater degree of control over the maritime zones adjacent to and projecting from its
coasts and islands. China’s freedom to navigate the South China Sea remains unaffected.
272. Finally, because the Tribunal considers the question of historic rights with respect to maritime
areas to be entirely distinct from that of historic rights to land, the Tribunal considers it opportune
to note that certain claims remain unaffected by this decision. In particular, the Tribunal
emphasises that nothing in this Award should be understood to comment in any way on China’s
historic claim to the islands of the South China Sea. Nor does the Tribunal’s decision that aclaim of historic rights to living and non-living resources is not compatible with the Convention
limit China’s ability to claim maritime zones in accordance with the Convention, on the basis ofsuch islands. The Tribunal will address the question of the entitlements that can be generated
by different features in the South China Sea in the following Chapter.
(c)

Whether China has Established Exceptional Rights or Jurisdiction since the
Adoption of the Convention

273. As a final matter, and for the sake of completeness, the Tribunal considers it appropriate tobriefly address whether China has acquired rights or jurisdiction at variance with theConvention in the years since the Convention entered into force in 1996.
274. Paragraphs 3 and 4 of Article 311 of the Convention permit States to agree between them tomodify the operation of the Convention between them, provided that such agreements arenotified to other States Parties, do not affect the rights of other States, and are in keeping withthe object and purpose of the Convention:
3.

Two or more States Parties may conclude agreements modifying or suspending theoperation of provisions of this Convention, applicable solely to the relations between
them, provided that such agreements do not relate to a provision derogation fromwhich is incompatible with the effective execution of the object and purpose of thisConvention, and provided further that such agreements shall not affect theapplication of the basic principles embodied herein, and that the provisions of such

115

The South China Sea Arbitration
Award of 12 July 2016agreements do not affect the enjoyment by other States Parties of their rights or the
performance of their obligations under this Convention.
4.

States Parties intending to conclude an agreement referred to in paragraph 3 shallnotify the other States Parties through the depositary of this Convention of theirintention to conclude the agreement and of the modification or suspension for which
it provides.

Similarly, the subsequent practice of the States parties may bear on the interpretation of a treaty
pursuant to Article 31 of the Vienna Convention, or a new rule of customary international law
may emerge to modify the provisions of a treaty. International law is not static.
275. The Tribunal does not consider it necessary here to address in general whether and under which
conditions the Convention may be modified by State practice.259 It is sufficient to say that a
unilateral act alone is not sufficient. Such a claim would require the same elements discussed
above with respect to historic rights: the assertion by a State of a right at variance with theConvention, acquiescence therein by the other States Parties, and the passage of sufficient timeto establish beyond doubt the existence of both the right and a general acquiescence. Here,however, there is no basis for such a claim. Since the adoption of the Convention, historicrights were mentioned in China’s Exclusive Economic Zone and Continental Shelf Act,260 but
without anything that would enable another State to know the nature or extent of the rights
claimed. The extent of the rights asserted within the ‘nine-dash line’ only became clear with
China’s Notes Verbales of May 2009. Since that date, China’s claims have been clearlyobjected to by other States. In the Tribunal’s view, there is no acquiescence.
(d)Conclusion

276. The Philippines’ Submissions No. 1 and 2 are linked and represent two aspects of one disputeconcerning the source of maritime rights and entitlements in the South China Sea.
277. With respect to Submission No. 1, for the reasons set out above, the Tribunal concludes that, as
between the Philippines and China, the Convention defines the scope of maritime entitlementsin the South China Sea, which may not extend beyond the limits imposed therein.

259

The Tribunal will address the role of State practice in the interpretation of the Convention, in accordancewith Article 31 of the Vienna Convention on the Law of Treaties, in relation to the interpretation of

THE STATUS OF FEATURES IN THE SOUTH CHINA SEA (SUBMISSIONS
NO. 3 TO 7)A.

INTRODUCTION

279. In this Chapter, the Tribunal assesses the status of certain maritime features and the entitlements
to maritime zones that they are capable of generating for the purposes of the Convention.
280. In the terminology of the Convention, a feature that is exposed at low tide but covered withwater at high tide is referred to as a ‘low-tide elevation’. Features that are above water at hightide are referred to generically as ‘islands’. However, the entitlements that an island cangenerate to maritime zones will depend upon the application of Article 121(3) of theConvention and whether the island has the capacity to “sustain human habitation or economic
life of [its] own.” Throughout this Chapter, the Tribunal will refer to the generic category offeatures that meet the definition of an island in Article 121(1) as ‘high-tide features’. The
Tribunal will use the term ‘rocks’ for high-tide features that “cannot sustain human habitation or
economic life of their own” and which therefore, pursuant to Article 121(3), are disqualified
from generating an exclusive economic zone or continental shelf. For high-tide features which
are not rocks, and which pursuant to Article 121(2) enjoy the same entitlements as other land
territory under the Convention, the Tribunal will use the term ‘fully entitled islands’. ‘Rocks’
and ‘fully entitled islands’ are thus both sub-sets of the broader category of ‘high-tide features’.
Finally, the Tribunal will refer to features that are fully submerged, even at low tide, as‘submerged features’.

Introduction

281. In this Section, the Tribunal addresses the Parties’ dispute concerning the status of the maritime
features and the source of maritime entitlements in the South China Sea. This dispute isreflected in the Philippines’ Submissions No. 4 and 6, which request the Tribunal to hold thatcertain specified features are low-tide elevations and do not generate any independent
entitlement to maritime zones. Submissions No. 4 and 6 provide as follows:(4)

Mischief Reef, Second Thomas Shoal and Subi Reef are low-tide elevations that do
not generate entitlement to a territorial sea, exclusive economic zone or continental
shelf, and are not features that are capable of appropriation by occupation orotherwise;

...

119

The South China Sea Arbitration
Award of 12 July 2016

(6)

Gaven Reef and McKennan Reef (including Hughes Reef) are low-tide elevations
that do not generate entitlement to a territorial sea, exclusive economic zone orcontinental shelf, but their low-water line may be used to determine the baselinefrom which the breadth of the territorial sea of Namyit and Sin Cowe, respectively,
is measured;

282. The question of whether features are above or below water at high tide is also implicated by thePhilippines’ Submissions No. 3 and 7, which are predicated on the Philippines’ view that
Scarborough Shoal, Johnson Reef, Cuarteron Reef, and Fiery Cross Reef are high-tide featureswith rocks that remain above water at high tide. For the sake of completeness, and in keepingwith its duty under Article 9 of Annex VII to the Convention to satisfy itself that thePhilippines’ Submissions are well founded in fact, the Tribunal will examine the status, as
above or below water at high tide, of all ten features identified in the Philippines’ Submissions.
283. In its Award on Jurisdiction, the Tribunal held that these Submissions reflect a disputeconcerning the status of maritime features in the South China Sea and not a dispute concerning
sovereignty over such features. The Tribunal also held that this is not a dispute concerning sea
boundary delimitation, insofar as “the status of a feature as a ‘low-tide elevation’, ‘island’, or a‘rock’ relates to the entitlement to maritime zones generated by that feature, not to thedelimitation of such entitlements in the event that they overlap.” 261 The Tribunal noted,
however, that the possible existence of overlapping entitlements to an exclusive economic zone
or continental shelf could have “practical considerations for the selection of the vertical datum
and tidal model against which the status of the features is to be assessed.”262

285. Cuarteron Reef is known as “Huayang Jiao” (华阳礁) in China and “Calderon Reef” in thePhilippines. It is a coral reef located at 08° 51′ 41″ N, 112° 50′ 08″ E and is the easternmost offour maritime features known collectively as the London Reefs that are located on the westernedge of the Spratly Islands. Cuarteron Reef is 245.3 nautical miles from the archipelagic
baseline of the Philippine island of Palawan and 585.3 nautical miles from China’s baseline
point 39 (Dongzhou (2)) adjacent to the island of Hainan. The general location of Cuarteron
Reef, along with the other maritime features in the Spratly Islands, is depicted in Map 3 onpage 125 below.
286. Fiery Cross Reef is known as “Yongshu Jiao” (永暑礁) in China and “Kagitingan Reef” in thePhilippines. It is a coral reef located at 09° 33′ 00″ N, 112° 53′ 25″ E, to the north of Cuarteron
Reef and along the western edge of the Spratly Islands, adjacent to the main shipping routes
through the South China Sea. Fiery Cross Reef is 254.2 nautical miles from the archipelagic
baseline of the Philippine island of Palawan and 547.7 nautical miles from the China’s baseline
point 39 (Dongzhou (2)) adjacent to the island of Hainan.
287. Johnson Reef, McKennan Reef, and Hughes Reef are all coral reefs that form part of the larger
reef formation in the centre of the Spratly Islands known as Union Bank. Union Bank also
includes the high-tide feature of Sin Cowe Island. Johnson Reef (also known as Johnson SouthReef) is known as “Chigua Jiao” (赤瓜礁) in China and “Mabini Reef” in the Philippines. It is
located at 9° 43′ 00″ N, 114° 16′ 55″ E and is 184.7 nautical miles from the archipelagic
baseline of the Philippine island of Palawan and 570.8 nautical miles from China’s baseline
point 39 (Dongzhou (2)) adjacent to Hainan.

Although the Philippines has referred to“McKennan Reef (including Hughes Reef)” in its Submissions, the Tribunal notes that
McKennan Reef and Hughes Reef are distinct features, albeit adjacent to one another, andconsiders it preferable, for the sake of clarity, to address them separately. McKennan Reef isknown as “Ximen Jiao” (西门礁) in China and, with Hughes Reef, is known collectively as“Chigua Reef” in the Philippines. It is located at 09° 54′ 13″ N, 114° 27′ 53″ E and is181.3 nautical miles from the archipelagic baseline of the Philippine island of Palawan and566.8 nautical miles from China’s baseline point 39 (Dongzhou (2)) adjacent to Hainan.
Hughes Reef is known as “Dongmen Jiao” (东门礁) in China and, with McKennan Reef, is
known collectively as “Chigua Reef” in the Philippines.

It is located at 09° 54′ 48″

N 114°29′ 48″ E and is 180.3 nautical miles from the archipelagic baseline of the Philippine
island of Palawan and 567.2 nautical miles from China’s baseline point 39 (Dongzhou (2))
adjacent to Hainan.

288. The Gaven Reefs are known as “Nanxun Jiao” ( 南 薰 礁 ) in China and “Burgos” in thePhilippines. They constitute a pair of coral reefs that forms part of the larger reef formation
known as Tizard Bank, located directly to the north of Union Bank. Tizard Bank also includes
the high-tide features of Itu Aba Island, Namyit Island, and Sand Cay. Gaven Reef (North) is
located at 10° 12′ 27″ N, 114° 13′ 21″ E and is 203.0 nautical miles from the archipelagic
baseline of the Philippine island of Palawan and 544.1 nautical miles from China’s baseline
point 39 (Dongzhou (2)) adjacent to Hainan. Gaven Reef (South) is located at 10° 09′ 42″ N
114° 15′ 09″ E and is 200.5 nautical miles from the archipelagic baseline of the Philippine
island of Palawan and 547.4 nautical miles from China’s baseline point 39 (Dongzhou (2))
adjacent to Hainan.
289. Subi Reef is known as “Zhubi Jiao” (渚碧礁) in China and “Zamora Reef” in the Philippines. It
is a coral reef located to the north of Tizard Bank and a short distance to the south-west of thehigh-tide feature of Thitu Island and its surrounding Thitu Reefs. Subi Reef is located at 10° 55′
22″ N, 114° 05′ 04″ E and lies on the north-western edge of the Spratly Islands. Subi Reef is231.9 nautical miles from the archipelagic baseline of the Philippine island of Palawan and502.2 nautical miles from China’s baseline point 39 (Dongzhou (2)) adjacent to Hainan.
290. Mischief Reef and Second Thomas Shoal are both coral reefs located in the centre of the Spratly
Islands, to the east of Union Bank and to the south-east of Tizard Bank. Mischief Reef isknown as “Meiji Jiao” (美济礁) in China and “Panganiban” in the Philippines. It is located at
09° 54′ 17″ N, 115° 31′ 59″ E and is 125.4 nautical miles from the archipelagic baseline of thePhilippine island of Palawan and 598.1 nautical miles from China’s baseline point 39(Dongzhou (2)) adjacent to Hainan. Second Thomas Shoal is known as “Ren’ai Jiao” (仁爱礁)in China and “Ayungin Shoal” in the Philippines. It is located at 09° 54′ 17″ N, 115° 51′ 49″ E
and is 104.0 nautical miles from the archipelagic baseline of the Philippine island of Palawan
and 616.2 nautical miles from China’s baseline point 39 (Dongzhou (2)) adjacent to Hainan.

The Philippines’ Position

291. The Philippines recalls that low-tide elevations are defined and governed by Article 13 of theConvention.264 “[L]ow-tide elevations are not land territory,” the Philippines emphasises, and“no measure of occupation or control can establish sovereignty over such features.” 265
According to the Philippines, low-tide elevations can be divided into three categories:

The South China Sea Arbitration
Award of 12 July 2016(a)“[W]here a low-tide elevation is located within 12 miles of a high-tide feature,
sovereignty over the low-tide elevation rests with the State by reason of the sovereignty it
has over the high-tide feature.”266(b)Where “low-tide elevations . . . lie wholly beyond 12 miles, but within a state’s exclusive
economic zone or continental shelf . . . , the coastal state enjoys exclusive sovereign
rights and jurisdiction with regard to the low-tide elevation in accordance and within thelimits of the regime provided for in Articles 56(3) and 77 of the 1982 Convention.”267(c)

And where a low-tide elevation would be located “at an even greater distance, beyond
areas of national jurisdiction. In such cases, it is part of the deep seabed and subject toPart XI of the Convention, and no state can purport to exercise sovereignty or any
sovereign rights over or in respect of it.”268

The Philippines also notes that, pursuant to Article 13(1), there is a distinction between low-tide
elevations falling wholly or partially within the territorial sea of a high-tide feature, which may
serve as part of the baseline for the territorial sea of that high-tide feature, and low-tide
elevations located beyond the territorial sea, which “have no capacity to generate claims tomaritime jurisdiction.”269
292. The Philippines submits that each of the five maritime features mentioned in its Submissions
No. 4 and 6 is a low-tide elevation:

Second Thomas Shoal, Mischief Reef, Subi Reef,“McKennan Reef including Hughes Reef” (which the Philippines treats as single feature), and
the Gaven Reefs. The Philippines distinguishes between them, however, and considers that
Second Thomas Shoal, Mischief Reef, and Subi Reef lie beyond 12 nautical miles from any
high-tide feature. In contrast, the Philippines considers that the Gaven Reefs lie within the
12-nautical-mile territorial sea of Namyit Island and that McKennan Reef lies within the
12-nautical-mile territorial sea of Sin Cowe Island, such that both low-tide elevations can beused to extend the baseline of the territorial sea of the high-tide features.270
293. The Philippines supports its conclusions with two types of satellite imagery.

First, thePhilippines has provided the Tribunal with what it describes as “multi-band Landsat satellite

photographs of each of the five low-tide features.”271 According to the Philippines, this imagery
was prepared as follows:
Two sets of images were produced from different parts of the electromagnetic spectrum
resulting in varying wavelengths. The band 1 images correspond to a shorter wavelength of
between 0.45 and 0.52 micrometres, and these can penetrate water. The band 4 images
correspond to a longer wavelength of between 0.76 and 0.90 micrometres, which are almost
entirely absorbed by water. A band 4 image can therefore only show features that are
above water.272

The Philippines submits that Landsat imagery of each of the five features confirms that none isabove water at high tide.273
294. Second, the Philippines has provided the Tribunal with satellite imagery analysis prepared by
the EOMAP company that depicts the five features bathymetrically at what EOMAP calculates
to be Lowest Astronomic Tide, Highest Astronomic Tide, and Mean High Water. 274 The
Philippines submits that EOMAP’s analysis likewise confirms that all five features are below
water at high tide.275
295. In addition to satellite analysis, the Philippines relies on what it considers to be the consistentdepiction of all five features as low-tide elevations in all published charts and on thecorresponding descriptions of the features as submerged at high tide in sailing directions andpilots. The Philippines summarises its conclusions on the available evidence as follows:
We have collected all the available charts and other evidence we can find. The satellite
imagery, including the EOMAP analysis of each of the features, consistently, completely
and without the slightest ambiguity demonstrates that all five features are covered by waterat high tide. This is simply not an issue and cannot reasonably be disputed.
The charts produced by all the relevant charting agencies—including the Philippines,
China, Malaysia, Vietnam, the United Kingdom and the United States—agree that all fivefeatures are low-tide elevations. All of the evidence, including the satellite imagery andthe Sailing Directions set out in the Atlas, is remarkably—and, we say, gloriously—
consistent in its depiction of the features as low-tide elevations.276

296. During the hearing, the Philippines was questioned by the Tribunal regarding the depiction of
the Gaven Reefs in U.S. Defense Mapping Agency Chart No. 93043 (Tizard Bank South China

The South China Sea Arbitration
Award of 12 July 2016Sea)277 and the description of the feature in the U.S. Sailing Directions (Enroute), South China
Sea and the Gulf of Thailand.278 The Philippines responded as follows:
Taking the U.S. Sailing Directions first, the relevant passage is on your screens. It is truethat there is a reference to a white sand dune, and the third sentence says that it is 2 metreshigh. But the Sailing Directions does not say that the sand dune is “above water at hightide”; in fact, it says the opposite. The first sentence states without ambiguity that both
reefs are covered by water at high tide. The white sand dune mentioned in the third
sentence is properly read as a reference to its situation at less than high water.
Both the Philippines and Chinese Sailing Directions support this interpretation. The
Philippine Coast Pilot explains that Gaven Reefs “cover at [high water]”, and the Chinese
Sailing Directions states explicitly that, “these rocks are all submerged by seawater”. And
these are the words, we say, that dominate.
I turn to US chart no. 93043, referred to in the Tribunal’s question. You can see it on yourscreens. You can now see the datum for the chart; it is highlighted. This is based on a
Japanese survey undertaken in 1936 and 1937. As to the heights—this is significant—theseare expressed in “metres above mean sea level”. Mean sea level is not the same as hightide; it is a lower level. It cannot therefore be concluded on the basis of this chart—an old
chart of about 80 years of age—that any part of Gaven Reef is above water at high tide. 279

The Philippines also emphasised that the EOMAP imagery of the Gaven Reefs gives no
indication of a high-tide feature.280
297. During the hearing, the Philippines’ expert was also questioned by the Tribunal as to whether or
not Subi Reef lies within 12 nautical miles of a high-tide feature on the reefs to the west of
Thitu Island. In response, the Philippines submitted additional analysis from EOMAP and thefollowing conclusion:
Both the U.S. and UK Sailing Directions indicate that a sand cay lies on one of the reefs
approximately 3.5 nautical miles from Thitu. However, U.S. chart NGA 93044 (2nd ed.
5/84) has removed the indication of a cay that had been present on the previous U.S. chartof the area, NGA 93061B (4th ed. revised through 9/70). Currently, only British Chart
3483 shows the presence of a tiny cay on one of these reefs. Charts published by thePhilippines, China, Vietnam, Japan and Russia give no indication of any feature above
water at high tide among these reefs.
When the satellite imagery used in the EOMap analysis was taken, the tidal level was
determined (by EOMap) to be 71 cm below Mean High Water. Even at that relatively low
tidal level, the two westernmost reefs were completely submerged.
On the three easternmost reefs, there are indications of tiny sand spits that had uncovered atthat tidal level. While it is likely that these sandy areas cover fully at tidal levels
approaching Mean High Water, the EOMap analysis automatically depicts them as small

4.

China’s Position

298. China has not, as far as the Tribunal is aware, specifically set out its position with respect to allof the maritime features at issue in these proceedings. Indeed, the Tribunal recalls that in its
public Position Paper of 7 December 2014, China stated that:
The Philippines asserts that some of the maritime features, about which it has submitted
claims for arbitration, are low-tide elevations, thus being incapable of appropriation as
territory. As to whether those features are indeed low-tide elevations, this Position Paper
will not comment.282

299. The Tribunal notes, however, that the record of public statements and diplomatic
correspondence before it includes the Chinese statement that “Huangyan Dao [ScarboroughShoal] is not a sand bank but rather an island.”283
300. The Tribunal also notes China’s statement that “China has indisputable sovereignty overNansha Islands and their adjacent waters, Meiji Jiao [Mischief Reef] and Yongshu Jiao [Fiery
Cross Reef] included.”284 This statement is not entirely without ambiguity, but the Tribunal
understands it to mean that China considers Mischief Reef and Fiery Cross Reef to be high-tidefeatures, entitled to at least a territorial sea.
301. China has also commented on the entitlements of the maritime features of the Spratly Islands
collectively, stating that “China’s Nansha Islands is fully entitled to Territorial Sea, Exclusive
Economic Zone (EEZ) and Continental Shelf.”285
302. The Tribunal recalls the statement in its Award on Jurisdiction that “a dispute is not negated by
the absence of granular exchanges with respect to each and every individual feature.”286 Where
China has not publicly stated its specific view regarding the status of a particular feature, the281

Tribunal will assess the status of the feature on the basis of the best evidence available to it,
paying particular attention to the depiction of features on nautical charts or the descriptions insailing directions issued by China.
5.

The Tribunal’s Considerations(a)

The Interpretation of Article 13 and the Tribunal’s Approach to
Submissions No. 4 and 6

303. The definition and properties of low-tide elevations are set out in Article 13 of the Convention,
which provides as follows:
Article 13
Low-tide elevations
1.

A low-tide elevation is a naturally formed area of land which is surrounded by andabove water at low tide but submerged at high tide. Where a low-tide elevation issituated wholly or partly at a distance not exceeding the breadth of the territorial sea
from the mainland or an island, the low-water line on that elevation may be used as
the baseline for measuring the breadth of the territorial sea.

2.

Where a low-tide elevation is wholly situated at a distance exceeding the breadth of
the territorial sea from the mainland or an island, it has no territorial sea of its own.

304. This definition operates in parallel with that of an island in Article 121(1) of the Convention,
which provides that “[a]n island is a naturally formed area of land, surrounded by water, which
is above water at high tide.” The latter Article will be discussed in detail subsequently inconnection with the Philippines’ Submissions No. 3, 5, and 7 (see paragraphs 473 to 553
below).
i.

Naturally Formed Areas and the Human Modification of Coral Reefs

305. With respect to low-tide elevations, several points necessarily follow from this pair ofdefinitions. First, the inclusion of the term “naturally formed” in the definition of both a low-tide
elevation and an island indicates that the status of a feature is to be evaluated on the basis of its
natural condition. As a matter of law, human modification cannot change the seabed into a
low-tide elevation or a low-tide elevation into an island. A low-tide elevation will remain alow-tide elevation under the Convention, regardless of the scale of the island or installation built
atop it.
306. This point raises particular considerations in the present case. Many of the features in the South
China Sea have been subjected to substantial human modification as large islands withinstallations and airstrips have been constructed on top of the coral reefs. In some cases, itwould likely no longer be possible to directly observe the original status of the feature, as the131The South China Sea Arbitration
Award of 12 July 2016

contours of the reef platform have been entirely buried by millions of tons of landfill andconcrete. In such circumstances, the Tribunal considers that the Convention requires that thestatus of a feature be ascertained on the basis of its earlier, natural condition, prior to the onsetof significant human modification. The Tribunal will therefore reach its decision on the basis of
the best available evidence of the previous status of what are now heavily modified coral reefs.
ii.

The Status and Entitlements of Low-Tide Elevations

307. The Philippines’ Submissions request the Tribunal to declare that those features which qualify
as low-tide elevations under Article 13 are not entitled to maritime zones and are not capable ofappropriation or occupation. These Submissions thus raise the question of the status andentitlements of low-tide elevations.
308. Article 13(2) states that, except where a low-tide elevation falls within the breadth of aterritorial sea generated from a high-tide feature or mainland, it generates no territorial sea of its
own. Article 13(2) does not expressly state that a low-tide elevation is not entitled to an
exclusive economic zone or continental shelf. Nevertheless the Tribunal considers that thisrestriction is necessarily implied in the Convention. It follows automatically from the operationof Articles 57 and 76, which measure the breadth of the exclusive economic zone andcontinental shelf from the baseline for the territorial sea. Ipso facto, if a low-tide elevation is
not entitled to a territorial sea, it is not entitled to an exclusive economic zone or continental
shelf. The same restriction follows implicitly from Article 121(3), which provides that evencertain high-tide features are deemed to be rocks that are ineligible to generate an exclusive
economic zone or continental shelf.
309. With respect to the status of low-tide elevations, the Tribunal considers that notwithstanding theuse of the term “land” in the physical description of a low-tide elevation, such low-tide
elevations do not form part of the land territory of a State in the legal sense. Rather they form
part of the submerged landmass of the State and fall within the legal regimes for the territorial
sea or continental shelf, as the case may be. Accordingly, and as distinct from land territory, theTribunal subscribes to the view that “low-tide elevations cannot be appropriated, although ‘acoastal State has sovereignty over low-tide elevations which are situated within its territorialsea, since it has sovereignty over the territorial sea itself’.”287

iii.

Vertical Datum and the Meaning of “High Tide” in Articles 13 and 121

310. A further consideration is posed by the use of the term “high tide” in the definition of both alow-tide elevation and an island. “High tide” is not a technical term and is potentially subject toa number of different technical interpretations, corresponding with different measurements andwater levels. Common datums for measuring high water include Mean High Water (the averageheight of all high waters at a place over a 19-year period), Mean Higher High Water (theaverage height of higher high water at a place over a 19-year period), and Mean High Water
Springs (the average height of the high waters of spring tides). 288

The International

Hydrographic Organization (the “IHO”) recommends that a high-water datum be used as thereference datum for heights depicted on nautical charts, but makes no recommendation as
between the possibilities.289 The IHO specifically recommends that Highest Astronomic Tide(the highest tidal level which can be predicted to occur under average meteorological conditions
and under any combination of astronomical conditions) be used as the datum for verticalclearances (i.e., bridges), but only for this purpose.290
311. The Tribunal sees nothing in the Convention, and no rule of customary international law, thatwould mandate that the status of low-tide elevations and high-tide features/islands be
determined against any particular high-water datum. Accordingly, the Tribunal considers that
States are free under the Convention to claim a high-tide feature or island on the basis of any
high-water datum that reasonably corresponds to the ordinary meaning of the term “high tide”
in Articles 13 and 121. Ordinarily, this would also be the height datum for nautical charts
published by that State, above which rocks would be depicted as not covering at high tide.
312. In the present case, the situation is complicated by the fact that the features in question areclaimed by multiple States and may or may not lie within one or another State’s exclusive
economic zone and continental shelf. The Tribunal questioned the Philippines on the issue ofvertical datum at several points during the proceedings, and the Philippines responded as follows:
There is no requirement under the Convention to have regard to any particular charts todetermine the status of a feature; and in any event, in this case all the charts point in thesame direction. And we have made clear that the Philippines has no objection to this Tribunal

placing reliance upon the Chinese charts which we have referred to in our written
pleadings.291

The Philippines’ elaboration of this answer, however, appeared to be focused on the low-water
datum on various charts,292 against which soundings and baselines would be measured, whereas
the determination of the status of a feature would necessarily be measured against a high-water
datum.
313. Height datum on modern charts produced by the Philippines is Mean High Water. 293 In
contrast, the height datum on modern Chinese charts is China’s 1985 National Vertical Datum,
which corresponds to Mean Sea Level in the Yellow Sea as observed at Qingdao.294 Mean sea
level is not a high-water datum, and this therefore offers no assistance in determining theappropriate datum for “high tide” for the purposes of Articles 13 and 121. However, the legend
to the symbology for standard Chinese cartography indicates that Chinese charts will depict arock or islet as one which does not cover if it exceeds the level of Mean High Water Springs. 295
Several of the Chinese charts in the record before the Tribunal also include tidal information
and reference “high tide” as Mean Higher High Water.296 The Tribunal considers that either
Mean Higher High Water or Mean High Water Springs would be an appropriate approximationof “high tide” if determined on the basis of Chinese nautical charts. The Tribunal is also awareof certain statements in the record before it to the effect that the tidal regime in the South China
Sea is complex and unpredictable. The Tribunal will address this issue in the following Section(see paragraphs 314 to 319 below). Ultimately, however, the tidal range in the South China Sea
is comparatively small and the selection of a vertical datum will, in most instances, make no
difference regarding the status of a feature. The Tribunal need consider this issue further only if

it appears that a feature is near enough to high water that its status would differ as a result of thedatum used.
iv.

Tidal Patterns and Ranges in the Spratly Islands

314. Tides in the South China Sea raise a further consideration: namely, whether the Tribunal has
sufficient information to accurately understand tidal patterns in the South China Sea and theireffect on the various features at issue in the proceedings. The Tribunal notes that the Royal
Navy carried out tidal measurements at Spratly Island in 1864297 and at North Danger Reef in1926,298 in both instances with a series of direct observations that appear long enough to coverat least a fortnight within the lunar cycle. Tidal ranges299 from these observations are reported
in the sailing directions300 and appear on the 1864 fair chart of Spratly Island301 and on the 1926
fair chart of North Danger Reef.302 They indicate a spring tide range of 5¼ feet (1.6 metres) at
Spratly Island and a range between Higher High Water and Lower Low Water of 3 feet
(0.91 metres).303 Royal Navy Fleet Charts issued through 1966304 also indicate the tidal range
for North Danger Reef with a range between Higher High Water and Lower Low Water of
2.7 feet (0.82 metres) and range for spring tides of 4.6 feet (1.40 metres).
315. The Chinese charts in the record also record tidal ranges, taken at the Gaven Reefs, Hughes
Reef, Fiery Cross Reef, Cuarteron Reef, and Subi Reef. These locations all correspond withcurrent Chinese installations, suggesting that the results are based upon in-person observations
over a period of time and may be considered reliable. This Chinese tidal data indicate that mean
tidal ranges are quite consistent across the different features in the South China Sea, althoughsome differences in tidal intervals are apparent. Chinese tidal data also provide greater detail on

In tide terminology, the amplitude is the semi-range of the harmonic constituent. See International
Hydrographic Office, Hydrographic Dictionary, Part I, Vol. I, at p. 11 (5 th ed., 1994). The tidal range isthe difference in height between high tide and low tide. The tidal amplitude is the difference in height
between high tide (or low tide) and the level of mean tide. In other words, the amplitude is half the tidal
range.

the effect of changes in lunar declination and indicates a range between Higher High Water andLower Low Water of 0.5 metres (1.64 feet) with minimal lunar declination, increasing to 1.2
metres (3.94 feet) at maximum declination. Tidal data on pre-war Japanese charts of North
Danger Reef and Tizard Bank are also available,305 indicating a maximum tidal range between
Higher High Water and Lower Low Water of 1.6 metres at North Danger Reef and 1.8 metres at
Itu Aba.
316. The Tribunal notes that the British and Chinese data on tidal ranges are remarkably consistentand that the British range between Higher High Water and Lower Low Water of 0.82 metresnearly matches the average of 0.85 metres of the higher and lower Chinese calculations. Taken
as a whole, the Tribunal is comfortable with the conclusion that the average range between
Higher High Water and Lower Low Water for tides in the Spratlys is on the order of 0.85
metres, increasing to 1.2 metres during certain periods of the year. The slightly higher ranges
indicated from Japanese surveys may be an outlier and can be viewed as an outer limit on the
expected tidal range. These are not particularly large tidal ranges, and the differences between
different possible high-water datums would be correspondingly small.
317. The Tribunal takes note of the statement in the Schofield Report that “defining tidal levels is
likely to be technically challenging in the context of the complex tidal regime of the South
China Sea which is variable spatially and temporally and which has not been subject to detailedhydrographic surveys in recent times.” 306 In this respect, the Tribunal considers that any
complexity with respect to tides concerns the South China Sea as a whole, in particular coastal
areas, but does not necessarily pose an issue for the Spratly Islands. The Tribunal notes thattidal regimes tend to be much more complex and variable in shallow-water areas near to theshore of large land masses, or in bays or straits, than in open, deep-water areas or around305

Prescott & R. van der Poll, An Appraisal of the Geographical Characteristics andStatus of Certain Insular Features in the South China Sea, p. 7 (March 2015) (Annex 513) (hereinafter“Schofield Report”). The authority cited by the Schofield Report for this proposition further states, on
the basis of the coastal tidal data of the Philippines and Malaysia, that:
The tides in the SCS are among the most complex in the world. In addition to a varying
bathymetry, bays, gulfs and straits, the ocean circulation system in the SCS crosses theequator. These extraordinary features result, in some locations, in a changing semi-diurnaland diurnal pattern of the tidal cycle in the course of each year or even in the course of one
month (a moon cycle) and is not geographically homogeneous. The west side of the basin
is generally dominated by a semi-diurnal tidal cycle, whereas the east side is more mixed.
The tidal range also varies from close to nil to a predicted 2m during spring tides in thenorthern part of the Spratlys.

isolated reefs. Variability in tidal patterns along the coasts of the South China Sea does notindicate similar variability in the central area of the Spratly Islands. The Tribunal, assisted by
its expert hydrographer, also recalls that it has before it a substantial amount of information on
historical observations of tidal ranges in the Spratly Islands that is remarkably consistent andincludes recent tidal observations from the modern Chinese charts, which are consistent with thetidal ranges reported historically.
318. The Tribunal thus considers that it has sufficient evidence to closely estimate the average tidal
range at features in the Spratly Islands. The Tribunal also notes that the Royal Navy of theUnited Kingdom, Japanese Navy, and Chinese Navy all appear to have had a thoroughunderstanding of tides in the Spratly Islands, such that direct observations on features from such
sources can be assumed to have been based on an accurate understanding of the tidal conditions
at the time the observations were made. This would be particularly true in the case of direct
observations made in the course of a survey, where the officers in question would have beenpresent in the area of a feature for days or weeks at a time. Recalling the caveat to its decision
with respect to its jurisdiction over Submissions No. 4 and 6, the Tribunal does not consider that“practical considerations for the selection of the vertical datum and tidal model against which
the status of the features is to be assessed”307 pose a hurdle to the assessment of the status offeatures identified in the Philippines’ Submissions.
319. At the same time, although the Tribunal is comfortable that it has a sufficient understanding of
the average tidal range in the Spratly Islands and that this would suffice for interpreting charts
or survey data, the Tribunal is not convinced that it is feasible accurately to model the pattern
and timing of tides in the Spratly Islands. The Tribunal notes that Chinese tidal data indicate
greater variation in the tidal intervals across different features than it does with respect toranges. The Tribunal thus does not believe that it is feasible to predict with sufficient certainty
the exact tidal state at a particular feature at any precise point in time. This conclusion will have
implications for the Tribunal’s views (discussed below) on the utility of satellite imagery.
(b)

Evidence on the Status of Features as Above/Below Water at High Tide

320. Before turning to the examination of particular features, the Tribunal considers it appropriate toaddress certain issues concerning the available evidence on the status of features.
321. As a general matter, the most accurate determination of whether a particular feature is or is notabove water at high tide would be based on a combination of methods, including potentially
307

Award on Jurisdiction, paras. 401, 403.

137

The South China Sea Arbitration
Award of 12 July 2016

direct, in-person observation covering an extended period of time across a range of weather andtidal conditions. Such direct observation, however, will often be impractical for remote features
or, as in the present case, impossible where human modifications have obscured the original
status of a feature or where political considerations restrict in-person observation. The Tribunal
considers it important that the absence of full information not be permitted to bar theconclusions that reasonably can be drawn on the basis of other evidence. At the same time, thelimitations inherent in other forms of evidence must be acknowledged.
i.

Satellite Imagery

322. In attempting to overcome the absence of recent, direct observation of the features in question,
the Philippines has placed heavy reliance on remote sensing through satellite imagery. The
Tribunal agrees with the general point that satellite imagery may be a very useful tool, butcannot accept the degree of accuracy or certainty that the Philippines would give to such
imagery. The Philippines has, for instance, relied upon a spectral analysis of imagery derived
from the Landsat 4, 5, 7, and 8 satellites.308 According to the Philippines, such a comparison ofimages will establish whether any portion of a reef is above water at high tide, as the ability ofdifferent wavelengths of light to penetrate water differs (see paragraph 293 above).309 Landsat 4
and 5, however, are satellites with a 30-metre ground resolution, meaning that each pixel of theimage is equal to a square on the ground of 30 metres on each side.310 Landsat 7 and 8 include apanchromatic (black and white) band with a ground resolution of 15 metres, but otherwise havethe same 30-metre ground resolution for the spectral bands as the earlier Landsat 4 and 5. In thecourse of the hearing, the Tribunal asked the Philippines’ expert to clarify whether the imagery
analysed included the use of the panchromatic band (sensitive to all wavelengths of visible lightand thus black and white in appearance), which would represent a commonly used process
known as pansharpening, in which a higher resolution panchromatic image is used to increase
the resolution of a colour image. The Philippines’ expert indicated that this had not been done.
Whether or not this is the case, however, the maximum resolution that could possibly be derived
from the satellite imagery used by the Philippines for this purpose is 15 metres. Small rocks orcoral boulders on a reef platform may be a metre or less across and still reach above water athigh tide. The resolution of the satellite imagery being used here is insufficient to establish thepresence or absence of such features.

323. The Philippines’ expert report also makes use of higher resolution imagery from the Worldview
family of satellites, with a ground resolution of 0.46 metres (panchromatic).311 However, thisimagery was generally used for high-tide features and not for spectral analysis to detect thecoverage of low-tide elevations at high water. Such imagery may be helpful, but as with any
satellite imagery, will also suffer from the difficulty that the time of image capture will
generally not align with either high or low tide. The precise tidal conditions prevailing at thetime the image was taken can only be estimated, unless confirmed by observations on the
ground that coincide with the time the images were taken.
324. The analysis provided by the Philippines from EOMAP also suffers from inherent verticalaccuracy limitations due to the necessary reliance on predicted tidal information, as well as due
to assumptions that are made in the spectral analysis.

As an initial matter, the EOMAP

materials provide no explanation of the vertical accuracy of their image processing. As ageneral matter, the Tribunal understands that Landsat satellite-derived bathymetry of this type
involves a base error of at least ± one-half metre and a further error of ± 25 percent of the water
depth. For WorldView satellites the further error is understood to be less, at ± 10 percent of thewater depth. A further difficulty with the EOMAP materials is posed by tidal conditions. The
tidal datum used by EOMAP for determining high-tide features is Highest Astronomical Tide,
which is normally used to determine clearances for vessels from bridges and other overhead
structures and not for the categorisation of features. Additionally, EOMAP has not (and could
not have) presented imagery of the features that was actually captured during the tidal
conditions represented. Rather, EOMAP has used imagery captured at a single point in timeand extrapolated the results for other tidal conditions on the basis of a model of the tidal
conditions at the time the image was captured. The accuracy of EOMAP’s presentation of any
particular tidal state is thus entirely dependent on EOMAP’s model of the tidal state on thefeature at the precise moment the image was captured. How this fundamental calculation was
obtained is nowhere explained to the Tribunal. The Tribunal accepts that it is reasonably
possible to predict the general maximum range of tides in an area on the basis of pastobservations, as well as the normal interval between high and low tides. The tidal range on theparticular day that satellite images were taken, however, would necessarily be affected byatmospheric conditions, which would add a further degree of error into the calculation.
325. A final difficulty with the use of EOMAP imagery to determine the status of features isdemonstrated by the EOMAP analysis of the Thitu Reefs, provided by the Philippines following

the Hearing on the Merits. According to the information provided, the imagery was captured ata time when the tide on the Thitu Reefs was “71 cm below Mean High Water.”312 Several areasof the Thitu Reefs were exposed at this time, but EOMAP’s imagery does not capture abovewater topographic information, and these areas appear simply as white spaces. It is impossible
to know whether these areas were barely exposed and likely to cover, or well above water at thetime the image was taken. Instead, the areas most relevant to the classification of the feature
were rejected as “data flags” from a process that is, ultimately, directed at bathymetricconditions, rather than surface features.
326. As the Philippines correctly notes, satellite imagery is most beneficial when used in conjunction
with other evidence,313 and the Tribunal considers that satellite imagery may be able to disprovethe existence of large sand cays or features where the area in question clearly covers with water
across a series of images. Additionally, the more far-reaching conclusions advanced by thePhilippines regarding the (non-)existence of small sand cays or rocks could perhaps beestablished with very high-resolution stereoscopic imagery, taken at or near high tide, with
in-person observations of tidal conditions taken at a nearby location. Absent such information,
however, the Tribunal does not believe that the majority of the conclusions it has been asked toreach concerning the status of features as above or below water at high tide can be drawn on thebasis of satellite evidence alone.
ii.

Nautical Surveying and Sailing Directions

327. Given the impossibility of direct, contemporary observation and the limitations on what can beachieved with remote sensing, the Tribunal considers that more convincing evidence concerning
the status of features in the South China Sea is to be found in nautical charts, records of surveys,
and sailing directions. Each of these sources, the Tribunal notes, represents a record of direct
observation of the features at a past point in time. Rocks and large coral boulders cemented tothe platform of a reef have a high degree of permanence and can reasonably be expected toremain largely unchanged, even over centuries. Older direct observations are thus not per seless valuable, provided they are clear in content and obtained from a reliable source. Moreephemeral features such as sand cays pose a greater challenge, but can also be consistent overtime and will often reform in the same location if dispersed by a storm.
328. The Philippines has introduced a substantial quantity of chart evidence, as well as extracts froma large number of different pilots and sailing directions and emphasises that its conclusions are

140

Award of 12 July 2016

drawn not from any single source, but from the confirmation of consistent evidence acrossmultiple sources. 314 The Tribunal will address this evidence specifically in the context ofparticular features, but considers several preliminary observations to be warranted.
329. As an initial matter, the Tribunal considers it more important to focus on the timing of surveys,
rather than the publication of charts. There have been many nautical charts of the South China
Sea published, but its features have only been surveyed on a few occasions. The details of thesesurveys are clearly laid out in several publications in the record before the Tribunal.315 In brief,
the first survey work to focus sustained attention on the features in the South China Sea wasundertaken by the British Royal Navy between 1862 and 1868. Subsequently, both the Royal
Navy and the Imperial Japanese Navy were intensively engaged in surveying the Spratly Islandsin the 1920s and 1930s, although much of this information only became public well after theend of the Second World War. The French and American navies also engaged in survey workin the 1930s, although to a lesser degree. More recently, the littoral States surrounding theSouth China Sea have undertaken their own work, generally in the areas more closely adjacentto their coasts.
330. The majority of the nautical charts of the South China Sea issued by different States, however,are to a greater or lesser extent copies of one another. Often, information is incorporated oroutright copied from other, existing charts without express attribution. Where a chain ofsources can be established, even very recent charts will often trace the majority of their data to
British or Japanese surveys from the 1860s or 1930s. A more recently issued chart may, in fact,include little or no new information regarding a particular feature. Multiple charts depicting afeature in the same way do not, therefore, necessarily provide independent confirmation that thisdepiction accords with reality.

Nor should differences between charts at different scales

necessarily be considered significant. Only a few of the nautical charts in the record arelarge-scale, depicting some of the features addressed by the Philippines at a scale of 1:150,000
or less. This paucity of large-scale charting reflects the remoteness of many of the reefs, thelimited amount of detailed survey work in the area, and the lack of a need for more detailedplans, except for military purposes. The Tribunal has identified some relevant evidence innautical charts up to 1:250,000 scale. Beyond this, however, the Tribunal does not consider that
small-scale charts at 1:500,000 or 1:1,000,000 offer meaningful evidence of the absence of tiny

The South China Sea Arbitration
Award of 12 July 2016high-tide features rising above a covering reef. This is particularly the case on recent charts
where the trend appears to be to depict less information concerning features on a reef platform
as satellite navigation decreases the need for visual orientation.
331. In light of the limitations in the chart evidence before it, the Tribunal questioned the Philippines
as to whether it had sought the original fair charts of surveys conducted on the features in the
Spratly Islands. The Philippines indicated that it considered the consistent depiction of featuresin published charts to be sufficient. 316 The Tribunal disagrees and considers that, in any
sensitive determination, it will very often be beneficial to have recourse to original survey data,prepared by individuals with direct experience and knowledge of the area in question. The
Tribunal takes note of the comments of the International Court of Justice on the probative valueof historical surveys in Nicaragua v. Colombia,317 but believes they must be understood in thecontext of that case. The Convention gives important weight to published nautical charts, andArticle 5 provides for States to use the low-water line on large-scale charts as the baseline forthe territorial sea. This provision, however, envisages a situation in which a State is presenting
information concerning its own coastlines in areas that can be expected to be well surveyed andwell charted by that State. Considerations of an altogether different order arise where, as here, adetermination involves the status of remote features, subject to the demands of competing
States, that have been carefully surveyed only infrequently. The revision of charts may correct
errors or introduce new information, but publication also necessarily involves a process of
selection and intermediation that may exclude information of particular relevance. Accordingly,
the Tribunal has independently sought materials derived from British and Japanese surveys andhas provided them to the Parties for comment. Many of the Tribunal’s conclusions in thisSection are drawn from this material.
332. Finally, the Tribunal notes that sailing directions may offer an alternative source of first-handobservations of the features in question. The record indicates that the descriptions of reefs inthe first edition of the British China Sea Directory were drafted aboard HMS Rifleman in thecourse of conducting the survey.318 Later British surveys in the 1920s and 1930s also sent backamended or supplemental descriptions for direct incorporation into the sailing directions.319 The

edition of a pilot following survey operations can thus be read more as a first-hand account of
the area and features, rather than simply a technical document. In contrast with the British
practice, however, the sailing directions of other States appear to be principally derived from the
British text, with the exception of the U.S. sailing directions, which appear to have been basedon Japanese information, and the Chinese sailing directions, which appear to include
independent information. As with published nautical charts, satellite navigation has also caused
the more-recent editions of the pilots to become less descriptive of the features on reefs andcorrespondingly less useful to the particular determination presented to the Tribunal.

The Status of Particular Features in the South China Sea
i.

Scarborough Shoal

333. Scarborough Shoal was surveyed in detail by HMS Swallow in 1866 and by HMS Herald in
1932. The fair plans of the two surveys indicate between five and seven rocks that are clearlymarked as being between one and three feet above high water. The same rocks are depicted insome of the published nautical charts before the Tribunal 320 and are confirmed in all of therelevant sailing directions, 321 including the China Sailing Directions: South China Sea
published by the Navigation Guarantee Department of the Chinese Navy Headquarters, which
describes the reef as follows:
Huangyan Island (Democracy Reef) Located 340 nautical miles southerly of Yongxing
Island, it is the only atoll among these islands to be exposed above sea level. Its shaperesembles an isosceles triangle, the west side and south side are each 15 km long, and thesurface area is approximately 150 sq. km. The reef basin has a crest width of 1 km - 2 km,
and the northern part is 3.3 km at its widest part. In general, the water depth is 0.5 meters 3.5 meters. Hundreds of large reef segments are distributed along the top surface and are
0.3 meters – 3.5 meters above sea level. The North Rock on the northwest end and theSouth Rock on the southeast end have a surface area of approximately 10 sq. meters. They
are respectively 1.5 meters and 1.8 meters above sea level. The water depth within the
lagoon is 10 meters – 20 meters. The east side of South Rock has a 400-meter wide
waterway, and boats can come in from the open seas to anchor.322

ii.

Cuarteron Reef

335. Cuarteron Reef and the other London Reefs were visited by HMS Rifleman in 1864 and 1865,
but no comprehensive survey of Cuarteron Reef appears to have been undertaken, likely due tothe difficulty in finding any anchorage on the steep slopes of the feature.323 Cuarteron Reef wasvisited again in 1938 by HMS Herald in the course of her secret work in the South China Sea,and those observations were incorporated into the 1951 edition of the China Sea Pilot whichclearly reports a number of rocks above water at high tide:
Cuarteron reef, about 10 miles eastward of East reef, dries and is encumbered by rocks,
especially on its norther side, where some are from 4 to 5 feet (1 m2 to 1m5) high.
Anchorage was obtained by H.M. Surveying Ship Herald, in 1938, in a depth of about 15
fathoms (27m4), about one cable from the northern side; the southern side is steep-to. Thereis no lagoon.
The tidal streams set eastward and westward along the northern side of Cuarteron reef.
Although considerable depths were found, in 1865, close to all the London reefs, there was
generally some slope from the edges on which HMS Rifleman found safe anchorage for ashort period, but on Cuarteron reef no anchorage could be found. 324

reef with no lagoon in the center of the reef flat. It appears to be trending toward the east
and west. During high tide it is submerged. During spring tide and low tide, it is exposed,
and its middle part is low and flat.329

338. In the Tribunal’s view, the statement that “[d]uring high tide it is submerged” in the Chinese
sailing directions is better understood as stating that the reef platform is submerged at high tide,
rather than as disproving the existence of particular rocks above water at high tide. In contrast,
the references to rocks in the 1938 description of the reef are clear. In light of the purpose ofsailing directions in enabling visual navigation, this should be understood as a description ofrocks that remain visible at high tide. There is no more recent or more authoritative evidence
that would suggest the absence of high-tide rocks on Cuarteron Reef, and the Philippines does
not contest the status of Cuarteron Reef as a high-tide feature.
339. The Tribunal concludes that Cuarteron Reef in its natural condition was encumbered by rocks
that remain exposed at high tide and is, accordingly, a high-tide feature.
iii.

Fiery Cross Reef

340. Fiery Cross Reef was surveyed by HMS Rifleman in 1866, which produced a detailed fair chartof the feature, which is reproduced as Figure 4 on page 149 below. A prominent rock on thesouth-west end of the reef is clearly marked on the fair chart, although it is not described in the1868 edition of the China Sea Directory.330 Fiery Cross Reef was visited again by HMS Herald
in 1936, which forwarded the following amended description for the sailing directions:
The Fiery Cross or N.W. Investigator Reef is a coral reef having several dry patches, upon
most of which the sea breaks even in light winds, or with a slight swell. It is 14 miles long,north-east and south-west, and 4 miles wide. The largest dry patch is at its south-west end
and has a conspicuous rock, about 2 feet high (0m6), on the south-ease side about 4 cablesfrom the south-west extreme in Lat. 9° 33′ N., Long. 112° 53′ E. Anchorage is obtainable
in 13 fathoms (23m7) about 2 cables from the edge of the reef, with this rock bearing 062,
distant 7 cables.331

341. This description was incorporated into the 1951 edition of the China Sea Pilot, which clarifies
that “[a]t high water the whole reef is covered except a prominent rock . . . , about 2 feet(0m6),” 332 and is repeated in later editions of the China Sea Pilot, 333 in the U.S. Sailing

Directions: South China Sea in the following terms:
Yongshu Reef - Located at the southeast part of the Nansha Islands and the west end of theNanhua waterway’s south side, the reef is trending from northeast-to-southwest. Most of
the atoll is submerged underwater. During high tide, only the western end has 2 sq. metersof natural reef rock exposed. During low tide, there are 7 pieces of reef flat of varying sizes
that are exposed.336

342. There is no more recent or more authoritative evidence that would suggest the absence of ahigh-tide rock on Fiery Cross Reef, and the Philippines does not contest the status of Fiery
Cross Reef as a high-tide feature. The Tribunal also notes that the Philippines’ expert has noted
the possible existence of additional small sand cays on Fiery Cross Reef that remain above
water at high tide, 337 although the Tribunal recalls its observations on reliance on satellite
evidence (see paragraph 326 above).
343. The Tribunal concludes that Fiery Cross Reef, in its natural condition was encumbered by arock that remained exposed at high tide and is, accordingly, a high-tide feature.
iv.

Johnson Reef

344. Union Bank, including Johnson Reef, was not surveyed by HMS Rifleman in the 1860s, and thefirst Royal Navy survey of the area appears to have been undertaken by HMS Herald in 1931.
The fair chart of this survey is extremely accurate with respect to position and shape of featureson the Union Bank, as compared to modern imagery. This suggests both that the survey was
carefully done and that it benefited from the Royal Navy’s use of flying boats and aerial
photography in its 1931 survey operations. The fair chart is reproduced as Figure 5 on page 151
below, along with other surveys of Johnson Reef and clearly depicts a high-tide rock in thesouthern corner of the reef. The corresponding description of Union Bank in the Royal Navy’s
1944 sailing directions for the Spratly Islands, however, is vague and adds no detail concerning
Johnson Reef.

The South China Sea Arbitration
Award of 12 July 2016345. In addition to the British, the Imperial Japanese Navy was actively involved in surveying theSpratly Islands in the 1930s and published a plan of Union Bank as part of Imperial Japanese
Navy Chart No. 525 – Plans in the Southern Archipelago. That chart also clearly depicts asmall high-tide feature in the southern extremity of Johnson Reef.
346. The most detailed description of Johnson Reef, however, appears as part of the U.S. survey ofwhat was known as the “Pigeon Passage”, a safe route through the Spratlys from Half Moon
Shoal in the east to Fiery Cross Reef in the west that was surveyed by USS Pigeon andaccompanying vessels in 1935 and 1937.

The report of that survey includes plans anddescriptions of the principal reefs adjacent to the surveyed route, including a plan for what isincorrectly identified as “Sin Cowe Island”. However, from the shape of the reef formation, thecoordinates given for it, and its location in the sketch plan of Union Bank, entitled “Shoals Near
Sin Cowe Islands,” it is apparent that what USS Pigeon identified as Sin Cowe was, in fact,
Johnson Reef. The U.S. plan of that feature depicts numerous rocks and notes the coordinatesof a “largest rock”. The accompanying description of the feature was as follows:
Sin Cowe Island – Position of the largest rock, which is about 5 feet in diameter and four
feet high in S.E. corner is Latitude 9° 42′ 00″ N., Longitude 114° 16′ 30″ E. The reef wassighted 4.7 miles from a height of 70 feet. The island was underwater except for about six
rocks at S.E. corner. This is the southernmost of a cluster of about 20 shoals, (see sketches#3 and 4) that extend to the eastward for about 40 miles. These reefs were in two parallellines, the reefs in pair; one line is at an angle of about 050°T. from Sin Cowe and thesecond to the northwestward of the first at a distance of about 1.5 miles. The small reef tothe northwestward of Sin Cowe bears about 330° true. A coral dune was reported on thesoutheastern part of this small reef. It was also reported that these reefs were interconnected below the surface but that the channel between this reef and Sin Cowe Island
was probably navigable. The prevailing wind blew directly down the channel from 060°
true. Sin Cowe Island is fish-hooked in shape which is caused by a lagoon in its center
whose entrance is in the northeast corner of the island. The major axis of this island shoal
is about two miles in a north south direction and it varies in width from about one mile atthe north end to ½ mile at the south end. It is apparently of volcanic origin with a lining ofcoral around the lagoon.
The lagoon is long and narrow; appears deep at its entrance, shoaling gradually toward thehead. It might provide anchorage for not more than two submarines but this is doubtful.
Anchorage space is not recommended here due to the steep banks and large fissures in thecoral, although three mine sweepers have been at anchor here at the same time on thesouthwestern side of the shoal in water ranging from 17 to 30 fathoms. 338

347. A condensed description, correctly identified as Johnson Reef and describing the same rocks, is
set out in later editions of the U.S. sailing directions:
Johnson Reef (9°42'N., 114°17'E.), of brown volcanic rock with white coral around theinner rim, is located at the SW end of Union Atoll. Johnson Reef partly encloses a shallow
lagoon entered from the NE. The largest rock on the reef is about 1.2m high. Several other338

147

The South China Sea Arbitration
Award of 12 July 2016

rocks show above the water on the SE part of the reef; the remainder of the reef is reported
to be covered.339

348. Although a datum for this 1.2-metre height is not directly given, the definitions section of the
U.S. Sailing Directions indicates that height references refer to the plane of reference for thechart concerned. Other larger-scale U.S. charts in the area describe the plane of reference as
being Mean Sea Level. In light of the tidal ranges identified for the South China Sea (seeparagraph 316 above), a rock four feet or 1.2 metres above Mean Sea Level would be exposed
at high tide. The U.S. sailing directions also note that “several other rocks show above the water.”
349. No such rocks are reported in the Chinese Navy Headquarters China Sailing Directions: South
China Sea, which describe Johnson Reef as follows:
Chigua Reef - Located at the edge of the southwest end of the Jiuzhang reef group’s large
atoll, the reef flat is low-lying, it has no particularly obvious natural markers. During hightide, it is submerged. During low tide, it is exposed and has a shape resembling ahorseshoe.340

350. Chinese Chart No. 18400, however, depicts a height of “(0.9)” metres above Mean Sea Level in
the area of Johnson Reef corresponding with the high-tide elevation depicted in the British andJapanese materials. A 0.9-metre height above Mean Sea Level would be exposed even at MeanHigh Water Springs and would be exposed by nearly half a metre a Mean Higher High Water.
351. The Tribunal is thus presented with a British survey and Japanese plan that depict a high-tidefeature on Johnson Reef, a U.S. survey and sailing directions that describe a rock that would
likely be exposed at high water, Chinese sailing directions that are phrased in somewhat generalterms and make no mention of any rocks whatsoever, and a published Chinese chart indicating aheight above high water on Johnson Reef. Taken together, the weight of the evidence favours
the conclusion that Johnson Reef is a high-tide feature, which the Tribunal accordingly reaches.
v.

McKennan Reef

352. Like Johnson Reef and the other features making up Union Bank, McKennan Reef was notsurveyed before the 1930s. Also like Johnson Reef, the results of the British and Japanesesurveys from that period are consistent. On McKennan Reef, however, they do not show any
high-tide feature. Both surveys are reproduced as Figure 6 on page 153 below. Nor is any high339

tide feature evident in U.S. Hydrographic Office Chart No. 5667, published in 1951 on the basisof the earlier Japanese survey. 341 No sailing directions appear to include any description of
McKennan Reef and the British China Sea Pilot notes that Union Bank as a whole “has notbeen closely examined.”342
353. The Philippines argues that the “[c]harts produced by China, the Philippines, the UK and U.S.
and Japan all depict McKennan Reef as a low-tide elevation.”343 The Tribunal notes, however,that this statement is not wholly correct. China’s Chart No. 18400 depicts Union Bank at
1:250,000 scale, but does not support the position advocated by the Philippines. Although thechart does not include any symbol for a rock or island on the reef platform of McKennan Reef
itself, a height of “(2.3)” metres above Mean Sea Level is indicated directly adjacent to
McKennan Reef, with a notation that corresponds to that used on Chinese charts for featuresthat do not cover at high water. Such a height would be well above high water against any
datum. While the absence of any symbol on the reef platform itself might, at first glance, callthis height into question, the Tribunal notes that the same pattern of notation (an apparently barereef platform with an adjacent height) is used on the same chart to depict Namyit Island on
Tizard Bank, where a high-tide feature unequivocally does exist, and also Johnson Reef onUnion Bank. The source key to Chart No. 18400 indicates that certain areas of the Chart weresurveyed by China between 1989 and 2001 and that the data for Union Bank were derived from“1984, 1982 version of nautical chart.”
354. The Philippines also argues that no high-tide feature is apparent in the satellite bathymetrymaterials prepared by EOMAP, but the Tribunal is unwilling to give weight to this evidence forthe reasons discussed above (see paragraph 326). As between the earlier British and Japanesematerials depicting no high-tide feature on McKennan Reef and a more recent Chinese chart
depicting a height at McKennan Reef, the Tribunal concludes that the Chinese chart is to bepreferred as the more recent evidence and that the height indicated for McKennan Reef most
likely indicates a coral boulder pushed onto the reef platform and above high water by storm
action.

Hughes Reef

355. Like McKennan Reef and the other features making up Union Bank, Hughes Reef was notsurveyed before the 1930s.
356. In contrast to McKennan Reef, however, the British and Japanese surveys of Hughes Reef
undertaken in the 1930s suggest different conclusions. No high-tide feature is depicted on
Hughes Reef in the British fair chart of Union Bank, whereas Imperial Japanese Navy Chart
No. 525 depicts such a feature on the south-west corner of the reef.

Both surveys are

reproduced as Figure 7 on page 159 below. The same depiction as Imperial Japanese Navy
Chart No. 525 also appears in U.S. Hydrographic Office Chart No. 5667, which was based upon
the Japanese survey results. 344 No sailing directions appear to include any description ofHughes Reef.
357. The Philippines argues that the “[c]harts produced by China, the Philippines, the UK and US
and Japan all depict McKennan Reef as a low-tide elevation”345 and the Tribunal understands
that statement to apply equally to Hughes Reef, in light of the Philippines’ conflation of the two
features.

The Tribunal is reluctant, however, to draw significant conclusions from thecomparatively small scale (1:250,000 or smaller) depictions of the features on Union Bank inmore recent charts for the reasons outlined above (see paragraph 330). The Tribunal agrees that
the U.S. and Philippine charts at 1:250,000 do not depict any feature on the reef platform at
Hughes Reef, but notes that the same charts also do not depict any high-tide feature at
Sin Cowe, where a high-tide feature unequivocally exists. U.S. Defense Mapping Agency Chart
No. 93044 also indicates that its survey data for Union Bank are derived from Taiwan Authorityof China Chart No. 477A, which is, in turn, a reproduction of Imperial Japanese Navy Chart
No. 525, rather than the product of independent survey work.346 The Tribunal sees no reason toassume that the removal of any indication of a high-tide feature on Hughes Reef in Chart
No. 93044 reflects anything more than a reduction in detail corresponding with the decrease inscale from original 1:100,000 scale of Imperial Japanese Navy Chart No. 525 to the 1:250,000
scale of Chart No. 93044. At the same time, however, China’s Chart No. 18400 (the same chart
to note a height at McKennan Reef) includes no indication of a height or high-tide feature at
Hughes Reef.

The South China Sea Arbitration
Award of 12 July 2016358. In light of all of the evidence, the Tribunal concludes that Hughes Reef is a low-tide elevation.
Although the Japanese chart does appear to indicate a high-tide feature, no height is given forthis feature (in contrast to the depiction of a sand cay on Gaven Reef (North) on the Japanesechart of Tizard Bank) and the observation is not corroborated by any other evidence before the
Tribunal. Nor does it appear in the most recent Chinese chart.
vii.

Gaven Reefs

359. The Gaven Reefs lie on Tizard Bank, which constitutes one of the most-thoroughly surveyed
areas of the South China Sea. Tizard Bank was carefully surveyed by HMS Rifleman in 1867
and the large-scale fair chart of that survey does not depict a high-tide feature on the Gaven
Reefs. This and other depictions of Gaven Reef (North) are reproduced as Figure 8 on page 161
below. Nor is any high-tide feature mentioned in the original description of Gaven Reef (North)(unnamed at the time) in the 1868 version of the China Sea Directory, which reads as follows:
Two dangerous reefs, covered at high water, lie to the westward of Nam-yit; the first isoval-shaped, three-quarters of a mile long N.N.W. and S.S.E., the island bearing from it E.
7/8 N., distant 6 miles; the second is a mile long North and South, and nearly three-quartersof a mile broad at its northern end, narrowing to a point at the opposite end; this last is thewesternmost danger of the Tizard group, and its outer edge is in lat. 10° 13′ 20″ N., long.
114° 13′ 7″ E.347

360. The description of the Gaven Reefs appears essentially unchanged throughout the various
editions of the China Sea Directory and China Sea Pilot. A reference to a beacon on Gaven
Reef (North) appears in the 1951 edition of the China Sea Pilot,348 but has been removed by the
1964 edition.349
361. The Gaven Reefs were also extensively surveyed in the 1930s by the Imperial Japanese Navy,
which maintained a presence on Itu Aba Island in Tizard Bank prior to and during the Second
World War. The Gaven Reefs were depicted in a large-scale plan of the Tizard Bank, whichindicates a sand cay in the north-east corner of Gaven Reef (North) with a survey marker upon it
and the words “(height 1.9 metres)” in parentheses adjacent to the sand cay. 350

Sankaku Shō is a shoal about a mile in extent submerged at H.W. which forms the W.
extreme of Chizato Tai; there is a sand cay near its N.E. extremity. 351

362. The Japanese plan of Tizard Bank was reproduced after the war as U.S. Hydrographic Office
Chart No. 5659 in 1950 and reissued in 1974 as Defense Mapping Agency Chart No. 93043,
including a magenta overlay with additional details. This chart reproduces the Japanese plan
exactly (to the point that the parentheses surrounding the Japanese text on Gaven Reef (North)are printed on the U.S. chart, even though the text itself has been removed) and includes the
depiction of the sand cay and survey marker on Gaven Reef (North). The magenta overlay adds
the height of “1.9” adjacent to the sand cay, which appears to have been omitted from the 1950
printing. The magenta overlay appears to represent a revision of the plan on the basis ofadditional, Japanese-language information included in the original Japanese plan, but nottransposed to the first edition of the U.S. chart. The accompanying U.S. sailing directions
describe the Gaven Reefs in the following terms:
Gaven Reefs (10°12'N., 114°13'E.) is comprised of two reefs which cover at HW and lie
7 miles W and 8.5 miles WNW, respectively, of Namyit Island. They are the SW dangers
of Tizard Bank. The N of the two reefs is marked by a white sand dune about 2m high. 352

363. During the Hearing on the Merits, the Tribunal questioned the Philippines regarding Chart
No. 93043 and the U.S. sailing directions. The Philippines argued that no high-tide feature wasindicated insofar as (a) properly interpreted, the sailing directions describe a sand dune thatwould cover at high water; (b) the feature depicted on Gaven Reef (North) is a Japanese survey
marker; (c) the height of 1.9 metres is based on a datum of Mean Sea Level and does notindicate a height above high water; (d) a high-tide feature is not depicted on later U.S. charts, inparticular U.S. Defense Mapping Agency Chart No. 93044; and (e) the Chinese sailingdirections for the Gaven Reefs indicate that “[d]uring high tide, these reef rocks are allsubmerged by seawater.”353

The South China Sea Arbitration
Award of 12 July 2016(a)

It is certainly true that both the U.S. and Japanese sailing directions describe Gaven Reef
(North) as submerged at high water and also describe a sand cay on the reef. In the
Tribunal’s view, the proper interpretation of these descriptions is that the reef platform issubmerged at high water, while the sand cay remains exposed. Given that the purpose ofsailing directions is to facilitate visual navigation, references to particular rocks or cays
on a reef will generally describe features that remain visible points of reference at hightide when the reef itself is covered. In the absence of an indication that a rock or cay
covers at high water, the Tribunal would normally understand such a description to referto a high-water feature, even in the absence of an express indication of that fact.

(b)

Both the Japanese chart and the U.S. reproduction thereof clearly depict both a high-watersand cay and a Japanese survey marker on the north-east corner of Gaven Reef (North).
This is more clearly visible in the Japanese printing, but is also apparent upon close
examination of the U.S. chart.

(c)

The height of 1.9 metres on Gaven Reef (North) is referenced to a datum of Mean Sea
Level, as the chart itself indicates. In light of tidal ranges in the Spratly Islands indicatedby British and Chinese observations (see paragraph 316 above), a height of 1.9 metres
would be well above even Mean High Water Springs. Even using the somewhat higher
Japanese tidal information on Chart No. 93043 itself would place Highest High Water at
0.9 metres above Mean Sea Level and still a full metre below the height indicated for thesand cay on Gaven Reef (North).

(d)More recently published U.S. charts that include Tizard Bank do not reflect more recent
survey information. Chart No. 93044—which the Philippines considers to dispose of theexistence of a cay on Gaven Reef (North)—indicates that its survey data for Tizard Bankare derived from Taiwan Authority of China Chart No. 478. This chart is, in turn, a
reproduction of Imperial Japanese Navy Chart No. 523, rather than the product of
independent survey work.354 The “newer” U.S. chart thus reflects the same underlying
Japanese survey as the chart depicting a sand cay. The absence of detail on Gaven Reef
(North) is a result of the smaller 1:250,000 scale of the later chart, in comparison with the
1:75,000 scale of the earlier plan.

There appear to be some inaccuracies in the English translation of the Chinese sailingdirections for the Gaven Reefs provided by the Philippines, which properly translate as

Gaven Reef (Nanxun Reef) - Located at the southwest end of the Tizard Bank
(Zhenghe reef group), it is comprised of two coral reefs, one in the south and one in
the north. The relative positions of the two coral reefs appear to be trending from
northwest to southeast. The reef in the southeast direction is located approximately
six nautical miles west of Namyit Island (Hongxiu Island). During high tide, thesereef rocks are all submerged by seawater.355

Hongxiu Island is a reference to Namyit Island, which lies well beyond six nautical miles
from Gaven Reef (North). Read correctly, the Chinese sailing directions clearly state thatthe rocks at Gaven Reef (South) are submerged at high water.
365. The Tribunal therefore considers that it is faced not with uniform evidence concerning the status
of Gaven Reef (North), but with a 20th century Japanese survey depicting a sand cay on the reef
and a 19th century British survey indicating no such feature. As between the two, the Tribunal
considers that the Japanese evidence is to be preferred and sees no more recent evidence thatwould disprove the existence of a sand cay on Gaven Reef (North). Accordingly, the Tribunal
concludes that Gaven Reef (North) is a high-tide feature.
366. The Tribunal has seen no evidence in any of the sources discussed above that would suggest theexistence of a high-tide feature on Gaven Reef (South) and notes the description to the contraryin the Chinese sailing directions. The Tribunal concludes that Gaven Reef (South) is a low-tide
elevation.

Subi Reef

367. Subi Reef was surveyed along with the nearby Thitu Reefs in 1867 by HMS Rifleman. The
detailed fair chart of the feature is reproduced as Figure 9 on page 169 below and depicts nohigh-tide feature on the reef. The corresponding sailing directions from 1868 describe Subi
Reef as follows:
Soubie Reef, the south-west end of which is in lat. 10° 53½′ N., long. 114° 4′ E., is thewesternmost danger in this locality. It is an irregular-shaped coral reef, nearly 3½ miles
long, N.E. and S.W., and 2 miles broad, is dry at low water, and has a lagoon into which
there appears to be no passage.356

368. The same conclusion follows from the depiction of Subi Reef in U.S. Defense Mapping Agency
Chart No. 93061, although the Tribunal notes that this chart is a reissued version of U.S.
Hydrographic Office Chart No. 2786, which was simply a copy in 1911 of British Admiralty
Chart No. 1201, which was in turn based the 1867 survey data.357 No high-tide feature on Subi

Reef is depicted on British Admiralty Chart No. 1201 either,358 and the Tribunal is unable toidentify any source suggesting a rock or cay above high water on Subi Reef. Accordingly, theTribunal concludes that Subi Reef is a low-tide elevation.
369. A more complex question, however, is whether Subi Reef lies within 12 nautical miles of ahigh-tide feature, such that it would could serve as a baseline for the territorial sea of thathigh-tide feature pursuant to Article 13(1) of the Convention. Subi Reef lies slightly more than
12 nautical miles from the baseline of Thitu Island, and would not qualify for the purposes of
Article 13(1) for a territorial sea drawn from Thitu Island itself. The 1867 fair chart of the Thitu
Reefs, however, clearly depicts a high-water “Sandy Cay” on the reefs to the west of Thitu
Island. This feature—provided that it, in fact, exists—would lie within 12 nautical miles ofSubi Reef, which would be permitted by Article 13(1) to serve as a baseline for the territorial
sea drawn from Sandy Cay.
370. When questioned on this feature during the hearing, the Philippines argued that Sandy Cay nolonger exists, insofar as it is not depicted in more recent U.S. charts that include the Thitu Reefs
and does not appear in the satellite-derived bathymetry prepared by EOMAP.359
371. As an initial matter, the Tribunal does not believe that any reliable conclusions can be drawn
from the absence of a depiction of Sandy Cay in the 1984 edition of United States Defense
Mapping Agency Chart No. 93044. That chart indicates that the area surrounding the Thitu
Reefs was drawn from the Taiwan Authority of China’s Chart No. 477, which is in turn isdrawn from British Admiralty Chart No. 1201 and the same survey of the Thitu Reefs from1867. 360 The Tribunal sees nothing to suggest that the later U.S. publication reflects new
information on the conditions prevailing on the Thitu Reefs, rather than simply a reduction indetail corresponding with the decreased scale of the chart.
372. On the contrary, the Tribunal notes that a sandbar to the west of Thitu Island is mentioned in allof the recent editions of all relevant sailing directions (including that of the United States):

In the Philippine Coast Pilot:
Pagasa Island . . . A reef lies 1.5 miles NW; irregular depths from 4.6 meters to 14.6
meters (15 to 48 ft) exist in the channel between them. A drying reef with a sand caynear its center, lies 1.2 miles WSW of the above reef. 361(b)

In the Chinese Sailing Directions:
The western side reef basin extends from Zhongye Island to the west approximately
six nautical miles. Aside from some exposed reef on all sides of the shoal, it is all
shallow shoals with irregular water depths.
The Tiexiandong Reef lies
approximately 1.5 nautical miles northwest of Zhongye Island. The water depth
between this reef and Zhongye Island is 4.5 metres 14.6 metres. Approximately 1.3
nautical miles southwest of this coral reef lies Tiexianzhong Reef, and on top of it isa sandbar.362(c)

In the British China Sea Pilot:
A drying reef with a sand cay near its centre 3½ miles WNW. In the middle of thepassage, between this reef and the reef 1¼ miles ENE, leading into the lagoon, there
is a shoal.363(d)

In the U.S. Sailing Directions:
The W reefs of Thitu Island are composed of several drying reefs and shoal patches.
A sand cay lies on one of these drying reefs about 3.5 miles W of the island.364

373. With respect to satellite imagery, the Tribunal remains unconvinced that reliable conclusions
can be drawn from EOMAP’s satellite-derived bathymetry. Moreover, in contrast to a rock or
coral boulder, it is possible that a sand cay may be dispersed by storm action and reform in thesame location after a short while. The absence of a sand cay at a particular point in time is thus
not conclusive evidence of the absence of a high-tide feature. In this instance, the Tribunal
considers that the strong historical evidence of a sand cay on the reefs west of Thitu is to bepreferred, even if the presence of Sandy Cay over time is intermittent. As Subi Reef lies within
12 nautical miles of the reef on which Sandy Cay is located, it could serve as a basepoint for the
territorial sea of Sandy Cay. The Tribunal also notes, however, that even without a high-tidefeature in the location of Sandy Cay, Subi Reef would fall within the territorial sea of Thitu as
extended by basepoints on the low-tide elevations of the reefs to the west of the island.
Accordingly, the significance of Sandy Cay for the status of Subi Reef is minimal.

Mischief Reef

374. Mischief Reef was first surveyed in the 1930s, when it was considered to be of particularinterest as a possible base for flying boats in the event of war. HMS Herald surveyed the reef in1933 and prepared a fair chart at 1:50,000 scale that shows no indication of any rock or feature
above water at high tide. The detailed fair chart of the feature is reproduced as Figure 10 on
page 171 below. HMS Herald also forwarded the following description of the reef in 1933:
An oval-shaped reef about 4½ miles long 100°, and 3 ½ miles broad, with a point on
the southern side.
This reef is awash at Low Water Springs, and is studded with rocks which dry about
2 feet. There is however a rock which dries 5 feet, situated 054°, 1.3 miles from the South
Point.
Very Good shelter is afforded in the lagoon which the reef contains, and boats wereable to work in comparative comfort in spite of a wind force 4. The average depth in the
lagoon is about 4 fathoms, but it is only clear of dangers in the southern half, the remainder
having several patches of coral which either dry at Low Water or have less than 6 feet ofwater over them.
There are three entrances to the lagoon, one on the S.W. side and two on the south.
These have been styled the SOUTH WESTERN ENTRANCE, the SOUTHERNENTRANCE and the BOAT CHANNEL.
(a)
The SOUTH WESTERN ENTRANCE is about .3 cables wide and 2.2 cables
long, with depths of 5 fathoms in the middle. It is however rendered entirely uselessfor anything except small boats by a strip of coral lying across the inside of theentrance, round which there is only a narrow and tortuous channel each side.
(b)
The SOUTHERN ENTRANCE is about ½ cable wide and has depths of over
10 fathoms in it. It is almost straight, and only about 1½ cables long. As with theother two entrances there is a strong tidal stream both at the flood and the ebb, andwhen the channel was examined, even at Neap Tides there was a tide of 1½ knots
running S.W. at the buoy in the middle.
I studied this entrance from the bridge at a distance of half a cable and though
I am of the opinion that I could have taken “HERALD” safely into the lagoon, I did
not consider the risk was justified taking into consideration the dangers known to be
existing inside the lagoon. Nor do I think that this can be called a suitable entrance
for destroyers, since so many factors have to be taken into consideration, i.e.
knowledge of coral reefs, visibility to enable the edges of the coral to be seen, slack
water and absence of which, which during “HERALD’s” visit was across theentrance force 4.
(c)
The BOAT CHANNEL as its name implies is very narrow, and as it reaches
the lagoon is only 20 yards wide, though having a depth of more than 4 fathoms init.
In view of the fact that I did not consider any entrance suitable for ships of destroyer
size, a sketch survey only of Mischief Reef was carried out.
A base was measured by masthead angles between buoys anchored in the South
Western Entrance and Boat Channel, and this was extended to additional buoys in the
lagoon, while the rock drying 5 feet on the S.E. side was also fixed.
The lagoon and entrances were sounded by boats, while ship delineated the outside

167

The South China Sea Arbitration
Award of 12 July 2016of the reef. Deep water extends close up to the reef all round, and ship lay off at night,
lights being placed on two of the buoys.
Star sights were obtained to fix the position of the buoy anchored in the middle ofSouthern Entrance, being adjusted by range and bearing from the ship. The following
results were obtained: . . .
The mean position of the middle of Southern Entrance was therefore accepted to be
Lat. 9° 53′ 42″ N., Long. 115° 30′ 52″ E.365

375. HMS Herald then returned to Mischief Reef in 1938, entered the lagoon, and carried out further
surveys to establish the portions of the lagoon that were clear of submerged dangers.366 This
was then added to the extremely detailed description of Mischief Reef in the Royal Navy’s 1944
Sailing Direction for the Dangerous Ground.367 During the same period, the Imperial Japanese
Navy was also active in surveying Mischief Reef and produced a plan of the feature as part ofImperial Japanese Navy Chart No. 525 – Plans in the Southern Archipelago. 368 It likewiseshows no feature above water at high tide.
376. The Tribunal also notes the description of Mischief Reef in the Chinese Navy Headquarters
sailing directions, which describe only rocks exposed at half tide in the following terms:
Meiji Reef – Located at the northeast part of the Nansha Islands, it is due east of the
Jiuzhang Reefs, and it is approximately 62 nautical miles from Dongmen Reef. The reef
resembles an elliptical shape, and it is an enclosed, independent atoll. The reef flat is
exposed during low tide and is submerged during high tide. The northern part is relatively
wide, and the southern part is relatively narrow. There are dozens of reef rocks on the reef
flat that range in height from 0.6 meters – 1.3 meters. During half-tide, they can be
exposed. The southwest part has three openings to enter the lagoon. The water depth ofthe lagoon is 10 meters – 28 meters, and there are over 50 points of exposed reef flat
scattered throughout. To develop the distant-sea fishing industry, in 1994, China’s fishingauthorities constructed stilt houses and navigational aid facilities on this reef, set up
administrative offices, and created the conditions for distant-sea operations, fishing vessel
safety and production, supply, wind protection, and mooring. Anchoring grounds and thesafe anchoring zone within the Meiji Reef are located at the southwest part of the lagoon.
In the water areas within the joint line connecting the following five points, the water depth
is greater than 10 meters, and the area can provide shelter against level 10 strong winds:(1) 9°53′.1N, 115°30′.6E;(2) 9°53′.1N, 115°31′.6E;(3) 9°54′.2N, 115°31′.5E;(4) 9°55′.0N, 115°30′.5E;(5) 9°53′.6N, 115°30′.2E.369

Despite the absence of any reference to a high-tide feature at Mischief Reef, the Tribunal notes
the reference to a drying rock with a height of five feet above Mean Low Water Springs in
HMS Herald’s description of the reef. China’s Chart No. 18500 similarly depicts a height ofone metre above Mean Sea Level in the location of that rock. Either measurement would atleast be close to the expected level of high water. The Tribunal notes, however, that it does nothave direct evidence of tidal conditions at Mischief Reef and concludes that the clear evidence
from direct observations—to “drying rocks” by HMS Herald and to rocks exposed “during halftide” in the Chinese sailing directions—is more convincing. In light, in particular, of theamount of time spent by HMS Herald in surveying Mischief Reef and the knowledge of tidal
conditions apparent in the above description, the Tribunal considers it inconceivable that ahigh-tide rock or feature could have been overlooked or gone unmentioned.

378. Accordingly, the Tribunal concludes that Mischief Reef is a low-tide elevation.

Second Thomas Shoal

379. Second Thomas Shoal was also first surveyed in the 1930s, although less intensively thanMischief Reef. Second Thomas Shoal was visited by HMS Iroquois in 1931.370 No detailed fairplan of the reef appears to have been produced, but it is depicted in medium scale, without any
indication of a high-tide feature, on the reporting chart of the combined air/sea survey
operations that the Royal Navy undertook in that year to eliminate uncharted dangers and clear
safe lanes through the Spratly Islands. Second Thomas Shoal is also described in the Royal
Navy’s 1944 Sailing Directions for the Dangerous Ground in the following terms:
The northern end of 2nd Thomas shoal lies about 20 miles eastward of Mischief reef; thereef contains a lagoon with depths of about 15 fathoms which may possibly be accessible tovessels of moderate draught, from the eastward. The eastern side of the lagoon has theappearance of having a general depth of about 5 fathoms with a number of isolated drying
patches; the most likely looking passages were examined and found to abound with rocks
with depths of about 2 fathoms but it is considered that a navigable passage probably exists.
The western side of the reef is almost continuous and dries; the only likely passage wasfound, on examination to be foul. There are two or three large rocks near the southern end
which are almost certain to be visible at low water. H.M. Surveying Ship IROQUOIS was
unable to find anchorage in the vicinity. 371

380. The Tribunal notes in particular the description of rocks that “are almost certain to be visible at
low water” and takes this as an indication that no rocks on the reef would be visible at highwater. The Tribunal is also unaware of any more recent evidence suggesting a high-tide feature

on Second Thomas Shoal, including in Chinese Chart No. 18500 or the Chinese Navy
Headquarters sailing directions, which describe the reef in the following terms:
Ren’ai Reef - Located approximately 25 nautical miles north by west of Xinyi Reef, it is an
exposed coral atoll, trending toward south-north, with a distance of approximately
10 nautical miles, the north side is wide while the south side is narrow. The northern halfof the atoll is all connected together, while the southern half is divided into several
segments. There are several solitary exposed reefs on the atoll. The water of the lagoon
inside the atoll is relatively deep, and its south side has several entry-exit points. Slightly
larger vessels can enter and exit. On its northeast side, there is an entry-exit point with awater depth of 27 meters.372

381. Accordingly, the Tribunal concludes that Second Thomas Shoal is a low-tide elevation.
(d)Conclusion

382. Based on the considerations outlined above, the Tribunal reaches the following conclusions
regarding the status of features in the South China Sea. The following features include, or in
their natural condition did include, rocks or sand cays that remain above water at high tide andare, accordingly, high-tide features: (a) Scarborough Shoal, (b) Cuarteron Reef, (c) Fiery Cross
Reef, (d) Johnson Reef, (e) McKennan Reef, and (f) Gaven Reef (North).
383. The following features are, or in their natural condition were, exposed at low tide andsubmerged at high tide and are, accordingly low-tide elevations: (a) Hughes Reef, (b) Gaven
Reef (South), (c) Subi Reef, (d) Mischief Reef, (e) Second Thomas Shoal.
384. The Tribunal additionally records that Hughes Reef lies within 12 nautical miles of the high-tidefeatures on McKennan Reef and Sin Cowe Island, Gaven Reef (South) lies within 12 nautical
miles of the high-tide features at Gaven Reef (North) and Namyit Island, and that Subi Reef lies
within 12 nautical miles of the high-tide feature of Sandy Cay on the reefs to the west of Thitu.

THE STATUS OF FEATURES AS ROCKS/ISLANDS (SUBMISSIONS NO. 3, 5, AND 7)
1.

Introduction

385. In this Section, the Tribunal addresses a further aspect of the Parties’ dispute concerning thestatus of the maritime features and the source of maritime entitlements in the South China Sea.
This dispute is reflected in the Philippines’ Submissions No. 3, 5, and 7, which relate to disputes
about the status of maritime features in the South China Sea under Article 121 of theConvention. Submissions No. 3, 5, and 7 provide as follows:(3)

Scarborough Shoal generates no entitlement to an exclusive economic zone orcontinental shelf;

...
(5)

Mischief Reef and Second Thomas Shoal are part of the exclusive economic zone
and continental shelf of the Philippines;

...
(7)

Johnson Reef, Cuarteron Reef and Fiery Cross Reef generate no entitlement toan exclusive economic zone or continental shelf;

386. Article 121 establishes a regime of islands as follows:
Article 121
Regime of Islands
1.

An island is a naturally formed area of land, surrounded by water, which is above
water at high tide.

2.

Except as provided for in paragraph 3, the territorial sea, the contiguous zone, theexclusive economic zone and the continental shelf of an island are determined inaccordance with the provisions of this Convention applicable to other land territory.

3.

Rocks which cannot sustain human habitation or economic life of their own shallhave no exclusive economic zone or continental shelf.

387. Constituting its own Part VIII of the Convention, the “Regime of Islands” in Article 121
presents a definition, a general rule, and an exception to that general rule.
388. Paragraph (1) contains the definition of an “island” as a “naturally formed area of land,surrounded by water, which is above water at high tide.” This text is unchanged from the1958 Convention on the Territorial Sea and the Contiguous Zone.373
389. Paragraph (2) contains the general rule that islands generate the same entitlements under theConvention as other land territory. Treating naturally formed islands the same as other land373

1958 Convention on the Territorial Sea and the Contiguous Zone, art. 10.

175

The South China Sea Arbitration
Award of 12 July 2016territory was not a new concept, for purposes of generating a territorial sea.374 Additionally, allislands had previously been treated the same with respect to entitlements to the continental
shelf.375 However, the need to distinguish categories of islands had become apparent after the
emergence in the early 1970s of substantially expanded maritime resource zones beyond theterritorial sea, in combination with a new regime for the mineral resources of the seabed beyond
national jurisdiction, recognised as the “common heritage of mankind.” Thus, during the Third
UN Conference, an exception to the rule that all natural islands have the same entitlements was
accepted and incorporated into paragraph (3).376
390. Paragraph (3) acts as a limitation on the general rule in paragraph (2) and provides that “rocks
which cannot sustain human habitation or economic life of their own shall have no exclusive
economic zone or continental shelf.” Article 121 therefore contains a distinction between two
categories of naturally formed high-tide features, which the Tribunal refers to as “fully entitledislands” and “rocks” respectively.
391. The interpretation and application of Article 121 arise in two ways as a result of the Philippines’
Submissions.
392. First, the Philippines seeks specific determinations that certain features are “rocks” within themeaning of Article 121(3) of the Convention. The Philippines’ Submission No. 3 seeks adeclaration that “Scarborough Shoal generates no exclusive economic zone or continental
shelf.” In its Award on Jurisdiction, the Tribunal noted that this Submission reflects a disputeconcerning the status of Scarborough Shoal as a fully entitled island or rock within the meaningof Article 121 of the Convention and that the dispute was not barred from the Tribunal’s
consideration by any requirement of Section 1 of Part XV. The Tribunal noted that this was nota dispute concerning sovereignty over the feature, insofar as the resolution of the Philippines’
Submission would not require the Tribunal to render a decision on sovereignty and insofar as
the objective of the Philippines’ Submission was not to advance its claim to sovereignty overthe feature.377 Accordingly, the question of sovereignty over Scarborough Shoal will remain

entirely unaffected by the Tribunal’s determination.378 The Tribunal also held that this dispute
does not concern sea boundary delimitation, insofar as “a dispute concerning the existence of anentitlement to maritime zones is distinct from a dispute concerning the delimitation of thosezones in an area where the entitlements of parties overlap.”379 The Tribunal thus found that it
had jurisdiction to consider Submission No. 3.380 The Tribunal similarly accepted jurisdiction
over Submission No. 7, in which the Philippines seeks a declaration that “Johnson Reef,
Cuarteron Reef and Fiery Cross Reef generate no entitlement to an exclusive economic zone orcontinental shelf.”381
393. Second, by requesting in Submissions No. 5, 8, and 9 declarations about the Philippines’ own
exclusive economic zone, the Philippines effectively seeks a general determination that all of
the high-tide features in the Spratly Islands are “rocks” for purposes of Article 121(3) of theConvention. The Philippines’ Submission No. 5 requests a declaration that “Mischief Reef andSecond Thomas Shoal are part of the exclusive economic zone and continental shelf of thePhilippines.” As the Tribunal noted in its Award on Jurisdiction, through Submission No. 5,“the Philippines has in fact presented a dispute concerning the status of every maritime feature
claimed by China within 200 nautical miles of Mischief Reef and Second Thomas Shoal,” atleast as to whether such features are fully entitled islands.382 The Tribunal held that Submission
No. 5 reflects a dispute concerning the sources of maritime entitlements in the South China Sea
and whether a situation of overlapping entitlements to an exclusive economic zone or to acontinental shelf exists in the area of Mischief Reef and Second Thomas Shoal. The Tribunal
found that the dispute was not barred from the Tribunal’s consideration by any requirement of
Section 1 of Part XV and is not a dispute concerning sovereignty over the features.383 The
Tribunal also held that this dispute does not concern maritime boundary delimitation:[T]he premise of the Philippines’ Submission is not that the Tribunal will delimit any
overlapping entitlements in order to declare that these features form part of the exclusive
economic zone and continental shelf of the Philippines, but rather that no overlapping
entitlements can exist.384

The Tribunal pointed out, however, that if any other maritime feature claimed by China within
200 nautical miles of Mischief Reef or Second Thomas Shoal were found to be a fully entitled378

delimitation from the Tribunal’s jurisdiction by Article 298 would prevent the Tribunal fromaddressing this Submission.”385 Whether this is the case depends on a determination on thestatus of maritime features in the South China Sea, and accordingly, the Tribunal reserved adecision on its jurisdiction with respect to the Philippines’ Submission No. 5 for considerationin this phase of the proceedings.
394. Similarly, the Tribunal reserved for the present Award any decision on its jurisdiction toconsider the Philippines’ Submissions No. 8 and 9, which seek the following declarations:
8) China has unlawfully interfered with the enjoyment and exercise of the sovereign
rights of the Philippines with respect to the living and non-living resources of its
exclusive economic zone and continental shelf;
9) China has unlawfully failed to prevent its nationals and vessels from exploiting theliving resources in the exclusive economic zone of the Philippines.

395. The Tribunal found in its Award on Jurisdiction that the premise of Submissions No. 8 and 9 isthat no overlapping entitlements exist.386 The Tribunal would only have jurisdiction to consider
the Philippines’ Submissions if it found that only the Philippines were to possesses anentitlement to an exclusive economic zone and/or continental shelf in the areas where China’s
allegedly unlawful activities occurred. The Tribunal accepted that if any maritime feature
claimed by China within 200 nautical miles of these areas were to be a fully entitled island for
purposes of Article 121, “the resulting overlap and the exclusion of boundary delimitation fromthe Tribunal’s jurisdiction by Article 298, would prevent the Tribunal from addressing thesubmissions.”387 The Tribunal was not prepared to make a decision on the status of features as apreliminary matter and reserved decision on its jurisdiction with respect to Submissions
No. 8 and 9 for consideration in this phase of the proceedings.
396. The interpretation and application of Article 121(3) of the Convention is therefore not only
required for the features specified by the Philippines in its Submissions No. 3 and 7, but also for
all significant high-tide features in the Spratly Islands that could impact the Tribunal’s
jurisdiction to decide the matters raised in the Philippines’ Submissions No. 5, 8, and 9.

in their natural form, consist of largely submerged reefs, with small protrusions of coral thatreach no more than a few metres above water at high tide.
398. At paragraph 365, the Tribunal found that Gaven Reef (North) includes a sand cay that is
exposed at high tide, such that Gaven Reef (North) is a high-tide feature. At paragraph 354, theTribunal also found that McKennan Reef is a high-tide feature.
399. The location and description of Mischief Reef and Second Thomas Shoal are also set out above,at paragraph 290. Both features are located within 200 nautical miles of the Philippines’
baselines and fall within the exclusive economic zone claimed by the Philippines under its
Republic Act No. 9522 of 2009. 388 As explained above, whether the Tribunal can make adeclaration that the features are indeed “part of the exclusive economic zone and continental
shelf of the Philippines” as sought by Submission No. 5, would require the Tribunal to rule out
the possibility that any feature claimed by China could generate an entitlement to an exclusive
economic zone that would overlap that of the Philippines at either Mischief Reef or Second
Thomas Shoal. In practice, this would require a finding that none of the Spratly Islands are
fully entitled islands under Article 121 of the Convention.
400. In addition to the foregoing, there are a number of features in the Spratly Islands that are
unequivocally above water at high tide and whose classification may impact the Tribunal’s
decisions with respect to the Philippines’ Submissions No. 5, 8, and 9. Set out in the following
paragraphs are brief descriptions of the location and geographical characteristics of the six
largest features amongst the other high-tide features in the Spratly Islands.
401. Itu Aba is known as “Taiping Dao” (太平岛) in China and “Ligaw” in the Philippines. It is thelargest high-tide feature in the Spratly Islands, measuring approximately 1.4 kilometres inlength, and almost 400 metres at its widest point. Its surface area is approximately 0.43 square
kilometres. It is located at 10° 22′ 38″ N, 114° 21′ 56″ E, lying atop the northern edge of Tizard
Bank, 200.6 nautical miles from the archipelagic baseline of the Philippine island of Palawan
and 539.6 nautical miles from China’s baseline point 39 (Dongzhou (2)) adjacent to the islandof Hainan. The general location of Itu Aba, and that of the other major Spratly Island featuresdescribed in this Section, is depicted in Map 3 on page 125 above. It is surrounded by a coral
reef and shallow water. Itu Aba is currently under the control of the Taiwan Authority of China,
which stations personnel there. There are multiple buildings, a lighthouse, a runway, and port
facilities on Itu Aba.

402. Thitu is known as “Zhongye Dao” (中业岛) in China and “Pagasa” in the Philippines. It
measures approximately 710 metres in length and 570 metres in width. Its surface area isapproximately 0.41 square kilometres. Thitu is located at 11° 03′ 19″ N, 114° 17′ 08″ E, atop
the west-side shoal of two adjacent coral reefs separated by a narrow deep channel. It issurrounded by a drying coral reef. Thitu lies 227.4 nautical miles from the archipelagic baselineof the Philippine island of Palawan and 502.1 nautical miles from China’s baseline point 39(Dongzhou (2)) adjacent to the island of Hainan. Thitu is currently under the control of thePhilippines, which stations personnel there. There are multiple buildings, a lighthouse, and an
airstrip on Thitu.
403. West York Island is known as “Xiyue Dao” (西月岛) in China and “Likas” in the Philippines.
It measures approximately 720 metres in length and 440 metres in width. Its surface area isapproximately 0.21 square kilometres.

It is located atop a coral reef at 11° 05′ 01″ N,

115° 01′ 26″ E, 195.0 nautical miles from the archipelagic baseline of the Philippine island of
Palawan and 524.9 nautical miles from China’s baseline point 39 (Dongzhou (2)) adjacent to theisland of Hainan. It is surrounded by a white sand cay, outside of which there is a coral reefbasin. West York Island is currently controlled by the Philippines, which stations a small
number of personnel there.
404. Spratly Island is known as “Nanwei Dao” (南威岛) in China and “Lagos” in the Philippines. It
measures approximately 390 metres in length and 310 metres in width. Its surface area isapproximately 0.17 square kilometres.

It is located atop a coral bank at 8° 38′ 41″ N,

111° 55′ 15″E, 298.2 nautical miles from the archipelagic baseline of the Philippine island of
Palawan and 584.3 nautical miles from China’s baseline point 39 (Dongzhou (2)) adjacent to theisland of Hainan. It has a margin of white sand and broken coral and is surrounded by drying
rocky ledges. Spratly Island is currently controlled by Viet Nam, which stations personnel
there. There are multiple buildings, a lighthouse, sea walls, a runway, and a pier on Spratly
Island.
405. North-East Cay is known as “Beizi Dao” (北子岛) in China and “Parola” in the Philippines. It
measures approximately 825 metres in length and 244 metres in width. Its surface area isapproximately 0.15 square kilometres. It is located in the larger complex of features known as“North Danger Reef” and lies at 11° 27′ 14″ N, 114° 21′ 14″ E, 239.3 nautical miles from thearchipelagic baseline of the Philippine island of Palawan and 484.3 nautical miles from China’s
baseline point 39 (Dongzhou (2)) adjacent to the island of Hainan. It is surrounded by a belt ofcoral sand and lies on a drying reef. North-East Cay is currently controlled by the Philippines,

180

The South China Sea Arbitration

which stations a small number of personnel there. There are a few structures, including alighthouse, on North-East Cay.
406. South-West Cay is known as “Nanzi Dao” (南子岛) in China and “Pugad” in the Philippines. It
measures approximately 670 metres in length and 283 metres in width. Its surface area isapproximately 0.15 square kilometres. Like North-East Cay, it is located in the larger complex
of features known as “North Danger Reef” and lies at 11° 25′ 49″ N, 114° 19′ 52″ E,
239.6 nautical miles from the archipelagic baseline of the Philippine island of Palawan and484.8 nautical miles from baseline point 39 (Dongzhou (2)) adjacent to the island of Hainan. It
is surrounded by a drying reef. South-West Cay is currently controlled by Viet Nam, which
stations personnel there. There are multiple buildings, a lighthouse, seawalls, and port facilities
on South-West Cay.
407. Other high-tide features claimed by China atop coral reefs in the Spratly Islands are smaller insize than the above-described features, with surface areas of less than 0.14 square kilometres,
but present similar characteristics. The Tribunal has examined Amboyna Cay, Flat Island,
Loaita Island, Namyit Island, Nanshan Island, Sand Cay, Sin Cowe Island, and Swallow Reef
for evidence of human habitation or economic life, but does not consider it necessary to discussthem individually. The Tribunal considers that if the six largest features described above are all
to be classified as rocks for purposes of Article 121(3) of the Convention, the same conclusion
would also hold true for all other high-tide features in the Spratly Islands.

The Philippines’ Position

408. The Philippines submits that Scarborough Shoal and all of the high-tide features in the Spratly
Islands are properly characterised as “rocks” under Article 121(3) of the Convention.389(a)Interpretation of Article 121(3)409. Based on a review of the origins and negotiating history, the Philippines discerns “certain clear
conclusions regarding the object and purpose of the provision.”390 In particular, the Philippines
argues that the records of the Third UN Conference reflect overwhelming opposition to theprospect of granting very small, remote, and uninhabited islands extensive maritime zones thatwould unfairly and inequitably impinge on other States’ maritime space and on the area of

The South China Sea Arbitration
Award of 12 July 2016

international seabed.391 The Philippines concludes that Article 121(3) of the Convention wasinserted as a result of the drafters’ belief “that it would be unjustifiable and inequitable to allow
tiny and insignificant features, which just happen to protrude above water at high tide, togenerate huge maritime entitlements to the prejudice of other proximate coastal states withlengthy coastlines and significant populations, or to the prejudice of the global commons
beyond national jurisdiction.”392 In other words, the object and purpose of Article 121(3) is to“avoid perverse effects of the major extensions of coastal State jurisdiction beyond theterritorial sea.”393
410. The Philippines’ makes the following arguments with respect to the interpretation of particularelements of the text of Article 121(3).
411. First, it submits that the meaning of “rock” must not be limited in terms of geological orgeomorphological characteristics. Thus, protrusions above water that are composed of coral,mud, sand, or soil may constitute rocks within the meaning of Article 121(3) of theConvention.394
412. Second, the Philippines acknowledges that size alone is not determinative of the status of afeature as a rock pursuant to Article 121(3). Nevertheless, it points to the negotiating history
and certain State practice to suggest that it would be reasonable to conclude that a high-tidefeature with a high-tide area “less that one km2 could be regarded as sufficiently small to createa presumption that it is not genuinely able to sustain human habitation and economic life of its
own.”395 The Philippines’ expert, Professor Schofield, states that while size is not dispositive,
the physical extent of a feature can be a “pertinent factor” because, in many instances, a“negligible physical dimension will preclude the possibility of a feature being able to sustain
human habitation or an economic life associated with it, because of the limited space andresources for habitation and economic life.”396
413. Third, the Philippines notes that the term “cannot” refers to the capacity or potential of thefeature to sustain human habitation or economic life, and not to an enquiry into whether thefeature actually does now sustain, or has ever in the past sustained, human habitation or
economic life. Even so, the Philippines argues that the fact that a feature has historically been

uninhabited and has sustained no economic life would constitute powerful evidence of its lackof capacity to do so.397
414. Fourth, the Philippines argues that the words “sustain human habitation” must mean that, innaturally occurring conditions, a feature can “support a stable group of human beings across asignificant period of years,” by providing fresh water, food and living space and materials forhuman shelter.398 Such meaning, the Philippines argues, is supported by the context of therequirement that an island be “naturally formed” in the definition of an island in Article 121(1).
The object and purpose of the provision would be undermined if distant States could introduce
technology, artificial additions, and external supplies to support human habitation.
415. Fifth, the use of “on their own” in connection with features sustaining an economic life must,
according to the Philippines, plainly mean “that the feature itself has the ability to support anindependent economic life without infusion from the outside.”399 It would need to be “local andnot imported”; “real and not contrived,” though “100 percent self-sufficiency is not required.”400
416. Sixth, “economic life” is not to be equated simply to economic value. Rather it requires some
activity that presupposes more than the existence of a resource or the presence of an installationof an economic nature. The feature must, in its naturally formed state, have the capacity todevelop sources of production, distribution, and exchange sufficient to support the presence of astable human population.401 The Philippines submits that the capacity of a feature to sustain an
economic life of its own may be determined by reference to the resources of the territorial sea,
but not beyond. According to the Philippines, if resources in the waters beyond the territorial
sea could be relied upon, the result would be circular and illogical and entail that the sea
dominates the land.402
417. The Philippines argues that in order to be a fully entitled island, a feature must be capable bothof sustaining human habitation and of sustaining an economic life of its own. It submits that thegrammatical context of the word “or” in Article 121(3) creates, through a double negative, acumulative requirement. This cumulativeness is, according to the Philippines, underscored bylogic because the concepts of sustained “human habitation” and “economic life” are interrelated,

and it is difficult to conceive of one without the other. 403

Any alternative reading of

Article 121(3) would have undesirable consequences: tiny specks of features incapable ofhuman habitation could generate entitlements to vast ocean spaces merely with the “use [of]factory ships or oil platforms or even casinos built on stilts.”404 That said, the Schofield Reportapplied a disjunctive test,405 and both the Philippines and its experts submit that the result in thiscase would be the same whether the Tribunal required only one or both of the requirements of“human habitation” and “economic life” to be satisfied for a feature to be a fully entitledisland.406
418. The Philippines points to various commentaries to support its view that installation of a militarypresence on a rock, serviced from the outside, does not establish that the feature is capable ofsustaining human habitation or has an economic life of its own.407 It cites further support fromthe practice of Viet Nam and Malaysia, who have externally sustained troops stationed onhigh-tide features in the Spratly Islands, yet do not claim them as fully entitled islands. The
Philippines’ expert, Professor Schofield, also explained his view that the lack of an“indigenous” population—meaning a community who decided to settle on a feature of their own
accord, as distinct from government or military personnel—may indicate that a feature cannot
sustain human habitation.408
419. The Philippines argues that the State practice on the interpretation of Article 121(3) isinconsistent, but States generally accept that small, uninhabited, barren outcrops should not
generate full maritime zones, citing in particular (a) the United Kingdom’s renunciation of its
200-nautical-mile fishery zone around Rockall, in connection with its accession to the403

Convention, and (b) China’s own protests at Japan’s submission for an extended continental
shelf relating to Oki-no-Tori-shima.409
420. Recognising that the present case is not one of maritime delimitation, the Philippines alsosuggests that the Tribunal could seek useful guidance from the approach of international courts
and tribunals in the delimitation context.410 The Philippines notes that features of comparable
nature, small size, and remoteness to those in the Spratlys have been “enclaved”, that is, given
no more than a 12-nautical-mile territorial sea, in a number of cases, including Maritime
Delimitation in the Black Sea, Territorial and Maritime Dispute (Nicaragua v. Colombia), theDubai/Sharjah Border Arbitration, Delimitation of the Continental Shelf Between the United
Kingdom of Great Britain and Northern Ireland, and the French Republic and Delimitation of
the Maritime Boundary Between Bangladesh and Myanmar in the Bay of Bengal. 411 Suchenclaving has been done in order to achieve an “equitable result” in drawing a boundary line,
taking into account circumstances that are the same as those that “determine whether an insularfeature is a ‘rock’ under Article 121(3).” 412 According to the Philippines, the jurisprudence“make[s] absolutely clear” that “in any future boundary delimitation in the South China Sea . . .
all of the Spratly high-tide features would be enclaved, and in no case given more than a
12-mile territorial sea.”413
421. The Philippines expresses concern that if any of the Spratly Islands were found to be fully
entitled islands and China remained determined to avoid any form of legally binding
adjudication or arbitration of the boundary, the dispute could be “frozen”. By contrast, thePhilippines argues, a determination that the features were only rocks would reduce the incentive
to “flex muscles and demonstrate sovereignty over minuscule features” that generate amaximum entitlement of 12 nautical miles, and thus contribute to the “legal order and themaintenance of peace in the South China Sea.”414 The Philippines appealed to the Tribunal’s

mandate to “promote the maintenance of legal order in respect of the relevant maritime areas,
and the avoidance or reduction of threats to international peace and security that inevitably
would emanate from a situation of such legal uncertainty,” in accordance with the UN Charterand the Preamble of the Convention.415
422. Ultimately, the Philippines submits that the test of whether a feature constitutes a “rock” for the
purposes of Article 121(3) involves a “question of appreciation” in light of the naturalcharacteristics of a given feature. It should be an objective test, in the sense that it should not be
determined by any State’s own subjective assertions, but on the basis of evidence derived fromobservations by identifiable, authoritative, and credible sources. 416 Beyond the essentials offood, drinkable water, and shelter, certain factors, such as size, prior civilian habitation, and thepresence of productive soil, flora, and fauna might all be informative but not determinative. 417
For the Philippines, the interpretation and application of Article 121(3) thus requires “case-bycase determinations on the basis of the available facts, including the particular geographicalcontext.”418(b)Application to Features Identified in Submissions No. 3 and 7423. The Philippines and its experts submit that all four of the high-tide features identified in its
Submissions No. 3 and 7—Scarborough Shoal, Johnson Reef, Cuarteron Reef, and Fiery Cross
Reef—are indisputably Article 121(3) rocks.419 Noting their tiny dimensions and the low height
to which they protrude above water, the Philippines draws similarities between these features
and Rock No. 32 of Colombia’s Quitasueño,420 which was held by the International Court ofJustice in Territorial and Maritime Dispute (Nicaragua v. Colombia) to be a rock for the
purposes of Article 121(3).421
424. Relying largely on aerial and satellite photography, as well as the Philippine, Chinese, UK, andU.S. sailing directions, the Philippines considers all four features to be rocks incapable ofsupporting human habitation.422 According to the Philippines, there is no evidence of drinkable

water, food, or shelter materials on any of the four features.423 The Philippines observes that
other small, barren, and uninhabited protrusions like Quitasueño (Colombia), Rockall (UK),
Filfla (Malta), and Jabal al-Tayr and Zubayr (Yemen) have been treated by international courts
and tribunals as rocks or features unworthy of being taken into account in delimitations.424
425. Finally, the Philippines stresses that neither China’s recent island construction nor its earlier
installation of small artificial structures atop coral reefs, manned by government personnel
sustained entirely with external resources, can convert these features into fully entitledislands.425(c)Application to Other Maritime Features

426. The Philippines concedes that the three largest features, Itu Aba, Thitu, and West York, “differ
from Scarborough Shoal, Johnson Reef, Cuarteron Reef, and Fiery Cross Reef in terms of theirarea, natural conditions and small population,” but submits that these differences are “too minor
to elevate such small, insignificant and remote features” to the status of fully entitled islands.
According to the Philippines, none of the features in the Spratly Islands is capable, based on its
own natural elements, of sustaining both human habitation and economic life of their own.426
i.

Itu Aba

427. At the Hearing on the Merits, the Philippines summarised its view of the evidence concerning
Itu Aba as follows:(1) there is no fresh water on Itu Aba suitable for drinking or capable of sustaining ahuman settlement;(2) there is no natural source of nourishment on the feature capable of sustaining a humansettlement;(3) there is no soil on Itu Aba capable of facilitating any kind of agricultural productionthat could sustain human habitation;(4) there has never been a population on the feature that is indigenous to it;(5) excluding military garrisons, there has never been human settlement of any kind on Itu
Aba;(6) there was not even a military occupation prior to World War II

Award of 12 July 2016(7) the Taiwanese troops that are garrisoned at Itu Aba are entirely dependent for theirsurvival on supplies from Taiwan, and apart from sunlight and air, they derive nothing
they need from the feature itself;(8) no economic activity has been or is performed on Itu Aba. 427

428. The Philippines points particularly to the lack of drinkable water and the fact that the Taiwan
Authority of China has had to compensate for this through construction of desalination plants.428
The Philippines relies on a 1994 scientific study on “The Flora of Taipingtao (Aba Itu Island)”(the “1994 Study”), prepared based on a field inspection by Taiwanese botanists whose work
was financed by the Taiwan Authority of China, and submits that its conclusions on water, soil,
and vegetation demonstrate the impossibility of sustaining human habitation.429
429. The Philippines acknowledges that in the nineteenth century, British vessels observed thepresence of fishermen on Itu Aba. But according to the Philippines, the presence of thefishermen is conveyed as “very primitive and temporary” and “short-lived” and the fishermen’s“inability to settle on Itu Aba only confirms the feature’s uninhabitability.”430 The Philippines
notes that the Japanese were the first to use the feature as a military base, during the Second
World War, but recalls that military occupation for the sole purpose of asserting sovereignty
does not suffice to prove capacity to sustain human habitation or an economic life. The
Philippines also observes that all attempts to extract commercial quantities of guano from theSpratlys failed.431

“support [its] conclusion that the feature is a rock as defined in Article 121(3).” 432 The
Philippines notes that the 1868 China Sea Directory describes Itu Aba as being “almost
completely devoid” of natural resources and frequented by fishermen having their permanent
residence in Hainan, not on Itu Aba itself. 433 The Philippines considers that the documents
obtained by the Tribunal confirm that subsequent Japanese attempts to cultivate or settle theisland were either unsuccessful or exclusively “military in nature”;434 that the feature remained
uninhabited, excepting a “brief” post-war Taiwanese occupation from 1946 to 1950; 435 and that
Itu Aba lacked both fresh water and high-quality soil.436
431. The Philippines likewise submits that various historical documents obtained by the Tribunal
from the Bibliothèque Nationale de France and the Archives Nationales d’Outre-Mer andprovided to the Parties for comment “confirm that Itu Aba and the other insular features
discussed in the French documents . . . lack the natural resources, including fertile soil andfreshwater, necessary to sustain human habitation or economic life.”437 The Philippines notesthat the Division Botanique à l’Institut des Recherches Agronomiques de L’Indochine visited Itu
Aba in 1936 and recorded that it was covered only partly with soil, and that the rest was coralsand, guano and natural phosphate, and that the vegetation was very poor.438 According to thePhilippines, “[n]one of the native species cataloged by the visiting botanists are agricultural
crops capable of supporting human habitation” as they are “either inedible or have only limited
nutritional value.” 439 On this basis, the Philippines argues that Itu Aba is “incapable ofsustaining agricultural production.”440 The Philippines also points to “the lack of any discussionof freshwater in any of the documents.” 441 Furthermore, the Philippines considers that the432

The South China Sea Arbitration
Award of 12 July 2016archival material confirms that Itu Aba “had no permanent human population” and was notrecognised as “having any economic value.”442
432. When asked at the Hearing on the Merits to comment on more recent materials concerning Itu
Aba published by the Taiwan Authority, the Philippines noted that two books claimed only theexistence of “groundwater wells” without describing the water’s drinkability and depicted a“skimming well”, which is used to extract relatively fresh water from the upper zone of a
fresh-saline aquifer in freshwater lenses.443 According to the Philippines:
Taiwan’s fancy photographs of a paved airstrip, communications equipment and various
buildings change nothing. They amount to no more than a manmade façade, a Potemkin“island”. . . whose artifices serve mainly to divert attention from the true nature of thefeature: a remote dot of exposed coral that is incapable naturally of sustaining any humanhabitation or economic life of its own. 444

433. The Philippines recalls that the Taiwan Authority never claimed maritime entitlement beyond
12 nautical miles from Itu Aba until after the Philippines initiated this arbitration.445
434. The Philippines suggests that the Taiwan Authority’s more recent public declarations andpublication of video of conditions on Itu Aba through the internet are attempts by the Taiwan
Authority to rebut the Philippines’ case and “put its best foot forward” in the context of thisarbitration. 446 The Philippines urges the Tribunal to treat with great caution the claimspresented by the Taiwan Authority as being unsupported by actual evidence, created specificallyfor the purpose of litigation, and based on statements by officials with an interest in the outcomeof the proceedings. The Philippines asserts that the Taiwan Authority and China’s interests are“aligned” in maximising Itu Aba’s potential maritime entitlements.447

The South China Sea Arbitration
Award of 12 July 2016435. According to the Philippines, earlier statements of Taiwanese officials and academics reference
the need for regular external supplies to sustain the garrison and thus undermine the Taiwan
Authority’s claim that Itu Aba has the natural resources to be self-sufficient.448 The Philippines
observes that the first civilian to register residence on the island only did so in 2016 in the midstof the Taiwan Authority’s public relations campaign to “aggrandize” the feature.449
436. The Philippines also rejects the Taiwan Authority’s claims about “rich supply of groundwater”
from five wells on the island. It suggests that the Taiwan Authority’s failure to refer to the 1994
Study must “be taken to mean that [it] has no effective response.”450 The Philippines recalls thatfour of the wells are “skimming wells”. According to the Philippines, even the carefully
skimmed water from the best well produces limited amounts of water that verges close tominimal potability.451 The Philippines submits an expert analysis of Itu Aba’s groundwater
resources by Dr. Ryan T. Bailey.452 Taking into account the size of the island, its composition,and the annual rainfall, Dr. Bailey concludes that “any freshwater lens on Itu Aba is, at best, afragile source of freshwater that, if disturbed or affected by periods of low rainfall, would
become completely exhausted.”453 The Philippines concludes that “even if Itu Aba does have amarginal freshwater lens beneath it, which is questionable and unsupported by any actual
evidence tendered by Taiwan, it requires constant and substantial supplementation by artificial
means just to keep Taiwan’s few troops alive.”454
437. The Philippines also takes issue with the Taiwanese claims concerning soil on Itu Aba, which itsays are contradicted by the 1994 Study. The Philippines submits from Dr. Peter Motavalli an
Expert Report on Soil Resources and Potential Self-Sustaining Agricultural Production on Itu
Aba and a Second Supplemental Expert Report on Soil Resources and Potential Self-Sustaining
Agricultural Production on Itu Aba. 455 Dr. Motavalli describes the calcareous soils andhighlights several constraints for self-sustaining agricultural production on Itu Aba,456 queries

whether the soil for vegetables might have been introduced, and notes the problems of pests anddiseases.457 In his supplemental export report, Dr. Motavalli provides observations on a 1936
report by the Division Botanique à l’Institut des Recherches Agronomiques de L’Indochine
obtained by the Tribunal from the National Library of France and concludes that:the 1936 Report’s analysis of an “[a]verage soil sample” on Itu Aba confirms my priorconclusions that the soil is sandy, calcareous, has a high pH, and lacks some major
nutrients. In light of these characteristics, I conclude that Itu Aba’s soil resources cannot
sustain a meaningful level of agricultural production without the use of soil amendments
and other major interventions.458

The Philippines expresses doubts about the agricultural capability of Itu Aba to even feed asingle person.
438. The Philippines considers the Taiwan Authority’s submission of additional materials concerning
the status of Itu Aba, such as a “Position Paper on ROC South China Sea Policy Republic ofChina (Taiwan)” and an “Amicus Curiae Submission by the Chinese (Taiwan) Society ofInternational Law,” similarly unavailing. Even on the basis of the materials submitted by the
Taiwan Authority, the Philippines argues that Itu Aba has neither a longstanding history ofhuman habitation nor possesses sufficient fresh water and soil resources to sustain such a
population, and notes that any attempts made to carry out “meaningful economic activity” on Itu
Aba uniformly “ended in failure.”459 The Philippines attaches a supplemental expert report by
Dr. Ryan T. Bailey, who questions the Taiwan Authority’s measurements of water quality andsalt concentration on Itu Aba’s wells. 460 The Philippines considers the historical accountpresented by the Taiwan Authority relevant insofar as it undermines China’s claim to exclusive
rights within the ‘nine-dash line’.461
439. Finally, the Philippines objects to the Taiwan Authority’s arguments that if the Tribunal were tofind Itu Aba to be a rock, “serious issues could arise, as several nations would no longer be able
to claim EEZs of certain islands.”462 The Philippines notes that the Taiwan Authority’s position

is undermined by China’s own stance with respect to Japan’s claim to an exclusive economic
zone around Oki-no-Tori-shima. It also recalls that restraining excessive State claims is one ofthe purposes of Article 121(3) and international law in general.463 The Philippines echoes its
appeal to the Tribunal to avoid a situation of dangerous uncertainty:
Finding that a tiny feature like Itu Aba could generate entitlement to a continental shelf and
EEZ would intensify the already dangerous sovereignty disputes in the area (and potentiallyelsewhere in the world) and encourage further damage to the delicate natural environmentof the South China Sea by encouraging States to undertake further efforts to solidify theirclaims. Such an outcome would be inconsistent with the core objects and purposes of theConvention, namely to ‘promote the peaceful uses of the seas and oceans, the equitable andefficient utilization of their resources, the conservation of their living resources, and thestudy, protection and preservation of the marine environment.’ It would be equallyinconsistent with the central object of Part XV: the peaceful settlement of disputes. 464

440. The Philippines submits that there are two ways for the Tribunal to avoid these threats to peace:
either find Itu Aba to be a rock, or “enjoin both Parties, pending agreement on delimitation,from exercising any rights in respect of any feature in the Spratly Islands beyond 12 [miles].”465
ii.

Thitu, West York, and Other High-Tide features

441. The Philippines, which has occupied Thitu since 1970, recalls that it only claims a
12-nautical-mile territorial sea from Thitu and considers it to be a rock for purposes of
Article 121(3). The Philippines notes that there is a well on Thitu that contains “brackish but
drinkable water,” but the water must be filtered for safe consumption. The local population on
Thitu was transplanted there and has been maintained by the Philippine Government since 2001.
It is only possible to grow vegetables there because soil is continually imported from Palawan
and supplies are shipped by naval vessel to personnel monthly.466 The Philippines argues thatwithout the “umbilical cord” of the Philippines’ support, Thitu is—like Itu Aba—incapable ofsustaining the habitation of even the small community that the Philippines maintains there. 467
The Philippines’ experts take the same view.468
442. The Philippines notes that, at 0.21 square kilometres, West York is even smaller than Thitu and
Itu Aba. Like Thitu, the Philippines considers West York to be a “rock” unable to sustain
human habitation or economic life. According to the Philippines, there is no potable water and463

agriculture is impossible because the salinity of the water retards growth of introduced plants.
There is no population, only a small observation post staffed by a few soldiers sustained byoutside supplies. 469 Accordingly, the Philippines submits that West York does not haveconditions sufficient to sustain human habitation or an economic life.
443. The Philippines and its experts make similar submissions about the status of other high-tidefeatures in the Spratly Islands, including North Danger Reef, South Danger Reef, Nanshan
Island, Sand Cay, Loaita Island, and Swallow Reef.470
444. The Philippines considers the materials obtained by the Tribunal from the archives of the UK
Hydrographic Agency to confirm that the Philippines has correctly categorised the remaining
features as “rock[s] as defined in Article 121(3).”471 The Philippines notes that the China Sea
Directory fails to mention the existence of any inhabitants on the features,472 with other reports
describing only the faintest traces of human presence, such as wells with “brackish” water, as on
Loaita Island,473 or foundations of a “small hut”, as in the case of Thitu.474 The Philippines also
notes the near-complete lack of vegetation on the features in question.475
445. Finally, the Philippines also considers that documents obtained by the Tribunal from France’s
National Library and National Overseas Archives confirm that “the other features in the South
China Sea are incapable of sustaining human habitation or economic life of their own.”476 In
this regard, the Philippines cites a 1949 internal French Government report which states thatthese “islands have no fixed population and carry only stunted vegetation.”477

China’s Position

446. In connection with the Philippines’ Submissions No. 3, 5, and 7, China’s Position Paper statesthat “the Philippines is putting the cart before the horse by requesting the Arbitral Tribunal todetermine, even before the matter of sovereignty is dealt with, the issue of compatibility of
China’s maritime claims with the Convention.”478 China has repeated this position in more
recent statements, arguing that
According to international law, the entity that enjoys maritime entitlements is the State thatowns maritime features, rather than the maritime features themselves. Each maritime
entitlement is explicitly tied to the State that it belongs to. In its provisions on territorialsea, contiguous zone, exclusive economic zone, and continental shelf, the UNCLOS
explicitly grants the maritime entitlements to the “coastal State” of relevant maritime zones
in question. It is meaningless to indulge in the empty talk on the legal status andentitlements of maritime features without making a preliminary decision on who is the“coastal State” and in separation from State sovereignty. The legal status and entitlementsof maritime features do not constitute actual disputes in themselves, and there is noprecedent in international law deciding otherwise. 479

447. The Tribunal rejected that argument in its Award on Jurisdiction, 480 holding that it was notnecessary to first decide questions of sovereignty and “that it is entirely possible to approach thePhilippines’ Submissions from the premise . . . that China is correct in its assertion ofsovereignty over Scarborough Shoal and the Spratlys.”481
448. China also objected that the Philippines had selected to seek specific determinations on thestatus of only nine maritime features, principally those on which China currently maintains apresence.

China posited that “[i]t is plain that, in order to determine China’s maritime

entitlements based on the Nansha Islands under the Convention, all maritime featurescomprising the Nansha Islands must be taken into account.” 482 China pointed out that thePhilippines had omitted from its requested determinations the “largest island in the Nansha
Islands, Taiping Dao, which is currently controlled by the Taiwan authorities of China,” as well
as features that the Philippines itself occupies.483

Award of 12 July 2016449. China considers that it “has, based on the Nansha Islands as a whole, territorial sea, exclusive
economic zone, and continental shelf,” 484 but has not explicitly set out its position on theapplication of Article 121(3) to each of the maritime features identified in the Philippines’
Submissions. China’s general silence in this regard can be contrasted with (a) the positions ofStates such as Viet Nam, Indonesia, and the Philippines485 that high-tide features in the Spratly
Islands are “rocks” for purposes of Article 121(3) and should only be entitled to a 12-nauticalmile territorial sea; (b) the position implied in Malaysia and Viet Nam’s Joint Submission to the
CLCS that sets out official coordinates for the 200-nautical-mile limit of the continental shelvesof the two States, drawn only from basepoints adjacent to Borneo and the mainland of Viet Nam
and not from any feature in the Spratlys;486 and (c) recent assertions by the Taiwan Authoritythat Itu Aba “indisputably qualifies as an ‘island’ according to the specifications of Article 121. . . and can sustain human habitation and economic life of its own” and “is thus categoricallynot a ‘rock’.”487
450. Nevertheless, China’s positions on the status of some features, as well as the meaning of
Article 121 generally, can be discerned from its own laws, diplomatic exchanges, and publicstatements.

China’s Statements on the Meaning of Article 121(3)451. China has made diplomatic representations that reveal its position and “serious concerns” about
the operation of Article 121(3) in practice, notably in the context of protesting Japan’s
November 2008 claim of an extended continental shelf from Oki-no-Tori-shima.488 Oki-noTori-shima is an atoll, located in the western Pacific Ocean between Okinawa and the Northern
Mariana Islands, of which only two small portions naturally protrude above water at high tide.
452. In a Note Verbale to the UN Secretary-General dated 6 February 2009, submitted in response to
Japan’s submission to the CLCS concerning the limits of the extended continental shelf, China
expressed its view that when States exercise their rights to establish the outer limits of theircontinental shelf beyond 200 nautical miles, they “shall also have the obligation to ensure
respect for the extent of the International Seabed Area . . . which is the common heritage ofmankind, and not to affect the overall interests of the international community as a whole.”489
China emphasised that all States “shall implement the Convention in its entirety and ensure theintegrity of the Convention, in particular, ensure that the extent of the Area is not subject to any
illegal encroachment.”490 With respect specifically to Oki-no-Tori-Shima, China went on tostate as follows:
It is to be noted that the so-called Oki-no-Tori Shima Island is in fact a rock as referred toin Article 121(3) of the Convention. Therefore, the Chinese Government wishes to draw
. . . attention . . . to the inconformity with the Convention with regard to the inclusion of therock of Oki-no-Tori in Japan’s Submission.
Article 121(3) of the Convention stipulates that, “Rocks which cannot sustain humanhabitation or economic life of their own shall have no exclusive economic zone orcontinental shelf.” Available scientific data fully reveal that the rock of Oki-no-Tori, on its
natural conditions, obviously cannot sustain human habitation or economic life of its own,
and therefore shall have no exclusive economic zone or continental shelf. Even less shall it
have the right to the extended continental shelf beyond 200 nautical miles.491

453. A few months later, in advance of the 19th Meeting of States Parties to the Convention in
May 2009, China proposed that the agenda include a supplementary item entitled “International
Seabed Area as the common heritage of mankind and article 121 of the United Nations

Convention on the Law of the Sea.”492 In an explanatory note to its proposal, China recalled thegeneral obligation of good faith in Article 300 of the Convention and stated that in submissions
concerning the outer limits of the continental shelf:[C]oastal States should comply fully with the Convention, taking into account the overall
interests of the international community, and should not interpret the Convention in abiased way, nor put their own interests above the overall interests of the international
community, nor encroach upon the Area as the common heritage of mankind.493

454. China noted that most States had abided by the provisions of the Convention and made “serious
efforts to safeguard the overall interests of the international community when claiming theirrights.” However, China observed that:
there is also some case in which the Convention is not abided by, for example, claims on
the continental shelf within and beyond 200 nautical miles with an isolated rock in theocean as base point. Recognition of such claim will set a precedent which may lead to
encroachment upon the high seas and the Area on a larger scale. Therefore, theinternational community should express serious concerns on this issue. 494

455. China quoted the provisions of Article 121(3) and stated:
How to implement this provision relates to the interpretation and application of importantprinciples of the Convention, and the overall interests of the international community, andis a key issue for the proper consideration of relevant submission concerning the outer
limits of the continental shelf, and the safeguarding of the common heritage of mankind. 495

China argued that there was a need for “some appropriate guidelines” on the issue of the legal
implication of Article 121 on the protection of the common heritage of mankind.
456. During the 15th Session of the International Seabed Authority in June 2009, China raised theissue of rocks under Article 121(3) in the context of particular continental shelf submissions and“argued that the International Seabed Authority was the right forum to discuss matter since it

had the mandate to protect the common heritage of mankind.”496 Referring to Article 121(3),the Chinese representative “urged member States to be guided by the letter and spirit of theConvention to avoid any encroachment on the common heritage of mankind.”497
457. China reiterated its position on Oki-no-Tori-shima in a 3 August 2011 Note Verbale to the
UN Secretary General, after Korea had also registered protest. China stated that it “consistently
maintains that, the rock of Oki-no-Tori, on its natural conditions, obviously cannot sustain
human habitation or economic life of its own” and therefore under Article 121(3), the rock ofOki-no-Tori “shall have no exclusive economic zone or continental shelf.” 498 China went on tostate that:the application of Article 121(3) of the Convention relates to the extent of the International
Seabed Area as the common heritage of mankind, relates to the overall interests of theinternational community, and is an important legal issue of general nature. To claim
continental shelf from the rock of Oki-no-Tori will seriously encroach upon the Area as thecommon heritage of mankind.499

458. Through the statements recounted above, China has demonstrated a robust stance on theimportance of Article 121(3). It has repeatedly alluded to the risks to “the common heritage ofmankind” and “overall interests of the international community” if Article 121(3) is notproperly applied to small features that on their “natural conditions” obviously cannot sustain
human habitation or economic life of their own. China has not, however, assessed those factors
in any specific analysis of most of the individual features in the South China Sea, as discussed
below.

460. In China’s 1958 Declaration of the Government of the People’s Republic of China on China’s
Territorial Sea, China declared a twelve mile nautical sea from “all territories . . . including . . .
the Zhongsha Islands.”501 China’s 1992 Law on the Territorial Sea and the Contiguous Zone
also included the Zhongsha Islands in China’s territorial land which generated a 12-nauticalmile territorial sea.502
461. In conjunction with its ratification of the Convention, on 7 June 1996, China declared an
exclusive economic zone of 200 nautical miles and a continental shelf in accordance with theprovisions of the Convention and reaffirmed its sovereignty over the islands listed in Article 2of its 1992 Law on the Territorial Sea and the Contiguous Zone.503 According to China’s 1998
Exclusive Economic Zone and Continental Shelf Act, China’s exclusive economic zone andcontinental shelf are to be measured 200 nautical miles from “the baselines from which thebreadth of the territorial sea is measured.”504 China has not, however, published “the baselines
from which the breadth of the territorial sea” for Scarborough Shoal is measured. While China
has stated that it is entitled to an exclusive economic zone and continental shelf from the Spratly
Islands, under the relevant provisions of the Convention and the above-referenced legislation, it
has made no such claim specifically with respect to Scarborough Shoal.505
462. Various statements of Chinese Foreign Ministry officials, however, indicate that China
considers Scarborough Shoal to be at least a high-tide feature within the definition of “island”
under Article 121(1) of the Convention. For example, on 22 May 1997, a press briefing entitled“Chinese Foreign Ministry Statement regarding Huangyandao” stated:

The South China Sea Arbitration
Award of 12 July 2016

Huangyan Dao has always been Chinese territory and its legal position has been longdetermined. According to Article 121 of the UNCLOS, Huangyandao is surrounded bywater on all sides and is a natural dry land area that is higher than the water level duringhigh tide; it is not a shoal or submerged reef that does not rise above the water all year
round.
...
The Philippines has never challenged the position that Huangyandao is China’s territory.
Recently, the Philippine side suddenly claims that it has maritime jurisdiction over
Huangyandao because the island is in the 200 nm EEZ of the Philippines. This position
violates the principles of international law and the UNCLOS. . . . The issue ofHuangyandao is an issue of territorial sovereignty; the development and exploitation of the
EEZ is a question of maritime jurisdiction, the nature of the two issues are different . . . .
According to international law, under a situation where is an overlapping of EEZ’s among
concerned countries, the act of a country to unilaterally proclaim its 200 EEZ is null andvoid. The scope of the EEZ’s of the Philippines and China should be resolved throughnegotiations based on the principles and regulations of international laws.506

463. The above statement expresses China’s view that Scarborough Shoal is an island, without
engaging in an analysis of whether it might be a rock for purposes of Article 121(3) of theConvention. China does, however, allude to a situation of two “overlapping EEZ[]s” rather thana situation of an exclusive economic zone overlapping only with a territorial sea.

As

Scarborough Shoal lies more than 200 nautical miles from any other high-tide feature claimedby China, the reference to “overlapping EEZ[]s” suggests that China may consider ScarboroughShoal to be entitled to an exclusive economic zone.
464. In July 1998, according to a record of the “10th Philippines-China Foreign Ministry
Consultations” held in Manila on 30 July 1998, the Chinese Foreign Minister expressed theview that “the Huangyan Dao is not a sand bank but rather an island,”507 in apparent correctionof a view expressed earlier by the Philippine Undersecretary of Foreign Affairs that
Scarborough Shoal was a shoal, “not an island susceptible of sovereign territorial claim.” 508
Again, this statement only reveals China’s position with respect to the classification of thefeature as a high-tide feature for purposes of Article 121(1) as distinct from a low-tide elevationor submerged shoal. It does not address whether the feature falls into the “rocks” exception of
Article 121(3).
465. China has, however, taken certain actions that suggest to the Tribunal that China considers
Scarborough Shoal to be a fully entitled island. As discussed above in connection with China’s
claim to historic rights (see paragraphs 209 to 211), in 2012 China banned some fishing in the506

South China Sea north of 12° north latitude. China has also objected to the Philippines’ grant of
petroleum concessions in the West Calamian Block (SC-58) adjacent to the coast of Palawan,much of which lies beyond 200 nautical miles from any high-tide feature claimed by China,
except for Scarborough Shoal. China did not elaborate the basis for these actions, which may
have been based either on a theory of historic rights or on a claim to an exclusive economic
zone from Scarborough Shoal.
(c)China’s Position on the Status of Itu Aba

466. According to China, Itu Aba is a fully entitled island, entitled to an exclusive economic zone
and continental shelf. On 3 June 2016, China’s Foreign Ministry Spokesperson stated asfollows:
Over the history, Chinese fishermen have resided on Taiping Dao for years, working andliving there, carrying out fishing activities, digging wells for fresh water, cultivating land
and farming, building huts and temples, and raising livestock. The above activities are all
manifestly recorded in Geng Lu Bu (Manual of Sea Routes) which was passed down fromgeneration to generation among Chinese fishermen, as well as in many western navigation
logs before the 1930s.
The working and living practice of Chinese people on Taiping Dao fully proves that
Taiping Dao is an “island” which is completely capable of sustaining human habitation or
economic life of its own. The Philippines’ attempt to characterize Taiping Dao as a “rock”
exposed that its purpose of initiating the arbitration is to deny China’s sovereignty over theNansha Islands and relevant maritime rights and interests. 509

467. This express position was previously also suggested by China’s comments on the Taiwan
Authority’s statements “stressing that Taiping Dao [Itu Aba] meets the definition of island
according to UNCLOS and is therefore eligible for possessing exclusive economic zone,
continental shelf and other maritime rights and interests.” When asked to comment, China’s
Foreign Ministry Spokesperson responded with the following remarks:
The Nansha Islands including Taiping Dao have been China’s territory since ancient times.
Chinese people have long been living and working there continuously. China takes the
Nansha Islands as a whole when claiming maritime rights and interests, and Chinese people
across the Strait all have the responsibility to safeguard the property handed down from ourancestors. China is firmly against attempts of the Philippines to unilaterally deny China’s
territorial sovereignty and maritime rights and interests in the South China Sea througharbitration. 510

Award of 12 July 2016468. In this statement, China did not contradict the characterisation by the Taiwan Authority of Itu
Aba as a fully entitled island, but rather asserted that its people have lived and worked on Itu
Aba continuously, which mirrors the elements of “human habitation” and “economic life” inArticle 121(3) of the Convention.
(d)China’s Position on the Status of Other Features in the Spratly Islands

469. While China has not made statements on the Article 121 status of other specific features in the
Spratly Islands, it has made general statements that the Spratly Island group as a whole generate
full maritime entitlements. In its Position Paper, China argued that the Philippines’ selection ofparticular features was “an attempt at denying China’s sovereignty over the Nansha Islands as awhole.”511
470. In a Note Verbale to the Secretary-General of the United Nations on 14 April 2011, China
reiterated its sovereignty claims to “the islands in the South China Sea and the adjacent waters”
and stated that it “enjoys sovereign rights and jurisdiction over relevant waters as well as theseabed and subsoil thereof.” 512 China added that:
under the relevant provisions of the 1982 United Nations Convention on the Law of theSea, as well as the Law of the People’s Republic of China on the Territorial Sea and theContiguous Zone (1992) and the Law on the Exclusive Economic Zone and the Continental
Shelf of the People’s Republic of China (1998), China’s Nansha Islands is fully entitled to
Territorial Sea, Exclusive Economic Zone (EEZ) and Continental Shelf.513

471. China repeated this statement verbatim in its Position Paper. 514 However, given that the
Position Paper “does not express any position on the substantive issues related to thesubject-matter of the arbitration,”515 no further insights on China’s position on the application of
Article 121 to specific features in the Spratly Islands can be gleaned from it.
472. As far as the Tribunal is aware, China has not made specific statements about the status ofJohnson Reef, Cuarteron Reef, Fiery Cross Reef, Gaven Reef (North), or McKennan Reef forpurposes of Article 121(3) of the Convention. There are no press briefings about those features

The Tribunal’s Considerations

473. The Tribunal must interpret and apply Article 121 of the Convention in order to make decisions
with respect to the Philippines’ Submissions No. 3, 5, and 7, as well as to determine its
jurisdiction with respect to the Philippines’ Submissions No. 8 and 9.
474. Article 121 has not previously been the subject of significant consideration by courts or arbitral
tribunals 518 and has been accorded a wide range of different interpretations in scholarly
literature.519 As has been apparent in the course of these proceedings, the scope of applicationof its paragraph (3) is not clearly established. Accordingly, the Tribunal will consider theinterpretation of this provision before turning to its application to the maritime features in theSouth China Sea.
(a)Interpretation of Article 121 of the Convention

475. The critical element of Article 121 for the Tribunal is its paragraph (3), which provides that“[r]ocks which cannot sustain human habitation or economic life of their own shall have no
exclusive economic zone or continental shelf.”

The South China Sea Arbitration
Award of 12 July 2016476. In order to interpret this provision, the Tribunal must apply the provisions of the Vienna
Convention on the Law of Treaties.520 The general rule of interpretation is set out in Article 31of the Vienna Convention and provides that a treaty “shall be interpreted in good faith inaccordance with the ordinary meaning to be given to the terms of the treaty in their context andin the light of its object and purpose.”521 Further, “any subsequent practice in the application of
the treaty which establishes the agreement of the parties regarding its interpretation” shall betaken into account. Pursuant to Article 32 of the Vienna Convention, as supplementary meansof interpretation, recourse may be had to the preparatory work of the treaty to confirm its
meaning, or determine the meaning when it is otherwise ambiguous, obscure, or leads to amanifestly absurd or unreasonable result.522
477. In approaching the interpretation of Article 121, the Tribunal will separately review the text, its
context, the object and purpose of the Convention, and the travaux préparatoires, before settingout the conclusions that, in the Tribunal’s view, follow with respect to the meaning of theprovision.
i.

The Text of Article 121(3)478. Article 121(3) contains several textual elements that merit consideration, including the terms(a) “rocks”, (b) “cannot”, (c) “sustain”, (d) “human habitation”, (e) “or”, and (f) “economic lifeof their own.” Other aspects of the meaning of Article 121(3) arise from its context in theConvention and are discussed subsequently (see paragraphs 507 to 520 below).

(a)“Rocks”

479. The use in Article 121(3) of the term “rocks” raises the question of whether any geological orgeomorphological criteria were intended. In other words, was Article 121(3) intended to apply
only to features that are composed of solid rock or that are otherwise rock-like in nature?
480. In the Tribunal’s view, no such restriction necessarily follows from the use of the term in
Article 121(3). The dictionary meaning of “rock” does not confine the term so strictly, androcks may “consist of aggregates of minerals . . . and occasionally also organic matter . . . . They
vary in hardness, and include soft materials such as clays.”523 This was also the conclusion

The South China Sea Arbitration
Award of 12 July 2016reached by the International Court of Justice in Territorial and Maritime Dispute (Nicaragua v.
Colombia) when it held Colombia’s Quitasueño, a “minuscule” protrusion of coral, to be an
Article 121(3) rock:
International law defines an island by reference to whether it is ‘naturally formed’ andwhether it is above water at high tide, not by reference to its geological composition . . .
The fact that the feature is composed of coral is irrelevant. 524

481. Moreover, any contrary interpretation imposing a geological criteria on Article 121(3) would
lead to an absurd result. Within Article 121, rocks are a category of island. An island is defined
as a “naturally formed area of land,” without any geological or geomorphological qualification.
Introducing a geological qualification in paragraph (3) would mean that any high-tide features
formed by sand, mud, gravel, or coral—irrespective of their other characteristics—would
always generate extended maritime entitlements, even if they were incapable of sustaining
human habitation or an economic life of their own. Such features are more ephemeral than ageological rock and may shift location or appear and disappear above high water as a result ofconditions over time. A geological criterion would thus accord greater entitlements to lessstable and less permanent features. This cannot have been the intent of the Article.
482. The result of this interpretation is that “rocks” for the purposes of Article 121(3) will notnecessarily be composed of rock. The Tribunal takes the opportunity to note that the name of afeature will likewise have no bearing on whether it qualifies as a rock for purposes of
Article 121(3). A feature may have “Island” or “Rock” in its name and nevertheless be entirely
submerged. Conversely a feature with “Reef” or “Shoal” in its name may have protrusions thatremain exposed at high tide. In any event, the name of a feature provides no guidance as towhether it can sustain human habitation or an economic life of its own.
(b)“cannot”

483. The use of the word “cannot” in Article 121(3) indicates a concept of capacity. Does the feature
in its natural form have the capability of sustaining human habitation or an economic life? If
not, it is a rock. This enquiry is not concerned with whether the feature actually does sustain
human habitation or an economic life. It is concerned with whether, objectively, the feature is
apt, able to, or lends itself to human habitation or economic life. 525 That is, the fact that a

According to the Philippines, “the other authentic texts [of Article 121] reflect the same meaning as the
English term “cannot”: Merits Hearing Tr. (Day 2), p. 70. The Philippines notes that “[i]n Chinese,‘cannot’ is ‘bu neng’, which means ‘not able’ or ‘unable’. Also, for example, the Spanish text uses thephrase ‘no aptas’; again, ‘not able’, ‘unable.” Merits Hearing Tr. (Day 2), p. 71.

206

feature is currently not inhabited does not prove that it is uninhabitable. The fact that it has no
economic life does not prove that it cannot sustain an economic life.
484. Nevertheless, historical evidence of human habitation and economic life in the past may be
relevant for establishing a feature’s capacity. If a known feature proximate to a populated landmass was never inhabited and never sustained an economic life, this may be consistent with an
explanation that it is uninhabitable. Conversely, positive evidence that humans historically
lived on a feature or that the feature was the site of economic activity could constitute relevant
evidence of a feature’s capacity.
(c)“sustain”

485. The ordinary meaning of sustain generally means to “support, maintain, uphold.” The Oxford
English Dictionary defines it as “to keep in existence, maintain; spec. to cause to continue in acertain state for an extended period or without interruption; to keep or maintain at the properlevel, standard, or rate; to preserve the status of.”526
486. When used in respect “of land, a place, etc.,” to sustain means “to provide or be the source ofthe food, drink, etc., necessary to keep (a person) alive and healthy); (of food, drink, etc.) togive essential nourishment to (a person).”527 Stated otherwise, it means “to support or maintain(life) by providing food, drink, and other necessities.” 528 When used in connection withsustaining a person, sustain means to “maintain . . . in life and health; to provide with food,drink and other substances necessary for remaining alive; to feed, to keep.” 529 When used inconnection with sustaining an activity, “sustain” is defined to mean “To keep in existence,
maintain; spec. to cause to continue in a certain state for an extended period or without
interruption.”530
487. The Tribunal considers that the ordinary meaning of “sustain” has three components. The firstis the concept of the support and provision of essentials. The second is a temporal concept: thesupport and provision must be over a period of time and not one-off or short-lived. The third isa qualitative concept, entailing at least a minimal “proper standard”. Thus, in connection withsustaining human habitation, to “sustain” means to provide that which is necessary to keep

207

Award of 12 July 2016humans alive and healthy over a continuous period of time, according to a proper standard. In
connection with an economic life, to “sustain” means to provide that which is necessary not justto commence, but also to continue, an activity over a period of time in a way that remains viable
on an ongoing basis.
(d)“human habitation”

488. The ordinary meaning of “human habitation” is the “action of dwelling in or inhabiting as aplace of residence; occupancy by inhabitants” or “a settlement”. 531 “Inhabit” is defined asmeaning “to dwell in, occupy as an abode, to live permanently or habitually in (a region,
element, etc.); to reside in (a country, town, dwelling, etc.).”532
489. In the Tribunal’s view, the use in Article 121(3) of the term “habitation” includes a qualitative
element that is reflected particularly in the notions of settlement and residence that are inherent
in that term. The mere presence of a small number of persons on a feature does not constitutepermanent or habitual residence there and does not equate to habitation. Rather, the term
habitation implies a non-transient presence of persons who have chosen to stay and reside on thefeature in a settled manner. Human habitation would thus require all of the elements necessary
to keep people alive on the feature, but would also require conditions sufficiently conducive tohuman life and livelihood for people to inhabit, rather than merely survive on, the feature.
490. Forms of human habitation and livelihood vary greatly, and in an international instrument suchas the Convention, no particular culture or mode of habitation should be assumed for the
purpose of Article 121(3). Certain factors, however, remain constant wherever habitation byhumans is concerned. At a minimum, sustained human habitation would require that a feature
be able to support, maintain, and provide food, drink, and shelter to some humans to enable
them to reside there permanently or habitually over an extended period of time.
491. In the Tribunal’s view, the term “habitation” also generally implies the habitation of the feature
by a group or community of persons. No precise number of persons is specified in the Article,
but providing the basic necessities for a sole individual would not typically fall within theordinary understanding of human habitation: humans need company and community oversustained periods of time.
492. Beyond these basic requirements—necessary to provide for the daily subsistence and survival ofa number of people for an indefinite time—the Tribunal considers that the text of Article 121(3)531“Habitation,” Oxford English Dictionary (Annex 815).

532“Inhabit,” Shorter Oxford English Dictionary (5th ed., 2002).

208

The South China Sea Arbitration
Award of 12 July 2016

does not directly indicate the threshold that would separate settled human habitation from themere presence of humans.

Nor does the text of Article 121(3) elucidate the physicalcharacteristics of a feature that would be necessary to sustain the more settled mode of humanhabitation, rather than merely ensuring human survival.
(e)

“or”

493. Article 121(3) provides that “[r]ocks which cannot sustain human habitation or economic life of
their own shall have no exclusive economic zone or continental shelf.” The Tribunal must
consider whether the criteria of capacity to sustain “human habitation” and an “economic life of[its] own” are both required for a feature to be entitled to an exclusive economic zone andcontinental shelf, or whether one will suffice. The Philippines urges the Tribunal to adopt theformer interpretation, arguing that:As a matter of logic, the combination of a negative verb form with the disjunctive “or”
creates a cumulative requirement. It is, in essence, a double negative. It follows that to beentitled to an EEZ and continental shelf, an insular feature must be able both to sustain
human habitation and to sustain economic life of its own. 533

494. The Tribunal agrees with the Philippines regarding the importance of logic in the interpretationof this provision, but not with the conclusion advanced by the Philippines. Applied to the textof Article 121(3), formal logic would hold that “[r]ocks which cannot sustain (human habitation
or economic life of their own)” is equal to “[r]ocks which cannot sustain human habitation [andwhich cannot sustain] economic life of their own.” Formal logic would therefore require that afeature fail both criteria before it would be disentitled to an exclusive economic zone andcontinental shelf. The text creates a cumulative requirement, as the Philippines argues, but thenegative overall structure of the sentence means that the cumulative criteria describe thecircumstances in which a feature will be denied such maritime zones. The logical result
therefore is that if a feature is capable of sustaining either human habitation or an economic lifeof its own, it will qualify as a fully entitled island.
495. The Tribunal is conscious, however, that formal logic accords imperfectly with linguistic usage
at the best of times, even among legal drafters, and is hesitant to accord decisive weight tological construction alone. Here, it could well be argued that a natural reading of the phrase
would include an implied second negation, omitted only to reduce the length of an alreadysomewhat cumbersome clause: in other words, that “[r]ocks which cannot sustain humanhabitation or [which cannot sustain] economic life of their own shall have no exclusive
economic zone or continental shelf.”533

In the Tribunal’s view, however, this possibility is

Merits Hearing Tr. (Day 2), p. 84.

209

The South China Sea Arbitration
Award of 12 July 2016

foreclosed by the remainder of the paragraph. The first clause of Article 121(3) is not the only
negation of a disjunction within the provision. The same construction is repeated in the second
half of the paragraph where it provides that such rocks “shall have no exclusive economic zone
or continental shelf.” Here, however, the logical construction is unequivocally correct: thephrase can only be interpreted to mean that a rock which fails to meet the criteria of theparagraph “shall have no exclusive economic zone [and shall have no] continental shelf.” Thealternative, in which rocks falling short of the Convention’s threshold would generate anentitlement to one or the other of an exclusive economic zone or a continental shelf—but not
both—is manifestly absurd and contrary to the clear intent of the Article.
496. The formulation of the remainder of Article 121(3) thus serves to resolve any doubt regarding
the interpretation of the phrase “[r]ocks which cannot sustain human habitation or economic lifeof their own.” The Tribunal does not consider it plausible that the drafters of the Convention
would have employed a strictly logical construction for one clause within the parallel structureof a single sentence and to have departed from such construction for the other. Accordingly, theTribunal concludes that, properly interpreted, a rock would be disentitled from an exclusive
economic zone and continental shelf only if it were to lack both the capacity to sustain humanhabitation and the capacity to sustain an economic life of its own.

Or, expressed morestraightforwardly and in positive terms, an island that is able to sustain either human habitationor an economic life of its own is entitled to both an exclusive economic zone and a continental
shelf (in accordance with the provisions of the Convention applicable to other land territory).
497. The Tribunal observes, however, that economic activity is carried out by humans and thathumans will rarely inhabit areas where no economic activity or livelihood is possible. The twoconcepts are thus linked in practical terms, regardless of the grammatical construction of
Article 121(3). Nevertheless, the text remains open to the possibility that a feature may be able
to sustain human habitation but offer no resources to support an economic life, or that a feature
may sustain an economic life while lacking the conditions necessary to sustain habitation
directly on the feature itself. This may particularly be the case where multiple islands are usedin concert to sustain a traditional way of life, as described by the delegate from Micronesia
during the Third UN Conference.534 The Philippines suggests that an interpretation allowing for534

The Micronesian delegate stated that:
Small islands which have no land resources to speak of need the benefits of an economic
zone and the sea’s resources within it more desperately than any other territories. It would
not be equity to deny the sea’s resources to those who need them most.
Suggestions have also been made that uninhabited islands should not have a full economic
zone. Almost all of our high islands, and almost all of our atolls, made up of low islands,
are inhabited. But some islands are inhabited only part of the year, while others are used

210

The South China Sea Arbitration
Award of 12 July 2016

such possibilities would detract from the purpose of the exclusive economic zone regime, whichis to accord rights and responsibilities to the populations of the lands that generate the zone. A
converse risk is also apparent, however, and too strict a definition, developed in the context ofparticular islands, could well deprive other populations, making use of islands in a different
way, of the resources on which they have traditionally depended.
(f)“economic life of their own”

498. The final element of the text of Article 121(3) is the phrase “economic life of their own.” In the
Tribunal’s view, two elements of this phrase require consideration. First, the text makes use of
the particular term of “economic life”. Second, the text makes clear that the features must be
capable of sustaining not simply “economic life”, but an economic life “of their own”.
499. The ordinary meaning of “economic” is “relating to the development and regulation of thematerial resources of a community”535 and may relate to a process or system by which goods
and services are produced, sold and bought, or exchanged. The term “life” suggests that themere presence of resources will be insufficient and that some level of local human activity to
exploit, develop, and distribute those resources would be required. The Tribunal also recallsthat “economic life” must be read bearing in mind the time component of “sustain”. A one-off
transaction or short-lived venture would not constitute a sustained economic life. The phrase
presupposes ongoing economic activity.

Although the drafters chose not to import any

reference to “value”, the need for the economic activity to be sustained over a period of time
does presuppose a basic level of viability for the economic activity.
500. The “of their own” component is essential to the interpretation because it makes clear that afeature itself (or group of related features) must have the ability to support an independent
economic life, without relying predominantly on the infusion of outside resources or serving
purely as an object for extractive activities, without the involvement of a local population. 536 In
not as residences but for fishing or in some functional way other than for permanent
habitation. They are all the same as vital a part of our economy and livelihood as someislands that may have permanent dwellings on them, but may have little or no fish resources
near them. We do not believe that the criteria of inhabitation or size are practical or
equitable.

According to the Philippines: “In Chinese, ‘of its own’, the phrase used is ‘qibenshen de jingji
shenghuo’, in which the term ‘qibenshen’ means ‘it itself’, and it proceeds and modifies the phrase‘economic life’, ‘jingji shenghuo’. It is therefore clear that whatever ‘economic life’ means, it must be
particular to and localised on the feature itself.” Merits Hearing Tr. (Day 2), p. 79.

211

The South China Sea Arbitration
Award of 12 July 2016

the Tribunal’s view, for economic activity to constitute the economic life of a feature, theresources around which the economic activity revolves must be local, not imported, as must be
the benefit of such activity. Economic activity that can be carried on only through the continued
injection of external resources is not within the meaning of “an economic life of their own.”
Such activity would not be the economic life of the feature as “of its own”, but an economic life
ultimately dependent on support from the outside.

Similarly, purely extractive economic

activities, which accrue no benefit for the feature or its population, would not amount to an
economic life of the feature as “of its own”.
501. In this respect, the Tribunal must particularly consider the role of economic activity centred on
the sea areas adjacent to the feature. In other words, is economic activity derived from apossible exclusive economic zone, continental shelf, or territorial sea of a feature sufficient toendow it with economic life?
502. In the Tribunal’s view, economic activity derived from a possible exclusive economic zone orcontinental shelf must necessarily be excluded. Article 121(3) is concerned with determining
the conditions under which a feature will—or will not—be accorded an exclusive economic
zone and continental shelf. It would be circular and absurd if the mere presence of economic
activity in the area of the possible exclusive economic zone or continental shelf were sufficient
to endow a feature with those very zones.
503. A different calculus applies with respect to the territorial sea. Here, no circularity would result
as any high-tide feature, regardless of its status under Article 121(3), will suffice to generate aterritorial sea. Nevertheless, Article 121(3) does require that the economic life be linked to thefeature as its own. In the Tribunal’s view, this phrase requires a link between the economic life
and the feature itself, rather than merely its adjacent waters. Accordingly, economic activity inthe territorial sea could form part of the economic life of a feature, provided that it is somehow
linked to the feature itself, whether through a local population or otherwise. Distant fisherman
exploiting the territorial sea surrounding a small rock and making no use of the feature itself,
however, would not suffice to give the feature an economic life of its own. Nor would anenterprise devoted to extracting the mineral resources of the seabed adjacent to such a featureand making no use of the feature itself.
(g)Conclusions Drawn from the Text of Article 121(3)504. Despite the complexity apparent in Article 121(3), the Tribunal considers that a number of
propositions follow from the text itself:

212

The South China Sea Arbitration
Award of 12 July 2016(a)First, the use of the term “rock” does not require that a feature be composed of rock in thegeologic sense in order to fall within the scope of the provision.

(b)Second, the use of the term “cannot” makes clear that the provision concerns theobjective capacity of the feature to sustain human habitation or economic life. Actual
habitation or economic activity at any particular point in time is not relevant, except tothe extent that it indicates the capacity of the feature.

(c)

Third, the use of the term “sustain” indicates both time and qualitative elements.
Habitation and economic life must be able to extend over a certain duration and occur toan adequate standard.

(d)Fourth, the logical interpretation of the use of the term “or” discussed above indicates thata feature that is able to sustain either human habitation or an economic life of its own will
be entitled to an exclusive economic zone and continental shelf.

505. At the same time, the Tribunal considers that the text is not specific with respect to the thresholdseparating human habitation from the mere extended presence of humans. A qualitative aspect
is apparent, but the text offers little guidance as to where this line should be drawn. Similarly,
the text does not permit an easy distinction between economic activity and an economic life,
although the phrase “of their own” does serve to exclude certain forms of activity that are
entirely dependent on external resources, devoted to using a feature as an object for extractive
activities without the involvement of a local population, or which make use solely of the waters
adjacent to a feature.
506. Article 31 of the Vienna Convention calls for the interpretation of “the terms of the treaty intheir context and in the light of its object and purpose.” It is to those latter elements that the
Tribunal now turns.
ii.

The Context of Article 121(3) and the Object and Purpose of the Convention

507. In the Tribunal’s view, two aspects of the context of Article 121(3) require consideration. First,
rocks and fully entitled islands exist in the context of a system of classifying features that
includes fully entitled islands, rocks, low-tide elevations, and submerged features.
Article 121(3) must accordingly be interpreted in conjunction with the other paragraphs of
Article 121 and in conjunction with Article 13 concerning low-tide elevations. Second, as
Article 121(3) concerns the circumstances in which a feature will be denied entitlements to an
exclusive economic zone and continental shelf, it must be interpreted in the context of those213

The South China Sea Arbitration
Award of 12 July 2016

maritime areas and in light of the purpose behind the introduction of the exclusive economic
zone.
(a)

The Context of Islands, Rocks, and Low-Tide Elevations

508. As discussed above in connection with the status of features as above or below water(see paragraphs 305 to 306), Article 13 and Article 121 both apply to a “naturally formed areaof land.” Just as a low-tide elevation or area of seabed cannot be legally transformed into an
island through human efforts, the Tribunal considers that a rock cannot be transformed into afully entitled island through land reclamation. The status of a feature must be assessed on thebasis of its natural condition.
509. In addition to maintaining the structure apparent across Articles 13 and 121, this reading is
consistent with the object and purpose of Article 121(3). If States were allowed to convert any
rock incapable of sustaining human habitation or an economic life into a fully entitled island
simply by the introduction of technology and extraneous materials, then the purpose of
Article 121(3) as a provision of limitation would be frustrated. It could no longer be used as apractical restraint to prevent States from claiming for themselves potentially immense maritime
space. In this regard, the Tribunal agrees with the Philippines that “[a] contrary rule would
create perverse incentives for States to undertake such actions to extend their maritime zones tothe detriment of other coastal States and/or the common heritage of mankind.” 537 Were afeature’s capacity to sustain allowed to be established by technological enhancements, then“every high-tide feature, no matter . . . its natural conditions, could be converted into an island
generating a 200-mile entitlement if the State that claims it is willing to devote and regularly
supply the resources necessary to sustain a human settlement.”538
510. Accordingly, the Tribunal understands the phrase “cannot sustain” to mean “cannot, without
artificial addition, sustain.” This reading is consistent with the “naturally formed” qualificationof the definition of “island” and the words “of their own” which qualify “an economic life”.
511. As noted above with respect to low-tide elevations, many of the high-tide features in the Spratly
Islands have been subjected to substantial human modification as large installations and airstrips
have been constructed on them. Desalination facilities have been installed and tillable soil
introduced. In some cases, it is now difficult to observe directly the original status of the feature
in its natural state. In such circumstances, the Tribunal considers that the Convention requires

538

Merits Hearing Tr. (Day 2), p. 73.

214

The South China Sea Arbitration
Award of 12 July 2016that the status of a feature be ascertained on the basis of its earlier, natural condition, prior to theonset of significant human modification, taking into account the best available evidence of theprevious status of the high-tide features, before intensive modification.
(b)

The Link between Article 121(3) and the Purpose of the Exclusive
Economic Zone

512. As noted above, the Tribunal considers that a close analysis of the text of Article 121(3) shedssome light on what will—and what will not—suffice for the purposes of that provision.
Ultimately, however, the Tribunal finds that the plain text of the words “human habitation” and“an economic life of its own” offers limited guidance as to the character or scale of activity thatwould satisfy the requirements of the Article. Here, the meaning of the text of Article 121(3) isshaped by its context within the Convention and the inherent connection between this provisionand the concept of the exclusive economic zone. Under the 1958 Geneva Conventions, therights and jurisdiction of States were limited to the territorial sea and the continental shelf andnothing akin to Article 121(3) was provided for. The genesis of that Article is inextricably
linked with the expansion of coastal State jurisdiction through the exclusive economic zone.
513. As discussed already in connection with the Tribunal’s consideration of historic rights in theSouth China Sea, the purpose of the exclusive economic zone that emerges from the history of
the Convention (see paragraphs 248 to 254 above) was to extend the jurisdiction of States over
the waters adjacent to their coasts and to preserve the resources of those waters for the benefit of
the population of the coastal State.
514. These objectives are apparent in the various regional declarations made prior to the Third UN
Conference by the States that were the principal proponents of expanded coastal Statejurisdiction:(a)Within Latin America, the 1952 Santiago Declaration by Chile, Ecuador, and Peru linked
the expansion of maritime zones to the obligation of governments “to ensure for theirpeoples the necessary conditions of subsistence, and to provide them with the resources
for their economic development.”539(b)Similarly, the 1970 Montevideo and Lima declarations emphasised “that ties ofgeographic, economic and social nature bind the sea, the land and man who inhabits it,

from which there arises a legitimate priority in favor of littoral peoples to benefit from thenatural resources offered to them by their maritime environment.”540(c)

In Africa, the conclusions adopted at the African States Regional Seminar on the Law of
the Sea, held at Yaoundé from 20 to 30 June 1972, emphasised that “African States haveequally the right to establish beyond the Territorial Sea an Economic Zone over which
they will have an exclusive jurisdiction for the purpose of control regulation and national
exploitation of the living resources of the Sea and their reservation for the primary benefitof their peoples and their respective economies . . . .”541(d)Finally, in 1973, the Organization of African Unity adopted the Addis Ababa declaration,
setting out draft articles for various aspects of the law of the sea and recording its
conviction “that African countries have a right to exploit the marine resources around theAfrican continent for the economic benefit of African peoples.”542

515. These objectives are also apparent in the positions taken by coastal developing States
throughout the negotiations of the Seabed Committee and the Third UN Conference, and wereemphasised equally by certain developed States with a particular dependence on fisheries.543
Ultimately, the articles of the Convention concerning the exclusive economic zone were (aswith much of the Convention) a compromise and intended to balance the interests of the peoples
of coastal developing States with the interests of the traditional maritime States and those Stateswith long-range fishing industries that opposed the expansion of coastal State jurisdiction. The
principal impetus for expanding such jurisdiction in the first instance, however, is unequivocallylinked with the interest of coastal States in preserving marine resources for the benefit of theirpeople.

A particular emphasis on the needs of developing States is also recorded in thePreamble to the Convention, which notes that the achievement of a legal order for the oceans

through the Convention would “contribute to the realization of a just and equitable international
economic order which takes into account the interests and needs of mankind as a whole and, inparticular, the special interests and needs of developing countries, whether coastal or
land-locked.”
516. As a counterpoint to the expanded jurisdiction of the exclusive economic zone, Article 121(3)serves to prevent such expansion from going too far. It serves to disable tiny features from
unfairly and inequitably generating enormous entitlements to maritime space that would serve
not to benefit the local population, but to award a windfall to the (potentially distant) State tohave maintained a claim to such a feature. Given this context, the meaning attributed to theterms of Article 121(3) should serve to reinforce, rather than counter, the purposes that theexclusive economic zone and Article 121(3) were respectively intended to serve.
517. In the Tribunal’s view, this is best accomplished by recognising the connection between thecriteria of “human habitation” and the population of the coastal State for the benefit of whom
the resources of the exclusive economic zone were to be preserved. This is not to suggest thatthe purpose of endowing an inhabited island with an exclusive economic zone would benarrowly intended to preserve the resources of the zone for the population of that island.
Rather, it is that without human habitation (or an economic life), the link between a maritime
feature and the people of the coastal State becomes increasingly slight.
518. The same connection was recognised during the Seabed Committee and can be seen in theremarks of the representative of Peru, who noted that:
It was obvious that the 200-mile limit was the maximum limit and not the only one, since
there were regions in which it could not be applied; nor should it be applied to more or lessuninhabited islands, since its main justification lay not in the existence of a territory but inthe presence of the population which inhabited it, whose needs should be satisfied throughthe use of the resources available in its environs. 544

519. This point was reiterated during the Third UN Conference by Ambassador Koh of Singapore,
who later assumed the Presidency of the Conference, when he observed that:
The rationale for the proposal that coastal States should have the right to establish an
economic zone was essentially based upon the interests of the people and the desire to
marshal the resources of ocean space for their development. . . . However, it would beunjust, and the common heritage of mankind would be further diminished, if every island,irrespective of its characteristics, was automatically entitled to claim a uniform economic
zone. Such an approach would give inequitable benefits to coastal States with small or
uninhabited islands scattered over a wide expanse of the ocean. The economic zone of a544

barren rock would be larger than the land territory of many States and larger than theeconomic zones of many coastal States. 545

A similar view was expressed at the close of the Conference by the representative of Colombia
when he noted that “Rocks are entitled only to a territorial sea since they cannot sustain humanhabitation or economic life of their own. This is logical. It is a ‘package’ which results fromthe view that these maritime spaces have been granted to benefit the inhabitants, with an
economic concept.”546
520. In this context, the Tribunal considers that the human habitation with which the drafters of
Article 121(3) were concerned was the habitation by a portion of the population for whose
benefit the exclusive economic zone was being introduced. Taken together with notions ofsettlement and residence and the qualitative aspect inherent in the term habitation, it should beunderstood to refer to the habitation of a feature by a settled group or community for whom thefeature is a home.
iii.

The Travaux Préparatoires of Article 121(3)521. The Tribunal considers that further examination of the circumstances that led to the adoption of
Article 121 is warranted for the light it sheds on the purpose of the provision itself.
(a)

The History of Article 121(3)522. An early predecessor definition of “island” was introduced at the Imperial Conference of 1923
in order to harmonise marine policy across the British Empire. Resolution 4 of the Conference
clarified that the territorial sea would extend three miles from the coastline of “the mainland andalso that of islands. The word ‘islands’ covers all portions of territory permanently above waterin normal circumstances and capable of use or habitation.” 547 An explanatory memorandum
accompanying the Resolution stated that the phrase “capable of use” had been adopted as acompromise, but was intended to mean “capable, without artificial addition, of being usedthrough all seasons for some definite commercial or defence purpose,” and that “capable of545“Summary

habitation” should mean “capable, without artificial addition, of permanent human habitation.”
The explanatory memorandum recognised that “these criteria will in many cases admit ofargument, but nothing more definite could be arrived at” and no criteria could be selectedwithout being “open to some form of criticism.”548
523. The United Kingdom sought to introduce similar criteria for islands at the 1930 League of
Nations Hague Codification Conference, when it proposed to limit the category of features
entitled to a territorial sea to pieces of “territory surrounded by water and in normal
circumstances permanently above high water. It does not include a piece of territory notcapable of occupation and use.”549 Another group of States proposed instead that an island be
any naturally formed part of the earth’s surface above water at low tide, with no requirement ofcapability for use or occupation. The compromise suggested by the preparatory committee tothe conference (although never adopted into any formal instrument) was to “allow[] an island(i.e., an isolated island) to have its own territorial waters only if it is above water at high tide,”but to “tak[e] island where are above low-water mark into account when determining the baseline for the territorial waters of another island or the mainland, if such islands be within thosewaters.”550
524. The International Law Commission adopted a similar definition in its 1956 Articles Concerning
the Law of the Sea, which provided that “every island has its own territorial sea” and defined anisland as “an area of land surrounded by water, which in normal circumstances is permanently
above high water mark.”551 A British proposal to insert that an island be “capable of effective
occupation and control” was rejected in the course of the ILC’s discussions, due to concernsthat any feature could be transformed into an island simply by installing a radio station or
weather observation post.552
525. A modified version of the ILC’s text was included in Article 10 of the 1958 Convention on the
Territorial Sea and the Contiguous Zone, which recognised a territorial sea from any island,548

defined as “a naturally formed area of land, surrounded by water, which is above water at hightide.”553 In describing islands as “naturally formed”, the drafters clearly excluded the possibilityof States obtaining a territorial sea through the creation of artificial islands.
526. Before the 1970s, the issue of very small high-tide features generating expansive continental
shelves had not yet become urgent, given both the uncertainties surrounding the definition of thelimit of the continental shelf in the 1958 Continental Shelf Convention and the limited technicalcapacity of States to exploit the deep seabed. From 1971, however, the definition of islands andtheir maritime entitlements took on a new relevance in the context of the emerging regime of
expanded maritime entitlements. At the Seabed Committee meeting in 1971, prior to the Third
UN Conference, Ambassador Arvid Pardo of Malta expressed the following concerns about theprospect of granting such entitlements to all islands without distinction:
If a 200 mile limit of jurisdiction could be founded on the possession of uninhabited,
remote or very small islands, the effectiveness of international administration of ocean
space beyond a national jurisdiction would be gravely impaired.554

527. During the meetings of the Seabed Committee, some States preferred to retain the rule that allislands generate the same entitlements and warned of the “dangers inherent in drawing any
distinction between islands according to their size, location, population.” 555 However, many
States submitted texts distinguishing between the entitlements of different types of islands on
the basis of precisely these criteria.556

528. The most extensive negotiations over the provision that became Article 121(3) took place
during the Second Session of the Third UN Conference in Caracas in 1974. 557

The

Representative of Romania expressed the following concerns:
the question of islands had to be considered within the new parameters of the enlarged
12-mile territorial sea, the 200-mile economic zone, and the concept of the common
heritage of mankind. The régime established for islands would be a contributing factor in
determining the extent of the international area in which coastal and land-locked States had
an equal interest. The tremendous diversity among islands with regard to size,
geographical situation, and economic and social importance gave some idea of thecomplexity of the problem for which generalized solutions along the lines of those adopted
at the 1958 Geneva Conference would no longer be adequate.558

529. It was during this session of the Conference that Ambassador Koh of Singapore linked theregime of islands and the need for restrictions on the features that would generate an exclusive
economic zone with development and the common heritage of mankind (see paragraph 518
above).
530. Some States opposed the introduction of special distinctions because they believed it was a“practical impossibility” to arrive at a workable formula.559 The representative of the United
Kingdom pointed out various practical problems with distinguishing entitlements based on thesize, population, or remoteness or geographical proximity of a feature in relation to the coastal
or other States. 560

The representative of Mexico agreed it would be “difficult, if not

impossible,” to draft specific regulations to cover the “immense diversity of island situations”
and therefore suggested that the “basic norm must reflect . . . that the marine space of an island557

531. Eventually, at the Third Session of the Third UN Conference in Geneva in 1975, the matter wasreferred to an informal consultative group which, without leaving records, prepared the“Informal Single Negotiating Text” that presented the exception for “rocks which cannot sustain
human habitation or economic life of their own,” within a provision identical to what became
Article 121(3) of the Convention.562
532. The Informal Single Negotiating Text reflected a “compromise”. 563 The compromise text
received support from some States,564 but efforts persisted by others, including Japan, Greece,

to the delimitation provisions in Articles 15, 74, and 83566 or a specification about “uninhabited
islets.”567 Neither was accepted.
533. Even in the final sessions of the Third UN Conference, in 1982, proposals to delete
paragraph (3) were introduced and rejected. In defence of the compromise reached, the Danish
representative emphasised that without paragraph (3), “tiny and barren islands, looked upon in
the past as mere obstacles to navigation, would miraculously become the golden keys to vast
maritime zones. That would indeed be an unwarranted and unacceptable consequence of the
new law of the sea.”568 The representative of Colombia remarked that Article 121 reflected “aunique and delicate balance and would help to preserve the common heritage in the oceans” 569
and, in the final session, recalled the link between the package compromise and the objective ofsecuring to the people of the coastal State the benefits of the exclusive economic zone (seeparagraph 518 above). 570(b)Conclusions Drawn from the Travaux Préparatoires

534. The Tribunal accepts that the travaux préparatoires of Article 121 are an imperfect guide ininterpreting the meaning of paragraph (3) of that Article. In particular, the key compromise that
produced the ultimate formulation for that text was reached through informal consultations in
1975, for which no records were kept. Nevertheless, the Tribunal considers that a number ofgeneral conclusions can be drawn from the negotiating history.

535. First, Article 121(3) is a provision of limitation. It imposes two conditions that can disqualify
high-tide features from generating vast maritime spaces. These conditions were introduced withthe object and purpose of preventing encroachment on the international seabed reserved for thecommon heritage of mankind and of avoiding the inequitable distribution of maritime spaces
under national jurisdiction. This understanding of the object and purpose of Article 121(3) is
consistent with the views of both the Philippines and China as summarised above atparagraphs 409 to 422 and 451 to 458.
536. Second, the definitions in Article 121(3) were not discussed in isolation, but were frequently
discussed in the context of other aspects of the Convention. These included: (a) the introductionof an exclusive economic zone,571 (b) the purpose of the exclusive economic zone in securing
the benefit of maritime resources for the population of the coastal State,572 (c) the question ofislands under foreign domination or colonial dependence, 573 (d) the introduction of theinternational seabed area (the common heritage of mankind),574 (e) the protection of the interests

to other land might be useful in deciding whether a high-tide feature should be a fully entitledisland. But the negotiating history clearly demonstrates the difficulty in setting, in the abstract,

“vast” or “smaller”;580 and proposals that made distinctions based on whether the surface area ofa feature measured more or less than a particular figure, such as one square kilometre 581 or ten

were large islands which were largely or completely uninhabited and small ones with dense

travaux make clear that—although size may correlate to the availability of water, food, living
space, and resources for an economic life—size cannot be dispositive of a feature’s status as afully entitled island or rock and is not, on its own, a relevant factor.

As noted by theInternational Court of Justice in Territorial and Maritime Dispute (Nicaragua v. Colombia),“international law does not prescribe any minimum size which a feature must possess in order tobe considered an island.”585
iv.

Conclusions on the Interpretation of Article 121(3)539. Drawing on the foregoing consideration of the text, context, object and purpose, and drafting
history of Article 121(3), the Tribunal reaches the following conclusions with respect to theinterpretation of that provision.
540. First, for the reasons set out above, the use of the word “rock” does not limit the provision tofeatures composed of solid rock. The geological and geomorphological characteristics of ahigh-tide feature are not relevant to its classification pursuant to Article 121(3).
541. Second, the status of a feature is to be determined on the basis of its natural capacity, without
external additions or modifications intended to increase its capacity to sustain human habitationor an economic life of its own.
542. Third, with respect to “human habitation”, the critical factor is the non-transient character of the
inhabitation, such that the inhabitants can fairly be said to constitute the natural population of
the feature, for whose benefit the resources of the exclusive economic zone were seen to merit
protection. The term “human habitation” should be understood to involve the inhabitation of
the feature by a stable community of people for whom the feature constitutes a home and on
which they can remain. Such a community need not necessarily be large, and in remote atolls a
few individuals or family groups could well suffice. Periodic or habitual residence on a feature
by a nomadic people could also constitute habitation, and the records of the Third UN

Conference record a great deal of sensitivity to the livelihoods of the populations of small island
nations.

An indigenous population would obviously suffice, but also non-indigenous

inhabitation could meet this criterion if the intent of the population was truly to reside in andmake their lives on the islands in question.
543. Fourth, the term “economic life of their own” is linked to the requirement of human habitation,and the two will in most instances go hand in hand. Article 121(3) does not refer to a feature
having economic value, but to sustaining “economic life”. The Tribunal considers that the“economic life” in question will ordinarily be the life and livelihoods of the human population
inhabiting and making its home on a maritime feature or group of features. Additionally,
Article 121(3) makes clear that the economic life in question must pertain to the feature as“of its own”. Economic life, therefore, must be oriented around the feature itself and not
focused solely on the waters or seabed of the surrounding territorial sea. Economic activity thatis entirely dependent on external resources or devoted to using a feature as an object for
extractive activities without the involvement of a local population would also fall inherently
short with respect to this necessary link to the feature itself. Extractive economic activity toharvest the natural resources of a feature for the benefit of a population elsewhere certainly
constitutes the exploitation of resources for economic gain, but it cannot reasonably beconsidered to constitute the economic life of an island as its own.
544. Fifth, the text of Article 121(3) is disjunctive, such that the ability to sustain either humanhabitation or an economic life of its own would suffice to entitle a high-tide feature to an
exclusive economic zone and continental shelf. However, as a practical matter, the Tribunal
considers that a maritime feature will ordinarily only possess an economic life of its own if it isalso inhabited by a stable human community. One exception to that view should be noted forthe case of populations sustaining themselves through a network of related maritime features.
The Tribunal does not believe that maritime features can or should be considered in an atomised
fashion. A population that is able to inhabit an area only by making use of multiple maritime
features does not fail to inhabit the feature on the grounds that its habitation is not sustained bya single feature individually. Likewise, a population whose livelihood and economic life
extends across a constellation of maritime features is not disabled from recognising that suchfeatures possess an economic life of their own merely because not all of the features are directly
inhabited.
545. Sixth, Article 121(3) is concerned with the capacity of a maritime feature to sustain humanhabitation or an economic life of its own, not with whether the feature is presently, or has been,
inhabited or home to economic life. The capacity of a feature is necessarily an objective

228

The South China Sea Arbitration
Award of 12 July 2016

criterion. It has no relation to the question of sovereignty over the feature. For this reason, thedetermination of the objective capacity of a feature is not dependent on any prior decision onsovereignty, and the Tribunal is not prevented from assessing the status of features by the factthat it has not and will not decide the matter of sovereignty over them.
546. Seventh, the capacity of a feature to sustain human habitation or an economic life of its own
must be assessed on a case-by-case basis. The drafters of the Convention considered proposals
with any number of specific tests and rejected them in favour of the general formula set out in
Article 121(3). The Tribunal considers that the principal factors that contribute to the natural
capacity of a feature can be identified. These would include the presence of water, food, andshelter in sufficient quantities to enable a group of persons to live on the feature for anindeterminate period of time. Such factors would also include considerations that would bearon the conditions for inhabiting and developing an economic life on a feature, including theprevailing climate, the proximity of the feature to other inhabited areas and populations, and thepotential for livelihoods on and around the feature. The relative contribution and importance of
these factors to the capacity to sustain human habitation and economic life, however, will varyfrom one feature to another. While minute, barren features may be obviously uninhabitable(and large, heavily populated features obviously capable of sustaining habitation), the Tribunal
does not consider that an abstract test of the objective requirements to sustain human habitation
or economic life can or should be formulated. This is particularly the case in light of the
Tribunal’s conclusion that human habitation entails more than the mere survival of humans on afeature and that economic life entails more than the presence of resources. The absence of an
abstract test, however, has particular consequences (that will be discussed below) for the
Tribunal’s approach to evidence of conditions on, and the capacity of, the features in question.
547. Eighth, the Tribunal considers that the capacity of a feature should be assessed with due regard
to the potential for a group of small island features to collectively sustain human habitation andeconomic life. On the one hand, the requirement in Article 121(3) that the feature itself sustain
human habitation or economic life clearly excludes a dependence on external supply. A featurethat is only capable of sustaining habitation through the continued delivery of supplies fromoutside does not meet the requirements of Article 121(3). Nor does economic activity thatremains entirely dependent on external resources or that is devoted to using a feature as an
object for extractive activities, without the involvement of a local population, constitute afeature’s “own” economic life. At the same time, the Tribunal is conscious that remote island
populations often make use of a number of islands, sometimes spread over significant distances,
for sustenance and livelihoods. An interpretation of Article 121(3) that sought to evaluate eachfeature individually would be in keeping neither with the realities of life on remote islands nor
229

The South China Sea Arbitration
Award of 12 July 2016

with the sensitivity to the lifestyles of small island peoples that was apparent at the Third UN
Conference. Accordingly, provided that such islands collectively form part of a network thatsustains human habitation in keeping with the traditional lifestyle of the peoples in question, theTribunal would not equate the role of multiple islands in this manner with external supply. Nor
would the local use of nearby resources as part of the livelihood of the community equate to thearrival of distant economic interests aimed at extracting natural resources.
548. Ninth, in light of the Tribunal’s conclusions on the interpretation of Article 121(3), evidence ofthe objective, physical conditions on a particular feature can only take the Tribunal so far in its
task. In the Tribunal’s view, evidence of physical conditions will ordinarily suffice only toclassify features that clearly fall within one category or the other. If a feature is entirely barrenof vegetation and lacks drinkable water and the foodstuffs necessary even for basic survival, it
will be apparent that it also lacks the capacity to sustain human habitation. The opposite
conclusion could likewise be reached where the physical characteristics of a large feature makeit definitively habitable. The Tribunal considers, however, that evidence of physical conditions
is insufficient for features that fall close to the line. It will be difficult, if not impossible, todetermine from the physical characteristics of a feature alone where the capacity merely to keeppeople alive ends and the capacity to sustain settled habitation by a human community begins.
This will particularly be the case as the relevant threshold may differ from one feature toanother.
549. In such circumstances, the Tribunal considers that the most reliable evidence of the capacity of afeature will usually be the historical use to which it has been put. Humans have shown noshortage of ingenuity in establishing communities in the far reaches of the world, often in
extremely difficult conditions.

If the historical record of a feature indicates that nothing

resembling a stable community has ever developed there, the most reasonable conclusion would
be that the natural conditions are simply too difficult for such a community to form and that thefeature is not capable of sustaining such habitation. In such circumstances, the Tribunal should
consider whether there is evidence that human habitation has been prevented or ended by forcesthat are separate from the intrinsic capacity of the feature. War, pollution, and environmental
harm could all lead to the depopulation, for a prolonged period, of a feature that, in its naturalstate, was capable of sustaining human habitation. In the absence of such intervening forces,
however, the Tribunal can reasonably conclude that a feature that has never historicallysustained a human community lacks the capacity to sustain human habitation.
550. Conversely, if a feature is presently inhabited or has historically been inhabited, the Tribunal
should consider whether there is evidence to indicate that habitation was only possible through

230

The South China Sea Arbitration
Award of 12 July 2016

outside support. Trade and links with the outside world do not disqualify a feature to the extent
that they go to improving the quality of life of its inhabitants. Where outside support is sosignificant that it constitutes a necessary condition for the inhabitation of a feature, however, it
is no longer the feature itself that sustains human habitation. In this respect, the Tribunal notesthat a purely official or military population, serviced from the outside, does not constituteevidence that a feature is capable of sustaining human habitation. Bearing in mind that the
purpose of Article 121(3) is to place limits on excessive and unfair claims by States, that
purpose would be undermined if a population were installed on a feature that, as such, would
not be capable of sustaining human habitation, precisely to stake a claim to the territory and themaritime zones generated by it. The Tribunal notes that, as a result, evidence of humanhabitation that predates the creation of exclusive economic zones may be more significant thancontemporary evidence, if the latter is clouded by an apparent attempt to assert a maritime
claim.
551. The same mode of analysis would apply equally to the past or current existence of economic
life. The Tribunal would first consider evidence of the use to which the feature has historically
been put before considering whether there is evidence to suggest that that historical record does
not fully reflect the economic life the feature could have sustained in its natural condition.
v.

The Relevance of State Practice in the Implementation of Article 121(3)552. Finally, the Tribunal recalls that Article 31(3) of the Vienna Convention provides that “anysubsequent practice in the application of the treaty which establishes the agreement of theparties regarding its interpretation” shall be taken into account together with the context. Thismeans that the Parties must have acquiesced in such practice so that one can speak of anagreement reached concerning the interpretation of the provision in question. Scrutinising thejurisprudence of the International Court of Justice on this issue, in particular the Advisory
Opinion Concerning the Legality of the Use by a State of Nuclear Weapons in Armed Conflict586
and the judgment in Kasikili/Sedudu Island,587 indicates that the threshold the Court establishes
for accepting an agreement on the interpretation by State practice is quite high. The threshold issimilarly high in the jurisprudence of the World Trade Organisation, which requires “a586Advisory Opinion Concerning the Legality of the Use by a State of Nuclear Weapons in Armed Conflict,

553. On the basis of the foregoing, the Tribunal comes to the conclusion that as far as the case before
it is concerned, there is no evidence for an agreement based upon State practice on theinterpretation of Article 121(3) which differs from the interpretation of the Tribunal as outlinedin the previous Sections.
(b)Application of Article 121(3) to Scarborough Shoal, Johnson Reef, Cuarteron
Reef, Fiery Cross Reef, Gaven Reef (North), and McKennan Reefi.

Scarborough Shoal

554. In the Tribunal’s view, Scarborough Shoal is a “rock” for purposes of Article 121(3).
555. As discussed at paragraphs 333 to 334 above, the Tribunal finds that Scarborough Shoal
includes five to seven rocks that are exposed at high tide and is accordingly a high-tide feature.
That those protrusions are composed of coral is immaterial to their classification pursuant to
Article 121(3).
556. On any account, the protrusions above high tide at Scarborough Shoal are minuscule. This isconfirmed by photographs in the record.589 They obviously could not sustain human habitationin their naturally formed state; they have no fresh water, vegetation, or living space and are
remote from any feature possessing such features. Scarborough Shoal has traditionally beenused as a fishing ground by fishermen from different States, but the Tribunal recalls that
economic activity in the surrounding waters must have some tangible link to the high-tidefeature itself before it could begin to constitute the economic life of the feature (seeparagraph 503 above). There is no evidence that the fishermen working on the reef make useof, or have any connection to, the high-tide rocks at Scarborough Shoal. Nor is there any
evidence of economic activity beyond fishing.

There is, accordingly, no evidence that

Scarborough Shoal could independently sustain an economic life of its own.

ii.

Johnson Reef

557. In the Tribunal’s view, Johnson Reef is also a “rock” for purposes of Article 121(3).
558. As discussed at paragraphs 344 to 351 above, the Tribunal finds that Johnson Reef, in its natural
condition, had at least one rock that reaches as high as 1.2 metres above Mean Sea Level and isaccordingly a high-tide feature. Like the rocks at Scarborough Shoal, the high-tide portion ofJohnson Reef lacks drinking water, vegetation, and living space. It is a minuscule, barren
feature obviously incapable, in its natural condition, of sustaining human habitation or an
economic life of its own.
559. While China has constructed an installation and maintains an official presence on Johnson Reef,
this is only possible through construction on the portion of the reef platform that submerges athigh tide.590 China’s presence is necessarily dependent on outside supplies, and there is noevidence of any human activity on Johnson Reef prior to the beginning of China’s presence in1988. As discussed above (see paragraphs 508 to 511), the status of a feature for the purpose of
Article 121(3) is to be assessed on the basis of its natural condition, prior to humanmodification. China’s construction of an installation on Johnson Reef cannot elevate its statusfrom rock to fully entitled island.
iii.

Cuarteron Reef

560. In the Tribunal’s view, Cuarteron Reef is also a “rock” for purposes of Article 121(3).
561. As discussed at paragraphs 335 to 339 above, the Tribunal finds that Cuarteron Reef, in its
natural condition, was encumbered by rocks that remain exposed one to two metres above hightide and is accordingly a high-tide feature. The high-tide portions of Cuarteron Reef areminuscule and barren, and obviously incapable, in their natural condition, of sustaining humanhabitation or an economic life of their own.
562. While China has constructed an installation and engaged in significant reclamation work at
Cuarteron Reef, this is only possible through dredging and the elevation of the portion of thereef platform that submerges at high tide. 591 China’s presence is necessarily dependent on

outside supplies, and there is no evidence of any human activity on Cuarteron Reef prior to thebeginning of China’s presence in 1988. As with the other high-tide features that have been thesubject of construction and reclamation work, the status of a feature for the purpose of
Article 121(3) is to be assessed on the basis of its natural condition, prior to humanmodification. China’s construction on Cuarteron Reef, however extensive, cannot elevate its
status from rock to fully entitled island.
iv.

Fiery Cross Reef

563. In the Tribunal’s view, Fiery Cross Reef is also a “rock” for purposes of Article 121(3).
564. As discussed at paragraphs 340 to 343 above, the Tribunal finds that Fiery Cross Reef, in its
natural condition, had one prominent rock, which remains exposed approximately one metre
above high tide, and is accordingly a high-tide feature. According to the Chinese sailingdirections, the surface area of this rock exposed at high tide amounts to only two square metres.
The high-tide portion of Fiery Cross Reef is minuscule and barren, and obviously incapable, in
its natural condition, of sustaining human habitation or an economic life of its own.
565. While China has constructed an installation and engaged in significant land reclamation work at
Fiery Cross Reef, this is only possible through dredging and the elevation of the portion of thereef platform that submerges at high tide. 592 China’s presence is necessarily dependent on
outside supplies, and there is no evidence of any human activity on Fiery Cross Reef prior to thebeginning of China’s presence in 1988. As with the other high-tide features that have been thesubject of construction and reclamation work, the status of a feature for the purpose of
Article 121(3) is to be assessed on the basis of its natural condition, prior to humanmodification. China’s construction on Fiery Cross Reef, however extensive, cannot elevate its
status from rock to fully entitled island.
v.

Gaven Reef (North)566. In the Tribunal’s view, Gaven Reef (North) is also a “rock” for purposes of Article 121(3).

Cuarteron Reef are reproduced in Compilation of Images of Cuarteron Reef (various sources) (compiled

234

The South China Sea Arbitration
Award of 12 July 2016

567. As discussed at paragraphs 359 to 366 above, the Tribunal finds that Gaven Reef (North), in its
natural condition, had a small sand cay in its north-east corner that remains exposed at high tideand is accordingly a high-tide feature. It is a minuscule, barren feature obviously incapable, in
its natural condition, of sustaining human habitation or an economic life of its own.
568. While China has constructed an installation and engaged in significant reclamation work at
Gaven Reef (North), this is only possible through dredging and the elevation of the portion of
the reef platform that submerges at high tide. 593 China’s presence is necessarily dependent on
outside supplies, and there is no evidence of any human activity on Gaven Reef (North) prior to
the beginning of China’s presence in 1988. As with the other high-tide features that have been
the subject of construction and reclamation work, the status of a feature for the purpose of
Article 121(3) is to be assessed on the basis of its natural condition, prior to humanmodification. China’s construction on Gaven Reef (North), however extensive, cannot elevate
its status from rock to fully entitled island.
vi.

McKennan Reef

569. In the Tribunal’s view, McKennan Reef is also a “rock” for purposes of Article 121(3).
570. As discussed at paragraphs 352 to 354 above, the Tribunal finds that McKennan Reef includes afeature that remains exposed at high tide and is accordingly a high-tide feature. There is no
indication that this feature is of any significant size, and the Tribunal concludes that the heightindicated on the recent Chinese chart most likely refers to a coral boulder pushed above highwater by storm activity. Such a feature would be obviously incapable, in its natural conditions,of sustaining human habitation or an economic life of its own. There is no evidence of any
human activity on McKennan Reef, nor has any State installed a human presence there.
(c)Application of Article 121 to the Spratly Islands as a Whole

571. Before turning to the status of the more significant high-tide features in the Spratly Islands, theTribunal takes note of China’s statement that “China has, based on the Nansha Islands as awhole, territorial sea, exclusive economic zone and continental shelf.” 594 The Tribunal also

Letter from the Ambassador of the People’s Republic of China to the Netherlands to the individual
members of the Tribunal (3 June 2016), enclosing Ministry of Foreign Affairs, People’s Republic of

235

The South China Sea Arbitration
Award of 12 July 2016

recalls that in its public Position Paper of 7 December 2014, China objected that “in respect of
the Nansha Islands, the Philippines selects only a few features and requests the Arbitral Tribunal
to decide on their maritime entitlements. This is in essence an attempt at denying China’s
sovereignty over the Nansha Islands as a whole.”595
572. In the Tribunal’s view, these statements can be understood in two different ways. To the extent
that China considers that the criteria of human habitation and economic life must be assessed
while bearing in mind that a population may sustain itself through the use of a network ofclosely related maritime features, the Tribunal agrees. As already noted (see paragraph 547
above), the Tribunal is conscious that small island populations will often make use of a group of
reefs or atolls to support their livelihood and, where this is the case, does not consider that
Article 121(3) can or should be applied in a strictly atomised fashion.

Accordingly, theTribunal has not limited its consideration to the features specifically identified by thePhilippines in its Submissions, but requested the Philippines to provide detailed information on
all of the significant high-tide features in the Spratly Islands. 596 The Tribunal has taken asimilarly broad approach in its own efforts to satisfy itself that the Philippines’ claims are wellfounded in fact.
573. On the other hand, China’s statements could also be understood as an assertion that the Spratly
Islands should be enclosed within a system of archipelagic or straight baselines, surrounding thehigh-tide features of the group, and accorded an entitlement to maritime zones as a single unit.
With this, the Tribunal cannot agree. The use of archipelagic baselines (a baseline surrounding
an archipelago as a whole) is strictly controlled by the Convention, where Article 47(1) limits
their use to “archipelagic states”. 597 Archipelagic States are defined in Article 46 as States“constituted wholly by one or more archipelagos and may include other islands.” 598 The
Philippines is an archipelagic State (being constituted wholly by an archipelago), is entitled to
employ archipelagic baselines, and does so in promulgating the baselines for its territorial sea.
China, however, is constituted principally by territory on the mainland of Asia and cannot meetthe definition of an archipelagic State.

Award of 12 July 2016574. In any event, however, even the Philippines could not declare archipelagic baselines
surrounding the Spratly Islands. Article 47 of the Convention limits the use of archipelagic
baselines to circumstances where “within such baselines are included the main islands and anarea in which the ratio of the area of the water to the area of the land, including atolls, isbetween 1 to 1 and 9 to 1.”599 The ratio of water to land in the Spratly Islands would greatly
exceed 9:1 under any conceivable system of baselines.
575. The Convention also provides, in its Article 7, for States to make use of straight baselines undercertain circumstances, and the Tribunal is aware of the practice of some States in employing
straight baselines with respect to offshore archipelagos to approximate the effect of archipelagic
baselines. In the Tribunal’s view, any application of straight baselines to the Spratly Islands inthis fashion would be contrary to the Convention. Article 7 provides for the application ofstraight baselines only “[i]n localities where the coastline is deeply indented and cut into, or if
there is a fringe of islands along the coast in its immediate vicinity.” These conditions do notinclude the situation of an offshore archipelago. Although the Convention does not expressly
preclude the use of straight baselines in other circumstances, the Tribunal considers that the
grant of permission in Article 7 concerning straight baselines generally, together with theconditional permission in Articles 46 and 47 for certain States to draw archipelagic baselines,
excludes the possibility of employing straight baselines in other circumstances, in particularwith respect to offshore archipelagos not meeting the criteria for archipelagic baselines. Anyother interpretation would effectively render the conditions in Articles 7 and 47 meaningless.
576. Notwithstanding the practice of some States to the contrary, the Tribunal sees no evidence thatany deviations from this rule have amounted to the formation of a new rule of customaryinternational law that would permit a departure from the express provisions of the Convention.
(d)Application of Article 121 to Other High-Tide Features in the Spratly Islandsi.

Factual Findings concerning High-Tide Features in the Spratly Islands

577. The Tribunal has reviewed a substantial volume of evidence concerning the conditions on the
more significant of the high-tide features in the Spratly Islands. This has included evidence
presented by the Philippines, as well as evidence in other publicly available sources andmaterials obtained by the Tribunal from the archives of the United Kingdom Hydrographic
Office and France’s Bibliothèque Nationale de France and Archives Nationales d’Outre-Mer.

599

Convention, art. 47(1).

578. There is no question that all of the significant high-tide features in the Spratly Islands arepresently controlled by one or another of the littoral States, which have constructed installations
and installed personnel. This presence, however, is predominantly military or governmental innature and involves significant outside supply. Moreover, many of the high-tide features havebeen significantly modified from their natural condition. Additionally, accounts of current
conditions and human habitation on the features may reflect deliberate attempts to colour thedescription in such a way as to enhance or reduce the likelihood of the feature being considered
to generate an exclusive economic zone, depending on the interests of the State in question.
Accordingly, the Tribunal considers historical evidence of conditions on the features—prior to
the advent of the exclusive economic zone as a concept or the beginning of significant humanmodification—to represent a more reliable guide to the capacity of the features to sustain humanhabitation or economic life.
579. The Tribunal will review different aspects of conditions on the features in turn.
(a)

The Presence of Potable Fresh Water

580. There are consistent reports, throughout the record, of small wells located on a number offeatures in the Spratly Islands.

The 1868 edition of the China Sea Directory, reflecting

observations collected in the course of HMS Rifleman’s survey work in the area, notes thepresence of small wells on Itu Aba, Thitu, and North-East Cay, observing with respect to
Itu Aba that “the water found in the well on that island was better than elsewhere.” 600
HMS Rambler reported a similar small well on Namyit in 1888;601 HMS Iroquois described two
wells on South-West Cay in 1926;602 and HMS Herald reported a well on Spratly Island in
1936.603 Finally, the 1944 British Sailing Directions for the Dangerous Ground describe two
wells on Nanshan Island.604

581. Where water quality is noted, the results appear to be varied. In addition to the previously noted
observation that the water on Itu Aba was “better than elsewhere”,605 the water on Thitu wasdescribed as “brackish but drinkable” in 1937,606 the water on South-West Cay was noted to be“slightly tainted” such that it “should be used with caution” in 1926,607 and the water on Spratly
Island was deemed “slightly brackish”. 608 The wells on Nanshan Island were described as“brackish”.609
582. At the same time, a Japanese survey report of Itu Aba from 1939, apparently undertaken forcommercial purposes, describes significant quantities of fresh water in the following terms:
At that time, there were four wells, but only two of them were used. One of the two wells
is one meter in diameter, and about five meters deep. There is a large quantity of theoutwelling water, and according to the result of a survey, the water is suitable for drinking,and the people staying there also used the water for drinking.
Even if they had collected about 10 tons of water per day from the well, the situation of thewell has not changed at all. Since they never collected more water than about 10 tons perday, it is impossible to correctly explain the quantity of the water which the well may
supply. However, it is recognized that the well is able to supply considerable quantity ofwater.
Besides the well mentioned above, the other well of similar size was used for various
purposes, and all chores that require water were done using this well. The other two wells
were not used at that time and were unattended, although it is said that the water outwelledin the manner explained above in these wells. 610

583. Another Japanese account of a visit to Itu Aba in 1919 similarly indicates that “[t]he quality of
the water was good, and the quantity was abundant.”611 More recent accounts of water quality
are mixed. One study by Taiwanese botanists in 1994 indicates that “[t]he underground water issalty and unusable for drinking.”612 Another study from the same year indicates that “[o]n thewhole, the two freshwater sites actually had better water quality than in usual rivers or lakes”

and that “the freshwater resources of the island were still in good condition.”613 Media coverageof recent visits to Itu Aba by officials and guests of the Taiwan Authority of China also stressthat the well water there is drinkable.
584. In the Tribunal’s view, this record is consistent with the presence, historically, of small
freshwater lenses under most of the significant high-tide features in the Spratlys. The quality ofthis water will not necessarily match the standards of modern drinking water and may vary overtime, with rainfall, usage, and even tidal conditions affecting salinity levels. Overall, the bestsources of water appear to have been on Itu Aba and South-West Cay. The Tribunal notes theexpert evidence submitted by the Philippines on the limited capacity to be expected of the
freshwater lens at Itu Aba, but also notes that these conclusions are predicated in part on the factthat the construction of the airstrip on the feature would have reduced the soil’s capacity toabsorb rainwater and regenerate the freshwater lens.614 Ultimately, the Tribunal notes that the
freshwater resources of these features, combined presumably with rainwater collection,evidently have supported small numbers of people in the past (see paragraph 601 below) andconcludes that they are therefore able to do so in their natural condition, whether or not thatremains the case today.
(b)

Vegetation and Biology585. The record likewise indicates that the larger features in the Spratly Islands have historically
been vegetated. The 1868 edition of the British China Sea Directory describes Itu Aba as“covered with small trees and high bushes” and notes the presence of “two or three cocoa-nut
and a few plantain trees near a small well, but the most conspicuous object is a single black
clump tree.”615 Thitu is similarly described as having a “dark clump tree”, as well as “some low
bushes and two stunted cocoa-nut trees, near to which is a small well and a few plantaintrees.”616 Namyit was described in 1888 as “well covered by small trees and shrubs,”617 Loaita
was “covered with bushes”,618 and both cays on North Danger Reef were “covered with coarse

grass.”619 During the same period, however, Spratly Island is noted as having “not a bush oreven a blade of grass.”620 The crew of HMS Rifleman were also noted to have been planting
coconut trees on Spratly Island and Amboyna Cay in 1864, in order to increase visibility of thefeatures.621
586. Over time, the level of vegetation on the features appears to have increased, with Japanesecommercial interests (discussed in paragraph 610 to 611 below) having made a concerted effort
to introduce fruit trees on Itu Aba. An account from 1919 notes that “[a] huge number of
banana trees grew densely everywhere on the island. Also, wild mice ran on trees everywhereon the island, and almost all the ripe bananas had become food for the mice. In fact, the island
was dominated by mice.”622 By 1933, Itu Aba is described as having “a dense forest of papaya.
Papaya trees which were originally planted by the Japanese spilled their seeds, and thrifted
through the whole island. In addition, there remained fine palm fields, pineapple fields andsugar cane fields.”623
587. In contrast, the Division Botanique à l’Institut des Recherches Agronomiques de L’Indochinerecorded a lower level of vegetation on Namyit Island and Sand Cay. The vegetation on Namyit
Island is described as being “of poorer quality than that on Itu-Aba.”624 The Report notes thatcertain plants exist “rather abundantly” but that about 15 coconut trees “are the only trees on theisland.”625 The report further notes that Sand Cay had no trees, and describes the vegetation as“herbaceous” but “sickly”.626
588. The source of the crops recorded on Itu Aba is made clear from a 1939 account of commercial
activities during the period of Japanese presence that records as follows:
The company made an effort to develop the island for settlement, and studied the
propagation of palm trees, cultivation of papayas, pineapples and bananas, extraction of
copra, utilization of papayas, processing of pineapples, etc., and the company grew
vegetables to supply food.

Papayas grew vigorously everywhere on Long Island, and the island was also called theIsland of Papayas.627

589. Another Japanese account from 1939 records that:
As for the plants, in addition to the short trees of two or three meters, there are 131 palm
trees 7 to 10 meters tall, which bear a lot of fruit every year. In addition, there are 31 hardtrees, two meters in circumference and 15 meters tall. Further, there are 80 soft trees, one
meter in circumference and about 10 meters tall. Besides, there are many trees,
20 centimeters in circumference and about three meters tall growing densely. Besides
these, there are a number of papaya and banana trees.
Considerable portion of the open land mentioned above has started to be used as an
agriculture field, and napa and radish are grown there.
As for animals, many chickens and pigs are farmed . . . .628

590. The Japanese account is confirmed by the French, in a 1936 report by the Division Botanique àl’Institut des Recherches Agronomiques de L’Indochine, which provides the most detailed
historical account of vegetation on Itu Aba:
As expected, the vegetation of the island is very poor in species. Besides the imported
plants: one hundred coconut (well aligned on a southern part of the island and sufficiently
well developed to date already from an earlier time), castor oil and papaya trees scatteredaround the island, twenty species have been identified.
The east side and south of the island, better protected monsoon is covered with beautiful
vegetation, the more luxurious being found in soil rich in phosphates. The north and thewest, on the contrary, although having the same botanical species, are covered with tortured
vegetation, stripped of leaves, and with a lot of dead plants.
The best trees are Gordia subcordata (Boraginées) over 20 m. high having trunks up to
2 m. of diameter. They are quite numerous and scattered all over the island, especiallytowards the center.
Two Erythrina indica, also at the center of the island, reach 20 m. tall with trunks of 1 m. indiameter.
From the center and to the east is a stand of young tropical almond (Terminalia Catappa)
from 5 to 6 meters, most of which are the sprouts of ancient tropical almonds, without adoubt used by the phosphate operators. From this population, only 1 Calophyllurn
inophyllum, very vigorous, reaches 5-6 meters in height.
To the northeast, twenty Macaranga, whose species could not be determined due to lack offlowers and fruit, reach 15 to 20 meters in height. They rub shoulders with some Ochrosia
borbonica 10 meters high bearing ovoid fruits that exude a white latex.
These are the only trees present in the island. Some shrub species also grow there. One ofthem, Scaevola Kocniaii (Goode niacée), reaching 5-6 meters high, forms a belt ofvegetation all around the island, leaving nothing beyond it but the beaches of white sand.
But while these shrubs are vigorous, very green and covered with their white fruit on thesouth side – they are dead on the north side, and form no more than a hedge of branches.

At the center of the island, some Guettarda speciosa of 2 to 4 m. high live mixed withMorinda citrifolia (variety bracteata) that are very vigorous and full of fruit.
In the southwest of the island of Umlaut volutina (Urticaceae) of Gapsicum fructicosum(Solanaceae) with red fruits, Clitoria macrophylla (Papilionaceae) invaded in part by
Capparis pumila, are mixed with castor probably imported by the phosphate miners.
Everywhere, too, there are papaya, probably also introduced.
The live coverage is provided by several herbaceous species. A fern reaching over 1m.
high, Blechnum sp., forms an almost impenetrable thicket over a large part of the island.
Some sedges, Mariscus albescens, grow at the foot of the Cordia and seem to suffer fromdrought. Some Grasses: Thuaria sarmentosa and Ischoemum sp. meet here and there along
the beach. Finally, to the south and center of the island, probably where the original
vegetation has been destroyed for the extraction of phosphate, there is an endless carpet of
Ipomoea biloba covered with purple or white flowers and fruits. In the North, the groundcover consists of a creeping Tilliacée, Triumfetta radicans, which is located on the beachand in the interior of the island.
To complete this review of the vegetation, in the southwest of the islands, a few Pandanus
are loaded with large fruits.
In short, as was to be expected and apart from the introduced plants, the vegetation is very
poor since it is reduced to twenty species.
The island is now completely abandoned and the empty areas will probably reforest withsimilar species to existing ones.629

591. By 1947, following the war, Itu Aba was described in the following terms:
There are many tropical plants growing here—the land is covered in distinctly beautiful
light purple and red morning glories, which are also common on the beaches of Taiwan.
Morning glories are part of the Verbenaceae family (Lippia Nodiflora (L.) L. C. Rich), and
its Chinese name is Guojiangteng (Quwucao).
There are many Barbados nut(Nyctaginaceae family (Pisoniaalda Spanoghe), Chinese name Bishuang) and Yinye Zidan(Tournefortia ArgenfeaL, F, Boraginaceae family) (generally growing on sand by the beach(AG-12), and these plants grow very thickly. Barbados nut grows very quickly, but thetimber is not solid; the trees have diameters over ten centimeters, which can usually betoppled by one person. It cannot be used for anything other than firewood. The islands
also have coconut and banana, which taste good, but they are not numerous. Papaya andthe castor oil plant also grow very well; these two may be planted in large quantities. The
soldiers stationed on the island have cleared land to plant vegetables, which can grow, butthere is a great deal of pest damage. The Taiping Island Series [of soil] may be cultivatedto provide fruits and vegetables to stationed troops with no problem; but it would not bemeaningful to grow grains for consumption.630

592. Photos of Itu Aba from 1951 also show it as thickly wooded.631
593. The Tribunal considers the record to indicate that Itu Aba and Thitu to have been the mostheavily forested features in their natural condition, with other features covered in low bushes,
grasses, and heavy scrub. Moreover, at least Itu Aba appears to have been amenable to the629“Visite Botanique au Récif Tizard,” Bulletin économique de l’Indo-Chine, pp. 770-771 (SeptemberOctober 1936) (translation from the French original).

introduction and cultivation of papaya and banana trees, even if such species do not necessarily
appear to have been naturally occurring. The features also appear to have suffered from theimbalances common to small islands faced with introduced species, resulting in rapid shifts inthe flora and fauna.
(c)

Soil and Agricultural Potential

594. The historical record before the Tribunal contains less information concerning soil quality on
features in the Spratly Islands, and such details are generally not recorded in historical accounts.
HMS Rambler noted in 1888 that on Namyit, “[t]he soil of the island was very brown andearthy at the surface, but below a loose oolitic rock.”632 The Division Botanique à l’Institut desRecherches Agronomiques de L’Indochine who visited Itu Aba in 1936 recorded the presence ofcoral sand, natural phosphate, and guano. The Division also analysed an average sample of soil
and determined that 87 percent of it contained sand.633 Further, a Japanese description of Itu
Aba in 1939 notes that it “is covered by black soil.” 634 None of these observations isparticularly insightful with respect to the agricultural potential of the feature.
595. Recent scientific evidence is varied. A 1947 Chinese study discusses two types of soil on Itu
Aba and concludes that the more rich is “lush with morning glories; the coconut and banana
trees are doing well, but not many have been planted; the castor oil plant grows very well and isunusually prosperous.”635 The same study notes that “approximately 250 meters to the east of
the radio station and slightly to the north, in the Barbados nut shrubs, there is a small vegetable
patch of only slightly over 2 mu [1,333 square metres]; the vegetables are growing decently but
there is pest damage.” 636 Another description from 1994, apparently drawing on scientificaccounts, describes the soil on Itu Aba in the following terms:
Sand layers accumulated in the central area of the island. Layers of bird feces reach30 centimeters. The lower layers are lithified bird feces. Especially in the western area of
the island, layers of bird feces reach 1 meter. In many cases, humus soils are on theselayers, and thus people may cultivate crops.637

596. The Tribunal also takes note of the Philippines’ caution that present-day agriculture may
involve the use of imported soil,638 as well as the expert evidence provided by the Philippinesthat the capacity of the soil on Itu Aba to sustain extensive cultivation is low, as would be theoutput of such cultivation.639 Ultimately, the Tribunal considers the most instructive evidence tobe the clear indication that fruit and vegetables were being grown on Itu Aba during the periodof Japanese commercial activity (see paragraph 589 above and paragraphs 610 to 611 below).
The Tribunal sees no evidence that this would have involved the importation of soil andconcludes that it most likely reflects the capacity of the feature in its natural condition. At thesame time, the Tribunal accepts the point that the capacity for such cultivation would be limited
and that agriculture on Itu Aba would not suffice, on its own, to support a sizable population.
The Tribunal also considers that the capacity of other features in the Spratly Islands would beeven more limited and that significant cultivation would be difficult beyond the larger and more
vegetated features of Itu Aba and Thitu.
(d)Presence of Fishermen

597. The record before the Tribunal indicates the consistent presence of small numbers of fishermen,
mostly from Hainan, on the main features in the Spratly Islands. A footnote to the descriptionof Tizard Bank in the 1868 edition of the China Sea Directory reads as follows:
Hainan fisherman, who subsist by collecting trepang and tortoise-shell, were found upon
most of these islands, some of whom remain for years amongst the reefs. Junks from
Hainan annually visit the islands and reefs of the China Sea with supplies of rice and othernecessaries, for which the fishermen give trepang and other articles in exchange, and remit
their profits home; the junks leave Hainan in December or January, and return with the firstof the S.W. monsoon. The fishermen upon Itu-Aba island were more comfortably
established than the others . . . .640

598. The same volume likewise indicates that the cays on North Danger Reef “are frequented by
Chinese fishermen from Hainan, who collect beche-de-mer, turtle-shell, &c. and supply
themselves with water from a well in the centre of the north-eastern cay.”641 HMS Rambler
reported conversations with “natives (Chinese)” on Namyit in 1888, and in 1926 on North
Danger Reef HMS Iroquois described “four native fishermen, apparently from Hainan, . . .
residing on the islets, living in a hut on N.E. Cay and visiting S.W. Cay periodically for water.
Their occupation was fishing for beche-de-mer on the reefs. A junk from Hainan spent a week

fishing for beche-de-mer on North Reef during this period.” 642 The 1951 China Sea Pilot
likewise reports that “Thi tu island was inhabited by 5 Chinese in 1933.”643
599. A report of the French arrival on Itu Aba in 1933 recorded “Chinese from Hainan managed tosurvive on the cays (small rocky islands surrounded by coralliferous reefs) from turtle and sea
cucumber fishing, as well as a small area planted with coconut and banana trees andpotatoes.” 644 A later visit in 1936 by the Division Botanique à l’Institut des Recherches
Agronomiques de L’Indochine recorded that “[t]he only persons on the island seem to be atpresent, the Chinese and Japanese fishermen that the ocean-going junks drop off and pick in thecourse of their seasonal journeys from China–Singapore and from Japan–Singapore andback.”645 Finally, a French Government report from 1939, describing the Spratly Islands, notedthat “[t]here is no doubt that since time immemorial, these islands were frequented and eventemporarily inhabited by the Chinese, Malay, and Annamite fishermen that haunt these parts.”646600. In 1951, HMS Dampier reported on a visit to Itu Aba and described meeting a significant
number of Filipinos, as well as individuals who appeared to be from Hainan, although their
purpose for being at Itu Aba is reported as being unclear and no fishing gear was observed.647
601. Taken as a whole, the Tribunal concludes that the Spratly Islands were historically used bysmall groups of fishermen. Based on the clear reference from 1868, the Tribunal also accepts
that some of these individuals were present in the Spratlys for comparatively long periods oftime, with an established network of trade and intermittent supply. At the same time, the overall
number of individuals engaged in this livelihood appears to have been significantly constrained.

1918 to 1923 and although excavations were planned at [Itu Aba] and [Northeast andSouth-West Cay] operations were suspended in 1929 owing to the business falling off andall personnel were withdrawn. Thereafter in 1937 the Kaiyo Kogyo Kabushiki Kaisha(Ocean Exploration Industrial Co. Ltd.) commenced an investigation of the industrial
resources of these islands and at the same time conferred a public benefit generally byweather reports communicating with fishing vessels, replenishing supplies, assisting in
shipwrecks, &c. Most recently the Nanyo Kohatsu Kabushiki Kaisha (Southern OceanEnterprise Co. Ltd.) has commenced plans for the working of phosphates and the Hakuyo
Suisan Kabushiki Kaisha (Ocean Exploration Marine Products Co. Ltd.) for marine
produce; since then personnel of both companies reside continuously at [Itu Aba] the total
number of persons being about 130 including officials.
On the basis of this history the Imperial Government formally proclaimed possession ofthis group on 30th March, 1939. Nevertheless the French Government in July, 1933, upon
the discovery of new islands and islets in the adjacent South China Sea proclaimed
possession of the [Southern Archipelago]; at the present time near the E. end of [Itu Aba]
there are about 20 persons staying permanently who are said to belong to the FrenchIndo-China Registered Company.648

603. In the Tribunal’s view, this summary appears to correspond with other evidence in the record
concerning Japanese commercial and industrial activities on Itu Aba and South-West Cay.
HMS Iroquois’ 1926 report on South-West Cay confirms the presence of significant guano
mining:
The islet is a breeding place for sea birds, and is covered with guano, the export of which
has at some time been carried out on a considerable scale. In this connection a number of
low wooden sheds and buildings have been erected on the south side of the island, but inMay 1926 it appeared that they had been disused for some time. A trolley way runs from a
guano quarry in the centre of the island to a pier on the southern side.
Pier. A wooden pier, 330 feet long in a south-easterly direction, and with a least depth of
1 foot (0.3.M) at low water at its outer end, is situated near the centre of the southeasternside of the islet. It carries the trolley way referred to in the previous paragraph, and in May
1926 was in a poor state of repair.649

604. The same infrastructure is clearly visible in the 1926 fair chart of North Danger Reef,
reproduced below as Figure 11 on page 248.
605. Although HMS Iroquois described the facility as inactive, a British account from the following
year noted that:In July, 1927, H.M.S. Caradoc visited the reef and found a small Japanese schooner lying
close to the pier; there were about 8 persons on board and at least 12 living ashore. The
Japanese said that from 3,000 to 5,000 tons of guano were exported annually, a steamer
shipping this cargo once a year.650

606. A similar mining operation was established on Itu Aba in 1921 and later described as follows:

The mining of phosphate ore started to operate in 1921 in full swing. On Long Island,
which is the base for the mining, various facilities for the mining business were eventually
prepared: for example, dormitories, warehouses, offices, a clinic, an analysis room, aweather station, etc. were built; a jetty of 84 KEN length to get goods on board wasconstructed on the sea; and tracks were made in the mining area. At that time about 200
Japanese people lived there, and it is said that the number reached about 600 by 1927.
During this period, the company mined 25,900 tons of guano, and the value of it was about
727,000 yen.651

Figure 11: Survey of South-West Cay by HMS Iroquois, 1926

607. Another account from the same year records that:
Itu Aba Island, which is called the Long Island and which has economic value. The islandis the largest island in the New Southern Archipelago, and Rasa Island Phosphate Ore Ltd.,of Ministry of Southern Ocean mined phosphate ore there from 1924 to 1926. Offices,dormitories and jetties were constructed on the land, and about 200 employees were
engaged in mining.652

608. By 1933, however, mining operations had apparently ceased. When the French briefly occupied
Itu Aba that year it was deserted, and described as follows:
The island was deserted, but two occupants had left their mark: cement wells, remains ofan iron jetty, rusted rail tracks on the embankment, and a pile of abandoned phosphates
bore witness to a Japanese enterprise dating back to 1925; then a hut made out of foliage, awell maintained potato field, a little altar with a votive tea light and stick jars to the Largods of the Chinese fishermen. A board hung on a hut, covered with characters which
could roughly be translated as “I, Ti Mung, Chief of the Junk, come here in the full moon

of March to bring you food. I found nobody, I left rice in the shelter of the rocks and I
left.”653

609. A Japanese account from the same year records the remnants of the mining operation:
Over 10,000 tons of phosphate ore were stored here which looked like a castle wall. A
Japanese-style protection bank was made on the seashore, and the frames of a big watertank were desolately abandoned: it is said that the iron plates were taken by pirates. All
buildings were destroyed, and the area bleakly became a papaya forest. Almost all of thelumber was moved to other places, and only concrete flag stones of tank wells remained; it
was done in a more thorough way than that of starving wolves devouring their prey. The
weighing machine, located at the place which used to be an analysis room, is only thing
protecting Japanese science which had spread to the south.654

610. By 1937, however, a new Japanese commercial presence had been established on Itu Aba in theform of the Kaiyo Kogyo Company, engaged in the fishing industry. This is confirmed in theaccount of HMS Herald’s visit to the area in that year, which includes the description that:
A fishing company also live on the island and engage in the turtle industry. There would
appear to be about 40 of these men, mostly Formosans by appearance, who live in large
wooden huts. The manager of the company, who only understands a few words of English,
Mr. Sadae Chiya, Kaiyokogyo Co. Ltd, Takao Formosa. He lives in an attractive little hutof two rooms.
Also on the island are a generator for electric power, and what looked like a small wirelesstransmitting and received set.”655

611. A Japanese account from 1939 confirms the same facts:
In the early Showa era, the area around the island became the major fishing places for tunas
and shellfish based on Kaohsiung City, and the Japanese were active there. They got waterin Long Island (the Itu Aba Island) and North Danger (so called the Danger Island). In
other words, at that time, the place was considerably developed as a fishery advanced baseof Kaohsiung, and thus the fishermen of Kaohsiung feel that it is strange for thegovernment to announce that the place will be incorporated into Kaohsiung after all theseyears. After that, Kaiyo Kogyo Company was established as suggested by Mr. Sueharu
Hirata, who is a resident of Kaohsiung City in 1935. The purposes of the company are
fishery and mining phosphate ore. The company is based in the Long Island having
employees there and has operated business to date. 656

612. During the war, Itu Aba was used as a base of operations by Japanese forces and bombed byaircraft of the U.S. Navy in May 1945.657 HMS Dampier’s account of a visit to the island in1951 records “the remains of what must have been a flourishing concern, before it was

demolished by shellfire and/or bombing.”658 Photographs taken during the visit also depict a
number of large concrete buildings, although whether these were of military construction or theremains of installations built by the Kaiyo Kogyo Company, or another commercial concern, is
unclear.
613. Following the war, a Chinese survey of Itu Aba noted the poor mineral content of guano
extracted from the Spratly Islands—an issue that may well partially explain the failure of theRasashima Phosphate Company’s operations in the 1920s—and identified fisheries as themostly likely potential commercial use of the islands:
The reserve of phosphoric guano is estimated to be over 70,000 tons. However, the content
of available phosphoric acid is too low and should not be directly applied. There is greater
variation in content and quality is uneven, thus it is not suitable as raw material to produce
phosphoric lime.
Moreover, sulfuric acid is expensive, which would increase
manufacturing costs to the point of being uneconomical. Furthermore, the Nansha Islands
are over 600 nautical miles from Yulin Harbor. Transportation is inconvenient anduneconomical, and the phosphoric guano in the Nansha Islands is not very valuable.
However, it is possible to transport guano back to Guangdong when ships supplying theisland return. We plan to engage in research on usage of the phosphoric guano; if it ispossible to improve its fertilizer efficacy, then it would meet the needs of lands in southern
China, which are short on phosphate fertilizers.
We believe that in the Nansha Islands, the industry with the best prospects is fishing. The
lagoon is calm and a good place to fish. The area is rich in skipjack tuna, abalone, palefish, shark, sea cucumber, sponge, and kelp. The most valuable are big tortoises and sea
turtles, as large as five to six hundred jin [300 to 360 kg]. They lay their eggs on the beachin moonlit nights in the spring and summer; this is the easiest time to catch them. Theirmeat is edible, tastes like beef, and is highly nutritious. Their eggs can be used to makehighly valuable medicines. Since the Japanese have constructed a 30-square meters of fishdrying courtyard and refrigeration facilities on the island, there are great expectations forthe fishery industry in this area.659

614. There is, however, no evidence of any commercial fishing operation having been established in
the Spratly Islands since 1945. Nor, in light of the advances in shipbuilding and fishingtechnology since that date, does the Tribunal see that a base of operations on a small, isolated
feature such as Itu Aba would be economically necessary, or even beneficial. Rather, thehistorical record indicates only a short period of activity by Thomas Cloma of the Philippinesand his associates (who may well have been the Filipinos encountered on Itu Aba in 1951 by thecrew of HMS Dampier), who sought to devise a commercial scheme for the islands.660 There isno evidence, however, that Mr. Cloma or his associates ever took up residence in the Spratlys or
succeeded in deriving the least economic benefit from them. Malaysia has also established a658

small resort and scuba diving enterprise on Swallow Reef, but this operation is only possible
due to significant land reclamation activities that have enlarged the small high-tide rocks on thereef; it does not represent the natural capacity of the feature. Otherwise, human activity on the
Spratly Islands appears to be entirely governmental in nature.
ii.

The Application of Article 121 and the Tribunal’s Conclusions on the Status
of Features

615. On the basis of the evidence in the record, it appears to the Tribunal that the principal high-tidefeatures in the Spratly islands are capable of enabling the survival of small groups of people.
There is historical evidence of potable water, although of varying quality, that could be
combined with rainwater collection and storage. There is also naturally occurring vegetation
capable of providing shelter and the possibility of at least limited agriculture to supplement the
food resources of the surrounding waters.

The record indicates that small numbers offishermen, mainly from Hainan, have historically been present on Itu Aba and the other moresignificant features and appear to have survived principally on the basis of the resources at hand(notwithstanding the references to annual deliveries of rice and other sundries).
616. The principal features of the Spratly Islands are not barren rocks or sand cays, devoid of fresh
water, that can be dismissed as uninhabitable on the basis of their physical characteristics alone.
At the same time, the features are not obviously habitable, and their capacity even to enablehuman survival appears to be distinctly limited. In these circumstances, and with features thatfall close to the line in terms of their capacity to sustain human habitation, the Tribunal
considers that the physical characteristics of the features do not definitively indicate the capacityof the features. Accordingly, the Tribunal is called upon to consider the historical evidence ofhuman habitation and economic life on the Spratly Islands and the implications of such
evidence for the natural capacity of the features.
617. In addition to the presence of fishermen noted above, Itu Aba and South-West Cay were the siteof Japanese mining and fishing activities in the 1920s and 1930s. The Spratlys were also thesite of the somewhat more adventurous activities of Thomas Cloma and his associates in the
1950s. More recently, many of the features have been transformed by substantial construction
efforts and are now the site of installations hosting significant numbers of personnel, generallyof a governmental nature. The first question for the Tribunal is whether any of this activity
constitutes “human habitation” or an “economic life of its own” for the purposes of
Article 121(3). The second is whether there is evidence to suggest that the historical record ofhuman activity on the Spratly Islands is not proof of the natural capacity of the features.

251

The South China Sea Arbitration
Award of 12 July 2016(a)Historical Human Habitation of the Features of the Spratly Islands

618. For the Tribunal, the criterion of human habitation is not met by the temporary inhabitation of
the Spratly Islands by fishermen, even for extended periods.

As discussed above atparagraph 542, the Tribunal considers human habitation to entail the non-transient inhabitationof a feature by a stable community of people for whom the feature constitutes a home and on
which they can remain. This standard is not met by the historical presence of fishermen thatappears in the record before the Tribunal.

Indeed, the very fact that the fishermen are

consistently recorded as being “from Hainan”, or elsewhere, is evidence for the Tribunal thatthey do not represent the natural population of the Spratlys. Nowhere is there any reference tothe fishermen “of Itu Aba”, “of Thitu”, or “of North Danger Reef,” nor is there any suggestionthat the fishermen were accompanied by their families. Nor do any of the descriptions ofconditions on the features suggest the creation of the shelter and facilities that the Tribunal
would expect for a population intending to reside permanently among the islands. Rather, therecord indicates a pattern of temporary residence on the features for economic purposes, withthe fishermen remitting their profits, and ultimately returning, to the mainland.
619. The same conclusion holds true with respect to Japanese commercial activities on Itu Aba andSouth-West Cay. A crew of Formosan labourers, brought to the Spratlys to mine guano or
capture sea turtles, is inherently transient in nature: their objective was to extract the economic
resources of the Spratlys for the benefit of the populations of Formosa and Japan to which theywould return. It was not to make a new life for themselves on the islands. It may of course
occur, and frequently does, that what is initially a remote outpost of an extractive industry willdevelop over time into a settled community. This did not, however, occur in the case of either
Itu Aba or South-West Cay. The temporary presence of these persons on the features for a few
short years does not suffice to establish a settled community within the meaning of “humanhabitation” in Article 121(3).
620. Finally, the Tribunal does not consider that the military or other governmental personnel
presently stationed on the features in the Spratly Islands by one or another of the littoral States
suffice to constitute “human habitation” for the purposes of Article 121(3). These groups areheavily dependent on outside supply, and it is difficult to see how their presence on any of theSouth China Sea features can fairly be said to be sustained by the feature itself, rather than by acontinuous lifeline of supply and communication from the mainland.

Military or othergovernmental personnel are deployed to the Spratly Islands in an effort to support the various
claims to sovereignty that have been advanced. There is no evidence that they choose to inhabit
there of their own volition, nor can it be expected that any would remain if the official need for252

The South China Sea Arbitration
Award of 12 July 2016

their presence were to dissipate. Even where the current human presence in the Spratly Islands
includes civilians, as is the case on at least Thitu and (very recently) Itu Aba, the Tribunal
considers that their presence there is motivated by official considerations and would not haveoccurred, but for the disputed claims to sovereignty over these features.
621. The Tribunal sees no indication that anything fairly resembling a stable human community has
ever formed on the Spratly Islands. Rather, the islands have been a temporary refuge and baseof operations for fishermen and a transient residence for labourers engaged in mining andfishing. The introduction of the exclusive economic zone was not intended to grant extensive
maritime entitlements to small features whose historical contribution to human settlement is asslight as that. Nor was the exclusive economic zone intended to encourage States to establish
artificial populations in the hope of making expansive claims, precisely what has now occurredin the South China Sea.

On the contrary, Article 121(3) was intended to prevent suchdevelopments and to forestall a provocative and counterproductive effort to manufacture
entitlements.
622. The Tribunal sees no evidence that would suggest that the historical absence of humanhabitation on the Spratly Islands is the product of intervening forces or otherwise does notreflect the limited capacity of the features themselves. Accordingly, the Tribunal concludes that
Itu Aba, Thitu, West York, Spratly Island, South-West Cay, and North-East Cay are not capableof sustaining human habitation within the meaning of Article 121(3). The Tribunal has also
considered, and reaches the same conclusion with respect to, the other, less significant high-tidefeatures in the Spratly Islands, which are even less capable of sustaining human habitation, butdoes not consider it necessary to list them individually.
(b)

Historical Economic Life of Their Own of the Features of the Spratly
Islands

623. In the Tribunal’s view, all of the economic activity in the Spratly Islands that appears in thehistorical record has been essentially extractive in nature (i.e., mining for guano, collecting
shells, and fishing), aimed to a greater or lesser degree at utilising the resources of the Spratlys
for the benefit of the populations of Hainan, Formosa, Japan, the Philippines, Viet Nam, orelsewhere. As set out above at paragraph 543, the Tribunal considers that, to constitute theeconomic life of the feature, economic activity must be oriented around the feature itself and not
be focused solely on the surrounding territorial sea or entirely dependent on external resources.
The Tribunal also considers that extractive economic activity, without the presence of a stablelocal community, necessarily falls short of constituting the economic life of the feature.

253

The South China Sea Arbitration
Award of 12 July 2016624. Applying this standard, the history of extractive economic activity does not constitute, for thefeatures of the Spratly Islands, evidence of an economic life of their own. In reaching thisconclusion, however, the Tribunal takes pains to emphasise that the effect of Article 121(3) is
not to deny States the benefit of the economic resources of small rocks and maritime features.
Such features remain susceptible to a claim of territorial sovereignty and will generate a
12-nautical-mile territorial sea, provided they remain above water at high tide. Rather, theeffect of Article 121(3) is to prevent such features—whose economic benefit, if any, to the State
which controls them is for resources alone—from generating a further entitlement to a
200-nautical-mile exclusive economic zone and continental shelf that would infringe on theentitlements generated by inhabited territory or on the area reserved for the common heritage ofmankind.
625. The Tribunal concludes that Itu Aba, Thitu, West York, Spratly Island, South-West Cay, andNorth-East Cay are not capable of sustaining an economic life of their own within the meaningof Article 121(3). The Tribunal has also considered, and reaches the same conclusion withrespect to, the other, less significant high-tide features in the Spratly Islands, which are evenless capable of sustaining economic life, but does not consider it necessary to list them
individually.
*
626. The Tribunal having concluded that none of the high-tide features in the Spratly Islands iscapable of sustaining human habitation or an economic life of their own, the effect ofArticle 121(3) is that such features shall have no exclusive economic zone or continental shelf.
(e)Decision on the Tribunal’s Jurisdiction with respect to Submission No. 5627. Having addressed the status of features in the Spratly Islands, the Tribunal can now return to thequestion of its jurisdiction with respect to the Philippines’ Submission No. 5, which requests the
Tribunal to declare that “Mischief Reef and Second Thomas Shoal are part of the exclusive
economic zone and continental shelf of the Philippines.”

The Tribunal will consider its

jurisdiction both with respect to the exception in Article 298 for disputes concerning sea
boundary delimitation and with respect to the effect of States that are not Parties to the present
proceedings.

254

The South China Sea Arbitration
Award of 12 July 2016i.

Maritime Boundary Delimitation and the Tribunal’s Jurisdiction

628. In its Award on Jurisdiction, the Tribunal deferred taking a decision on this aspect of its
jurisdiction, noting that this was contingent on a determination on the status of the maritime
features that the Tribunal was not prepared to make as a preliminary matter. In that decision,
the Tribunal noted as follows:
the Tribunal’s jurisdiction to decide on the merits of some of the Philippines’ Submissions
may depend upon the status of certain maritime features in the South China Sea.
Specifically, if (contrary to the Philippines’ position) any maritime feature in the Spratly
Islands constitutes an “island” within the meaning of Article 121 of the Convention,
generating an entitlement to an exclusive economic zone or continental shelf, it may be thecase that the Philippines and China possess overlapping entitlements to maritime zones in
the relevant areas of the South China Sea. In that case, the Tribunal may not be able toreach the merits of certain of the Philippines’ Submissions (Nos. 5, 8, and 9) without firstdelimiting the Parties’ overlapping entitlements, a step that it cannot take in light ofArticle 298 and China’s declaration.661

629. At the same time, the Tribunal emphasised that the Philippines’ Submission No. 5 does notitself call for the Tribunal to decide a dispute concerning sea boundary delimitation: “thepremise of the Philippines’ Submission is not that the Tribunal will delimit any overlapping
entitlements in order to declare that these features form part of the exclusive economic zone andcontinental shelf of the Philippines, but rather that no overlapping entitlements can exist.”662 In
other words, nothing in the Convention prevents a Tribunal from recognising the existence of an
exclusive economic zone or continental shelf, or of addressing the legal consequence of suchzones, in an area where the entitlements of the State claiming an exclusive economic zone orcontinental shelf are not overlapped by the entitlements of any other State. Doing so does not
implicate the delimitation of maritime boundaries or the exclusion from jurisdiction in Article
298(1)(a)(i). In the absence of any possible overlap, there is quite literally nothing to delimit.
630. The Tribunal went on to note, however, that:If, however, another maritime feature claimed by China within 200 nautical miles ofMischief Reef or Second Thomas Shoal were to be an “island” for the purposes of
Article 121, capable of generating an entitlement to an exclusive economic zone andcontinental shelf, the resulting overlap and the exclusion of boundary delimitation from the
Tribunal’s jurisdiction by Article 298 would prevent the Tribunal from addressing thisSubmission.663

631. The Tribunal has already held (see paragraphs 277 to 278 above) that there is no legal basis for
any Chinese historic rights, or sovereign rights and jurisdiction beyond those provided for in theConvention, in the waters of the South China Sea encompassed by the ‘nine-dash line’. The

255

The South China Sea Arbitration
Award of 12 July 2016

Tribunal sees no evidence that, prior to the Convention, China ever established a historic rightto the exclusive use of the living and non-living resources of the waters of the South China Sea,
whatever use it may historically have made of the Spratly Islands themselves. In any event, anysuch right would have been superseded by the adoption of the Convention and the legal creationof the exclusive economic zone. The ‘nine-dash line’ thus cannot provide a basis for any
entitlement by China to maritime zones in the area of Mischief Reef or Second Thomas Shoal
that would overlap the entitlement of the Philippines to an exclusive economic zone andcontinental shelf generated from baselines on the island of Palawan.
632. The Tribunal has now held (see paragraphs 378 and 381 above) that Mischief Reef and Second
Thomas Shoal are low-tide elevations and, as such, generate no entitlement to maritime zones of
their own. The Tribunal has also now held (see paragraph 626 above) that neither Itu Aba, nor
any other high-tide feature in the Spratly Islands, is a fully entitled island for the purposes of
Article 121 of the Convention. As such, pursuant to the operation of Article 121(3) of theConvention, these features are legally considered to be “rocks” and to generate no exclusive
economic zone or continental shelf. The Tribunal also notes that there is no maritime featurethat is above water at high tide in its natural condition and that is located within 12 nautical
miles of either Mischief Reef or Second Thomas Shoal.
633. From these conclusions, it follows that there exists no legal basis for any entitlement by China
to maritime zones in the area of Mischief Reef or Second Thomas Shoal. Accordingly, there isno situation of overlapping entitlements that would call for the application of Articles 15, 74, or
83 to delimit the overlap. Because no delimitation is required—or, indeed, even possible—
there is no possible basis for the application of the exception to jurisdiction in
Article 298(1)(a)(i).
ii.

Third Parties and the Tribunal’s Jurisdiction

634. In its Award on Jurisdiction, the Tribunal considered whether any third parties wereindispensable to the proceedings, recalled those cases in which an international court or tribunal
had declined to proceed due to the absence of an indispensable party, and concluded that “theabsence of other States as parties to the arbitration poses no obstacle.” 664 The Tribunal
reaffirms and incorporates that decision (see paragraph 157 and 168 above). In light, however,of Malaysia’s Communication to the Tribunal of 23 June 2016, the Tribunal considers it

664

Award on Jurisdiction, para. 188.

256

The South China Sea Arbitration
Award of 12 July 2016

beneficial to elaborate further on the significance of third parties and the basis for its jurisdiction
to reach the conclusions set out in this Award.
635. In its Communication, Malaysia recalls that it claims sovereignty over a number of features in
the South China Sea and “may also have overlapping maritime entitlements (including an
extended continental shelf) in the areas of some of the features that the Arbitral Tribunal has
been asked to classify.”665 Malaysia invokes Monetary Gold Removed from Rome in 1943, as
well as other cases where courts and tribunals have sought to constrain the effects of maritime
boundary delimitation on third parties, and argues that:
The Arbitral Tribunal must ensure that, in determining whether certain maritime features in
the South China Sea are entitled to specific maritime zones under UNCLOS 1982, it does
not express any position that might directly or indirectly affect the rights and interests of
Malaysia. The Arbitral Tribunal thus cannot purport to decide upon the maritime
entitlements pursuant to Articles 13 and 121 of UNCLOS 1982 of any features within the
EEZ and Continental Shelf of Malaysia as published in Malaysia’s Map of 1979. 666

636. The Tribunal observes that Malaysia has had observer status in the proceedings since
25 June 2015 and, accordingly, attended the Hearing on Jurisdiction and the Hearing on the
Merits and received copies of the full submissions in the case. It has, however, brought its
concerns to the Tribunal for the first time in June 2016. Nevertheless, the Tribunal has sought
the Parties’ comments on Malaysia’s Communication and, as set out below, has taken note of
Malaysia’s concerns.
637. The Tribunal notes that Malaysia is not a party to this arbitration and has not applied tointervene in these proceedings. As Malaysia’s Communication correctly notes, as a non-party“Malaysia is not bound by the outcome of the arbitral proceedings or any pronouncement onfact or law to be rendered by the Arbitral Tribunal.” 667 This follows generally from theprinciple that the legal effect of a judicial or arbitral decision is limited to the Parties and from
Article 296(2) of the Convention, which expressly provides that “[a]ny such decision shall haveno binding force except between the parties and in respect of that particular dispute.”
638. The Tribunal further notes that the none of the features specifically identified in the Philippines’
Submissions lies within the continental shelf limit claimed by Malaysia in its 1979 Map and that
Malaysia has not asserted the position that any maritime feature in the Spratly Islands
constitutes a fully entitled island for the purposes of Article 121(3) of the Convention. On the665

contrary, Malaysia’s joint submission (with Viet Nam) to the CLCS sets out official coordinates
for the outer limit of Malaysia’s 200-nautical-mile continental shelf claim, which isunequivocally drawn from basepoints adjacent to the coast of Borneo, rather than from any
feature in the Spratly Islands.
639. The Tribunal observes that—insofar as they involve features not claimed by Malaysia in its
1979 Map—none of its determinations with respect to the Philippines’ Submissions No. 4, 6,
or 7 bear on the rights or interests that Malaysia has asserted in its Communication. With
respect to the Philippines’ Submission No. 5, the Tribunal notes that Mischief Reef and Second
Thomas Shoal do lie within 200 nautical miles of features claimed by Malaysia, although
Malaysia itself has not claimed an exclusive economic zone or continental shelf in the area of
either Mischief Reef or Second Thomas Shoal.
640. The Tribunal considers, however, that Malaysia’s Communication overstates the MonetaryGold principle when it argues expansively that the Tribunal must “avoid deciding any questionthat requires it to adopt a view that, directly or indirectly, may affect Malaysia’s rights andinterests.” 668 Read correctly, Monetary Gold calls for a court or tribunal to refrain fromexercising its jurisdiction where the “legal interests [of a third State] would not only be affectedby a decision, but would form the very subject-matter of the decision.”669 The circumstances ofMonetary Gold, however, “represent the limit of the power of the Court to refuse to exercise its
jurisdiction,”670 and any more expansive reading would impermissibly constrain the practicalability of courts and tribunals to carry out their function. The Tribunal considers that, to theextent it has examined certain features claimed by China (that are also claimed by Malaysia) forthe purposes of assessing the possible entitlements of China in areas to which Malaysia makes
no claim, the legal interests of Malaysia do not form “the very subject-matter of the dispute”671
and are not implicated by the Tribunal’s conclusions.

641. In these circumstances, Malaysia’s rights and interests are protected, to the extent they are
implicated at all, by its status as a non-party to the proceedings and by Article 296(2), and do
not engage the rule in Monetary Gold.672*
642. For the foregoing reasons, the Tribunal concludes that it has jurisdiction with respect to thePhilippines’ Submission No. 5.
(f)Conclusion

643. Based on the considerations outlined above (see paragraphs 333 to 334), the Tribunal finds withrespect to the Philippines’ Submission No. 3 that Scarborough Shoal contains, within themeaning of Article 121(1) of the Convention, naturally formed areas of land, surrounded bywater, which are above water at high tide. However, under Article 121(3) of the Convention,
the high-tide features at Scarborough Shoal are rocks that cannot sustain human habitation or
economic life of their own and accordingly shall have no exclusive economic zone orcontinental shelf.
644. Based on the considerations outlined above (see paragraphs 335 to 351), the Tribunal finds withrespect to the Philippines’ Submission No. 7 that Johnson Reef, Cuarteron Reef, andFiery Cross Reef contain, within the meaning of Article 121(1) of the Convention, naturally
formed areas of land, surrounded by water, which are above water at high tide. However, forpurposes of Article 121(3) of the Convention, the high-tide features at Johnson Reef, Cuarteron
Reef, and Fiery Cross Reef are rocks that cannot sustain human habitation or economic life of
their own and accordingly shall have no exclusive economic zone or continental shelf.
645. Having found—contrary to the Philippines’ Submission No. 6—that Gaven Reef (North) and
McKennan Reef are naturally formed areas of land, surrounded by water, which are above waterat high tide (see paragraphs 354 and 366 above), the Tribunal finds that for purposes of
Article 121(3) of the Convention, the high-tide features at Gaven Reef (North) and McKennan
Reef are rocks that cannot sustain human habitation or economic life of their own andaccordingly shall have no exclusive economic zone or continental shelf.
646. Based on the considerations outlined above (see paragraphs 374 to 381), the Tribunal concludes
that Mischief Reef and Second Thomas Shoal are both low-tide elevations that generate no672

maritime zones of their own. The Tribunal also concludes that none of the high-tide features in
the Spratly Islands are capable of sustaining human habitation or an economic life of their own
within the meaning of those terms in Article 121(3) of the Convention. All of the high-tidefeatures in the Spratly Islands are therefore legally rocks for purposes of Article 121(3) and do
not generate entitlements to an exclusive economic zone or continental shelf.

There is,accordingly, no possible entitlement by China to any maritime zone in the area of either
Mischief Reef or Second Thomas Shoal and no jurisdictional obstacle to the Tribunal’s
consideration of the Philippines’ Submission No. 5.
647. With respect to the Philippines’ Submission No. 5, the Tribunal concludes that both Mischief
Reef and Second Thomas Shoal are located within 200 nautical miles of the Philippines’ coaston the island of Palawan and are located in an area that is not overlapped by the entitlements
generated by any maritime feature claimed by China. It follows, therefore, that, as between thePhilippines and China, Mischief Reef and Second Thomas Shoal form part of the exclusive
economic zone and continental shelf of the Philippines.
648. The Tribunal now turns to the consideration of the Philippines’ Submissions No. 8 through 13,
concerning Chinese activities in the South China Sea.

VII. CHINESE ACTIVITIES IN THE SOUTH CHINA SEA (SUBMISSIONS NO. 8 TO 13)
A.

ALLEGED INTERFERENCE WITH THE PHILIPPINES’ SOVEREIGN RIGHTS IN ITS EEZ ANDCONTINENTAL SHELF (SUBMISSION NO. 8)
1.

Introduction

649. In this Section, the Tribunal addresses the Parties’ dispute concerning the activities of Chinese
officials and Chinese vessels with respect to living and non-living resources in the areas of theSouth China Sea located within the Philippines’ exclusive economic zone and continental shelf.
This dispute is reflected in the Philippines’ Submission No. 8, which requests the Tribunal todeclare that:(8)2.

China has unlawfully interfered with the enjoyment and exercise of the sovereign
rights of the Philippines with respect to the living and non-living resources of its
exclusive economic zone and continental shelf;

Factual Background650. Documents adduced by the Philippines record several incidents since 2010 in which China has
acted to prevent the Philippines from exploiting the non-living and living resources in thewaters that lie within 200 nautical miles of the Philippines’ baselines. The following is an
overview of these incidents.
(a)Actions regarding Non-Living Resources

651. China has objected to or acted to prevent petroleum exploration by the Philippines in the South
China Sea, within 200 nautical miles of the Philippines’ baselines, on several occasions.
i.

Petroleum Blocks at Reed Bank and the M/V Veritas Voyager Incident

652. In June 2002, the Philippines awarded Sterling Energy Plc (“Sterling Energy”) a licence toexplore oil and gas deposits within the GSEC101 block, located at Reed Bank.673 The locationof the GSEC101 block is depicted in Map 4 on page 269 below.
653. In April 2005, Forum Energy Plc, a UK-based oil and gas exploration and production company(“Forum Energy”), acquired the concession from Sterling Energy and became its operator.674
On 15 February 2010, the Philippines converted the licence into a Service Contract (“SC72”).675

654. On 22 February 2010, China delivered to the Philippines a Note Verbale, expressing “its strong
objection and indignation” about the award of the Service Contract. China went on to state as
follows:
China has indisputable sovereignty, sovereign rights and jurisdiction over Nansha Islands
and its adjacent waters. The so-called “GSEC101” is situated in the waters of China’s
Nansha Islands. The aforementioned act of the Philippine side has seriously infringed upon
China’s sovereignty and sovereign rights and goes contrary to its commitments on theSouth China Sea issue and to the maintenance of peace and stability in the South China
Sea. It is illegal, null and void.676

655. On 13 May 2010, China reiterated its objections in a further Note Verbale.677
656. On 1 March 2011, M/V Veritas Voyager, a Singaporean flagged seismic survey vessel, wasengaged in conducting surveys for Forum Energy at Reed Bank, within the GSEC101 area,
when it was approached by two China Marine Surveillance (“CMS”) vessels (Zhongguo 71 andZhongguo 75). As recorded by the Philippine Navy, the following events were reported by M/V
Veritas Voyager:•

O/a 01 0549H March 2011, seven (7) Chinese fishing vessels and two (2) Marine
surveillance vessels entered the survey area. These vessels came closer to thesurvey and chase vessels to have a look at the ongoing survey operations thenheaded away southward. One of the Veritas Voyager crew who knows how to speak
Mandarin communicated with the marine surveillance vessels and was informed thatthey were on a routine surveillance patrol, and asked who they were and what they
were doing.

•

O/a 01 0509H March 2011, the two (2) marine surveillance vessels followed the
Veritas Voyager for an hour staying in the position at approximately two (2)Nautical Miles off its starboard beam. The two (2) vessels then increased speed andheaded off southwest. The mandarin speaking crew onboard MV Veritas Voyager
was able to communicate to the surveillance vessel on the details of their towed
spread.

•O/a 02 0942H March 2011, the two (2) (Chinese) surveillance vessels approached
MV Veritas Voyager again and informed them that they are operating in the
territorial waters of China under the UN charter. The Party Manager replied that the
Veritas Voyager was operating in the territory of the Philippines with all therequired permits. The Marine surveillance vessels then ordered the Veritas Voyager
to stop the production and leave the area. After consultation with CGGV senior
management, the Party Manager, informed the Chinese Surveillance vessels thatthey would stop production and proceed to the recovery area.

•

O/a 021018H March 2011, MV Veritas Voyager reported that they terminated theoperation as of 0936H due to the two Chinese Surveillance vessels that have been
tracking them and insisting that they should stop the survey. The Mandarin
speaking navigator onboard the Voyager explained what they were working for

Forum Energy on a permitted survey area. However, the Chinese surveillance
vessels demanded them to stop immediately and leave the area, stating that
according to UN treaty, MV Veritas Voyager is operating in waters belonging to thePeople’s Republic of China. Hence the crew of MV Veritas Voyager told them thatthey would stop the acquisition. In addition, the Chinese vessels have madeaggressive actions against the MV Veritas Voyager by steering at a direct course(Head on) and turning away at the last minute. 678

657. On 2 March 2011, the Philippines delivered to China a Note Verbale objecting to the incident in
the following terms:
At 9:36 a.m. today, 2 March 2011, two Chinese surveillance vessels “Zhongguo 71 and 75”
threatened a Philippine-authorized seismic survey vessel operating in Philippine waters
around Reed Bank, and demanded that it stop its activities and immediately leave the area.

The Philippine Government views the aggressive actions of the Chinese vessels as a serious

658. On 9 March 2011, the Chargé d’Affaires of the Chinese Embassy called on the acting Assistant
Secretary of Asia and Pacific Affairs of the Philippines. As recorded by the Philippines, theprincipal points conveyed by China in the conversation were as follows:
1. China has indisputable sovereignty over the waters of Nansha Islands where Reed
Bank is situatedSince ancient times, China has indisputable sovereignty over the Nansha islands and its
adjacent waters. The GSEC 101 (SC 72) area is situated in the adjacent waters of theNansha Islands (Spratlys).
On 2 March, Chinese maritime surveillance vessels were in the area. The vessels dissuaded
the Forum vessel from further work. This was an action that China had to take to safeguard
its sovereignty and sovereign rights as a result of the unilateral action from the Philippineside.
2. [The Philippines] unilateral action in the area is contrary to its commitment toChina. [The Philippines] has not given an official reply to Chinese representations on
the matter
China has made repeated representations with the Philippines on the GSEC 101 issue since
2002. In 2007, 2009 and February 2010, former Foreign Affairs Secretary Romulo
conveyed to China that [the Philippine]Government will not grant to Forum Energy theconversion of the GSEC 101 into a service contract. Secretary Romulo said that GSEC 101
will not be an issue in [Philippines]-China relations.

The South China Sea Arbitration
Award of 12 July 2016

However, PH went against its commitment and converted GSEC 101 into a service contract
in February 2010. China made repeated representations for the cancellation of the contract,
but [the Philippines]declined to reply officially to Chinese representations. Forum is now
pursuing activities in the area.
3. In consideration of overall bilateral relations, China has exercised restraint andsincerity on the issue
Looking at the issue from the context of maintaining the overall good relations between[the Philippines]and China, and maintaining peace and stability in the area, China has
exercised maximum self-restraint and sincerity on the issue.
Its vessels left the area in order to avoid escalating the issue. This demonstrates China’s
goodwill and sincerity in wanting to maintain good relations with [the Philippines].
4. China is willing to have cooperation with [the Philippines] following the principle of“setting aside disputes and pursuing joint development”
China expressed willingness to have cooperation in the area by following the principle of“shelving disputes and pursuing joint development” as a prerequisite for cooperation.
5. Is it [the Philippines’] intention to escalate tensions by undertaking high profile
unilateral actions?
Since February 2010, [the Philippines] has not replied officially to Chinese representations
on the matter but proceeded to undertake unilateral action by sending the seismic survey
ship to conduct activities. It even sent military and coast guard vessels to the area. China isperplexed and disappointed with Philippine actions. Does the Philippines want to escalate
the issue?
6. [The Philippines] is not handling the issue in a low profile manner. To avoid
creating bigger pressures on the options of both governments, [the Philippines] should
properly guide media reporting on the 2 March 2011 incident in a positive way
Contrary to [Philippine Department of Foreign Affairs] commitment to handle the GSEC
101 issue in a low profile manner, Wescom Commander General Sabban gavestrongly-worded statements to the media. An unidentified [Philippine Department of
Foreign Affairs] official also divulged the CDA’s meeting with Undersecretary Basilio tothe media. These reports have hugged headlines and aroused the attention of both peoples.
Such action is not conducive to the resolution of the issue in a low profile manner and has
created bigger pressures from the media on the solutions of both Governments to the
problem. It has created unnecessary impediments for both sides to find a way out of theissue. If not handled well, the issue will further escalate and may bring unpleasant results
for both sides, which is dangerous.
China requests that [the Philippines]actively guide media reporting in a positive way so thatthe issue will not be played up.
7. The [South China Sea] issue is the only outstanding issue in [Philippines]China
relations. Both countries should look at the issue from a higher and broader Vantage
point
The [South China Sea] issue is the only outstanding issue between [the Philippines] andChina. It is a difficult issue that could undermine bilateral relations. In handling the issue,

264

The South China Sea Arbitration
Award of 12 July 2016

both countries should proceed from the overall pursuit of maintaining close and cooperative
relations, and maintaining peace and stability in the area.680

659. From 22 to 24 March 2011, the Secretary-General of the Philippines’ Commission on Maritime
and Ocean Affairs Secretariat, visited Beijing for consultations with the Director-General of the
Ocean and Boundary Affairs Department of the Chinese Ministry of Foreign Affairs. As
recorded by the Philippines, the following views were expressed concerning the Reed Bank
incident:
2. On the Reed Bank/GSEC 101 Issue
China stated that it has sovereignty over the so-called “Nansha Islands.” According tothem, “Nansha” is a “comprehensive whole” that includes the Reed Bank. China isconcerned with the survey and exploration that are reportedly being undertaken by [thePhilippines] in the GSEC 101 area. China cannot and will never accept this. China has
always approached the issue from a broader perspective and adopted an attitude of restraint.
This however should not be misinterpreted by other countries as a reason to undertake
unilateral action on the area. If this happens, China will have reason to do exploration as
well on areas it deems as its own. Joint development is the best and most practical way toapproach the issue pending the resolution of the disputes. China is open to any [Philippine]
proposal on this matter.
[The Philippines] expressed the view that while its relations with China is an importantcomponent of [Philippine] foreign policy, the same should be founded on mutual respectfor each other’s sovereignty and dignity. In this context, [the Philippines] stated thefollowing points:•[The Philippines] exercises sovereignty and jurisdiction over the Kalayaan Island
Group (KIG).

•

Even while [the Philippines] exercises sovereignty and jurisdiction over the KIG,
nonetheless; the Reed Bank—where GSEC 101/SC 72 is situated—is not part of the“adjacent waters” of the Spratlys (Nansha) islands, using UNCLOS as a standard.

•

Reed bank is neither an island nor a rock nor a low tide elevation. It is completely
submerged under water and a continental shelf by definition. Indeed, it is part of thecontinental shelf of Palawan.

•[The Philippines], in the context of friendly relations with China, is open to Chinese
investment in the Reed Bank under [Philippine] laws.

•

However, with respect to the disputed features (e.g., islands, islets) in the Spratlys,[the Philippines] is open to exploring possible modalities or mechanisms for
managing disputes in the said area including ideas on joint cooperation.681

660. On 4 April 2011, the Philippines responded formally to China’s Notes Verbales of February and
May 2010, stating as follows:

680

Memorandum from the Acting Assistant Secretary for Asian and Pacific Affairs, Department of Foreign
Affairs, Republic of the Philippines, to the Secretary of Foreign Affairs (10 March 2011) (Annex 70)(emphasis removed from original).

681

Department of Foreign Affairs, Republic of the Philippines, to the Secretary of Foreign Affairs of the
Republic of the Philippines (28 March 2011) (Annex 71) (emphasis removed from original).

265

The South China Sea Arbitration
Award of 12 July 2016

FIRST, the Republic of the Philippines has sovereignty and jurisdiction over the Kalayaan
Island Group (KIG);SECOND, even while the Republic of the Philippines has sovereignty and jurisdiction over
the KIG, the Reed Bank where GSEC 101 is situated does not form part of the “adjacentwaters,” specifically the 12 M territorial waters of any relevant geological feature in the
KIG either under customary international law or the United Nations Convention on the Lawof the Sea (UNCLOS);THIRD, Reed Bank is not an island, a rock, or a low tide elevation. Rather, Reed Bank is acompletely submerged bank that is part of the continental margin of Palawan. Accordingly,
Reed Bank, which is about 85 M from the nearest coast of Palawan and about 595 M fromthe coast of Hainan, forms part of the 200 M continental shelf of the Philippine archipelago
under UNCLOS;
FOURTH, Articles 56 and 77 of UNCLOS provides that the coastal or archipelagic State
exercises sovereign rights over its 200 M Exclusive Economic Zone and 200 M Continental
Shelf. As such, the Philippines exercises exclusive sovereign rights over the Reed Bank.
Therefore, the action of the Philippine Department of Energy is fully consistent withinternational law. It does not impinge on the sovereignty of the People’s Republic ofChina, or violate the ASEAN-China Declaration of Conduct on the South China Sea(DOC). . . .682

ii.

The West Calamian Petroleum Block661. On 12 January 2006, the Philippine Department of Energy issued Service Contract 58 to PNOC
Exploration Corporation (“PNOC”) in respect of the West Calamian block adjacent to
Palawan.683 The location of SC58 is depicted in Map 4 on page 269 below. PNOC was joinedby Nido Petroleum Ltd. (“Nido”) as operator of the block.684

Nido Petroleum Ltd. and Service Contract 54oChinese authorities have received reports that Australian company Nido Petroleum
Ltd. is planning to sell crude oil that it extracted from the Tindalo oil well, which iscovered by Service Contract 54a. It plans to start selling the oil this August 2010.

oMr. Bai Tian [the Deputy Chief of Mission of the Chinese Embassy] further asserted
that Service Contract 54, 14, 58, 63, and other nearby service contracts are located“deep within China’s 9-dash line.” China considers the Philippines as violating andencroaching on China’s sovereignty and sovereign rights in these areas.

oChina is requesting for detailed information on these service contracts.

oChina considers this as a very serious matter and that it reserves the right tounilaterally act on this matter to protect their interests.

oChina will send the Philippines a Note Verbale on this issue.686

664. On 6 August 2010, the First Secretary of the Chinese Embassy, Mr. Yongsheng Li, met with
Nido’s Vice-President, Mr. Leonardo M. Ote. As later memorialised by Nido:
During the meeting, Mr. Yongsheng showed Mr. Ote a copy of China’s 9-dash-line map
and informed the latter that all areas within that map are being claimed by PRC, including
those areas covered by Nido’s existing service contracts with the Philippine Government.
Mr. Ote informed Mr. Yongsheng that Nido is a service contractor which derives its
licenses and permits from the [Philippine Department of Energy]. Mr. Ote suggested that
Mr. Yongsheng discuss any claims with the [Philippine Department of Energy]. Nido has
not heard from Mr. Yongsheng since then. 687

665. In September 2011, according to Nido, COSL, a Chinese service contractor, wrote to Nido’s
Operations Manager for SC 54 “signifying its refusal to conduct any seismic activity in SC54
and SC58 due to PRC’s territorial claims in the said areas.”688

The South China Sea Arbitration
Award of 12 July 2016

667. On 6 July 2011, China delivered to the Philippines a Note Verbale, objecting to the tender in thefollowing terms:
On 30 June 2011, at the launching of Fourth Philippine Energy Contracting Round(PECR4), the Department of Energy of the Philippines offered 15 petroleum blocks to local
and international companies for exploration and development. Among the aforesaid
blocks, AREA 3 and AREA 4 are situated in the waters of which China has historic titles
including sovereign rights and jurisdiction.
China has indisputable sovereignty, sovereign rights, and jurisdiction over the islands inSouth China Sea including Nansha Islands and its adjacent waters. The action of thePhilippine Government has seriously infringed on China’s sovereignty and sovereign
rights, violated the Declaration on the Conduct of Parties in the South China Sea (DOC),
cannot but complicate the disputes and affect stability in the South China Sea.
The Chinese side urges the Philippine side to immediately withdraw the bidding offer for
AREA 3 and AREA 4, refrain from any action that infringes on China’s sovereignty andsovereign rights and violates the DOC, and honor its commitment to peace and stability inthis region.690(b)Alleged Interference with Living Resources

668. China has also acted to assert its jurisdiction over fisheries in the South China Sea and to restrictfishing by Philippine nationals in areas within 200 nautical miles of the Philippines’ baselines.
i.

China’s Prevention of Fishing by Philippine Vessels at Mischief Reef

669. Beginning in 1995, China undertook the construction of certain elevated structures on the reef
platform at Mischief Reef. According to the Philippines, “[i]n relation to Mischief Reef, China
has acted to prevent Filipino fishermen from fishing there ever since it took physical control of
the reef in 1995.”691
670. In August 1995, representatives of the Philippines and China held “Bilateral Consultations on
the South China Sea Issue,” addressing among other issues Mischief Reef. The Agreed Minutesof those consultations record the Philippine representatives’ declaration that “previous to theChinese occupation of Mischief Reef, Filipino fishermen had been freely using the Mischief
Reef as shelter.”692

ii.

China’s Extension of Jurisdiction over Fisheries in the South China Sea

671. As noted in connection with the Tribunal’s consideration of China’s claim to historic rights, on
10 May 2012, the Fishery Bureau of Nanhai District under the Chinese Ministry of Agriculture
announced a fishing moratorium in the South China Sea. The announcement provided, in
relevant part, as follows:1.

All productive activity types, except for using single-layer gill net and line-fishingequipment, shall be prohibited from 16 May 12:00 p.m. until 1 August 12:00 p.m. in
the South China Sea areas from 12° north latitude up to the “Common BoundaryLine of Fujian-Guangdong Sea Areas” (including the Gulf of Tonkin) under thejurisdiction of the People’s Republic of China.

2.

During the fishing moratorium, all fishing boats subject to the prohibition shall bemoored at harbor with their nets folded without exception. No unit may supply oil
or ice to, or purchase, distribute, freeze or store fish from the fishing boats subject tothe fishing moratorium.

3.

During the fishing moratorium, any fishing boat that holds Nansha Special Fishing
Permits and goes to conduct fishing production in the sea areas of Nansha Islands
south of 12º north latitude must strictly follow the reporting system in its entry andexit of sea ports, and any production activities in the sea area prohibited under thefishing moratorium.

4.

Those who violate the fishing moratorium regulations by carrying out fishingactivities shall have their fishing catch and any illegal gains derived therefrom
confiscated and a fine of up to 50,000 yuan shall be imposed; if the circumstances
are serious, their fishing equipment shall be confiscated and their fishing permit
shall be revoked; if the circumstances are especially serious their fishing boat may
be confiscated; if it constitutes a crime, their criminal responsibility shall be
investigated according to law.693

672. The fishing ban was also announced by Xinhua, the official press agency of China, which statedthat the ban applied “in most parts of the South China Sea as part of ongoing efforts torehabilitate the area’s marine resources . . . including Huangyan Island [Scarborough Shoal] but
excluding most of the Nansha Islands.” 694 The Xinhua announcement further reported that“[t]he fishing ban is also applicable to foreign ships. A spokesman from the fishery bureau
under the [Ministry of Agriculture] said earlier this week that fishing activity conducted byforeign ships in banned areas will be seen as a ‘blatant encroachment on China’s fisheryresources.’”695

673. On 14 May 2012, the Philippines issued the following statement: “Our position is we do notrecognize China’s fishing ban in as much as portions of the ban encompass our Exclusive
Economic Zone (EEZ).”696
674. On 27 November 2012, the Standing Committee of Hainan Provincial People’s Congress
revised “The Hainan Provincial Regulation on the Control of Coastal Border Security” (“theHainan Regulation”).697 As an administrative matter, China considers the Spratly and Paracel
Islands, as well as Scarborough Shoal to form part of Hainan Province, since 2012 as part of thecity of Sansha.698 As revised, the Hainan Regulation provides as follows:
Article 2 The Regulation is applicable to the border security control in the sea areas andcoastal areas within the jurisdiction of the Hainan Province. If any matter is otherwise
regulated by other laws or administrative regulations, such laws or administrative
regulations shall apply to the matter.
...
Article 31 When entering the sea areas within the jurisdiction of the Hainan Province, allforeign ships and the people on the foreign ships shall obey the laws and regulations of thePeople’s Republic of China, and shall not have the following actions that breach the control
of coastal border security:(1)

Illegally stop or anchor when passing the sea areas under the jurisdiction of the
Hainan Province, or take provocative acts;(2)Enter or exit the border without inspection and approval, or change the entry or exit
ports without approval;(3)

Illegally board any of the islands and reefs within the jurisdiction of the Hainan
Province;(4)

Damage marine defense facilities or production and living facilities on the islands
and reefs within the jurisdiction of the Hainan Province;(5)

Engage in propaganda activities that violate national sovereignty or endanger
national security; or(6)

Conduct any other actions that breach the control of coastal border security as
specified by other laws or regulations.

...
Article 47 If a foreign ship and the people on the foreign ship have one of the following
circumstances as specified in Article 31, the authorities of the public security border canlegally take such measures as boarding the ship, conducting inspection, detention,

675. In November 2012, the Philippines delivered a Note Verbale to the Chinese Embassy in Manila,
seeking clarification of the content the Hainan Regulation:
The Philippines seeks clarification on the reported law and that foreign vessels illegallyentering the waters under the jurisdiction of Hainan Province can be boarded, inspected,
detained, confiscated, immobilized, and expelled, among other punitive actions.700

676. On 31 December 2012, an official spokesperson of China’s Foreign Ministry stated that theRegulation would only be enforced within 12 nautical miles of Hainan’s coast.701
677. In January 2013, the Philippines reiterated its request for clarification:
The Philippines seeks clarification anew on the scope of Hainan’s rules that there is nochange from regulations passed in 1999 limiting enforcement to within 12 nautical miles ofHainan’s coast, based on the recent pronouncements of Chinese Foreign Ministry
Spokesperson Hua Chunying.
The Philippines further seeks confirmation that the 12 nautical miles enforcement law isabsolutely limited to the island of Hainan only.702

678. According to the Philippines, China has never formally clarified the intended scope of
application of the Hainan Regulation.703
iii.

China’s Prevention of Fishing by Philippine vessels at Second Thomas Shoal

679. According to the Philippines, “after China took de facto control of Second Thomas Shoal in
May 2013, it began interfering with Philippine fishing activities in the area.”704
680. According to the Director of the Bureau of Fisheries and Aquatic Resources of the Philippines,
the conduct of and laws enacted by the Chinese Government “have created a deep sense of fear

among Filipino fishermen that has significantly curtailed their fishing activities and severely

3.

The Philippines’ Position(a)Jurisdiction

681. According to the Philippines, “the only limitation on the Philippines’ entitlement to an EEZ andcontinental shelf is to the extent that any nearby maritime features claimed by China might
generate overlapping entitlements.” 706 The Philippines submits that there are no maritime
features in the South China Sea claimed by China that can generate entitlements to an exclusive
economic zone in the areas relevant to its Submission No. 8.707 For the Philippines, “all of theincidents . . . fall within areas that are indisputably Philippines’ EEZ and continental shelf,”708
and no issue of maritime delimitation is implicated.
682. The Philippines likewise submits that Article 297(3) of the Convention poses no bar to its
claims because that Article (concerning jurisdiction over the living resources of the exclusive
economic zone) does not restrict compulsory dispute settlement over disputes relating to the
exclusive economic zone of the State making the claim.

According to the Philippines,“Article 297(3)(a) does not impair the Tribunal’s jurisdiction over this Submission in the first
instance because China is not ‘the coastal State’ in those areas.”709 The Philippines also argues
that Article 297(3) poses no bar to its claims regarding petroleum activities because “[b]y its
terms, the exception applies only to disputes relating to a coastal State’s sovereign rights withrespect to ‘the living resources’ in the EEZ. Non-living resources are not covered.” 710 Finally,
the Philippines submits that the Tribunal’s jurisdiction is not barred by the exception in
Article 298(1)(b) for law enforcement activities for the same reason that the exception for living
resources is not applicable: “In those areas, the Philippines—not China—enjoys the sovereign
rights that UNCLOS accords. Submission No. 8 therefore does not implicate China’s exercise

The Philippines’ Rights in the Exclusive Economic Zone

683. The Philippines submits that “the waters, seabed and subsoil of the South China Sea within
200 M of the Philippine coast, but beyond 12 M from any high-tide feature within the South
China Sea, constitute the EEZ and continental shelf of the Philippines” under Articles 57 and 76
of the Convention because none of the maritime features claimed by China “generates
entitlement to an EEZ or continental shelf.”712
684. According to the Philippines, “[b]ecause the sovereign rights and jurisdiction of the coastal
State in both the continental shelf and EEZ are exclusive, no other State may interfere with theiruse or enjoyment.” 713 The Philippines submits that “China’s interference with oil and gas
exploration and exploitation, and the measures adopted to prevent fishing in the Philippines’
EEZ and continental shelf, constitute . . . continuing violations of . . . Articles 56, 58, 61, 62, 73,
77 and 81” of the Convention.714
i.

Interference with Rights to Non-Living Resources

685. The Philippines argues that China’s assertiveness in “its claim to ‘historic rights’ over all thewaters, seabed, and subsoil within the so-called ‘nine-dash line’” has interfered with thePhilippines’ enjoyment and exercise of its sovereign rights and jurisdiction under theConvention. 715

The Philippines submits that the following actions by China constituteviolations of the Philippines’ sovereign rights and jurisdiction:(a)China’s objection to the conversion of the Philippines’ contract with Sterling Energy for
exploration of oil and gas deposits within the GSEC101 block into a service contract (seeparagraphs 652 to 655 above);716(b)

above);(d)

China’s objection to the 2011 tender for the Area 3 and 4 petroleum blocks, north-west of
Palawan (see paragraphs 666-667).

ii.

Interference with Rights to Living Resources

686. The Philippines further argues that China has interfered with the Philippines’ sovereign rights
and jurisdiction to exploit the living resources of its maritime zones by enacting and enforcing“laws and regulations that purport to extend China’s law enforcement jurisdiction, including
over fishing resources, throughout the entire area encompassed by the nine-dash line.” 717
According to the Philippines, this has created “a cloud of uncertainty which has had asubstantial chilling effect on the activities of Philippine fishermen” as well as “an environmentof insecurity . . . among all coastal States in the South China Sea.”718 The Philippines objects
specifically to:(a)

China’s prevention of fishing by Philippine vessels at Mischief Reef since 1995 (seeparagraphs 669 to 670 above);(b)

The 2012 moratorium on fishing in the South China Sea north of 12°N latitude (seeparagraphs 671 to 673 above);(c)

China’s revision of the Hainan Regulation (see paragraphs 674 to 678 above);(d)China’s prevention of fishing by Philippine vessels at Second Thomas Shoal since 1995
(see paragraphs 679 to 680 above).

4.

China’s Position

687. China has not directly stated its position with respect to the allegations presented in thePhilippines’ Submission No. 8. Nevertheless, China’s position can be discerned from its publicstatements at the time of the incidents in question.

688. With respect to the Philippines’ petroleum exploration, it is apparent that China considers that
it—and not the Philippines—has rights in the areas in question:(a)Regarding the GSEC101 contract at Reed Bank, China stated that “China has indisputable
sovereignty, sovereign rights and jurisdiction over Nansha Islands and its adjacent waters.
The so-called ‘GSEC101’ is situated in the waters of China’s Nansha Islands.”719(b)Regarding the SC58 contract, China is recorded as having stated that “Service Contract54, 14, 58, 63, and other nearby service contracts are located ‘deep within China’s 9-dashline.’ China considers the Philippines as violating and encroaching on China’s
sovereignty and sovereign rights in these areas.”720(c)And, regarding the Area 3 and Area 4 tender, China stated that “AREA 3 and AREA 4
are situated in the waters of which China has historic titles including sovereign rights andjurisdiction.”721

689. China’s statements with respect to fisheries likewise make clear that China considers that it has
sovereign rights in the areas in question. Thus, China’s Ministry of Agriculture is reported tohave stated that fishing by foreign vessels in the South China Sea north of 12° N latitude
constitutes “blatant encroachment on China’s fishery resources.”722
5.

The Tribunal’s Considerations(a)

The Tribunal’s Jurisdiction

690. In its Award on Jurisdiction, the Tribunal held that Submission No. 8 reflects a disputeconcerning “China’s actions that allegedly interfere with the Philippines’ petroleum exploration,
seismic surveys, and fishing in what the Philippines claims as its exclusive economic zone.” 723
The Tribunal noted that this is not a dispute concerning sovereignty, nor is it barred from the
Tribunal’s consideration by any requirement of Section 1 of Part XV.724

691. The Tribunal also found that the dispute at issue in Submission No. 8 does not concern thedelimitation of maritime boundaries. As with Submission No. 5, the Tribunal noted that thepremise of Submission No. 8 is “that no overlapping entitlements exist because only thePhilippines possesses an entitlement to an exclusive economic zone in the relevant areas.” 725
The Tribunal is not asked to delimit overlapping entitlements in the areas in question. Rather,its jurisdiction is contingent on the absence of any possible overlap. Had the Tribunal foundthat another maritime feature claimed by China within 200 nautical miles of the relevant areas
were a fully entitled island for purposes of Article 121 of the Convention and capable ofgenerating an entitlement to an exclusive economic zone and continental shelf, it would
necessarily have had to decline jurisdiction over the dispute.
692. The Tribunal has found, however, (see paragraphs 230 to 278 above) that there is no legal basis
for any Chinese historic rights, or other sovereign rights and jurisdiction beyond those provided
for in the Convention, in the waters of the South China Sea encompassed by the ‘nine-dash line’and that none of the high-tide feature in the Spratly Islands is a fully entitled island for the
purposes of Article 121 of the Convention (see paragraphs 473 to 626 above). There is thus no
maritime feature in the Spratly Islands that is capable of generating an entitlement to an
exclusive economic zone or continental shelf in the areas of Mischief Reef or Second Thomas
Shoal, or in the areas of the GSEC101 block, Area 3, Area 4, or the SC58 block.
693. The Tribunal has also found (see paragraphs 374 to 381 above) that Mischief Reef and Second
Thomas Shoal are low-tide elevations and, as such, generate no entitlement to maritime zones of
their own. Additionally, Reed Bank (the area of the GSEC101 block) is an entirely submerged
reef formation that cannot give rise to maritime entitlements. 726 Nor is there any high-tidefeature claimed by China within 12 nautical miles of Area 3, Area 4, or the SC58 block that
could generate an entitlement to a territorial sea in those areas.
694. From these conclusions, it follows that there exists no legal basis for any entitlement by China
to maritime zones in the area of Mischief Reef, Second Thomas Shoal, the GSEC101 block,Area 3, Area 4, or the SC58 block. There is thus no situation of overlapping entitlements thatwould call for the application of Articles 15, 74, or 83 to delimit the overlap and no possible
basis for the application of the exception to jurisdiction in Article 298(1)(a)(i).

278

The South China Sea Arbitration
Award of 12 July 2016

695. Because the areas of the South China Sea at issue for Submission No. 8 can only constitute theexclusive economic zone of the Philippines, the Tribunal also considers that Article 297(3)(a)and the law enforcement exception in Article 298(1)(b) of the Convention pose no obstacle toits jurisdiction. These provisions serve to limit compulsory dispute settlement where a claim isbrought against a State’s exercise of its sovereign rights in respect of living resources in its own
exclusive economic zone. These provisions do not apply where a State is alleged to haveviolated the Convention in respect of the exclusive economic zone of another State. The
Tribunal therefore concludes that it has jurisdiction with respect to the Philippines’
Submission No. 8.
(b)China’s Actions and the Philippines’ Sovereign Rights

696. In the Tribunal’s view, the core of the Parties’ dispute with respect to living and non-living
resources lies in their differing understandings of their respective rights in the areas of the South
China Sea within 200 nautical miles of the Philippines’ baselines that are encompassed by the‘nine-dash line’. It is apparent that the Philippines and China have each proceeded on the basisthat it, and not the other, has exclusive rights to resources and have acted accordingly.
697. As discussed above, the effect of China’s objection to compulsory dispute settlement formaritime delimitation is that the Tribunal could only address this Submission if the respective
maritime entitlements of the Parties could be established and if no overlap requiring
delimitation were found to exist. Jurisdiction has been established only because the allocationof rights under the Convention is unequivocal. Thus, the Tribunal has found that Mischief Reef,
Second Thomas Shoal, the GSEC101 block, Area 3, Area 4, or the SC58 block all fall withinareas where only the Philippines possesses possible entitlements to maritime zones under theConvention.

The relevant areas can only constitute the exclusive economic zone andcontinental shelf of the Philippines. Accordingly, the Philippines—and not China—possesses
sovereign rights with respect to resources in these areas.
698. The Convention is clear on the allocation of rights within the exclusive economic zone andcontinental shelf. With respect to non-living resources, Article 77 of the Convention provides
that the “coastal State”—which in this case is necessarily the Philippines—“exercises over thecontinental shelf sovereign rights for the purpose of exploring it and exploiting its natural
resources.” The Convention goes on to make clear that “[t]he rights referred to . . . are
exclusive in the sense that if the coastal State does not explore the continental shelf or exploit its
natural resources, no one may undertake these activities without the express consent of thecoastal State.” These provisions are unequivocal and require no further interpretation. Within

279

The South China Sea Arbitration
Award of 12 July 2016its continental shelf, only the Philippines, or another State acting with its permission, may
exploit the resources of the sea-bed.
699. The rights of other States in the waters above the continental shelf and with respect tosubmarine cables and pipelines are expressly detailed in Articles 78 and 79 of the Convention.
Nothing in these Articles permits any State to prevent another State from exercising sovereign
rights over its own continental shelf.
700. The same clarity is evident with respect to living resources and the provisions of the exclusive
economic zone. Article 56 is clear in allocating to the coastal State—which again is necessarily
the Philippines in the areas in question—“sovereign rights for the purpose of exploring andexploiting, conserving and managing the natural resources, whether living or non-living, of thewaters superjacent to the seabed and of the seabed and its subsoil, and with regard to otheractivities for the economic exploitation and exploration of the zone . . . .” The rights of otherStates in the exclusive economic zone are detailed in Article 58 and are limited to “navigationand overflight and of the laying of submarine cables and pipelines, and other internationally
lawful uses of the sea related to these freedoms.” The rights of other States do not include
restricting a coastal State from exploiting the living resources of its own exclusive economic
zone. Indeed, the very notion is incompatible with the concept of sovereign rights and theexclusive jurisdiction over fisheries that was the central objective motivating the introduction of
the exclusive economic zone concept (see paragraphs 248 to 254 above).
701. Having established the applicable law and the allocation of rights, the Tribunal now turns to theevents underpinning the Philippines’ claim.
i.

Acts in relation to Non-Living Resources702. In the case of non-living resources, the Philippines has identified three distinct types of conduct
on the part of China that it considers to violate its sovereign rights to the continental shelf:(a) diplomatic statements, in the form of China’s objections to the Philippines Government
regarding the conversion of the GSEC101 contract, the SC58 contract, and the tender for Area 3
and Area 4; (b) a statement by a Chinese official to a representative of Nido Petroleum Ltd. tothe effect that the area of Nido Petroleum’s concession from the Philippines was claimed by
China; and (c) actions by CMS vessels to order the M/V Veritas Voyager to halt operations andleave the area of Reed Bank.
703. The Tribunal notes that China’s diplomatic communications, the statements of its diplomats,and the actions of government-operated ships, such as CMS vessels, are all attributable to China
280

The South China Sea Arbitration
Award of 12 July 2016as such. These actions constitute official acts of China. At the same time, however, theTribunal reaches different conclusions with respect to the consequences of these actions.
704. As an initial matter, the Tribunal accepts that China has asserted its claim to rights in the waters
within 200 nautical miles of the Philippines baselines in good faith. That the Tribunal disagrees
with China’s understanding of its rights and considers that there is no possible legal basis for
China’s claimed rights does not mean that China’s understanding has not been genuinely held.
705. Correspondingly, the Tribunal does not consider that China’s diplomatic communications,asserting China’s understanding of its rights in the South China Sea pursuant to the Convention
and international law, can themselves constitute breaches of the provisions of the Convention
regarding the continental shelf. It is an altogether normal occurrence that States will havedifferent understandings of their respective rights. If the expression of such differences wereitself sufficient to place the State whose understanding of the law ultimately proved incorrect inbreach of the underlying obligation, it would cast an unacceptable chill on the ordinary conductof diplomacy. The Tribunal does not exclude that it could reach a different conclusion in thecase of diplomatic statements claiming rights in bad faith, or in the case of attempts by one Stateto induce another to relinquish its rights through repeated statements, veiled threats, or
diplomatic coercion.

That, however, is not the case on the record before the Tribunal.

Accordingly, the Tribunal concludes that China’s diplomatic statements to the Philippines
regarding their respective rights, although incorrect with respect to the law, do not constitutebreaches of the Convention.
706. The Tribunal reaches the same conclusions with respect to the communications of the Chinese
Embassy in Manila with Nido Petroleum Company (see paragraph 664 above). Even taking
Nido’s account of that conversation as fully accurate, the most that can be attributed to theChinese diplomat in question is the statement that “all areas within [China’s ‘9-dash line’] map
are being claimed by PRC, including those areas covered by Nido’s existing service contracts
with the Philippine Government.”

727

There is no evidence before the Tribunal that theconversation included any efforts to induce Nido to cease operations in the SC58 block, any
indication of adverse consequences if Nido declined to do so, or even a request that Nido refrainfrom further operations. On the evidence before the Tribunal, China’s representative merely
informed Nido of China’s claim. When Nido suggested that China take the matter up with thePhilippine Department of Energy, China’s representative left and did not return. The Tribunal

considers that China’s actions in merely informing a private party of its claims in the South
China Sea do not, without more,728 constitute breaches of the Convention.
707. The Tribunal reaches a different conclusion, however, with respect to China’s actions inconnection with the survey operations of M/V Veritas Voyager. The Tribunal accepts thePhilippine Navy’s contemporaneous record of events as accurate and notes that the key passageof that account records as follows:
two (2) (Chinese) surveillance vessels approached MV Veritas Voyager again and informed
them that they are operating in the territorial waters of China under the UN charter. The
Party Manager replied that the Veritas Voyager was operating in the territory of thePhilippines with all the required permits. The Marine surveillance vessels then ordered the
Veritas Voyager to stop the production and leave the area. After consultation with CGGV
senior management, the Party Manager, informed the Chinese Surveillance vessels thatthey would stop production and proceed to the recovery area. 729

708. On these facts, the Tribunal does not consider that China’s actions were limited to stating its
understanding of the Parties’ respective rights.

Rather, China acted directly to induce

M/V Veritas Voyager to cease operations and to depart from an area that constitutes part of thecontinental shelf of the Philippines. Prior to this, the Tribunal notes, China was unequivocallyaware that there existed a difference of views regarding the Parties’ respective entitlements in
the South China Sea and, in particular, in the area of Reed Bank. On the account of China’s
own diplomats (as memorialised at the time by the Philippines), “China has made repeated
representations with the Philippines on the GSEC 101 issue since 2002.”730 A dispute on thisissue was evident, and the approach called for by the Convention was for the Parties to seek toresolve their differences through negotiations or the other modes of dispute resolution identified
in Part XV of the Convention and the UN Charter. Instead, China sought to carry out its own
understanding of its rights through the actions of its marine surveillance vessels. China having
done so, the Tribunal considers that China’s actions amount to a breach of Article 77 of theConvention, which accords sovereign rights to the Philippines with respect to its continental
shelf in the area of Reed Bank (the area in question).

728

The Tribunal notes that Nido’s account also indicates that, approximately one year later, it was informed
by a Chinese subcontractor that the subcontractor would not work in the area of the SC54 and SC58
blocks due to China’s territorial claims. This is an action by a private party. There is no evidence before
the Tribunal that would suggest that the actions of Nido’s subcontractor are attributable to China.

ii.

Acts in relation to Living Resources709. In the case of living resources, the Tribunal notes that the Philippines has, again, identified
several distinct types of conduct on the part of China that it considers to violate its sovereign
rights in the exclusive economic zone. First, the Philippines objects to China’s extension of its
jurisdiction over fisheries in the South China Sea through the 2012 moratorium on fishing in thearea north of 12° N latitude and through the Hainan Regulation. Second, the Philippines objects
to China’s prevention of fishing by Philippine vessels at Mischief Reef and Second Thomas
Shoal.
710. With respect to China’s assertion of fisheries jurisdiction, the Tribunal asked the Philippines toclarify “[w]hether China has sought to enforce either the May 2012 fishing ban or the
Regulations for the Management of Coastal Border Security in Hainan Province against
Philippines fishing vessels and the specifics of such enforcement.” 731

In response, thePhilippines asserted that China had done so.732 As evidence of this, the Philippines advanced aNote Verbale from China in which China asserted its right to impose a fishing moratorium in
the South China Sea, requested the Philippines to educate its fishermen to comply with themoratorium, and cautioned the Philippines that “Chinese law-enforcing authorities will
strengthen their maritime patrols and other law-enforcing actions, investigate and punish therelevant fishing vessels and fishermen who violate the fishing moratorium in accordance withthe law.”733 The Philippines also noted that “[s]tatements like that have a deeply chilling effecton Filipino fishermen and their activities.”734
711. As an initial matter, the Tribunal notes that the Note Verbale invoked by the Philippines dates
from 6 July 2015.

To the extent that diplomatic correspondence constitutes evidence ofenforcement actions taken by China, the Note Verbale would relate, if at all, to the fishing
moratorium imposed by China in the summer of 2015. The Philippines did not invoke any otherevidence that would establish that the 2012 fishing moratorium was enforced against any
Philippine fishing vessel in any area falling in the Philippines’ exclusive economic zone, nor has
the Tribunal seen any such indication in the record before it.

Accordingly, the Tribunal

considers that the relevant question is whether China’s 2012 promulgation of the fishing731

moratorium itself, irrespective of whether the moratorium was directly enforced, infringes on
the rights of the Philippines and constitutes a breach of the Convention.
712. On this question, the Tribunal considers that the adoption of legislation or the promulgation of
the fishing moratorium as a regulation differs from the mere assertion of China’s rights in its
diplomatic communications with the Philippines. Examining the scope of application specified
in the moratorium itself,735 and noting the public reports to the effect that the ban would apply in“most parts of the South China Sea” and in the “areas north of the 12th parallel, including
Huangyan Island [Scarborough Shoal],” 736 the Tribunal concludes that the moratorium wasintended to apply to areas of the Philippines’ exclusive economic zone north of 12° N latitude
and was not limited to Chinese flagged vessels. In contrast to mere statements, the fishing
moratorium established a realistic prospect that Filipino fisherman, seeking to exploit theresources of the Philippines’ exclusive economic zone, could be exposed to the punitive
measures spelled out in the moratorium, including the possible confiscation of the fishing vesselin question. The Tribunal considers that such developments may have a deterring effect on
Filipino fishermen and their activities. In effect, the 2012 fishing moratorium constituted an
assertion by China of jurisdiction in areas in which jurisdiction over fisheries is reserved to thePhilippines through the operation of the provisions of the Convention concerning the exclusive
economic zone. The Tribunal considers that such an assertion of jurisdiction amounts to abreach of Article 56 of the Convention, which accords sovereign rights to the Philippines withrespect to the living resources of its exclusive economic zone.
713. The Tribunal reaches a different conclusion with respect to the Hainan Regulation. As an initialmatter, the Tribunal sees no provision on the face of the Hainan Regulation that would restrict
the rights of the Philippines over the resources of its exclusive economic zone. Moreover, theTribunal notes that China has publicly stated that the regulation applies only within 12 nautical
miles of Hainan.737 The Tribunal does not consider that the Hainan Regulation infringes on therights of the Philippines or amounts to a breach of the provisions of the Convention concerning
the exclusive economic zone.
714. Finally, with respect to China’s alleged prevention of Philippine vessels from fishing at
Mischief Reef and Second Thomas Shoal, the Tribunal notes that there is a distinct lack of

284

The South China Sea Arbitration
Award of 12 July 2016evidence on this question in the record before it. Prior to the hearing, the Tribunal invited thePhilippines to clarify “the specifics of the actions taken by China” to prevent fishing by
Philippines vessels at Mischief Reef and Second Thomas Shoal.738 The Philippines has statedwith respect to Mischief Reef that “China has acted to prevent Filipino fishermen from fishing
there ever since it took physical control of the reef in 1995.”739 The Philippines said China’s
actions to restrict Filipino fishing at Second Thomas Shoal “have also primarily taken place
within 12 miles of Second Thomas Shoal ever since China took de facto control of that featurein May 2013.”740 The Philippines further stated that “Chinese marine surveillance vessels, navy
warships and fishing administration vessels have surrounded the shoal. They have blocked
Philippine vessels, including civilian vessels, from approaching Second Thomas Shoal.” 741
With respect to evidence of these assertions, however, the Tribunal has reviewed the record
identified by the Philippines and is not able to identify a single documented instance in which
Chinese Government vessels acted to prevent Filipino fishermen from fishing at either Second
Thomas Shoal or Mischief Reef.
715. The Tribunal hastens to emphasise that the absence of evidence on this point in the record
before it does not mean that such events did not occur or that China’s actions may not otherwise
have dissuaded Filipino fishermen from approaching Second Thomas Shoal and Mischief Reef.
The Tribunal can readily imagine that the presence of Chinese law enforcement vessels at both
locations, combined with China’s general claim to fisheries jurisdiction in the South China Sea,
could well lead Filipino fishermen to avoid such areas. The Tribunal is not, however, preparedto find a violation of the Convention on this basis. The Tribunal considers that the Philippines
has not established that China has prevented Filipino fishermen from fishing at Mischief Reef orSecond Thomas Shoal and that, in this respect, the provisions of the Convention concerning
fisheries are not implicated.

716. Based on the considerations outlined above, the Tribunal finds that China has, through theoperation of its marine surveillance vessels with respect to M/V Veritas Voyager on
1 to 2 March 2011 breached Article 77 of the Convention with respect to the Philippines’
sovereign rights over the non-living resources of its continental shelf in the area of Reed Bank.
The Tribunal further finds that China has, by promulgating its 2012 moratorium on fishing in
the South China Sea, without exception for areas of the South China Sea falling within the
exclusive economic zone of the Philippines and without limiting the moratorium to Chinese
flagged vessels, breached Article 56 of the Convention with respect to the Philippines’
sovereign rights over the living resources of its exclusive economic zone.

ALLEGED FAILURE TO PREVENT CHINESE NATIONALS FROM EXPLOITING THE
PHILIPPINES’ LIVING RESOURCES (SUBMISSION NO. 9)
1.

Introduction

717. In this Section, the Tribunal addresses the Parties’ dispute concerning China’s toleration offishing by Chinese vessels in the areas of the South China Sea located within the Philippines’
exclusive economic zone. This dispute is reflected in Submission No. 9 of the Philippines,
which requests the Tribunal to declare that:(9)2.

China has unlawfully failed to prevent its nationals and vessels from exploiting theliving resources in the exclusive economic zone of the Philippines;

Factual Background718. The Philippines’ allegations in respect of this Submission concern developments at Mischief
Reef and Second Thomas Shoal, both of which are low-tide elevations lying within 200 nautical
miles of the Philippines’ baselines.
719. Since 3 May 2013, China has maintained a significant presence of naval and CMS vessels near
Second Thomas Shoal. As reported by the Armed Forces of the Philippines:
Starting 03 May 2013, China maintained the presence of at least two (2) vessels at Ayungin
Shoal [Second Thomas Shoal]. Since then, two (2) PLA Navy frigates (BN 562 and 563)
and five (5) CMLEA vessels (CMS BN 84, 167, 75, 71 and 8002) have been monitored
deployed in the shoal and its outlying areas on a rotation basis. 742

720. These government vessels have been accompanied by a number of fishing vessels. Thus on
4 May 2013, the Philippines’ marine detachment maintained on the wreck of the BRP Sierra
Madre on Second Thomas Shoal reported the presence of “1 PLA Navy, 2 CMS, and 1 Chinese
steel-hulled fishing vessels . . . in the vicinity of Ayungin Shoal.”743 On 11 May 2013, theArmed Forces of the Philippines reported the presence of:•

PLA Navy Frigate at vicinity 6 [nautical miles] northwest off Ayungin Detachment.

•

2 CMS vessels at vicinity 7 [nautical miles] southeast off Ayungin Detachment;•

1 CMS vessel at vicinity 4 [nautical miles] north off Ayungin Detachment.

•

1 Hainan-type Fishing Vessel at vicinity 3 [nautical miles] northeast off Ayungin
Detachment. and,742

And on 16 May 2013, the Philippines Air Force reported several fishing vessels apparently at
work in the vicinity of Second Thomas Shoal:

believed to be gathering corals and clams and dredging in the shoal. 745

721. The Philippines’ military has likewise reported the presence of Chinese fishing vessels, escorted
by Chinese Government ships, at Mischief Reef, where China has maintained a presence since1995. A Philippines’ report from May 2013 notes as follows:at least 33 Chinese fishing vessels were said to have been fishing at the Chinese-occupied
Mischief Reef and nearby features since 08 May 2013, escorted by a PLA Navy ship and
CMS vessels . . . . 746

3.

The Philippines’ Position

722. The Philippines submits that the Tribunal has jurisdiction to consider its Submission No. 9, forthe same reasons set out with respect to its Submission No. 8 (see paragraphs 681 to 682 above).
723. On the merits, the Philippines argues that China has violated its obligations under Article 56 of
the Convention to respect the sovereign rights and jurisdiction of the Philippines by failing toprevent its nationals and vessels from exploiting the living resources of the Philippines’
exclusive economic zone.
724. The Philippines argues that as China has established de facto control over areas of the South
China Sea, it has acted to prevent fishing by Philippine vessels, while tolerating fishing by
Chinese nationals and vessels, including in areas that comprise the Philippines’ exclusive
economic zone. Thus, according to the Philippines, “since 1995, when China seized and began
occupying Mischief Reef, just 126 [nautical miles] off the coast of Palawan, it has prevented
Philippines vessels from fishing there. In contrast, Chinese fishing vessels under China’s
protection have fished freely in the adjacent waters, even though they are part of thePhilippines’ EEZ.”747 Similarly, the Philippines argues, “after China took de facto control ofSecond Thomas Shoal in May 2013, it began interfering with Philippine fishing activities in the744

area, while allowing fishing by Chinese vessels, notwithstanding that Second Thomas Shoal ispart of the Philippines’ EEZ.”748
725. Pursuant to Article 56 of the Convention, the Philippines argues, “States have an obligation,acting in good faith, to take the measures necessary to prevent their nationals from exploiting
the living resources in the EEZ of another State party.”749 In the Philippines’ view, the scope of
this duty “extends to such actions as are reasonably necessary to give full effect to the exclusive
rights of the coastal State conferred by Article 56.”750
726. The Philippines relies in particular on the Fisheries Advisory Opinion of the International
Tribunal for the Law of the Sea,751 emphasising the portions of that decision that recognise thata State has an obligation to ensure that its nationals and vessels comply with any conditions or
regulations imposed by the coastal State when fishing within its exclusive economic zone and toensure that vessels flying its flag do not engage in illegal, unreported, and unregulated (“IUU”)
fishing.752 The Philippines also adopts the definition of the “obligation to ensure” set out in theAdvisory Opinion, which provides that such an obligation is an obligation “to deploy adequatemeans, to exercise best possible efforts, to do the utmost.”753
727. Applying this standard to the activities of Chinese fishermen, the Philippines submits that:
Instead of adopting measures to prevent fishing, Chinese authorities have actively
encouraged illegal and unregulated fishing by Chinese vessels in the Philippines’ EEZ. In
circumstances in which China has explicitly authorised its own vessels to engage in fishingactivities in the EEZ of the Philippines, it simply cannot be said that China has “deployedadequate means” to prevent such fishing activity. Nor can it be said that China has“exercise[d] best possible efforts” to prevent illegal and unregulated fishing activities. And
it certainly cannot be said that China has done “the utmost, to obtain [the] result” that its
vessels shall not fish in the Philippines’ EEZ. 754

728. The Philippines concludes that “China is not per se responsible for the actions of its fishermen,‘but it is responsible for its own failure to control their illegal and damaging activities.’”755 The

China’s Position

729. As far as the Tribunal is aware, China has never directly addressed the allegation that it has
unlawfully permitted its fishermen to fish within the Philippines’ exclusive economic zone atSecond Thomas Shoal or Mischief Reef.
730. Rather, the position that consistently appears in China’s contemporaneous statements is that it
does not consider the Philippines to have rights in the area of Second Thomas Shoal andMischief Reef. Thus, in its diplomatic correspondence with the Philippines, China has statedgenerally that:
China possesses indisputable sovereignty over Nansha Islands and its adjacent waters, andthe construction, usage and other activities at the relevant islands, reefs, shoals and sands
are actions completely within the scope of China’s sovereignty, sovereign rights andjurisdiction.757

731. China has repeatedly demanded that the Philippines withdraw its personnel from Second
Thomas Shoal in the following terms:
The Chinese side demands the Philippine side withdraw all its personnel and facilities from
China’s islands and reefs, and honor its commitment to tow away its illegally “grounded”
vessel on China’s Ren’ai Jiao [Second Thomas Shoal] . . . .758

732. Likewise, China has stated that “China has indisputable sovereignty over Nansha Islands andtheir adjacent waters, Meiji Jiao [Mischief Reef] . . . included.”759

The Tribunal’s Considerations(a)

The Tribunal’s Jurisdiction

733. In its Award on Jurisdiction, the Tribunal deferred any final decision with respect to its
jurisdiction concerning the Philippines’ Submission No. 9, for the same reason that it deferredconsideration of its jurisdiction with respect to the Philippines’ Submission No. 8 (seeparagraphs 690 to 691 above). Specifically, the Tribunal considered that its jurisdiction overthese Submissions was contingent on whether Mischief Reef and Second Thomas Shoal were
low-tide elevations and whether any other feature claimed by China is capable of generating an
entitlement to an exclusive economic zone in the area of those features that would overlap theentitlement of the Philippines.
734. Having determined that Mischief Reef and Second Thomas Shoal are both low-tide elevations,and that no high-tide feature in the Spratly Islands is capable of generating an entitlement to an
exclusive economic zone, the Tribunal concludes that it has jurisdiction with respect to thePhilippines’ Submission No. 9 for the same reason already stated with respect toSubmission No. 8 (see paragraphs 692 to 695 above).

(b)

The Law Applicable to China’s Supervision of its Fishing Vessels

735. The Tribunal has held that Mischief Reef and Second Thomas Shoal are low-tide elevations
located within areas where only the Philippines possesses possible entitlements to maritime
zones under the Convention. The relevant areas can only constitute the exclusive economic
zone of the Philippines. Accordingly, the Philippines—and not China—possesses sovereign
rights with respect to resources in these areas, and the law relevant to Chinese fishing activities
at these reef formations is the law governing fishing by the vessels of one State in the exclusive
economic zone of another.
736. In this respect, Article 61(1) of the Convention provides that “[t]he coastal State shall determine
the allowable catch of the living resources in its exclusive economic zone.” The remainder of
Article 61 concerns the process through which the coastal State will determine the allowable
catch.
737. Article 62 of the Convention then outlines the circumstances in which vessels of other States
will have access to the fisheries of a State’s exclusive economic zone. Article 62(2) provides
759

Note Verbale from the Embassy of the People’s Republic of China in Manila to the Department of
Foreign Affairs, Republic of the Philippines, No. 15 (PG)-214 (28 June 2015) (Annex 689).

291

The South China Sea Arbitration
Award of 12 July 2016that “[w]here the coastal State does not have the capacity to harvest the entire allowable catch, it
shall, through agreements or other arrangements and pursuant to the terms, conditions, laws andregulations referred to in paragraph 4, give other States access to the surplus of the allowable
catch . . . .” Article 62(3) then provides guidance on the factors to be considered in according
access to other States.
738. These provisions make clear that it is the Philippines that controls the process of granting andregulating access to the fisheries of its exclusive economic zone, subject to the provisions of theConvention in doing so. It is thus for the Philippines to determine the allowable catch forfisheries within its exclusive economic zone. If after determining the allowable catch, thePhilippines also determines that it lacks the capacity to fully harvest the allowable catch, it mustallow other States access to the fishery.
739. Article 62(4) then imposes an obligation on nationals of other States fishing in the exclusive
economic zone to comply with the laws and regulations of the coastal State and sets out anillustrative list of the areas that may be regulated. Article 62(4) provides in full as follows:
Nationals of other States fishing in the exclusive economic zone shall comply with theconservation measures and with the other terms and conditions established in the laws andregulations of the coastal State. These laws and regulations shall be consistent with thisConvention and may relate, inter alia, to the following:(a)licensing of fishermen, fishing vessels and equipment, including payment of feesand other forms of remuneration, which, in the case of developing coastal States,
may consist of adequate compensation in the field of financing, equipment andtechnology relating to the fishing industry;(b)

determining the species which may be caught, and fixing quotas of catch, whether in
relation to particular stocks or groups of stocks or catch per vessel over a period oftime or to the catch by nationals of any State during a specified period;(c)regulating seasons and areas of fishing, the types, sizes and amount of gear, and thetypes, sizes and number of fishing vessels that may be used;(d)fixing the age and size of fish and other species that may be caught;(e)specifying information required of fishing vessels, including catch and effort
statistics and vessel position reports;(f)requiring, under the authorization and control of the coastal State, the conduct ofspecified fisheries research programmes and regulating the conduct of such research,
including the sampling of catches, disposition of samples and reporting of associatedscientific data;(g)

the placing of observers or trainees on board such vessels by the coastal State;(h)the landing of all or any part of the catch by such vessels in the ports of the coastal

enforcement procedures.

740. Article 62(4) thus expressly requires Chinese nationals to comply with the licensing and otheraccess procedures of the Philippines within any area forming part of the exclusive economic
zone of the Philippines. The Convention imposes an obligation directly on private parties
engaged in fishing that would apply to Chinese nationals and vessels engaged in fishing at
Mischief Reef and Second Thomas Shoal and require them to comply with the terms andconditions of the laws and regulations of the Philippines.
741. The Convention also imposes obligations on States Parties with respect to activities in the
exclusive economic zone of other States. Article 58(3) of the Convention provides as follows:
In exercising their rights and performing their duties under this Convention in the exclusive
economic zone, States shall have due regard to the rights and duties of the coastal State andshall comply with the laws and regulations adopted by the coastal State in accordance withthe provisions of this Convention and other rules of international law in so far as they are
not incompatible with this Part.

742. The nature of the obligation to have “due regard to the rights and duties” of another State wasconsidered by the tribunal in the Chagos Marine Protected Area Arbitration in the context ofArticle 56(2) (concerning the reversed situation of the regard owed by the coastal State to therights and duties of other States within its exclusive economic zone). The tribunal in that matterreasoned as follows:
the ordinary meaning of “due regard” calls for the [first State] to have such regard for therights of [the second State] as is called for by the circumstances and by the nature of thoserights. The Tribunal declines to find in this formulation any universal rule of conduct. The
Convention does not impose a uniform obligation to avoid any impairment of [the second
State’s] rights; nor does it uniformly permit the [first State] to proceed as it wishes, merely
noting such rights. Rather, the extent of the regard required by the Convention will depend
upon the nature of the rights held by [the second State], their importance, the extent of the
anticipated impairment, the nature and importance of the activities contemplated by the[first State], and the availability of alternative approaches. 760

743. In the context of the duties of a flag State with respect to fishing by its nationals, theInternational Tribunal for the Law of the Sea interpreted the obligation of due regard, when readin conjunction with the obligations directly imposed upon nationals by Article 62(4), to extend
to a duty “to take the necessary measures to ensure that their nationals and vessels flying their

Award of 12 July 2016flag are not engaged in IUU fishing activities.”761 The Fisheries Advisory Opinion goes on tonote that:the obligation of a flag State . . . to ensure that vessels flying its flag are not involved in
IUU fishing is also an obligation “of conduct”. . . . as an obligation “of conduct” this is a“due diligence obligation”, not an obligation “of result”. . . . The flag State is under the“due diligence obligation” to take all necessary measures to ensure compliance and toprevent IUU fishing by fishing vessels flying its flag. 762

744. The Tribunal agrees with the Fisheries Advisory Opinion in this respect. Given the importanceof fisheries to the entire concept of the exclusive economic zone, the degree to which theConvention subordinates fishing within the exclusive economic zone to the control of thecoastal State, and the obligations expressly placed on the nationals of other States by Article
62(4) of the Convention, the Tribunal considers that anything less than due diligence by a Statein preventing its nationals from unlawfully fishing in the exclusive economic zone of anotherwould fall short of the regard due pursuant to Article 58(3) of the Convention.
(c)

The Activities of Chinese Fishing Vessels at Mischief Reef and Second Thomas
Shoal745. With respect to Chinese activities at Mischief Reef and Second Thomas Shoal, the Tribunal
notes that it has limited evidence before it. The record of Chinese fishing at these features isrestricted to reports from the Armed Forces of the Philippines and confined to a single period in
May 2013.

The most information is available from Second Thomas Shoal, where thePhilippines maintains a small marine detachment, but even there it is apparent that thePhilippines is able to observe the activities of China’s vessels only from a distance and has notsought to enforce its regulations or restrict the activities of Chinese vessels. China’s de facto
control over the waters surrounding both features effectively limits the information available to
the Philippines and to this Tribunal.
746. Despite these limitations, the Tribunal is prepared to accept that the account of events provided
by the Armed Forces of the Philippines is accurate and that Chinese fishing vessels,
accompanied by the ships of CMS, were engaged in fishing at both Mischief Reef and Second
Thomas Shoal in May 2013. It does so for two reasons.
747. First, the Tribunal notes that China has asserted sovereign rights and jurisdiction in the South
China Sea, generally, and has apparently not accepted these areas as part of the Philippines’

exclusive economic zone (see paragraphs 730 to 732 above). Indeed, the Tribunal notes that
China has issued a “Nansha Certification of Fishing Permit” to its nationals, 763 which the
Tribunal understands to extend to the area of Mischief Reef and Second Thomas Shoal. The
Tribunal considers this assertion of jurisdiction over the activities of (at least) Chinese
fishermen in the South China Sea to support the Philippines’ evidence that Chinese vessels haveindeed been fishing at Mischief Reef and Second Thomas Shoal.
748. Second, the pattern of Chinese fishing activity at Mischief Reef and Second Shoal is consistent
with that exhibited at other reef formations for which the Tribunal has information. Thus, in thecase of Subi Reef, the Philippines reports as follows:a Chinese fishing fleet composed of 30 vessels under a unified command sailed on 06 May
2013 from Hainan province, China to the disputed Spratly Islands in the West Philippine
Sea for a “40-day operation.” The “40-day operation” is the second of its kind organizedby local fishery associations after Sansha City was established by China in June 2012.
Each vessel in the fleet, equipped with all-weather communication devices, weighs morethan 100 metric tons. Further, a 4,000-ton supply ship and a 1,500-ton transport ship were
supplying the fishing vessels with fuel, food, water and other necessities. 764

749. Meanwhile, in the case of Scarborough Shoal, the Tribunal has ample, corroborated evidence offishing by Chinese vessels working in apparently close coordination with government vessels
from CMS and the Fisheries Law Enforcement Command (“FLEC”) in the period of April andMay 2012. 765 These incidents are discussed in detail in connection with the Philippines’
Submissions No. 11 and 13.
750. The Tribunal notes that Subi Reef and Scarborough Shoal are not, as a legal matter, comparable
to Mischief Reef and Second Thomas Shoal. Subi Reef lies within the territorial sea of Sandy
Cay on the reefs adjacent to Thitu (see paragraphs 367 to 373 above) while Scarborough Shoal
is a high-tide feature that would generate its own entitlements to a territorial sea

295

The South China Sea Arbitration
Award of 12 July 2016(see paragraphs 333 to 334 above). The Tribunal has not addressed—and will not address—thequestion of which State has sovereignty over Sandy Cay, Thitu, or Scarborough Shoal andwould thus have an entitlement to the surrounding territorial sea.
751. In contrast, Mischief Reef and Second Thomas Shoal are not capable of generating entitlements
to maritime zones and can only form part of the Philippines’ exclusive economic zone.
Nevertheless, in light of the fact that China has not accepted these areas as part of thePhilippines’ exclusive economic zone, the Tribunal considers the similarities in Chinese fishingactivities at all of these features to be a significant indication of what has taken place atMischief Reef and Second Thomas Shoal.
752. The Tribunal expects, from the general positions of the Parties, that Chinese vessels havecontinued to fish at Mischief Reef and Second Thomas Shoal since May 2013. The Tribunal
does not, however, have the direct evidence before it that would enable it to draw such a
conclusion for the period subsequent to May 2013.
*753. Having established that Chinese vessels have been engaged in fishing at Mischief Reef andSecond Thomas Shoal in May 2013, the Tribunal considers that China has failed to show thedue regard called for by Article 58(3) of the Convention to the Philippines’ sovereign rights
with respect to fisheries within its exclusive economic zone.
754. In many cases, the precise scope and application of the obligation on a flag State to exercise due
diligence in respect of fishing by vessels flying its flag in the exclusive economic zone ofanother State may be difficult to determine. Often, unlawful fishing will be carried out covertly,
far from any official presence, and it will be far from obvious what the flag State could
realistically have done to prevent it. That, however, is not the case here.
755. Chinese fishing vessels have in all reported instances been closely escorted by government
CMS vessels. The actions of these ships constitute official acts of China and are all attributable
to China as such. Indeed, the accounts of officially organised fishing fleets from Hainan at Subi
Reef and the close coordination exhibited between fishing vessels and government ships at
Scarborough Shoal support an inference that China’s fishing vessels are not simply escorted andprotected, but organised and coordinated by the Government. In any event, there can be noquestion that the officers aboard the Chinese Government vessels in question were fully awareof the actions being taken by Chinese fishermen and were able to halt them had they chosen to
do so.

296

The South China Sea Arbitration
Award of 12 July 2016756. The obligation to have due regard to the rights of the Philippines is unequivocally breachedwhen vessels under Chinese Government control act to escort and protect Chinese fishingvessels engaged in fishing unlawfully in the Philippines’ exclusive economic zone.
(d)Conclusion

757. Based on the considerations outlined above, the Tribunal finds that China has, through theoperation of its marine surveillance vessels in tolerating and failing to exercise due diligence toprevent fishing by Chinese flagged vessels at Mischief Reef and Second Thomas Shoal in May
2013, failed to exhibit due regard for the Philippines’ sovereign rights with respect to fisheries
in its exclusive economic zone.

Accordingly, China has breached its obligations under

Article 58(3) of the Convention.

CHINA’S ACTIONS IN RESPECT OF TRADITIONAL FISHING AT SCARBOROUGH SHOAL(SUBMISSION NO. 10)
1.

Introduction

758. In this Section, the Tribunal addresses the Parties’ dispute concerning China’s actions withrespect to the traditional fishing activities of Philippine nationals at Scarborough Shoal. This
dispute is reflected in the Philippines’ Submission No. 10, which provides as follows:(10)

China has unlawfully prevented Philippine fishermen from pursuing theirlivelihoods by interfering with traditional fishing activities at Scarborough Shoal;

759. In its Award on Jurisdiction, the Tribunal held that this Submission reflects a dispute that does
not concern maritime boundary delimitation and is not barred from the Tribunal’s consideration
by any requirement of Section 1 of Part XV.766 The Tribunal noted that the Philippines had
clarified that the activities alleged all occurred within the 12-nautical-mile territorial sea
generated by Scarborough Shoal and that, accordingly, determination of Submission No. 10
does not depend on the characterisation of the feature as a rock or an island under Article 121 of
the Convention.767 Nor do Articles 297 and 298 of the Convention apply in the territorial sea torestrict the Tribunal’s jurisdiction with respect to fisheries and law enforcement.768 In addition,
the Tribunal noted that traditional fishing rights “may exist even within the territorial waters ofanother State,” and considered that its jurisdiction to address this dispute is not dependent on
any prior determination of sovereignty over Scarborough Shoal. 769

In consequence, theTribunal concluded that it has jurisdiction to address the matters raised in the Philippines’
Submission No. 10 “to the extent that the claimed rights and alleged interference occurred
within the territorial sea of Scarborough Shoal.”7702.

Factual Background760. The facts underlying the present Submission concern the conduct of Chinese Government
vessels at Scarborough Shoal since 2012, and in particular their interactions with Philippine
fishermen proximate to the feature.

Award of 12 July 2016(a)

Traditional Fishing by Philippine Fishermen at Scarborough Shoal

761. Even as several States have claimed sovereignty over Scarborough Shoal, there is evidence thatthe surrounding waters have continued to serve as traditional fishing grounds for fishermen, 771
including those from the Philippines, Viet Nam, and China (including from Taiwan). The
background to a Philippine Navy report in the record before the Tribunal describes ScarboroughShoal as “a traditional fishing ground of fishermen from neighbouring Asian countries that havebeen heading to this area for its rich marine resources. Both foreign and local fishermen areamong those who venture to this atoll and they would be fishing there for about a week ormore.” 772 China’s Foreign Ministry Spokesperson has likewise asserted that “[t]he waters
surrounding the Huangyan Island [Scarborough Shoal] has been a traditional fishing ground for
Chinese fishermen.

Since ancient times, Chinese fishermen have been fishing in waters

surrounding the Island.” 773 Affidavits from Filipino fishermen proffered by the Philippines
describe having seen nationals of other States, including Viet Nam and China (including from
Taiwan), fishing at Scarborough Shoal.774
762. Historical cartography evidences a connection between Scarborough Shoal and the Philippine
mainland. A map of the Philippines produced in 1734 included the shoal;775 another producedin 1784 labelled Scarborough Shoal as “Bajo de Masinloc”.776 Other documents provided by

China’s Intermittent Prevention of Fishing by Philippine Vessels at
Scarborough Shoal (May 2012 to Present)

764. Beginning in April 2012, a series of incidents occurred between Philippine and Chinese vessels
at Scarborough Shoal that heightened tensions between the Parties. Philippine authorities
reported increasing numbers of Chinese fishing vessels at Scarborough Shoal and stepped up
inspections in response to indications that Chinese vessels were employing destructive fishingmethods and harvesting endangered giant clams, corals, and sea turtles. China increased thedeployment of its own FLEC and CMS vessels in response, leading to a series of incidents
between Chinese and Philippine vessels on 10 April 2012, 783 28 April 2012, 784 and

detail with respect to Submission No. 11 (see paragraphs 815 to 993 below). The incidents
between Philippine and Chinese vessels are discussed in connection with the Philippines’
Submission No. 13 (see paragraphs 1044 to 1109 below).
765. Efforts to negotiate a mutual withdrawal of government vessels were not successful,786 and by
early June 2012, China had “deployed about 28 utility boats across the southeast entrance of the
shoal and rigged them together by rope to establish a makeshift boom or barrier,” blocking theentrance to the lagoon of Scarborough Shoal.787
766. The record indicates that, as tensions intensified, fishermen active in the vicinity of ScarboroughShoal were affected by the Parties’ dispute.

In a memorandum dated 2 June 2012, theCommander of the Philippines’ “Naval Forces Northern Luzon” wrote that China’s barrier was“likely designed to discourage if not prevent the ingress/egress of Philippine vessels to the

Philippine fishermen, who use the shoal as a shelter during the typhoon season to mitigate theeffects of the southwest monsoon.”789
767. Similarly, a memorandum submitted by the Director of the Philippine Bureau of Fisheries andAquatic Resources states:
Since April 2012, when the Chinese took control of Scarborough Shoal, Filipinos find it
difficult to enter the shoal because the Chinese law enforcement vessels have created a “nofishing zone” around it. Chinese patrol vessels enforce this zone by threatening Filipino
fishermen who attempt to fish at Scarborough.
This conduct of the Chinese government, together with its enactment of new laws, such as
the 2012 Hainan Regulations and the 2012 fishing ban, have created a deep sense of fear
among Filipino fishermen that has significantly curtailed their fishing activities andseverely impacted their ability to earn a livelihood.790

768. The accounts provided by Filipino fishermen confirm their exclusion from fishing grounds at
Scarborough Shoal. Mr. Crispen Talatagod, a retired fisherman from the municipality of
Infanta in Pangasinan province, stated:
I stopped fishing in 2012 because we were prohibited from fishing there by the Chinese. I
remember that when my companions and I went to Scarborough Shoal, we were met by anarmed member of [the] Chinese Coast Guard. The guard told us that they own ScarboroughShoal and he prevented us from fishing there. We were surprised and afraid at that time.
We tried to hide and wait for nighttime before starting to fish, but the Chinese were able toanticipate this. Again, they prohibited us from fishing in Scarborough Shoal. I was notable to return since then.791

Similarly, Mr. Tolomeo Forones, a resident of Masinloc, recalled:
No one fishes there anymore. I tried to go back to Scarborough Shoal last June 2012 andJuly 2013 with some members of the media. When we arrived only Chinese Coat Guard
vessels were there to drive away anyone who attempts to go in. 792

Additionally, Mr. Cecilio Taneo, of Masinloc, said:
The Filipinos were prohibited by the Chinese from entering the Scarborough Shoal. While
the Filipinos are still far from reaching the Scarborough Shoal, the Chinese already gave asignal not to proceed further. The Chinese used water cannons against the Filipinos. 793

769. During other periods, however, fishermen were occasionally permitted to continue to fish at the
shoal. Opportunities to do so appear to have been limited. Mr. Jowe Legaspi, a fisherman whobegan fishing at Scarborough Shoal in 1994,794 reported:

The Philippines’ Position

771. The Philippines argues that China violated its obligations under Article 2(3) of the Convention,and considers this conclusion supported indirectly by reference to Articles 51(1) and 62(3) ofthe Convention.799 Additionally, the Philippines submits that China has violated Articles 279800
and 300 of the Convention.801(a)Article 2(3) of the Convention

772. The Philippines maintains that, by preventing Filipino fishermen from fishing in the waters of
Scarborough Shoal,802 China has violated Article 2(3) of the Convention, which provides that“sovereignty over the territorial sea is exercised subject to this Convention and to other rules ofinternational law.”803

Award of 12 July 2016

Marine Protected Area Arbitration, 804 in which the tribunal “unanimously rejected” theargument that Article 2(3) was “descriptive” only.805
774. In this regard, the Philippines also recalls the individual opinion of Judge Alvarez in the
Anglo-Norwegian Fisheries case, acknowledging that a State might “determine the extent of its
territorial sea,” on the condition that such determination “does not infringe on rights acquired byother states.” 806

Finally, the Philippines regards instructive the writings of Sir Gerald

Fitzmaurice, who framed traditional fishing rights in the following terms:[I]f the fishing vessels of a given country have been accustomed from time immemorial, orover a long period, to fish in a certain area, on the basis of the area being high seas andcommon to all, it may be said that their country has through them . . . acquired a vested
interest that the fisheries of that area should remain available to its fishing vessels (ofcourse on a non-exclusive basis)—so that if another country asserts a claim to that area as
territorial waters, which is found to be valid or comes to be recognized, this can only besubject to the acquired rights of the fishery in question, which must continue to berespected.807

Accordingly, the Philippines deems Article 2(3) to impose substantive obligations informed bygeneral rules of international law, including the preservation of pre-existing rights.
775. One such rule, the Philippines submits, is the protection of traditional fishing rights of the sortraised in its Submission No. 10; there is, in other words, “a general rule of international law that
requires a state to respect long and uninterrupted fishing by the nationals of another state in its
territorial sea.”808
776. In the Philippines’ view, the protection of traditional fishing rights is firmly established innational and international jurisprudence. In The Paquete Habana, for instance, the Philippines
notes that the U.S. Supreme Court recognised, then “adopted and applied the rule of customaryinternational law that exempts fishing vessels from prize capture in wartime.”809
777. From arbitral practice, the Philippines recalls the holding in the Eritrea v. Yemen arbitration,that required Yemen to “ensure that the traditional fishing regime of free access and enjoyment
for the fishermen of both Eritrea and Yemen shall be preserved for the benefit of the lives and804

livelihoods of this poor and industrious order of men.”810 The Philippines therefore submits
that, “provided it has been exercised over a long period of time without interruption or
opposition,” traditional fishing in the territorial sea of another State is protected by generalinternational law as incorporated through Article 2(3) of the Convention.811 In this regard, thePhilippines notes that, in the Abyei Arbitration, the tribunal “applied the same rule even to thedelimitation of a land boundary to protect traditional grazing rights.”812
778. With regard to the scope of traditional fishing rights protected, the Philippines again refers to
the Eritrea v. Yemen award. The Philippines accordingly argues that a State may restrict fishingrights “only . . . to the extent those activities may go beyond those that have traditionally been
conducted.”813 Within the sphere of protected fishing rights, however, the Philippines considers
that “any other administrative measure that might impact” traditional fishing rights “must be
agreed between the states involved.”814
779. The Philippines argues that fishing by Philippine nationals at Scarborough Shoal “plainly
meets” the threshold required to deem it a protected activity under international law. 815 It
characterises Filipino fishing practices in the area as “longstanding”, 816 “long”, 817 “deep”, 818“peaceful”, 819 “uninterrupted”, 820 “ancient”, 821 andhaving occurred “since times

immemorial”.822 In the Philippines’ view, a combination of sources, ranging from (a) colonial

describing fishing practices there,824 and (c) testimony of Filipino fishermen,825 all support theconclusion that the fishing practices it alleges qualify as activities protected under Article 2(3)of the Convention.
780. In the Philippines’ view, China has additionally breached its obligations under Article 2(3) of
the UN Charter and Article 279 of the Convention to resolve disputes through peacefulmeans.826 It suggests that China “rejected” a Philippine proposal to settle the Parties’ dispute
through recourse to the International Tribunal for the Law of the Sea;827 instead, the Philippines
argues, China “sought to consolidate its hold on Scarborough Shoal by deploying and anchoring
Chinese vessels in such manner as to form an effective physical barrier to prevent Philippine
vessels from entering the area.”828 The Philippines adds:
Despite the longstanding use of Scarborough Shoal as a traditional fishing ground by
Filipino fishermen, China abruptly acted to prevent them from pursuing their livelihoods inthe area in April and May 2012. . . . China has since that date exercised control over
Scarborough and only intermittently allowed Filipino fishing vessels to approach the area.
These acts violate China’s obligations under the Convention. 829

781. Finally, the Philippines seeks to distinguish its Submissions regarding “historic fishing rights”
from “historic rights” as claimed by China. It does so in three ways. First, whereas China
allegedly asserts “rights of control”, including over “exploration for and exploitation of all the
resources within the nine-dash line,” the Philippines maintains that it “seeks only access for its
fishermen to pursue their traditional livelihood.”830 Second, the Philippines claims that “there isan obvious and significant difference between individual, non-exclusive rights on the one
hand,” such as those for which it purports to seek protection in this arbitration, and “exclusive
sovereign rights on the other,” including China’s claim to “exclusive sovereign rights to all the
resources in areas beyond 12 miles from Scarborough [Shoal].” 831 Third, the Philippines
contends that its Submission No. 10 is “limited to the territorial sea”—the regime of which iscircumscribed by “other rules of international law” per Article 2(3)— as compared with China's

assertion of “exclusive historic rights . . . beyond the limits of any conceivable entitlement
under the Convention.”832(b)Articles 51(1) and 62(3) of the Convention

782. The Philippines considers that Articles 51(1) and 62(3) of the Convention, though not directly
applicable to the present case, are nevertheless relevant insofar as they refer to traditional
fishing rights. 833 Article 51(1) provides that “an archipelagic State . . . shall recognize
traditional fishing rights and other legitimate activities of the immediately adjacentneighbouring States in certain areas falling within archipelagic waters.”

For its part,

Article 62(3) provides that, “[i]n giving access to other States to its exclusive economic zone
under this article, the coastal State shall take into account all relevant factors, including, interalia, . . . the need to minimize economic dislocation in States whose nationals have habitually
fished in the zone.”783. In the Philippines’ view, Articles 51(1) and 62(3) are important for two reasons. First, they
constitute an “express recognition of the existence, and underscore[] the importance, oftraditional fishing by the nationals of the immediately adjacent coastal states.”834 Second, thearticles confirm that, where the drafters of the Convention intended to “preserve traditional
fishing in the context of the new legal regimes they created,” they did so “explicitly” and “madeclear to what extent such prior uses were or were not protected.”835(c)China’s Obligation to Act in Good Faith and Settle Disputes by Peaceful Means

784. Finally, the Philippines submits that China has “unlawfully endangered justice by exacerbating
the dispute between it and the Philippines concerning their maritime rights and entitlements inthe vicinity of Scarborough Shoal.”836 Specifically, the Philippines considers China’s conduct
to be in breach of its obligations, both under Articles 279 and 300 of the Convention and undergeneral international law, to refrain from “any acts that might aggravate or extend thedispute.”837 The Philippines’ arguments in relation to these issues are elaborated more fully inparagraphs 1130 to 1140 of this Award, relating to its Submission No. 14.

785. In relation to the present Submission, the Philippines observes that China took no actions to
disturb traditional fishing by Filipinos in the aftermath of declaring a territorial sea of
12 nautical miles around Scarborough Shoal in 1958.838 It concludes that, in light of “China’s
own longstanding practice in what it claims as territorial sea,” China has “create[d] an
obligation not to endanger justice by abruptly altering the status quo on which local artisanal
fishing depends.”839
4.

China’s Position

786. Although China has not responded to the Philippines’ Submission in the context of theseproceedings, China’s position is made clear in its contemporaneous statements from 2012.
787. Like the Philippines, China claims sovereignty over Scarborough Shoal and asserts that its
waters constitute a traditional fishing ground for Chinese fishermen. On 12 June 2012, theEmbassy of China in Manila published the following statement laying out China’s claim:
Huangyan Island and its surrounding waters have been China’s traditional fishing grounds
since ancient times. Chinese fishermen have engaged in fishery activities for generations.
In addition, they have used Huangyan Island as a safe have in their voyage in the South
China Sea. Genglubu, an ancient Chinese navigation log recording trips in the South China
Sea, and other ancient documents and literature contain complete records of Chinese
fishermen’s activities around Huangyan Island. Since the Yuan Dynasty, the Chinese
people have never stopped developing and exploiting Huangyan Island and its surrounding
waters and the Chinese government has exercised effective management and jurisdiction
over their activities all these years. These historical facts are supported by official
documents, local chronicles and official maps in the past centuries. 840

788. China also set out its own account of the events that took place on 10 April 2012:
When 12 fishing boats from Hainan, China were conducting normal operations in the
Huangyan Island lagoon on the morning of April 10, the Philippine Navy warship Gregoriodel Pilar blocked the entrance to the lagoon. The Philippine armed personnel boarded four
Chinese fishing boats, question the Chinese fishermen, searched the boats and took photos.
They were rude and rough, severely violated China’s territorial sovereignty and the humanrights of Chinese fishermen. On the afternoon of 10 April, upon learning of the incident,
the Chinese marine surveillance vessels No.84 and No.75, both performing routine patrol
duty nearby, immediately headed to the Island to protect the safety of the Chinese
fishermen. On the afternoon of 11 April, the Chinese fishery administration boat No.303
also arrived on the site and instructed the Chinese fishing boats and fishermen to evacuatesafely and get rid of the Philippine intimidation. Afterwards, an archaeological ship of thePhilippines stayed in the lagoon for illegal operation for a long time, and refused to leave
the site until 18 April after China’s repeated representations. 841

789. China also elaborated on its actions following April 2012:
After the occurrence of Huangyan Island Incident, China has consistently adhered to its
position of solving the issue through diplomatic consultation. However, the Philippines
kept escalating the situation, made erroneous remarks to mislead the public at home andabroad and whip up hostile sentiments. All the above actions have severely damaged thebilateral relations. To prevent further provocations by the Philippines, the Chinese public
service ships have continued to keep close watch over Huangyan Island waters, provide
administrative and other service to Chinese fishing boats in accordance with China’s laws,
so as to ensure Chinese fishermen a good environment for operations in their traditional
fishing grounds.842

790. China has also responded to the Philippines’ allegations that China’s conduct fell short of its
obligation to resolve the Parties’ dispute peacefully. On 24 May 2012, the Chargé d’Affaires of
the Philippines’ Embassy in Beijing met with the Director General of the Department ofBoundary and Ocean Affairs of China’s Ministry of Foreign Affairs. As recorded by thePhilippines, China expressed the following position:
DG Deng also referred to Article 2.4 of the United Nations Charter, saying that on 10 April,
the Philippines used a warship to harass unarmed Chinese fishermen. This is a sign of theuse of force. Since April 10, all actions of the Philippines in Huangyan Island are inviolation of Chinese territorial sovereignty. The Philippines is now citing Article 2.4.
China believes that it is the Philippines that has violated this Article and China deeply
regrets this.
...
There have been no Chinese words or actions to escalate the situation at the multilaterallevel; on the diplomatic front or in the media. Nor has China taken any action on the
ground in Huangyan Island waters.843

791. As far as the Tribunal is aware, China has not made specific statements concerning the status ofFilipino fishermen at Scarborough Shoal. Nevertheless, the Tribunal considers the content ofChina’s statements, especially with regard to the presence and conduct of Chinese vessels at thefeature, to indicate China’s position that its actions at Scarborough Shoal are generally lawful.
5.

The Tribunal’s Considerations

792. The Tribunal notes at the outset that both the Philippines and China claim sovereignty over
Scarborough Shoal and that both the Philippines and China consider Scarborough Shoal to be a
traditional fishing ground for their nationals.
793. Consistent with the limitations on its jurisdiction, the Tribunal has refrained from any decisionor comment on sovereignty over Scarborough Shoal. The Tribunal also considers it imperative

to emphasise that the following discussion of fishing rights at Scarborough Shoal is notpredicated on any assumption that one Party or the other is sovereign over the feature. Nor isthere any need for such assumptions. The international law relevant to traditional fishing would
apply equally to fishing by Chinese fishermen in the event that the Philippines were sovereignover Scarborough Shoal as to fishing by Filipino fishermen in the event that China weresovereign. The Tribunal’s conclusions with respect to traditional fishing are thus independentof the question of sovereignty.
(a)

The Law Applicable to Traditional Fishing

794. The attention paid to traditional fishing rights in international law stems from the recognition
that traditional livelihoods and cultural patterns are fragile in the face of development andmodern ideas of interstate relations and warrant particular protection.
795. Also referred to as artisanal fishing, traditional fishing was extensively discussed in the Eritrea
v. Yemen arbitration, which looked to the reports of the Food and Agriculture Organization of
the United Nations (the “FAO”) for guidance on artisanal fishing in the Red Sea. Relying on
the FAO’s studies of artisanal fishing, that tribunal noted that:
artisanal vessels and their gear are simple. The vessels are usually canoes fitted with small
outboard engines, slightly larger vessels (9-12m) fitted with 40-75 hp engines, or fishingsambuks with inboard engines. Dugout canoes and small rafts (ramas) are also in use.
Hand lines, gill nets and long lines are used. In its Report on Fishing in Eritrean waters, the
FAO study states that this artisanal fishing gear, which varies according to the boat and thefish, is “simple and efficient”. 844

796. The Eritrea v. Yemen tribunal went on, however, to note:the term “artisanal” is not to be understood as applying in the future only to a certain typeof fishing exactly as it is practised today. “Artisanal fishing” is used in contrast to“industrial fishing”. It does not exclude improvements in powering the small boats, in thetechniques of navigation, communication or in the techniques of fishing; but the traditional
regime of fishing does not extend to large-scale commercial or industrial fishing nor tofishing by nationals of third States in the Red Sea, whether small-scale or industrial.845

797. Artisanal fishing has been a matter of concern in a variety of international fora without any
common definition having been adopted. Artisanal fishing has been addressed at the World
Trade Organization in the context of the Doha Round negotiations on fisheries subsidies, 846

where a variety of definitions have been advanced.847 Traditional, artisanal, and small-scale
fishing has also formed part of the work of the FAO,848 the International Labour Office,849 andthe United Nations Environment Programme (“UNEP”).850 Despite this attention, the essential
defining element of artisanal fishing remains, as the tribunal in Eritrea v. Yemen noted, relative.
The specific practice of artisanal fishing will vary from region to region, in keeping with local
customs. Its distinguishing characteristic will always be that, in contrast with industrial fishing,artisanal fishing will be simple and carried out on a small scale, using fishing methods thatlargely approximate those that have historically been used in the region.
798. The legal basis for protecting artisanal fishing stems from the notion of vested rights and theunderstanding that, having pursued a livelihood through artisanal fishing over an extended
period, generations of fishermen have acquired a right, akin to property, in the ability tocontinue to fish in the manner of their forebears. Thus, traditional fishing rights extend toartisanal fishing that is carried out largely in keeping with the longstanding practice of thecommunity, in other words to “those entitlements that all fishermen have exercised continuously
through the ages,”851 but not to industrial fishing that departs radically from traditional practices.
Importantly, artisanal fishing rights attach to the individuals and communities that havetraditionally fished in an area. These are not the historic rights of States, as in the case ofhistoric titles, but private rights, as was recognised in Eritrea v. Yemen, where the tribunal
declined to endorse “the western legal fiction . . . whereby all legal rights, even those in reality
held by individuals, were deemed to be those of the State.”852
799. Where private rights are concerned, international law has long recognised that developmentswith respect to international boundaries and conceptions of sovereignty should, as much as
possible, refrain from modifying individual rights. Thus the Permanent Court of International
Justice in its Settlers of German Origin in Poland advisory opinion noted that “[p]rivate rights

Award of 12 July 2016acquired under existing law do not cease on a change of sovereignty,”853 and the tribunal in the
Abyei Arbitration observed that “traditional rights, in the absence of an explicit agreement to thecontrary, have usually been deemed to remain unaffected by any territorial delimitation.”854 The
same principle was recognised with respect to rights at sea by the tribunal in the Bering Sea
Arbitration, when it exempted indigenous peoples from its division of jurisdiction with respect
to the hunting of fur seals in the Bering Sea.855
800. Before turning to the question of the status of artisanal fishing rights under the Convention, theTribunal notes that it is conscious of what could be seen as a contradiction in the Philippines’
Submissions. On the one hand, the Philippines has asserted (and the Tribunal has agreed) thatany historic rights China may have had in the waters of the South China Sea beyond its
territorial sea were extinguished by the adoption in the Convention and in customary law of theconcept of the exclusive economic zone. On the other hand, the Philippines has argued that its
traditional fishing rights at Scarborough Shoal must be protected, even in the event that China
has sovereignty over the feature.
801. The Tribunal considers that no contradiction in fact exists between these two positions. Rather,
the law reflects the particular circumstances of the creation of the exclusive economic zone.
802. Under the law existing prior to the exclusive economic zone, any expansion of the maritime
areas under national jurisdiction functioned essentially as described in paragraph 799 above.
The expansion of jurisdiction was considered equivalent to the adjustment of a boundary or achange in sovereignty, and acquired rights, in particular to fisheries, were considered protected.
Thus, in the Fisheries Jurisdiction Cases, the International Court of Justice held that Iceland’s
expansion of its fisheries zone could give it only preferential rights vis-à-vis the nationals ofStates that had habitually fished in the area.856
803. With the adoption in the Convention of the exclusive economic zone, however, a different
calculus applied. Having reviewed the extensive attention given to the question of fishing by
nationals of other States in the exclusive economic zone (see paragraphs 248 to 254 and 522

to 538 above) and the degree of control over fisheries that was ultimately given to the coastal
State, the Tribunal does not consider it possible that the drafters of the Convention intended for
traditional or artisanal fishing rights to survive the introduction of the exclusive economic zone.
In this respect, the Tribunal disagrees with the conclusions of the tribunal in Eritrea v. Yemen(which held that the traditional fishing regime in the Red Sea extended throughout the maritime
zones of those States) and considers that that tribunal was able to reach the conclusions it did
only because it was permitted to apply factors other than the Convention itself under theapplicable law provisions of the parties’ arbitration agreement (see paragraph 259 above).
804. Under the Convention, therefore, traditional fishing rights are accorded differing treatment
across maritime zones:(a)

In archipelagic waters, traditional fishing rights are expressly protected, and Article 51(1)of the Convention provides that “an archipelagic State shall respect existing agreementswith other States and shall recognize traditional fishing rights and other legitimate
activities of the immediately adjacent neighbouring States in certain areas falling withinarchipelagic waters.”(b)

In the exclusive economic zone, in contrast, traditional fishing rights are extinguished,
except insofar as Article 62(3) specifies that “the need to minimize economic dislocationin States whose nationals have habitually fished in the zone” shall constitute one of thefactors to be taken into account by the costal State in giving access to any surplus in theallowable catch. The Tribunal considers that the inclusion of this provision—which
would be entirely unnecessary if traditional fishing rights were preserved in the exclusive
economic zone—confirms that the drafters of the Convention did not intend to preserve
such rights. The Convention does not, of course, preclude that States may continue torecognise traditional fishing rights in the exclusive economic zone in their legislation, inbilateral fisheries access agreements, or through regional fisheries management
organisations. Such recognition would, in most instances, be commendable, but it is not
required by the Convention, except to the extent specified in Article 62(3).

(c)

Finally, in the territorial sea, the Convention continued the existing legal regime largely
without change. The innovation in the Convention was the adoption of an agreed limit of
12 nautical miles on the breadth of the territorial sea, not the development of its legal
content.

The Tribunal sees nothing that would suggest that the adoption of theConvention was intended to alter acquired rights in the territorial sea and concludes thatwithin that zone—in contrast to the exclusive economic zone—established traditional

314

fishing rights remain protected by international law. The Tribunal also notes that the vast
majority of traditional fishing takes place in close proximity to the coast.
(b)

The Protection of Traditional Fishing at Scarborough Shoal

805. Based on the record before it, the Tribunal is of the view that Scarborough Shoal has been a
traditional fishing ground for fishermen of many nationalities, including the Philippines, China(including from Taiwan), and Viet Nam. The stories of most of those who have fished at
Scarborough Shoal in generations past have not been the subject of written records, and the
Tribunal considers that traditional fishing rights constitute an area where matters of evidence
should be approached with sensitivity. That certain livelihoods have not been considered ofinterest to official record keepers or to the writers of history does not make them less importantto those who practise them. With respect to Scarborough Shoal, the Tribunal accepts that theclaims of both the Philippines and China to have traditionally fished at the shoal are accurate
and advanced in good faith.
806. The Tribunal does not have before it extensive details of the fishing methods traditionally usedby either Filipino or Chinese fishermen, or of the communities that have traditionally dispatchedvessels to Scarborough Shoal. In keeping with the fact that traditional fishing rights arecustomary rights, acquired through long usage, the Tribunal notes that the methods of fishingprotected under international law would be those that broadly follow the manner of fishing
carried out for generations: in other words, artisanal fishing in keeping with the traditions andcustoms of the region. The Tribunal is not prepared to specify any precise threshold for thefishing methods that would qualify as artisanal fishing, nor does the Tribunal deem it necessary
to consider how and when traditional fishing practices may gradually change with the advent oftechnology.
807. Based on the record before it,857 the Tribunal is of the view that at least some of the fishing
carried out at Scarborough Shoal has been of a traditional, artisanal nature. The Tribunal is also
open to the possibility that some of the fishing at Scarborough Shoal may have become
sufficiently organised and industrial in character that it can no longer fairly be consideredartisanal.

315

The South China Sea Arbitration

808. Turning to the Philippines’ Submission, the Tribunal notes that Article 2(3) of the Convention
provides that “[t]he sovereignty over the territorial sea is exercised subject to this Convention
and to other rules of international law.” The Tribunal agrees with the finding in the Chagos
Marine Protected Area Arbitration that, in the territorial sea, “Article 2(3) contains an
obligation on States to exercise their sovereignty subject to ‘other rules of international law’.”858
Traditional fishing rights constitute a vested right, and the Tribunal considers the rules ofinternational law on the treatment of the vested rights of foreign nationals859 to fall squarely
within the “other rules of international law” applicable in the territorial sea.
809. The Tribunal notes, however, that traditional fishing rights are not absolute or impervious toregulation.

Indeed, the careful regulation of traditional fishing may be necessary forconservation and to restrict environmentally harmful practices. Customary international law, in
this respect, does not restrict the coastal State from reasonable regulation (a principle recognisedwith respect to treaty-based fishing rights in North Atlantic Coast Fisheries860). Nor would it
prevent the coastal State from assessing the scope of traditional fishing to determine, in goodfaith, the threshold of scale and technological development beyond which it would no longer
accept that fishing by foreign nationals is traditional in nature.
810. The Tribunal finds as a matter of fact that since May 2012, Chinese Government vessels haveacted to prevent entirely fishing by Filipino fishermen at Scarborough Shoal for significant, but
not continuous, periods of time. The Philippines has provided evidence of Chinese vessels
physically blockading the entrance to Scarborough Shoal, 861 and Filipino fishermen havetestified to being driven away by Chinese vessels employing water cannon. 862 During these
periods, Chinese fishing vessels have continued to fish at Scarborough Shoal.863 The actions ofChinese Government vessels constitute official acts of China, and the consequences that follow
from them are attributable to China as such.
811. With respect to these actions, the Tribunal considers that the Philippines’ Submission No. 10 isbased on one of two alternative premises. If, on the one hand, the Philippines is sovereign over858

Scarborough Shoal, then the surrounding waters would constitute the territorial sea of thePhilippines, with all that follows from it. If, on the other hand, China is sovereign over
Scarborough Shoal, the premise of the Philippines’ Submission is that China has failed torespect the traditional fishing rights of Filipino fishermen within China’s territorial sea.
812. In the Tribunal’s view, it is not necessary to explore the limits on the protection due incustomary international law to the acquired rights of individuals and communities engaged in
traditional fishing. The Tribunal is satisfied that the complete prevention by China of fishing by
Filipinos at Scarborough Shoal over significant periods of time after May 2012 is notcompatible with the respect due under international law to the traditional fishing rights ofFilipino fishermen. This is particularly the case given that China appears to have acted toprevent fishing by Filipinos, specifically, while permitting its own nationals to continue. The
Tribunal is cognisant that April and May 2012 represented a period of heightened tensions
between the Philippines and China at Scarborough Shoal. China’s dispute with the Philippines
over sovereignty and law enforcement at Scarborough Shoal, however, was with the Philippine
Government. The Tribunal does not see corresponding circumstances that would have justified
taking action against Filipino fishermen engaged in their traditional livelihood or that would
have warranted continuing to exclude Filipino fishermen from Scarborough Shoal for months
after the Philippines had withdrawn its official vessels. The Tribunal notes, however, that it
would have reached exactly the same conclusion had the Philippines established control over
Scarborough Shoal and acted in a discriminatory manner to exclude Chinese fishermen engaged
in traditional fishing.
813. With respect to the Philippines’ claim that China’s actions at Scarborough Shoal represented a
specific failure to fulfil its duties pursuant to Article 2(3) of the UN Charter and Article 279 of
the Convention to settle disputes by peaceful means, the Tribunal notes that both Parties found
fault with the other in their handling of the standoff and that both found cause to allege breachesof the UN Charter.864 The Tribunal does not find the record before it sufficient to support such aclaim in respect of either Party.

The South China Sea Arbitration
Award of 12 July 2016(c)Conclusion

814. Based on the considerations outlined above, the Tribunal finds that China has, through theoperation of its official vessels at Scarborough Shoal from May 2012 onwards, unlawfully
prevented Filipino fishermen from engaging in traditional fishing at Scarborough Shoal. The
Tribunal records that this decision is entirely without prejudice to the question of sovereignty
over Scarborough Shoal.

ALLEGED FAILURE TO PROTECT AND PRESERVE THE MARINE ENVIRONMENT(SUBMISSIONS NO. 11 AND 12(B))
1.

Introduction

815. This Section addresses the Parties’ dispute concerning the protection and preservation of themarine environment. This dispute is reflected in the Philippines’ Submission No. 11, which
provides (as amended):(11)

China has violated its obligations under the Convention to protect and preserve themarine environment at Scarborough Shoal, Second Thomas Shoal, Cuarteron Reef,
Fiery Cross Reef, Gaven Reef, Johnson Reef, Hughes Reef and Subi Reef;

816. This dispute is also reflected in the portion of the Philippines’ Submission No. 12 concerning
environmental harm from China’s construction at Mischief Reef:(12)

China’s occupation of and construction activities on Mischief Reef(b)violate China’s duties to protect and preserve the marine environment under
the Convention; . . .

817. The Philippines’ allegations concerning China’s environmental violations relate to two generalcategories of conduct: harmful fishing practices and harmful construction activities.
818. Prior to 30 November 2015, the Philippines’ Submission No. 11 had been limited to “the marine
environment at Scarborough Shoal and Second Thomas Shoal.”865 The Philippines’ Memorial
focused on environmentally harmful fishing practices at those two features undertaken by
Chinese fishing vessels, allegedly with the toleration and active support of China. 866 The
activities complained of included the use of cyanide and explosives and the harvesting ofendangered giant clams and sea turtles. The Philippines also introduced evidence of land
reclamation and construction by China on a number of features in the Spratly Islands.867 The
Philippines argued, in the context of its Submission No. 12(b) concerning Mischief Reef, that
China’s construction of artificial islands, installations, and structures had breached its
obligations to protect and preserve the marine environment. In support of these allegations, thePhilippines filed an expert report by reef ecologist Professor Kent E. Carpenter of Old
Dominion University in Norfolk, Virginia, United States (the “First Carpenter Report”).

819. Subsequent to filing its Memorial, the Philippines periodically expressed to the Tribunal its“deep concerns” about China’s “extensive land reclamation” and construction activities atseveral features in the Spratly Islands and their impact on the “fragile marine environment in thevicinity of these sites”868 in disregard of China’s duty not to cause serious harm to the marine
environment.”869 Shortly before the Hearing on the Merits, the Tribunal granted leave to thePhilippines to enter into the record new aerial and satellite photography showing China’s
construction activities in the South China Sea and a second report by Professor Carpenter,co-authored with Dr. Loke Ming Chou of the National University of Singapore, entitled“Environmental Consequences of Land Reclamation Activities on Various Reefs in the South
China Sea” (the “Second Carpenter Report”).
820. During the Hearing on the Merits, the Philippines requested the Tribunal’s permission to amend
Submission No. 11 so that it would also cover the marine environment at Cuarteron Reef,
Fiery Cross Reef, Johnson Reef, Hughes Reef, Gaven Reef and Subi Reef.870 The Philippines
noted that evidence relevant to those features had not been available at the time of drafting theMemorial. The Philippines specified that China’s artificial island-building activities at thesefeatures breached Articles 123, 192, 194, 197, 205, and 206 of the Convention.871 The Tribunal
granted the Philippines leave to amend its Submissions, noting that the proposed amendment
was related to or incidental to the Philippines’ original Submissions (which included theenvironmental effects of island building at Mischief Reef) and did not involve the introductionof a new dispute between the Parties.872
821. After seeking the views of the Parties, the Tribunal sought an independent opinion on theenvironmental impact of China’s construction activities. Pursuant to Article 24 of the Rules ofProcedure, the Tribunal appointed Dr. Sebastian C.A. Ferse of the Leibniz Center for TropicalMarine Ecology in Bremen, Germany. Dr. Ferse is a coral reef ecologist with over ten years’
research experience in Southeast Asia, the Pacific Islands, East Africa, and the Red Sea. His
ecological work has focused on coral reef restoration and ecological functioning and the impact
of environmental and anthropogenic factors on coral reef benthic communities. Additionally,
the Tribunal appointed Dr. Peter J. Mumby, a Professor of coral reef ecology at the School of

research into the responses of corals to environmental stress including elevated nutrients,
mechanical damage and elements of climate change. On 26 April 2016, Dr. Ferse, Professor
Mumby, and Dr. Ward provided their “Assessment of the Potential Environmental
Consequences of Construction Activities on Seven Reefs in the Spratly Islands in the South China
Sea.”873 The report is based on an independent review of the factual record, scientific literature,and other publicly available documents, including from China.
822. As discussed further in paragraphs 925 to 938 below, the Tribunal in its Award on Jurisdiction
found that it has jurisdiction over Submission No. 11, as involving a dispute over theinterpretation and application of Articles 192 and 194 of the Convention (imposing obligations
on States to protect and preserve the marine environment).874 The Tribunal deferred its decision
on jurisdiction over all of Submission No. 12 for further consideration in connection with themerits.875

Factual Background(a)

The Marine Environment of the South China Sea

823. The South China Sea includes highly productive fisheries and extensive coral reef ecosystems,
which are among the most biodiverse in the world. 876 The marine environment around
Scarborough Shoal and the Spratly Islands has an extremely high level of biodiversity of
species, including fishes, corals, echinoderms, mangroves, seagrasses, giant clams, and marine
turtles, some of which are recognised as vulnerable or endangered.877

Award of 12 July 2016824. While coral reefs are amongst the most biodiverse and socioeconomically important
ecosystems, they are also fragile and degrade under human pressures.878 Threats to coral reefs
include overfishing, destructive fishing, pollution, human habitation, and construction.879
825. In the South China Sea, ocean currents and the life cycles of marine species create a high degreeof connectivity between the different ecosystems. 880 This means that the impact of any
environmental harm occurring at Scarborough Shoal and in the Spratly Islands may not belimited to the immediate area, but can affect the health and viability of ecosystems elsewhere in
the South China Sea.881(b)Harmful Fishing Practices and Harvesting of Endangered Species

826. Documents adduced by the Philippines record a number of instances since the late 1990s inwhich Chinese fishing vessels have engaged in environmentally harmful fishing practices andthe harvesting of endangered or threatened species. The same documents indicate that Chinese
Government vessels have been present on some, but not all, of these occasions. The following
is an overview of this record.
i.

Incidents at Scarborough Shoal in the Period from 1998 to 2006

827. The earliest incidents detailed by the Philippines date from January 1998 when, according topolice reports, 22 Chinese fishermen were involved in harvesting corals and marine turtles in
the waters of Scarborough Shoal. 882 In March 1998, 29 Chinese fishermen at ScarboroughIUCN Red List of Threatened Species (Annex 724); S. Wells, IUCN, “Tridacna maxima,” IUCN Red Listof Threatened Species (Annex 725); S. Wells, IUCN, “Tridacna squamosa,” IUCN Red List of Threatened

Shoal were reported to be found in possession of dynamite and corals. 883 Several of thefishermen were prosecuted and convicted under Philippine fisheries laws.884
828. Further incidents of unlawful harvesting of coral were reported in a Note Verbale dated
14 January 2000, in which the Philippines asked China to take “resolute action” against
fishermen found with corals at Scarborough Shoal, and expressed concern that:
This illegal activity disturbed the tranquility of the ecosystem and habitat of important
species of marine life and, at the same time, caused irreparable damage to the marine
environment of the area. It might be noted that the gathering and trade of corals violate theprovisions of three (3) international conventions to which China is a signatory, namely, theConvention on Biological Diversity which entered into force on 29 December 1993; the
RAMSAR Convention adopted in Iran in 1971, and the Convention on International Tradein Endangered Species of Wild Fauna and Flora (CITES) which entered into force on 01
July 1975.885

829. In April 2000, three Chinese fishing vessels were found at Scarborough Shoal by Philippine
authorities, loaded with corals, cyanide, blasting caps, detonating cord, and dynamite.886
830. On 29 January 2001, Philippine authorities photographed and confiscated the catch ofendangered “sharks, eels, turtles and corals” from four Chinese fishing vessels in the vicinity of
Scarborough Shoal.887 The incident led to diplomatic exchanges in which China asserted its
sovereignty over Scarborough Shoal and noted that “the Chinese Government attaches great

confiscated “endangered marine resources (giant oysters), cyanide and blasting caps” from
Chinese fishing vessels.889
831. On at least three occasions in 2002, the Philippine Navy confiscated explosives, cyanide, corals,
sea shells, and sea clams from Chinese fishing vessels at Scarborough Shoal.890
832. On 31 October 2004, Philippine naval vessels again intercepted Chinese fishing vessels at
Scarborough Shoal laden with giant clams.891
833. On 30 December 2005, during a “routine inspection” at Scarborough Shoal, the Philippine
vessel BRP Artemio Ricarte found four Chinese fishing vessels in possession of “assorted
corals, live clamshells weighing about 16 tons and illegal fishing gears.” 892 The catch wasphotographed and confiscated and the crew then released. The incident led the Chinese Vice
Foreign Minister to summon the Philippine Ambassador in Beijing to convey China’s “grave
concern and strong opposition” and reiterate China’s position that it has “indisputable
sovereignty over Scarborough Shoal and adjacent waters.”893 The Philippines in turn expressed“grave concern” about the “harmful illegal fishing and rampant trading of endangered corals

ii.

Incidents at Scarborough Shoal in April 2012

835. On 10 April 2012, the Philippine naval vessel BRP Gregoria del Pilar, and smaller boats
launched from it, conducted a “Visit, Board, Search and Seizure Operation” on Chinese fishingvessels inside Scarborough Shoal and reported finding “large amounts of corals and giant
clams” inside the first Chinese vessel boarded.896 A further eight Chinese vessels were boarded
throughout the morning, resulting in the documentation and recovery of “assorted endangered
species” including “corals and giant clams.”897 Later that afternoon, two CMS vessels moved
towards the shoal, “placing themselves between” BRP Gregoria del Pilar and the eight Chinese
fishing boats.898
836. The incident of 10 April 2012 led to what the Philippine Navy described as a “diplomaticstand-off . . . following the discovery of Chinese fishing vessels . . . harvesting corals andcapturing endangered marine species and the subsequent interference by Chinese maritime law
enforcement vessels.”899 During the remainder of April 2012, the Philippine Navy and Coast

Relevant Chinese authorities have dispatched administrative vessels rather than military
vessels to the Huangyan Island waters to protect the safety and legitimate fishing activities
of Chinese fishermen and fishing vessels. 901

838. On 23 April 2012, the Philippine Coast Guard observed two Chinese fishing vessels with stacks
of giant clams inside the cargo hold, as well as several Chinese utility boats “dragging
something underwater that caused seawater discoloration.”902
839. On 26 April 2012, the Philippine Coast Guard reported to the Bureau of Fisheries that it had
seen a Chinese fishing boat depart Scarborough Shoal “loaded with giant clams and othermarine products” but noted that “[a]ll we can do is observe[], we cannot apprehend the poachers
because they are being protected by two China Marine Surveillance ships.”903
840. On 2 May 2012, Philippine Bureau of Fisheries personnel described how, during April 2012,
Chinese CMS and FLEC vessels were docking alongside and protecting Chinese fishing vessels
in Scarborough Shoal while they undertook trawling, fishing, dredging, and towing.904
841. The Philippines expressed its concerns to ASEAN Member States on 21 May 2012, about theissue of “Chinese fishermen poaching in the area” noting that “although these fishermen havealready evaded arrests and prosecution for illegal fishing, nevertheless, Chinese Government
vessels continue to ply the area in [] much larger numbers now.” 905 Simultaneously, thePhilippines sent a Note Verbale to the Chinese Embassy in Manila stating that:the increase in the number of China’s vessels in the area imperils the marine diversity in the
Shoal and threatens the marine ecosystem in the whole West Philippine Sea. The
Philippines has documented the many instances where Chinese fishermen have unlawfully
dredged the area and illegally harvested giant clams and corals.906

842. In response, China recalled that after the incident of 10 April 2012, it had urged the Philippines
to withdraw all Philippine ships immediately, and once again urged that the Philippines

fishing boats and law enforcement activities by China’s public service ships.”907
843. By 2 June 2012, an air reconnaissance mission undertaken by the Philippine Navy reported
there were 28 “Chinese fishing vessels trawling alongside each other” at Scarborough Shoal,
with flotation devices “believed intended to obstruct the passage to the shoal” and four Chinese
FLEC vessels and five CMS ships were sighted in the area.908
844. The Philippines has refrained from sending any further vessels to Scarborough Shoal since
May 2012 and accordingly its recent monitoring of poaching activities has been limited.909

More Recent Incidents in Other Parts of the South China Sea

845. According to reports of the Armed Forces of the Philippines, two fishing vessels “believed to be
Chinese were monitored fishing using explosives and sodium cyanide 4 NM SW off LT57” inSecond Thomas Shoal on 12 February 2012.910
846. A situation report on Second Thomas Shoal prepared by the Armed Forces of the Philippines on
11 May 2013 contains a photograph depicting a Chinese vessel laden with giant clams andcorals.911 A few days later, the Armed Forces of the Philippines also reported sighting various
Chinese Government vessels such as “Jianghu V Missile Frigate 562” and China Marine
Service vessels, CMS 84 and CMS 167, alongside two Hainan fishing vessels with threedinghies “believed to be gathering corals and clams and dredging in the shoal.”912

The South China Sea Arbitration
Award of 12 July 2016evidence already in the record,914 on 18 December 2015, the Philippines submitted a new BBC
article and video footage reporting that “[a]t least a dozen boats” trailing “plumes of sand andgravel” near Thitu were engaged in harvesting endangered species including hundreds of giant
clams.915 The BBC showed the fishermen’s method, of breaking up coral with their propellers
and described the resultant “complete devastation” of the reefs.916
848. The Tribunal-appointed expert, Dr. Ferse, also drew the Tribunal’s attention to recent reportingon the damaging use of propellers to break up coral and release giant clams for ultimate sale on
lucrative curio markets. One report states “widespread chopping of reefs by fishermen using
propellers mounted on small boats in order to poach giant clam shells is visible on recent
images of at least 28 reefs in the Spratly and Parcel island groups” and refers to “abundantevidence that China’s navy and coast guard have been aware of the Tanmen fishermen’s
practice of chopping reefs, and tolerated or condoned it.”917
849. Noting such reports, the Tribunal conveyed a request from Dr. Ferse to seek clarification from ascientist, Professor John McManus of the University of Miami, United States, whose studies
had been cited during the Hearing on the Merits.918 Specifically, the Philippines was invited tofind out “what proportion of Professor McManus’ estimates on the extent of reef area damaged
he would confidently assign to dredging versus clam shell extraction.”919
850. As a result of this process, Professor McManus provided the Tribunal with a revised version of
his unpublished paper920 and reported that he had conducted further examinations, interviews,
studies of satellite imagery, and an underwater inspection at clam extraction sites near Thitu. Hestated:I confirmed both that the affected areas were very shallow (generally 1-3 m deep) and thatthe presence of masses of dead broken branching coral, as well as abundant sand on one of
the reefs, ruled out dredging as a cause. The thoroughness of the damage to marine life

exceeded anything I had previously seen in four decades of investigating coral reef
degradation. Interviews with local fishers, officials and military personnel indicated that
this highly destructive PRC harvesting practice was now very widespread across the Spratly
area.
...
The new results indicate that the People’s Republic of China (PRC) is responsible for atleast 39 km2 of damage from shallow dredging and 69 km2 of damage from giant clam
harvest using propellers to dig up the bottom within the Greater Spratly Islands . . . .
Vietnam is responsible for shallow dredging covering approximately 0.26 km2. The overall
damage to coral reefs within the Greater Spratly Islands covers at least 124 km 2, of which
PRC is responsible for 99%.921

851. The Philippines also filed a short additional report from Professor Carpenter commenting on the
new material from Professor McManus. Professor Carpenter stated the “extraction methods
employed by Chinese fishermen, which are countenanced by the Chinese Government, areextremely destructive to reef habitat and represent unprecedented harm to the marine
environment.” 922 He recalled having already addressed the environmental impact of giant clam
extraction,923 but at the time he had prepared his reports he had “not appreciated the scale uponwhich this is occurring.” 924 The Tribunal’s experts also observe from satellite imagery thepresence of tell-tale arc-shaped scars at Cuarteron, Fiery Cross, Gaven, Hughes and Mischief
Reefs, indicating extensive propeller damage on the reef flats by boats likely harvesting giant
clams.925(c)

China’s Construction Activities on Seven Reefs in the Spratly Islands

852. The second aspect of the Philippines’ environmental submissions relates to Chinese construction
activities on seven features in the Spratly Islands: (a) Cuarteron Reef, (b) Fiery Cross Reef,(c) Gaven Reef (North), (d) Johnson Reef, (e) Hughes Reef, (f) Subi Reef, and(g) Mischief Reef.
853. Documents adduced by the Philippines indicate that in the period from the early 1990s until
2013, China undertook some construction and land reclamation on these features, typicallystarting with basic aluminium, wooden, or fibreglass structures supported by steel bars with

cement bases.926 Over time, China installed more sophisticated structures, including concrete
multi-storey buildings, wharves, helipads, and weather and communications instruments.927 Thelargest of the projects before 2013 was the construction of an artificial island at Fiery Cross
Reef of approximately 115 x 80 metres.928 Other States in the region, including the Philippines
and Viet Nam, undertook similar construction activities during the same period.929 Examples ofthe pre-2013 structures built by China can be seen below at Figures 13 and 14 on page 333.
854. The massive island-building project that China has embarked on since the end of 2013,
however, far exceeds the scale of these earlier construction projects. China has deployed a large
fleet of vessels to the seven reefs, primarily using heavy ‘cutter-suction dredge’ equipment, tocreate more than 12.8 million square metres of new land in less than three years.930
855. The ‘cutter-suction dredge’ method involves a ship-borne drill which is extended from thedredging vessel into the seabed. The drill’s rotating teeth act like picks that chisel away at theseabed or reef, breaking apart and extracting the soil, rock, and reef.931 This material is then926

Figure 12: Dredging Operations
Second Carpenter Report, p. 10, reproduced from “What China Has Been
Building in the South China Sea,” New York Times (27 October 2015)856. China’s largest suction cutter dredger is the Tian Jing Hao, reportedly capable of extracting
4,500 cubic metres per hour of sand, rock, and other materials from the surrounding seabed. 934
Photographs of the Tian Jing Hao are shown below, and at work, alongside other dredgers in theprocess of reclamation works at Mischief reef. China has also used “trailing suction hopper
dredgers” which collect loose materials from the seabed and shoot material onto the reef, as
illustrated in Figures 15 to 17 on page 335 below.
857. The environmental impact of such dredging methods are discussed in the Tribunal’s
considerations at paragraphs 976 to 983 below. In short, according to the Tribunal’s experts,
construction and dredging activities can impact reef systems in three ways:(a) direct

destruction of reef habitat through burial under sand, gravel and rubble; (b) indirect impacts onbenthic organisms such as corals and seagrasses via altered hydrodynamics, increased
sedimentation, turbidity, and nutrient enrichment; and (c) indirect impacts on organisms in thewater column, such as fishes and larvae, from sediments, chemical and nutrient release, andnoise.935

860. While some of these communications have concerned the effect of China’s construction workon the present proceedings (an issue discussed further in connection with the Philippines’
Submissions concerning the aggravation of the dispute, see Chapter VIII below), the Philippines
has also emphasised the environmental impact of China’s island-building project. For instance,on 13 April 2015, the Philippine Department of Foreign Affairs released the following
statement:
China’s massive reclamation activities are causing irreversible and widespread damage tothe biodiversity and ecological balance of the South China Sea/ West Philippine Sea. We
cannot accept China’s claim that its activities have not caused damage to the ecologicalenvironment of the South China Sea.
China has pursued these activities unilaterally, disregarding peoples in the surrounding
states who have depended on the sea for their livelihood for generations. . . .
Moreover, we note that China has tolerated environmentally harmful fishing practices by its
nationals at Bajo De Masinloc which breaches its obligations under the 1982 United
Nations Convention on the Law of the Sea (UNCLOS), the Convention on Biological
Diversity, and the Convention on International Trade in Endangered Species of Wild Fauna
and Flora (CITES).939

861. A more detailed statement was released on 23 April 2015 by the Philippine Bureau of Fisheries
and Aquatic Resources, following a comprehensive study by the University of the Philippines
on the damage inflicted to marine biodiversity and economic productivity.940
862. As detailed below at paragraphs 916 to 924, China maintains that its island-building project“had gone through science-based evaluation and assessment with equal importance given to
construction and protection” and that it had taken “full account of issues of ecologicalpreservation and fishery protection” and “followed strict environmental protection standards.”941

Calculations presented by the Philippines, estimate that China’s construction work as at
November 2015 had resulted in the creation of at least 231,000 square metres of new land on
Cuarteron Reef. 952

The same report indicates that China built a channel approximately

125 metres wide for large vessels to access and berth within a harbour cut out of the reef

ii.

Fiery Cross Reef

867. Fiery Cross Reef is an “open spindle-shaped atoll that extends for about 25 km from northeast
to southwest, with a width of about 6 km.”953 An extensive reef flat on the southwest end of thereef surrounds a small closed lagoon in its centre with a maximum depth of 12 metres.
According to the Tribunal’s coral reef experts, the present coral reef there developed
approximately seven to eight thousand years ago. 954 Abundant fisheries were reported insurveys from the late 1990s, and highly biodiverse coral communities were recorded in surveys
from 2004 and 2005.955 The Tribunal has found at paragraph 343 above that, while Fiery Cross
Reef was mostly submerged in its natural state, the atoll was encumbered by a rock thatremained exposed at high tide. The Tribunal classified Fiery Cross Reef as an Article 121(3)rock.
868. Chinese construction activities reportedly commenced at Fiery Cross reef in 1988 with thebuilding first of a small naval post, followed by an oceanographic observation post, pier, andseveral other buildings.956 Subsequent years saw the installation of communications systems
and lighthouses, and by 2013 the Philippines Army reported, based on photographic surveys,
that “Fiery Cross Reef is now a complete complex of buildings with significant communications
and defense and military features.” 957

By March 2013, further buildings, including agreenhouse and powerhouse had also been observed.958

869. By November 2014 there were reports that China was building a runway on Fiery Cross Reef.959
Land reclamation intensified and progressed rapidly throughout 2015.960 Images from 18 July
2015 showed the presence of at least 18 vessels unloading construction equipment. 961 By
November 2015, approximately 2,740,000 square metres of land had been created at Fiery
Cross Reef, with sand and rock dredged from the seabed covering virtually the entire platformof the southwestern reef flat. 962 China’s recent activities have created an artificial island
approximately 300 times larger than the pre-existing installations, which covered an area ofapproximately 11,000 square metres. The installations now include a three-kilometre runway, a
630,000-square-metre harbour, multiple cement plants, support buildings, temporary loadingpiers, communication facilities, defence equipment, two lighthouses, a greenhouse, two helipads
and a multi-level administrative facility adjacent to the runway. 963
870. The massive scale of China’s construction efforts on Fiery Cross Reef is apparent in aerial andsatellite photography. Satellite photography reproduced as Figures 20 and 21 on page 343
shows the reef’s progression from its nearly natural state in January 2012 (with China’s original
installation just visible at the southern end) to an artificial island complex, complete with a large
runway, covering the entire reef platform in October 2015.

Gaven Reef (North)871. Gaven Reef (North) sits on the western end of the largely submerged atoll of Tizard Bank.964 Its
reef flat extends approximately 1.9 kilometres from north to south and 1.2 kilometres from east
to west and has no central lagoon.965 According to surveys conducted between 1998 and 2005,
fisheries resources at Gaven Reef (North) were lower than at Fiery Cross Reef, but Gaven Reef

(North) was found to have the highest resources for longlining among the seven reefs.966 The
Tribunal has found at paragraph 366 above that, in its natural state, Gaven Reef (North)included a small sand cay at its north-east end that remained exposed at high tide. The Tribunal
classified Gaven Reef (North) as an Article 121(3) rock.
872. China has reportedly had a presence on Gaven Reef (North) since 1988 and, by 1996, had built
an outpost with barracks and two octoganal structures.967 A three-storey concrete building with
communications equipment was observed by Philippine surveillance in May 2005, and further
enhancements were noted in 2011.968
873. Intense reclamation work began at Gaven Reef (North) in the spring of 2014. 969 Philippine
surveillance in May 2015 at Gaven Reef (North) observed a new helipad, watch post, and wharf
expansion.970 Within the span of a year, China transformed Gaven Reef (North) from a coral
reef to an artificial island measuring approximately 300 by 250 metres, created from 136,000
square metres of materials dredged from the seabed.971
874. The change in Gaven Reef (North) is readily visible in aerial and satellite photography. China’s
original installation, as well as the naturally occurring sand cay, are barely visible at the northend of the reef in satellite imagery from January 2012, reproduced as Figure 22 on page 347. In
contrast, a large artificial island in the shape of a sideways “Y” dominates the reef in imagery

Its fisheries resources were lower than those recorded at the other reefs, and live coral covered
approximately 15 percent of the reef flat.973 The Tribunal has found at paragraph 351 above thatJohnson Reef has been consistently reported as including rocks that remain exposed at high tideand classified Johnson Reef as an Article 121(3) rock.
876. China has reportedly had a presence on Johnson Reef since 1988. 974 By 1992, China hadconstructed a “heavily fortified area with an observation tower,” to which was added, by 2006, a
three-storey concrete building, communications eqiupment, solar panels, and a helipad.975
877. China began extensive reclamation activities at Johnson Reef in the spring of 2014. Aerial
reconnaissance conducted by the Philippines on 9 May 2015 detected further buildings, solar
panels, paved roads, and piers.976 A ceremony was held by the Chinese Ministry of Transport
for the construction of a lighthouse on Johnson Reef on 26 May 2015.977 By November 2015,
China had created an artificial island measuring approximately 109,000 square metres, nearly
1,000 times larger than the previous structure.
878. The change in Johnson Reef is readily visible in aerial and satellite photography. China’s
original installation cannot even be seen without enlargement in satellite imagery fromMarch 2013, reproduced as Figure 24 on page 347. In contrast, a large artificial island, alongwith a dredged harbour channel into the centre of the reef is readily visible in imagery from

lower than the other reefs discussed in this Chapter). 980

The Tribunal has found atparagraph 358 above that Hughes Reef is a low-tide elevation.
880. China has reportedly had a presence on Hughes Reef since 1988. By October 2006, China had
installed a three-storey concrete building and helipad. 981 By February 2013, there wereadditional power-houses and communications equipment, but the total land area for thesestructures was still only approximately 380 square metres. 982
881. China began large-scale reclamation activities at Hughes Reef in the spring of 2014. Aerial
reconnaissance by the Philippines on 9 May 2015 detected a permanent pier, a “massive onshore
construction of a 6-storey building,” and large cargo vessels transporting sand sediments for“newly reclaimed land”. 983 By November 2015, China had created an artificial island on
Hughes Reef measuring around 75,000 square metres, on which it has built coastal fortifications,defensive towers, and a multi-level facility.984 China also enlarged the entrance to the reef tocreate a 118-metre wide access channel for larger vessels.
882. The change in Hughes Reef is readily visible in aerial and satellite photography. China’s
original installation cannot even be seen without enlargement in satellite imagery from February
2010, reproduced as Figure 26 on page 351. In contrast, a large artificial island, along with adredged harbour channel into the centre of the reef is apparent in imagery from September 2015

Award of 12 July 2016a closed atoll, with no passages into the lagoon.985 According to a 2002 study, Subi Reef washome to a rich variety of over 300 macrobenthic species,986 although fisheries surveys from thelate 1990s indicate that the reef may already have suffered from overfishing. Coral surveys
conducted in 2007 recorded between 64 and 74 species of coral at Subi Reef, with live coral
cover highest in the inner reef flat and lagoon areas.987 The Tribunal has found at paragraph 373
above that Subi Reef is submerged at high tide in its natural condition and classified it as a
low-tide elevation.
884. According to Philippine military records, China has had a presence on Subi Reef since 1989,
and by 1994, “considerable improvements” there included at least five buildings, a wharf andhelipad. By October 2006, a four-storey concrete building was present, and by February 2013,
there were more concrete structures, a lighthouse, and communications equipment.988
885. China began large-scale dredging work at Subi Reef in the summer of 2014,989 which intensifiedin early 2015. Photographs taken on 7 July 2015 showed over 80 ships and a dredger at Subi
Reef.990 A few weeks later, two cutter suction dredgers, 44 cargo supply vessels, 22 tugboats,
and a floating barge crane were seen reclaiming both sides of Subi Reef.991 By November 2015,
China had created an artificial island measuring approximately 3,950,000 square metres,“covering the majority of the reef.”992 China has built the beginning of what appears to be athree-kilometre runway, a large multi-level facility, reinforced sea walls, towers, andcommunications facilities. China also created a 230-metre-wide access channel.
886. The massive scale of China’s work on Subi Reef and the transformation of nearly the entire
atoll into an artificial island is apparent in aerial and satellite photography and can be seen insatellite imagery from July 2012 and November 2015, reproduced as Figures 28 and 29 on

Mischief Reef

887. Mischief Reef is a large oval-shaped atoll, approximately 6.5 kilometres wide, with three natural
entrances into the lagoon.993 The lagoon featured a number of well-developed patch reefs withmassive, foliose, and branching corals.994 A 2007 survey found 94 species of stony corals there,
and live coral cover of 51 percent on the reef slope. Fisheries surveys from the late 1990s
described Mischief Reef as having some ‘production value,’ although the reef appeared to bealready under pressure of increased fishing by 2005. 995

The Tribunal has found atparagraph 378 above that, in its natural condition, the highest rocks at Mischief Reef covered athigh tide. The Tribunal classified Mischief Reef as a low-tide elevation.
888. China’s construction work at Mischief Reef is discussed in greater detail below in connection
with the Philippines’ Submissions No. 12(a) and 12(c), relating to the lawfulness of constructing
artificial islands within the Philippines exclusive economic zone. In brief, Chinese construction
activities on Mischief Reef date back at least to January 1995, starting with “typhoon shelters”.
By 1999, Mischief Reef featured multi-storey structures, communications equipment, wharves
and a helipad.
889. Intense land reclamation began at Mischief Reef in January 2015. Progress was rapid, with up
to nine dredgers working in the reef simultaneously, according to satellite imagery analysed by
the Philippines. By November 2015, the total area of land created by China on Mischief Reef
was approximately 5,580,000 square metres.996 The southern entrance to Mischief Reef was
widened from its original 110 metres to 275 metres.
890. The massive scale of China’s work at Mischief Reef and the transformation of nearly the entire
atoll into an artificial island is apparent in satellite imagery, reproduced as Figures 31 and 32 at
page 405 below.

The Philippines’ Position

891. The Philippines’ submits that China’s actions have damaged the diverse and fragile ecosystemof the South China Sea. The Philippines states that “if unchecked [China’s] activities will993

continue to pose a significant threat to the marine environment of the South China Sea, and of
all of the States which border the Sea.”997
892. The Philippines stresses that China’s obligation to protect and preserve the marine environmentis “not dependent on deciding which Party, if any, has sovereignty or sovereign rights or
jurisdiction over Scarborough Shoal or Second Thomas Shoal or Mischief Reef” or any of theother features named in the amended version of Submission No. 11.998 What matters, according
to the Philippines, is rather whether China has “jurisdiction or control over the harmful fishingpractices, the land creation and the construction activities which threaten the marine
environment at those locations and elsewhere in the South China Sea.”999
893. According to the Philippines, China’s island-building activities do not fall within thejurisdictional exclusion for “military activities” under Article 298(1)(b).1000 In this respect, thePhilippines notes that China did not invoke the military activities exception, and that in any
event China has repeatedly characterised its island-building as being for civilian purposes.1001
The Philippines also submits that “mixed-use projects” and situations “in which a military unit
is used to protect other activities” are not covered by the military activities exception.1002(a)Harmful Fishing Practices and Harvesting of Endangered Species

894. The first component of the Philippines’ argument on Submission No. 11 is that China’s
toleration, encouragement of, and failure to prevent environmentally destructive fishingpractices by its nationals violates the “duty to protect and preserve the marine environment” set
forth in Articles 192 and 194 of the Convention.1003 The Philippines complains that China has
allowed “its fishermen to harvest coral, giant clams, turtles, sharks and other threatened or
endangered species which inhabit the reefs” and “to use dynamite to kill fish and destroy coral,
and to use cyanide to harvest live fish.”1004

Award of 12 July 2016895. The Philippines relies principally on the incidents that took place near Scarborough Shoal on
10, 23, and 26 April 2012 (described above at paragraphs 835 to 844), when the Chinese fishingvessels caught with caches of endangered corals and clams were operating under the clear
protection of Chinese Government vessels.1005 The Philippines nevertheless points to incidents
from 1998 to 2006 (described above at paragraphs 827 to 834) as evidence of a continued
pattern of environmentally destructive activities by Chinese fishing vessels “that had been
carried on over many years, with China’s full knowledge.”1006
896. The Philippines explains that the extraction of corals is very damaging to the marine
environment because it “reduces the structural complexity of reefs and affects the ability of thereef to support fishes and other animals.”1007 Citing the First Carpenter Report, the Philippines
notes that it can take decades for similar numbers of corals to replenish.1008
897. The Philippines observes that harvesting of giant clams, sea turtles, and other endangered
species compounds environmental impact and reduces biodiversity.1009 Extracting giant clams
is especially problematic because, as Professor Carpenter explains, they are important elementsof the coral reef structure and also because the method of harvesting them entails crushingsurrounding corals.1010
898. With respect to the use of dynamite, the Philippines explains that using explosives pulverises
coral, weakens the structure of the reef, and reduces biodiversity by killing fish and destroying
their habitat.1011 As for cyanide, which is used to immobilise fish so that they can be caught live
for the aquarium and restaurant trades, the Philippines notes that it can kill or injure non-target
species and encourage unsustainable catch levels. Because the stunned fishes may be hidden incoral crevices, the usage of cyanide leads to the coral being broken apart by fishermen to
retrieve them.1012

899. Professor Carpenter explained how these practices impact the highly interconnected andinterdependent ecosystem of the South China Sea.1013 He confirmed the conclusions in his firstreport, that:1014
These activities not only reduce the potential sustainable fisheries on the reefs themselves,
but also can have detrimental effects on biodiversity and fisheries in the greater Philippine
archipelago. . . .
With more marine species per unit area than any other region on earth . . . . the Philippines
is seen as the ‘Amazon River Basin of the Seas’. . . . Because of the connectivity of theeastern South China Sea to the greater Philippine archipelago through prevailing ocean
currents, it is important to ensure the sustainable stewardship of Scarborough Shoal and theSpratly Islands.
. . . [C]oral reef degradation of Scarborough Shoal and the Spratly Islands affects the wider
marine ecosystem of the South China Sea. Coral reefs provide ecosystem services to theopen ocean around these reefs. . . . Coral reef degradation decreases the capacity of reefs tosupport [visiting foraging species] and . . . reduces the capacity of the reef for . . . cleaner
organisms and can impact the health of marine fishes . . . . 1015(b)

China’s Construction Activities on Seven Reefs in the Spratly Islands

900. The Philippines notes that even before the extensive artificial island-building programcommenced in late 2013, China’s installations on the features in the Spratlys between the early
1990s and 2013 had “inevitably harmed the fragile ecosystem there, and resulted in significant
damage to the habitats of vulnerable species.”1016
901. The Philippines notes, however, that such damage is dwarfed by the “catastrophic”
environmental impact of the more recent construction activities, 1017 stating that “the loss ofseven major reef features to land creation within 1.5 years will have a huge impact on theecological integrity of not only the Spratly reefs but also of the South China Sea.” 1018 The
Philippines observes that with “millions of tons of rock and sand” dredged from the seabed anddeposited on shallow reefs, “land creation on this massive scale inevitably destroys that part of
the reef.”1019 Separate from the destruction of the reef itself, sedimentation caused by the works
smothers coral, depriving it of sunlight and impeding its ability to grow.1020

902. The Philippines acknowledges that, for obvious reasons, it was unable to investigate recent
conditions at Mischief Reef (and the other features address in Submission No. 11).
Nevertheless, the Philippines argues that the Tribunal can use satellite images and scientificreports to “draw the obvious inferences about the harm that large-scale land creation andconstruction activities will cause.”1021
903. At the Hearing on the Merits, Professor Carpenter recalled that “abrupt man-made alterations toshallow reef features,” such as China’s island-building “directly impacts the functioning ofthese delicate reefs and alters the topography that has taken thousands of years to form.” 1022 He
summarised the “very significant damage to this complex coral reef ecosystem” as follows:
The total destruction of a large swathe of reef structures through demolition and burying
and landfill is a catastrophic disturbance of the reef. The wholesale removal and destructionof coral reef habitat by the direct destruction and replacement of the shallow portions of thereef ecosystem with man-made structures removes vital components of available reef
habitat that have functioned as a single ecosystem for many generations of reef inhabitants.
This causes dramatic reductions in populations and local extinction of prominent fishes andinvertebrates.
This is of particular concern because there are a number of species listed as threatened withextinction in the South China Sea. . . . The direct ecosystem harm . . . can be multiplied
many times over by the wider effects of sediment plumes caused by island building. . . .
This sediment cloud covers large areas of the reefs, smothers the coral, and results inwidespread destruction of the reef. This in turn dramatically reduces overall primary
productivity and topography of the reef, limiting its ability to sustain life.
Recovery from these severe disturbances is uncertain . . . . Here, demolition and burial andlandfill has resulted in the total destruction of large swathes of reef structures thatdestabilise the reef substrate and negatively impact the potential for recovery. Reefs thathave been smothered by sedimentation are unlikely to ever recover if unstable sediments
remain in place, because reef building requires hard substrate . . . to recruit and thrive. 1023

904. Professor Carpenter then addressed a variety of questions from the Tribunal, including as to theprospects of replenishment, damage caused by sedimentary plumes and turbidity, 1024 and thereliability of satellite imagery (which he supported by reference to independent studies reachingsimilar results).1025 He reported on his efforts to find Chinese statements about the ecologicalimpact of the construction activities and noted that the only report he identified, a 500-wordstatement 1026 from China’s State Oceanic Administration, contains assertions “contrary to

everything that we know about coral reef ecology and conservation.”1027 This statement (the“SOA Statement”) did not alter his conclusion that the Chinese activity “constitutes the most
rapid nearly permanent loss of coral reef area in human activity.”1028
905. The Philippines made similar observations about a slightly longer report prepared by SOA
scientists (the “SOA Report”), which the Tribunal drew to the Parties’ attention on 5
February 2016.1029 According to the Philippines, that report was also “thoroughly contradictedby the evidence,”1030 contained inaccurate statements about timing, flawed predictions about
recovery periods, and misplaced analogies with dredging projects in Australia and othercountries.1031(c)Interpretation and Application of Part XII of the Convention

906. In connection with the marine environment, the Philippines alleges China has breached
Articles 123, 192, 194, 197, 205, and 206 of the Convention.
907. The Philippines recalls that the general obligation on States under Article 192 to “protect andpreserve the marine environment”—which it considers to form part of customary internationallaw 1032 —covers areas within national jurisdiction as well as areas beyond national
jurisdiction.1033 According to the Philippines, this requires States to take “active measures” toprevent harm, to “conserve marine living resources,” and to “preserve the ecological balance ofthe oceans as a whole.” 1034
908. The Philippines notes that the interpretation of Article 192 may be guided by reference tostandards in other multilateral environmental instruments, such as CITES and the CBD. 1035
Likewise those instruments provide content for the obligation under Article 194(5) with respect
to measures necessary to protect and preserve “rare or fragile ecosystems” and “places thatprovide habitats for . . . endangered species.”1036

909. The Philippines notes that States are only required to take appropriate measures and act withdue diligence. In this case, however, the Philippines argues that the clear evidence of deliberate
and irreparable ecological destruction cannot be squared with China’s own laws onenvironmental protection.1037 While China’s island-building activities at the seven reefs were
unquestionably within the control and jurisdiction of China, the Philippines acknowledges thatthe unlawful harvesting was carried out by non-government Chinese fishing vessels and that
“China is not responsible for the actions of its fishermen.” China is, however, “responsible forits own failure to control their illegal and damaging activities.”1038 The Philippines argues that
China has “not even attempted to do so” but rather has actively “supported, protected andfacilitate[ed]” their harmful practices.”1039 The Philippines also observes that as the flag State,
China is obliged to monitor and enforce compliance with its laws by all ships flying its flag.1040
910. The Philippines highlights five obligations that it considers applicable to States under Part XIIof the Convention and relevant in the context of this case:1041(a)

To protect and preserve marine ecosystems: The Philippines observes that coral reefs area fragile and vitally important part of the marine ecosystem and argues that “creating
artificial islands out of coral reefs is the worst possible way to treat these fundamental
ecological building blocks.”1042(b)

To ensure sustainable use of biological resources: The Philippines notes that this reflects
a long-recognised duty to conserve living resources. 1043 Blast fishing and the use of
cyanide are wasteful and unsustainable, and violate Articles 192 and 194 (including as
marine pollution),1044 whether the methods are used in the territorial sea or beyond.1045(c)

To protect and preserve endangered species: The Philippines argues that this is implicit
in Article 194(5). According to the Philippines, the harvesting of giant clams in April

The South China Sea Arbitration
Award of 12 July 20162012 under the protection of Chinese authorities constitutes a clear violation of Articles
192 and 194.1046(d)

To apply a precautionary approach in all of these respects: The Philippines considers
this obligation applicable to China, but argues this is not necessary to the Tribunal’s
findings in the current case because the risks to the marine environment are obvious andthere can be no uncertainty.1047(e)

To consult and cooperate with the relevant coastal States: The Philippines draws thisobligation from Articles 197 and 123 of the Convention, the latter of which takes into
account the “characteristic regional features” which would include the fundamental
biological and ecological importance and fragile nature of the coral reef ecosystem of theSouth China Sea.1048 The Philippines submits that there is very little evidence of genuine
Chinese cooperation on matters of environmental protection in the South China Sea. 1049
The Philippines considers China’s behaviour towards the Philippines and other States
bordering the South China Sea to be aggressive rather than cooperative.1050

911. Related to the failure to coordinate is, for the Philippines, a failure to assess and communicate.
The Philippines argues that China was “fairly and squarely” required to carry out anenvironmental impact assessment (“EIA”) within the meaning of Article 206 of theConvention.1051 At a minimum, the Philippines argues an EIA should have assessed possible
effects on the marine ecosystem of the South China Sea, the coral reefs at issue, the biodiversity
and sustainability of living resources there and endangered species.1052 The Philippines argues
that there is simply no evidence that China carried out such an EIA and no science-based
evaluation has been made public or communicated to the Philippines or to “the competentinternational organizations” as required by Articles 205 and 206 of the Convention. 1053
According to the Philippines, the 500-word SOA Statement was a “pseudo-evaluation . . .
plainly not an EIA.”1054 The (slightly longer) SOA Report also fell short, in its view.1055 The

Philippines observed that even without appearing in the arbitration, China could easily havemade its evaluation available to the Tribunal and added that China’s non-appearance should notexempt it from “the normal burden of proof that attaches to any assertion of fact in inter-State
proceedings.”10564.

China’s Position

912. China has not directly stated its position with respect to the allegations as presented in thePhilippines’ Submissions No. 11 and 12(b). Nevertheless, China’s position can be discerned
from contemporaneous official statements.
(a)Harmful Fishing Practices and Harvesting of Endangered Species

913. Statements of Chinese officials relating to the incidents between 1998 and 2006 were primarily
focused on asserting Chinese sovereignty over Scarborough Shoal and objecting to interference
by Philippine authorities. Nevertheless, on a few occasions Chinese officials did addressenvironmental concerns raised by the Philippines in connection with Scarborough Shoal. For
example:(a)

According to a record of a meeting in March 2000, a Chinese Foreign Ministry official
expressed to the Philippine Ambassador in Beijing her “particular concern about thepractice of dynamite fishing” and that she had “requested the [Ministry of Agriculture] todo something about the situation.”1057(b)

Following the confiscation of endangered species from Chinese fishing vessels in
February 2001, the political counsellor from the Chinese Embassy in Manila reiterated
that “Scarborough Shoal is part of Chinese territory and . . . Chinese fishermen have beenfishing in the area since ancient times” but reportedly added that “[w]ith regard to theillegal catching of turtles and corals, . . . . China has a law on this and those who violate
the law will be punished.” 1058

Award of 12 July 2016(c)

In March 2001, the Asian Department Deputy Director-General of the Chinese Foreign
Ministry stated to the representative of the Philippine Embassy in Beijing that “theChinese Government is always against illegal fishing.”1059

914. By contrast, following poaching incidents in 2005 and 2006, China’s Vice Foreign Minister did
not mention environmental issues and instead expressed dissatisfaction with the Philippine
Navy’s continued patrol of vessels in Scarborough Shoal, which he considered to have violated
the sovereignty and maritime rights of China.1060 China’s opposition to Philippine interference
at Scarborough Shoal persisted through 2012, when in April China confirmed that “relevant
Chinese authorities” had been dispatched to “protect the safety and legitimate fishing activities
of Chinese fishermen and fishing vessels.”1061
915. Although a Chinese official stated in May 2015 that, as a State party to the CBD and to CITES,“China will strictly observe provisions of the conventions and honour her obligations in goodfaith,”1062 the Tribunal has seen no evidence that Chinese fishermen involved in poaching ofendangered species have been prosecuted under Chinese law. China did not respond to reports
forwarded by the Tribunal in December 2015 and February 2016 concerning the widespread
removal of giant clams by propeller cutting in and around features under Chinese control.1063(b)

the independent experts with “analysing any documents concerning China’s assessment of theenvironmental impact of its activities.”1065
917. On 9 April 2015, a Chinese Foreign Ministry Spokesperson made the following remarks about
Chinese construction activities at Mischief Reef:
China’s construction projects on the islands and reefs have gone through scientificassessments and rigorous tests. We put equal emphasis on construction and protection byfollowing a high standard of environmental protection and taking into full consideration theprotection of ecological environment and fishing resources. The ecological environment of
the South China Sea will not be damaged. We will take further steps in the future tomonitor and protect the ecological environment of relevant waters, islands and reefs. 1066

918. Similar remarks were made by the Director-General of the Department of Boundary and Ocean
Affairs of China’s Foreign Ministry on 27 May 2015.1067
919. A Chinese Foreign Ministry Spokesperson noted, on 16 June 2015, that the “main purpose” ofthe construction activities is to “meet various civilian demands and better perform China’s
international obligations and responsibilities in the areas such as . . . ecological environment
conservation.”1068
920. More recently, a Chinese Foreign Ministry Spokesperson provided the following response to aquestion about whether China’s massive land reclamation activities have destroyed coral reefs
in the South China Sea “on a large scale”:
The Nansha Islands are China’s territory. As owners of the Nansha Islands, China cares
about protecting the ecological environment of relevant islands, reefs and waters more thanany other country, organization or people in the world.
China’s activities on the Nansha Islands strictly follow the principle of conducting green
project and building ecological islands and reefs. Based on thorough studies and scientificproof, China adopts dynamic protection measures along the whole process so as to combine
construction with ecological environmental protection and realize sustainable developmentof islands and reefs. To be specific, China takes the approach of “natural simulation” which
simulates the natural process of sea storms blowing away and moving biological scraps
which gradually evolve into oasis on the sea. The impact on the ecological system of coral
reefs is limited. Once China’s construction activities are completed, ecological1065

921. In light of China’s references to “thorough studies”, “scientific assessments”, and “rigorous
tests”, the Tribunal has sought further information on environmental studies conducted by
China. Thus, during the Hearing on the Merits, the Tribunal asked the Philippines if it was“aware of any experts from China or elsewhere that have published or articulated views about
the environmental impact of China’s activities or toleration of activities by others within its
control that are contrary or different to those of the Philippines.” 1070 The Philippines noted“problems of access to the features occupied by China” and the “rather expedited timeframe,”and reported that its searches had turned up only “a brief statement from the State Oceanic
Administration.”1071
922. The SOA is an administrative agency under the Chinese Ministry of Land and Resources,
responsible for, among other things, the management of sea area uses, the strategic developmentof the sea, marine environmental protection, and the development of uninhabited islands. 1072
The SOA Statement located by the Philippines was entitled “Construction Work at Nansha
Reefs Will Not Harm Oceanic Ecosystems” and included the following:
The land reclamation work at some of the reefs of China’s Nansha Islands will becompleted in the near future. In order to ascertain the effects of the construction work on
oceanic ecosystems, scientific studies have been conducted by a team of experts andresearchers from the fields of civil engineering, marine engineering, marine ecology,
environment protection, and hydrogeology.
1.

The construction work will abide vigorously by the rules of environment protection.

The expansion of the Nansha reefs will abide rigorously by the concept of “Green
Construction, Eco-Friendly Reefs” in protecting the ecosystems. . . .
2.

The construction work employs the method of nature simulation.

The expansion of the Nansha reefs uses the “nature simulation” method as its
comprehensive technical concept. This method simulates the displacement of bioclasts
such as corals and sands during wind storms and high waves; this biological detritus settles
on the combined equilibrium points of the shallow reef flats to form stable supratidal zones
which then evolve into oceanic oases. Big cutter suction dredgers are used to collect theloose coral fragments and sands in the lagoon and deposit them on bank-inset reefs to form
supratidal platform foundation on which certain kinds of facilities can be built. Throughthe natural functions of the air, the rain, and the sun, paving it with some quick man-made1069

3.

The construction work adopts the measures of ecological protection.

a.

To plan construction projects on bank-inset reefs made of basically dead corals: use
a cutter suction dredger to collect loose coral fragments and sands from flat lagoon
basins, which do not constitute hospitable environment for corals . . . .

b.

We used a new “dig, cutter suction, blow, and fill” land reclamation method tointegrate digging, transporting, and filling into the construction work; this results inthe least ecological impact to the coral reefs.

The construction embraces the concepts of containment of scope, high efficiency,
and sustainability. The duration of construction for every land reclamation projecton the reefs will only be about several months.

4.

Conclusion

The construction work on the Nansha reefs stresses ecological protection. Many protection
measures were adopted in the stages of planning, design, and construction. Good results
have been obtained, and the ecological impact on the coral reefs is partial, temporary,controllable, and recoverable.1073

923. The Tribunal subsequently identified the SOA Report, dated 10 June 2015, by researchers fromthe First Ocean Research Institution of the SOA. The authors are not State officials, but work
for a government-sponsored organisation. The following are extracts from the SOA Report,
which was provided to the Parties for comment:. . . Due to global seawater warming, ocean acidification, overfishing, development ofcoastal areas and other reasons, modern coral reefs are degenerating rapidly. . . . The site
selection, construction and postconstruction monitoring of the construction at Nansha Reefs
are in all respects in compliance with domestic laws and regulations. The construction wasundertaken with an emphasis on the protection of ecosystem and fishery resources, carriedout after scientific assessment and feasibility studies.
1.

There has been abundant global experience in construction in coral reef areas. . . Nowadays, coral reefs are utilized mainly for four purposes. First, for national defence
and military purposes. [e.g., U.S. and Japan] . . . Second, for coastal tourism development.
. . . . Third, for the construction of port terminals. [e.g., Bahamas, Sudan, Papua New
Guinea and Australia]. . . . Of course, rigorous protection standards must be complied withwhen carrying out construction in the coral reef areas.
2.

General information on the Coral Reef Ecosystem of Nansha Reefs

Nansha Reefs present typical tropical reef landscape. . . . It is estimated that there are
between 127 and 200 species of shallow water reef building corals (hermatypic corals)
surrounding the Nansha reefs.
. . . . Research has shown that the South China Sea is not a body of closed waters, therefore
nutrients and food organisms can be replenished constantly from surrounding waters . . . . The
1073

SOA Statement, pp. 1-2.

367

The South China Sea Arbitration
Award of 12 July 2016

severe degeneration of coral reefs worldwide has been exacerbated also by human factors
such as overfishing, illegal destruction, excessive tourism development activities . . . .
The amount and number of species of coral reefs in China’s South China Sea is also
showing a tendency of rapid decrease. . . . Such decrease is mainly due to natural factors,
with overfishing being the major human factor.
3.

Eco-protection measures implemented during the construction activities. . . First, enhance the protection through legislation. . . . Second, actively fulfilling
obligations under international conventions including the [CBD]. . . . Third, establish
marine natural reserves to protect coral reef ecosystems. . . . Fourth, actively conduct
research on the restoration of coral reefs. . . .
. . . . The government has evaluated all construction plans available and has chosen the
optimal plan while excluded the ones that would have a bigger impact on marine
environment. . . .
As to scientific site selection . . . most of the construction sites selected are located in reef flatswith the lowest hermatypic coral coverage or where hermatypic corals are mostly dead.
. . . . China had drawn on the construction technology and environmental protection
standards implemented in similar projects. . . . The following specific environmental
protection measures were implemented to minimise the impact on coral reefs, including:

4.

1)minimising the extent of the reclamation and dredging areas;

2)

setting trash collecting screens;3)

timing construction reasonably, trying to avoid spawn periods of red snapper(mid-April), tuna (peak from June to August) and bonito (from March toAugust);4)

monitoring the change of grain size of sand sediments regularly . . . tomaintain the water quality of coral reef areas;5)

reducing construction intensity during the peak of growth of Nansha and
Xisha coral reefs . . . . ;6)monitoring the growth and health of coral reefs in construction areas andindicators such as species . . . in coral reef areas;

7)

centrally collecting the waste water and solid waste produced from life andconstruction to be sent for treatment at land facilities of harbours;

8)

using newer vessels to ensure no oil spill happens; listening to weather andmarine condition forecasts regularly. . . .

Assessment of the environment impact of Nansha construction activities on coral
reef systems. . . The Nansha coral reefs were rated as “sub-healthy” before the construction. Afterassessing the construction’s environmental impact on coral reefs, the health of Nansha coral
reefs were still rated “sub-healthy” after the construction was completed. Therefore, theconstruction activities neither affected the health of . . . nor harmed the coral reef ecosystems.
In fact, due to the strong currents and waves . . . the water bodies are updated fairly fast sothat little suspended sands are produced from the constructions, leaving the photosynthesisof corals largely unaffected. Because the sites are located in areas where coverage of coral
reefs is low, the overall community structure [and] the physical and chemical living
environment of coral reefs are not fundamentally changed, therefore their health was not
significantly harmed by the construction activities. . . .

368

The South China Sea Arbitration
Award of 12 July 2016

As to the impact of reclamation activities on fishery resources . . . the construction avoided
the spawning seasons of the main economic species [including tuna], the impact on fisheryresources is reduced to the minimum. . . . [The] South China Sea is not a body of closed
waters, therefore nutrients and food organisms can be replenished constantly fromsurrounding waters. . . .
Research has also shown that coral reefs have strong capability of self-restoration.
Generally speaking, coral reefs that have been severely damaged by natural factors or
human activities can be restored initially in 5-10 years provided that effective measures aretaken, and complex and complete ecosystems can be fully restored in 50-100 years.
. . . [T]he conclusion can be reached that the construction activities did not adversely affectthe regional coral reef ecosystems. . . . The assessments are objective. Even so, after theconstruction is completed, it is important to enhance monitoring of regional ecosystems andimplement measures including release, coral restoration and transplantation in order tobetter protect the coral reefs.1074

924. On 5 February 2016, the Tribunal referred the Parties to the above SOA Statement and SOA
Report, as well as to a number of general SOA “Communiqués on Marine Environment” andtechnical guidelines for assessing marine ecosystem health. At the same time, the Tribunal
directly invited the Chinese Government “to indicate whether it has conducted an environmental
impact study per Article 206 of the Convention and, if so, to provide the Tribunal with a copy.”
China did not respond to the Tribunal’s request.

The Tribunal’s Considerations(a)

The Tribunal’s Jurisdictioni.

Jurisdiction over Submission No. 11 in its Original Form

925. The Tribunal recalls that in its original form, Submission No. 11 sought a declaration that
“China has violated its obligations under the Convention to protect and preserve the marine
environment at Scarborough Shoal and Second Thomas Shoal.”1075
926. In its Award on Jurisdiction, the Tribunal held that Submission No. 11 reflects a disputeconcerning the protection and preservation of the marine environment at relevant features within
the South China Sea and the application of Articles 192 and 194 of the Convention.1076 The
Tribunal found that this is “not a dispute concerning sovereignty or maritime boundary
delimitation, nor is it barred from the Tribunal’s consideration by any requirement of Section 1of Part XV.”1077

Award of 12 July 2016

927. The Tribunal noted that because the environmental obligations in Part XII apply to Statesirrespective of where the alleged harmful activities took place, its jurisdiction is not dependent
on the question of sovereignty over any particular feature, on a prior determination of the statusof any maritime feature, on the existence of an entitlement by China or the Philippines to an
exclusive economic zone in the area, or on the prior delimitation of any overlapping
entitlements.1078
928. The Tribunal likewise held that the other possible exceptions in Article 298 of the Convention
posed no bar to its jurisdiction over Submission No. 11.1079 The harmful fishing and harvesting
practices complained of in the Submission as originally formulated have no connection with“military activities”. To the extent the incidents could be characterised as related to “lawenforcement activities”, the Tribunal pointed out that the law enforcement activities exception
in Article 298(1)(b) would not in any event apply.
929. First, the law enforcement activities exception concerns a coastal State’s rights in its exclusive
economic zone and does not apply to incidents in a territorial sea. Thus, the exception could not
be relevant to incidents at Scarborough Shoal.1080
930. Second, although the status of Second Thomas Shoal and the question of whether the feature
was potentially within the entitlement of either China or the Philippines to an exclusive
economic zone were undetermined at the time of the Award on Jurisdiction, the Tribunal notedthat Article 297(1)(c) expressly reaffirms the availability of compulsory dispute settlement for
disputes concerning “alleged violations of international rules and standards for the protection
and preservation of the marine environment.”1081 The Tribunal’s decision in this Award that
Second Thomas Shoal is a low-tide elevation located in an area that can only form part of the
exclusive economic zone of the Philippines (see paragraph 646 to 647 above) further confirms
1078Award on Jurisdiction, para. 408.

1079

Award on Jurisdiction, para. 408. Article 298, which allows States the option of excluding fromcompulsory dispute settlement certain categories of disputes, including “(1)(b) disputes concerning
military activities, including military activities by government vessels and aircraft engaged in noncommercial service, and disputes concerning law enforcement activities in regard to the exercise ofsovereign rights or jurisdiction excluded from the jurisdiction of a court or tribunal under article 297,
paragraph 2 or 3.” Article 297(2) concerns marine scientific research and Article 297(3) concerns
fisheries. Cases under Article 297(1) are therefore not excluded. Article 297(1)(c) includes cases “whenit is alleged that a coastal State has acted in contravention of specified international rules and standards
for the protection and preservation of the marine environment which are applicable to the coastal Stateand which have been established by this Convention or through a competent international organization or
diplomatic conference in accordance with this Convention.”

1080

The Tribunal has found Scarborough Shoal to be an Article 121(3) rock, capable of generating a territorialsea, but not an exclusive economic zone. See paragraphs 554 to 556 above.

The South China Sea Arbitration
Award of 12 July 2016that the law enforcement exception in Article 298(1)(b) has no application in thesecircumstances.
931. Accordingly, the Tribunal found that it has jurisdiction over the dispute relating to Submission
No. 11 in its original form.
ii.

Jurisdiction over Submission No. 12(b) and Submission No. 11 as Amended

932. In its Award on Jurisdiction, the Tribunal noted that Submission No. 12 reflects a disputeconcerning China’s activities on Mischief Reef and the effects of those activities on the marine
environment. The Tribunal noted that this dispute does not concern sovereignty or maritime
boundary delimitation, nor is it barred from the Tribunal’s consideration by any requirement of
Section 1 of Part XV.1082 However, the Tribunal deferred taking a final decision on jurisdiction
over Submission No. 12, in light of factors discussed below at paragraphs 1024 to 1028. The
only such factor of relevance to paragraph (b) of Submission No. 12 (relating to the marine
environment) was the possible application of the exception in Article 298(1)(b) of theConvention, which excludes disputes concerning military activities from the Tribunal’s
jurisdiction. The Tribunal considered it preferable to assess the specifics of China’s activities
on Mischief Reef, and whether such activities are military in nature, in conjunction with themerits.1083
933. As already noted, the Tribunal subsequently granted the Philippines leave to amend Submission
No. 11 to encompass the marine environment at Cuarteron Reef, Fiery Cross Reef, Johnson
Reef, Hughes Reef, Gaven Reef (North), and Subi Reef, in light of the evidence relating to thelarger-scale island-building activities at those features which had not been available at the timeof the Memorial.1084 The Tribunal recognised that the amendments were related to, or incidental
to the Submissions originally made by the Philippines, and did not involve the introduction of a
new dispute between the Parties.1085 Indeed, the Philippines had already presented evidence ofChina’s gradually increasing construction activities at all seven reefs,1086 and had already set
forth its concerns over the resultant degradation of the marine environment.1087

The South China Sea Arbitration
Award of 12 July 2016934. It thus remains for the Tribunal to decide whether its jurisdiction over the Philippines’
Submissions No. 11 and 12(b) is constrained by the military activities exception in
Article 298(1)(b) of the Convention.
935. In determining whether Chinese land reclamation activities at the seven reefs are military innature, the Tribunal takes note of China’s repeated statements that its installations andisland-building activities are intended to fulfil civilian purposes.
936. On 9 September 2014, a Chinese Foreign Ministry Spokesperson stated that “the construction
work China is undertaking on relevant islands is mainly for the purpose of improving theworking and living conditions of people stationed on these islands.”1088 The same spokesperson
elaborated, in April 2015, that the “main purposes” of the “maintenance and construction work”
on the Spratly islands and reefs were:
optimizing their functions, improving the living and working conditions of personnel
stationed there, better safeguarding territorial sovereignty and maritime rights and interests,
as well as better performing China’s international responsibility and obligation in maritime
search and rescue, disaster prevention and mitigation, marine science and research,meteorological observation, environmental protection, navigation safety, fishery production
service and other areas.1089

937. These same civilian purposes were articulated on 12 June 2015, by the Head of China’sdelegation to the Meeting of States Parties to the UN Convention on the Law of the Sea.1090 As
noted below with respect to Submission No. 12, China’s President Xi Jinping stated in
September 2015 that “[r]elevant construction activities that China [is] undertaking in the islandof South -- Nansha Islands do not target or impact any country, and China does not intend to
pursue militarization.”1091

938. The Tribunal will not deem activities to be military in nature when China itself has consistently
and officially resisted such classifications and affirmed the opposite at the highest levels.
Accordingly, the Tribunal accepts China’s repeatedly affirmed position that civilian use
compromises the primary (if not the only) motivation underlying the extensive construction
activities on the seven reefs in the Spratly Islands. As civilian activity, the Tribunal notes that
China’s conduct falls outside the scope of Article 298(1)(b) and concludes that it has
jurisdiction to consider the Philippines’ Submissions No. 11 and 12(b).
(b)

Relevant Provisions of the Convention

939. The protection and preservation of the marine environment form a prominent component of thelegal regime of the Convention, the importance of which is recognised in the Preamble in thefollowing terms:
Recognizing the desirability of establishing through this Convention, with due regard forthe sovereignty of all States, a legal order for the seas and oceans which will facilitate
international communication, and will promote the peaceful uses of the seas and oceans, theequitable and efficient utilization of their resources, the conservation of their living
resources, and the study, protection and preservation of the marine environment . . .

940. The substantive provisions relevant to the marine environment comprise their own Part XII of
the Convention. At the outset, the Tribunal notes that the obligations in Part XII apply to all
States with respect to the marine environment in all maritime areas, both inside the national
jurisdiction of States and beyond it.1092 Accordingly, questions of sovereignty are irrelevant tothe application of Part XII of the Convention. The Tribunal’s findings in this Chapter have no
bearing upon, and are not in any way dependent upon, which State is sovereign over features in
the South China Sea.
941. Article 192 of the Convention provides that “States have the obligation to protect and preserve
the marine environment.” Although phrased in general terms, the Tribunal considers it wellestablished that Article 192 does impose a duty on States Parties,1093 the content of which isinformed by the other provisions of Part XII and other applicable rules of international law.
This “general obligation” extends both to “protection” of the marine environment from futuredamage and “preservation” in the sense of maintaining or improving its present condition.
Article 192 thus entails the positive obligation to take active measures to protect and preserve
1092

373

Award of 12 July 2016

the marine environment, and by logical implication, entails the negative obligation not todegrade the marine environment. The corpus of international law relating to the environment,
which informs the content of the general obligation in Article 192, requires that States “ensurethat activities within their jurisdiction and control respect the environment of other States or ofareas beyond national control.”1094 Thus States have a positive “‘duty to prevent, or at least
mitigate’ significant harm to the environment when pursuing large-scale construction
activities.”1095 The Tribunal considers this duty informs the scope of the general obligation in
Article 192.
942. The content of the general obligation in Article 192 is further detailed in the subsequent
provisions of Part XII, including Article 194, as well as by reference to specific obligations set
out in other international agreements, as envisaged in Article 237 of the Convention.1096
943. Article 194 concerns “pollution of the marine environment,” a term which is defined in Article 1of the Convention to mean “the introduction by man, directly or indirectly, of substances . . .
into the marine environment . . . which results or is likely to result in such deleterious effects asharm to living resources and marine life . . . [and] hindrance to . . . legitimate uses of thesea . . . .” The “measures to prevent, reduce and control pollution of the marine environment”
are set out in Article 194:
Article 194
Measures to prevent, reduce and control pollution of the marine environment
1.

States shall take, individually or jointly as appropriate, all measures consistent withthis Convention that are necessary to prevent, reduce and control pollution of themarine environment from any source, using for this purpose the best practicablemeans at their disposal and in accordance with their capabilities, and they shallendeavour to harmonize their policies in this connection.

States under special conventions and agreements concluded previously which relate to theprotection and preservation of the marine environment and to agreements which may beconcluded in furtherance of the general principles set forth in this Convention.

2.

Specific obligations assumed by States under special conventions with respect to theprotection and preservation of the marine environment, should be carried out in a mannerconsistent with the general principles and objectives of this Convention.

Award of 12 July 20162.

States shall take all measures necessary to ensure that activities under theirjurisdiction or control are so conducted as not to cause damage by pollution to otherStates and their environment, and that pollution arising from incidents or activities
under their jurisdiction or control does not spread beyond the areas where they

3.

The measures taken pursuant to this Part shall deal with all sources of pollution of
the marine environment. These measures shall include, inter alia, those designed tominimize to the fullest possible extent:(a)the release of toxic, harmful or noxious substances, especially those which
are persistent, from land-based sources, from or through the atmosphere or by

...
5.

The measures taken in accordance with this Part shall include those necessary toprotect and preserve rare or fragile ecosystems as well as the habitat of depleted,threatened or endangered species and other forms of marine life.

944. Articles 192 and 194 set forth obligations not only in relation to activities directly taken by
States and their organs, but also in relation to ensuring activities within their jurisdiction andcontrol do not harm the marine environment.

The Fisheries Advisory Opinion of theInternational Tribunal for the Law of the Sea sheds light on the obligation of a flag State toensure its fishing vessels not be involved in activities which will undermine a flag State’s
responsibilities under the Convention in respect of the conservation of living resources and theobligation to protect and preserve the marine environment. 1097 Drawing on decisions of theInternational Court of Justice in Pulp Mills on the River Uruguay1098 and the Seabed Disputes
Chamber advisory opinion,1099 the International Tribunal for the Law of the Sea noted that the
obligation to ‘ensure’ is an obligation of conduct. It requires “due diligence” in the sense of aflag State not only adopting appropriate rules and measures, but also a “certain level of

Award of 12 July 2016vigilance in their enforcement and the exercise of administrative control.” 1100 Upon receipt
from another State of reports of non-compliance, the flag State “is then under an obligation toinvestigate the matter and, if appropriate, take any action necessary to remedy the situation as
well as inform the reporting State of that action.”1101
945. The fifth paragraph of Article 194 covers all measures under Part XII of the Convention(whether taken by States or those acting under their jurisdiction and control) that are necessary
to protect and preserve “rare or fragile ecosystems” as well as the habitats of endangered
species.

As observed by the tribunal in Chagos Marine Protected Area, the phrasing of

Article 194(5) confirms that Part XII is “not limited to measures aimed strictly at controlling
marine pollution,” which while “certainly an important aspect of environmental protection . . . isby no means the only one.” 1102 An ‘ecosystem’ is not defined in the Convention, butinternationally accepted definitions include that in Article 2 of the CBD, which defines
ecosystem to mean “a dynamic complex of plant, animal and micro-organism communities andtheir non-living environment interacting as a functional unit.”1103 The Tribunal has no doubt
from the scientific evidence before it that the marine environments where the allegedly harmful
activities took place in the present dispute constitute “rare or fragile ecosystems.” 1104 They arealso the habitats of “depleted, threatened or endangered species,” including the giant clam, thehawksbill turtle and certain species of coral and fish.1105
946. Part XII of the Convention also includes Article 197 on cooperation, which requires States tocooperate on a global or regional basis, “directly or through competent internationalorganizations, in formulating and elaborating international rules, standards and recommended
practices and procedures consistent with this Convention, for the protection and preservation of
the marine environment, taking into account characteristic regional features.” In its provisional
measures order in MOX Plant, the International Tribunal for the Law of the Sea emphasised that“the duty to cooperate is a fundamental principle in the prevention of pollution of the marine

Award of 12 July 2016environment under Part XII of the Convention and general international law.”1106 Related toregional cooperation is the provision in Article 123 of the Convention, which covers semienclosed seas, such as the South China Sea:
Article 123
Cooperation of States bordering enclosed or semi-enclosed seas
States bordering an enclosed or semi-enclosed sea should cooperate with each other in theexercise of their rights and in the performance of their duties under this Convention. To thisend they shall endeavour, directly or through an appropriate regional organization:(a)to coordinate the management, conservation, exploration and exploitation of theliving resources of the sea;(b)

to coordinate the implementation of their rights and duties with respect to theprotection and preservation of the marine environment;(c)to coordinate their scientific research policies and undertake where appropriate joint
programmes of scientific research in the area;(d)to invite, as appropriate, other interested States or international organizations tocooperate with them in furtherance of the provisions of this article.

947. The final provisions of Part XII relevant to the Philippines’ Submissions concern monitoringand environmental assessment. Article 204 requires States to endeavour as far as practicable to“observe, measure, evaluate and analyse . . . the risks or effects of pollution on the marine
environment” and to keep under surveillance the effects of any activities which they “permit orin which they engage” in order to determine whether they are likely to pollute the marine
environment. Article 205 requires State to publish reports of the results from such monitoring
to the competent international organisations, which should make them available to all States.
Finally, Article 206 relates to environmental impact assessments:
Article 206
Assessment of potential effects of activities
When States have reasonable grounds for believing that planned activities under theirjurisdiction or control may cause substantial pollution of or significant and harmful changes
to the marine environment, they shall, as far as practicable, assess the potential effects ofsuch activities on the marine environment and shall communicate reports of the results ofsuch assessments in the manner provided in article 205.

948. Article 206 ensures that planned activities with potentially damaging effects may be effectively
controlled and that other States are kept informed of their potential risks.

In respect ofArticle 206, the International Tribunal for the Law of the Sea emphasised that “the obligation to

Harvesting of Vulnerable, Threatened and Endangered Species

950. Based on contemporaneous reports of naval, coastguard and fisheries authorities, diplomatic
exchanges and photographic evidence presented in the record, the Tribunal is satisfied that
Chinese fishing vessels have been involved in harvesting of threatened or endangered species on
the following occasions at or in the waters of Scarborough Shoal:(a)

In January and March 1998, Chinese fishermen were found in possession of corals andmarine turtles.1109(b)

In April 2000, Chinese fishing vessels were found with four tons of corals on board.1110(c)

In January 2001, Chinese fishing vessels were found with endangered sea turtles, sharks,
and corals.1111

Photographs from the incident show the harvesting of giant claims.1119
952. Recent evidence also indicates the large-scale harvest of endangered hawksbill sea turtles by
Chinese fishermen, whose arrest by Philippine authorities led to protests by China.1120
953. Finally, in addition to the occurrence of the above events recounted in the Philippines’
Memorial, the Tribunal is satisfied based on its review of satellite imagery, photographic andvideo evidence, contemporaneous press reports, scientific studies and the materials from
Professor McManus, that in recent years, Chinese fishing vessels have been engaged inwidespread harvesting of giant clams through the use of boat propellers to break through thecoral substrate in search of buried clam shells.
954. The Tribunal turns now to the harmful impact of the above-described activities and thenaddresses the extent to which China may be held responsible for breach of the Convention inconnection with those activities.
955. Many of the above-listed incidents involved the harvesting of coral species. The Ferse Report
describes the impact on the marine environment from the harvesting of coral as follows:
stony corals are frequently harvested as construction material, or for sale in the curio trade,e.g. to tourists. The repeated, targeted removal of coral colonies can modify the community
structure – branching species are preferably targeted for the curio trade, and their removal
leads to an overall loss of structural complexity. Decreased live coral cover and structuralcomplexity severely affects the reef fish community, as a large proportion of the species on
the reef utilise live corals at some point in their life history. 1121

956. All of the sea turtles (Cheloniidae) found on board Chinese fishing vessels are listed under
Appendix I to the CITES Convention as species threatened with extinction and subject to thestrictest level of international controls on trade. 1122 CITES is the subject of nearly universal
adherence, including by the Philippines and China, and in the Tribunal’s view forms part of thegeneral corpus of international law that informs the content of Article 192 and 194(5) of the1118

Convention.

“[T]he conservation of the living resources of the sea is an element in theprotection and preservation of the marine environment,”1123 and the Tribunal considers that thegeneral obligation to “protect and preserve the marine environment” in Article 192 includes adue diligence obligation to prevent the harvesting of species that are recognised internationallyas being at risk of extinction and requiring international protection.
957. The Tribunal is particularly troubled by the evidence with respect to giant clams, tons of whichwere harvested by Chinese fishing vessels from Scarborough Shoal, and in recent years,
elsewhere in the Spratly Islands. Giant clams (Tridacnidae) and many of the corals found in the
Spratly Islands are listed in Appendix II to CITES and are unequivocally threatened, even if
they are not subject to the same level of international controls as Appendix I species. Equallyimportant, however, giant clams play a significant role in the overall growth and maintenance ofthe reef structure.1124 The Ferse Report describes the effects of harvesting them as follows:
Giant clams have historically been harvested widely throughout Southeast Asia andbeyond, both for their meat and their shells. The larger species can reach considerable sizes(the largest species, Tridacna gigas, can reach almost 1.5m in size and a weight of over
300kg), but they grow slowly. Thus, large individuals have become rare on most reefs. As
their shells are highly coveted, collectors have begun to target fossil shells buried in the reef
flat (the shallow, extensive habitat on top of reefs). Excavation is highly destructive, withearly reports showing a drop in coral cover by 95% from its original value. More recently,
fishermen in the South China Sea are reported to utilise the propellers of their boats to
excavate shells from reef flats in the Spratly Islands on an industrial scale, leading to nearcomplete destruction of the affected reef areas.1125

958. The Tribunal recalls in particular the very recent examinations conducted by Professor
McManus, which led him to estimate that China is responsible for almost 70 square kilometresof coral reef damage from giant clam harvesting using propellers,1126 a practice he described as
more thoroughly damaging to marine life than anything he had seen in four decades ofinvestigating coral reef degradation.1127
959. The Tribunal has noted that it considers the duty to prevent the harvest of endangered species
follows from Article 192, read against the background of other applicable international law.
The Tribunal considers that this general obligation is given particular shape in the context offragile ecosystems by Article 194(5). Read in this context, the Tribunal thus considers that
Article 192 imposes a due diligence obligation to take those measures “necessary to protect and1123

preserve rare or fragile ecosystems as well as the habitat of depleted, threatened or endangered
species and other forms of marine life.”

Therefore, in addition to preventing the direct

harvesting of species recognised internationally as being threatened with extinction, Article 192
extends to the prevention of harms that would affect depleted, threatened, or endangered species
indirectly through the destruction of their habitat.
960. The Tribunal thus considers the harvesting of sea turtles, species threatened with extinction, toconstitute a harm to the marine environment as such. The Tribunal further has no doubt that theharvesting of corals and giant clams from the waters surrounding Scarborough Shoal andfeatures in the Spratly Islands, on the scale that appears in the record before it, has a harmful
impact on the fragile marine environment. The Tribunal therefore considers that a failure to
take measures to prevent these practices would constitute a breach of Articles 192 and 194(5) of
the Convention, and turns now to consider China’s responsibility for such breaches.
961. The vessels involved in the incidents described above were all Chinese flag vessels, under thejurisdiction and control of China. In the Tribunal’s view, where a State is aware that vessels
flying its flag are engaged in the harvest of species recognised internationally as being
threatened with extinction or are inflicting significant damage on rare or fragile ecosystems or
the habitat of depleted, threatened, or endangered species, its obligations under the Convention
include a duty to adopt rules and measures to prevent such acts and to maintain a level ofvigilance in enforcing those rules and measures.
962. On the question of awareness, it is clear from the record that the Philippines had brought its
concerns about poaching of endangered species to the attention of China as early as January
2000, when it stated to the Chinese Embassy that unlawful harvesting “disturbed the tranquillityof the ecosystem and habitat of important species of marine life and . . . caused irreparable
damage to the marine environment of the area.” 1128 The Philippines also recalled that thegathering and trade of corals violates the provisions of three international conventions to which
China is a signatory, including the CBD and CITES. In 2001, China assured the Philippinesthat it “attaches great importance to environmental protection and violators are dealt with inaccordance with Chinese laws and regulations.”1129 After finding 16 tons of clams and corals

aboard Chinese fishing vessels in 2005, the Philippines expressed its grave concern to China
over the “rampant trading of endangered corals and marine species in the South China Sea.”1130
963. China was therefore, certainly by 2005, on notice of poaching practices of Chinese fishingvessels in Scarborough Shoal and aware of the Philippines’ concerns. The poaching, however,has persisted, despite (a) China’s earlier statements that it would deal with violators, (b) China
being party to CITES since 1981, and (c) China having enacted in 1989 a Law of the Protectionof Wildlife, which prohibits the catching or killing of two classes of special state protectedwildlife,1131 and specifically lists among them sea turtles and giant clams.1132
964. As the Tribunal has noted above, adopting appropriate rules and measures to prohibit a harmful
practice is only one component of the due diligence required by States pursuant to the generalobligation of Article 192, read in the context of Article 194(5) and the international law
applicable to endangered species. There is no evidence in the record that would indicate that
China has taken any steps to enforce those rules and measures against fishermen engaged inpoaching of endangered species. Indeed, at least with respect to the April 2012 incidents, theevidence points directly to the contrary. China was aware of the harvesting of giant clams. It
did not merely turn a blind eye to this practice. Rather, it provided armed government vessels toprotect the fishing boats.1133 The Chinese Ministry of Foreign Affairs Spokesperson confirmed
on 12 April 2012 that it had “dispatched administrative vessels . . . to protect the safety andlegitimate fishing activities of Chinese fishermen and fishing vessels.”1134 Despite the reference

to “legitimate fishing activities”, the photographic evidence of endangered species, including
giant clams and sharks, on board the vessels in question indicates China must have known of,and deliberately tolerated, and protected the harmful acts.

Similarly, with respect to the

May 2013 incident in the vicinity of Second Thomas Shoal, the Tribunal accepts, on the basis of
the photographic and contemporaneous documentary evidence, that Chinese naval and CMS
vessels were escorting Chinese fishing vessels in gathering clams.1135 The Tribunal therefore
has no hesitation in finding that China breached its obligations under Articles 192 and 194(5) of
the Convention, to take necessary measures to protect and preserve the marine environment,with respect to the harvesting of endangered species from the fragile ecosystems at ScarboroughShoal and Second Thomas Shoal.
965. There remains the question of China’s responsibility for the more recent and widespreadenvironmental degradation caused by propeller chopping for giant clams across the Spratlys.
From satellite imagery showing scarring from this practice, it appears the harvesting took placein areas under control of Chinese authorities, at a time and in locations where Chinese
authorities were engaged in planning and implementing China’s island-building activities. The
Tribunal considers that the small propeller vessels involved in harvesting the giant clams were
within China’s jurisdiction and control. The Tribunal finds that China, despite its rules on theprotection of giant clams, and on the preservation of the coral reef environment generally, 1136
was fully aware of the practice and has actively tolerated it as a means to exploit the living
resources of the reefs in the months prior to those reefs succumbing to the near permanent
destruction brought about by the island-building activities discussed in Section 4.1137
966. Accordingly, the Tribunal finds that China has also breached its obligation to protect andpreserve the marine environment in respect of its toleration and protection of the harvesting of
giant clams by the propeller chopping method.

Use of Cyanide and Dynamite

967. The Tribunal next examines the complaints that China has breached the Convention in relation
to Chinese fishermen who used cyanide and explosives at Scarborough Shoal and Second
Thomas Shoal.
968. Based on contemporaneous reports from the Philippine navy, coast guard, and police, andphotographic evidence presented in the record, the Tribunal is satisfied that Chinese fishingvessels were engaged in the use of dynamite or cyanide on the following occasions:(a)

As early as 1995, 62 Chinese fishermen in the Spratly Islands were arrested byPhilippine authorities after being found in possession of explosives and cyanide.1138(b)

In March 1998, 29 Chinese fishermen at Scarborough Shoal were found inpossession of dynamite and convicted under Philippine fisheries law banning it.1139(c)

In April 2000, three Chinese vessels were found at Scarborough Shoal withblasting caps, detonating cord, and dynamite.1140(d)

On three occasions in 2002 Chinese vessels in Scarborough Shoal were found withblasting caps, detonating cord, plastic explosives, cyanide, and cyanide tubes.1141(e)

Cyanide pumps were found aboard Chinese vessels at Scarborough Shoal in
December 20051142 and April 2006.1143

969. After 2006, the only mention in the record of use by Chinese fishing vessels of explosives is ahistorical entry in a military briefing of May 2013, which recounts that on 12 February 2012
“2 fishing vessels believed to be Chinese were monitored fishing using explosives and sodium
cyanide 4 NM SW off LT57 in Ayungin Shoal.”1144 The Tribunal notes that this reference is
uncertain as to the provenance of the vessels and, unlike the above-listed incidents, isunsupported by contemporaneous reports, inventories, and photographs.

Accordingly, theTribunal does not include this incident in its further consideration of breach of Part XII of theConvention.
970. The Tribunal accepts the observation in the Ferse Report that cyanide and blast fishing are“highly destructive methods” that have been used in the Spratly Islands in the past decades. 1145
It takes note of the studies referred to by Professor Carpenter which found “both dynamite andcyanide fishing . . . among the most highly destructive of all fishing methods” and that bothmethods are considered irresponsible and unsustainable according to the FAO Code of Conduct
for Responsible Fisheries.1146 Because explosives shatter coral and cyanide can kill or injure
non-target species, the Tribunal considers the use of both dynamite and cyanide to be“pollution” of the marine environment within the meaning of the Convention—they aresubstances introduced by man that “result in such deleterious effects as to harm living resources
and marine life.”1147 They also threaten the fragile ecosystem of the coral reefs and the habitats
of endangered species at Scarborough Shoal. The Tribunal therefore considers that failure to
take measures against the use of dynamite and cyanide would constitute breach of Articles 192,
194(2) and 194(5) of the Convention.
971. The Tribunal must, however, address whether there is sufficient evidence that China should beheld responsible now for the failure to prevent the incidents listed in paragraph 968 above. The
Tribunal recalls that while Chinese fishing vessels are within China’s jurisdiction and control as
the flag State, the obligation to ensure that those fishing vessels do not take measures to pollute
the marine environment is one of due diligence.

972. In contrast to the poaching of endangered species, there is little evidence in the record withrespect to Philippine complaints to China about the use of cyanide and blasting specifically. Ina memorandum about a meeting with China’s Assistant Foreign Minister in April 1995, thePhilippine Ambassador in Beijing recorded raising the issue of 62 Chinese fishermen found inpossession of explosives and cyanide. He noted that this is “harmful to the marine environment
and thus, illegal. When coral reefs are destroyed, it takes generations before they can be rebuilt.
And the poisoning of the marine environment . . . is a matter of grave concern to the Philippine
Government.”1148
973. The Tribunal notes that the above statement pre-dates the introduction in 1999 of the Marine
Environment Protection Law of the People’s Republic of China.1149 Indeed in March 2000, thesame Philippine Ambassador to Beijing reported that a Chinese diplomat had expressed to him
her “particular concern about the practice of dynamite fishing” and had requested the Ministryof Agriculture to do something about the situation. 1150 A year later, the new Philippine
Ambassador in Beijing recalled that “local fishing authorities imposed a penalty on thefishermen caught blasting coral reefs near Scarborough Shoal in early 2000.” He was also told
by a Chinese Foreign Ministry official that “the Chinese Government attaches great importanceto environmental protection and violators are dealt with in accordance with Chinese laws andregulations.”1151
974. In 2000, the People’s Republic of China updated its Fisheries Law, Article 30 of which
prohibits the “use of explosives, poisons, electricity and any other means in fishing that impairs
the fishery resources.”1152 Adopting appropriate rules and measures is one component of thedue diligence required by States under the Convention. States are also required to adopt acertain level of vigilance in the enforcement and control of the rules, but there is little in therecord to suggest that China has failed to do so with respect to dynamite and cyanide fishing.

975. In contrast to the situations of harvesting of endangered species and harmful construction
activities, there is scant evidence in the case record about the use of explosives and cyanide overthe last decade or Philippine complaints about its use. This suggests China may have taken
measures to prevent such practices in the Spratly Islands. In any event, the Tribunal is notprepared to make a finding on the evidence available, under Submission No. 11 with respect tocyanide and explosives.
(d)

China’s Construction Activities on Seven Reefs in the Spratly Islandsi.

China’s Construction Activities and the Obligation to Protect and Preserve
the Marine Environment

976. The Tribunal turns now to the environmental impact of China’s extensive island-building
project at seven reefs in the Spratly Islands, the nature and extent of which is described inparagraphs 852 to 890 above. In summary, the record shows that since the end of 2013, China
has created on top of the coral reefs approximately 12.8 million square metres of land, frommillions of tons of dredged coral, rocks and sand. There is no question that the artificial
island-building program is part of an official Chinese policy and program implemented byorgans of the Chinese State.
977. Before turning to the impact of China’s recent island-building activities, the Tribunal recallsthat during the preceding two decades, China, as well as the Philippines and other States in theregion, undertook some more modest construction and land reclamation work on features in the
Spratly Islands, which has included the installation of buildings, wharves, helipads, and weather
and communications instruments.1153 The Tribunal notes Professor Carpenter’s observation thatmost of the construction during this period was “limited to building discrete structures with aminimal footprint on the natural form and structure of existing coral reefs.”1154 Nevertheless, heopined in his first report that the earlier generation of concrete structures (including those built
by other States) reduced the coral reefs on which they were installed, displaced the organismsthat inhabited them, and made the reefs’ structural integrity vulnerable to wave action and

The South China Sea Arbitration
Award of 12 July 2016storms.1155 Human presence on the features also entails the disposal of waste, and waste water,which promotes algal growth that can detrimentally affect fisheries.1156 The Ferse Report also
acknowledged that while the Spratly Islands are an area of high diversity and among the least
impacted reefs in the South China Sea, the “area is not pristine” and had already been affectedby the impacts of human activity, such as overfishing and destructive fishing, construction
activities and human habitation “for several decades prior to commencement of large-scaleconstruction in 2013.” 1157 The Ferse Report concluded however, that “[t]he scale of theseprevious impacts generally cannot be compared with the environmental harm caused by theconstruction activities, both in terms of spatial extent and duration.”1158
978. The conclusions of the Tribunal-appointed independent experts are unequivocal with respect tothe more recent construction activities, which they say have “impacted reefs on a scale
unprecedented in the region.”1159 They cite a 2016 study analysing satellite imagery that foundup to 60 percent of the shallow reef habitat at the seven reefs has been directly destroyed.1160
Construction-related sedimentation and turbidity have affected large portions of the reefs
beyond the immediate area of construction. The Ferse Report states:
The effects of these impacts on the reefs, together with altered hydrodynamics and released
nutrients, are likely to have wide-ranging and long-lasting ecological consequences for theaffected reefs and the wider ecosystem of the Spratly Islands, and possibly beyond. Reefs
subjected to direct land reclamation have disappeared entirely. Reefs subjected to dredging
in order to create landfill will have lost their complex structure that was built over centuries
to millennia. This structure will take decades to centuries to recover. Reefs that did notexperience dredging directly but were impacted by the associated sedimentation andnutrient release will likely have experienced severe coral mortality and recovery will takeplace more slowly than in natural settings, likely taking decades. The capacity for
ongoing . . . carbonate production is severely diminished on several of the reefs, and theircapacity to keep up with increasing sea level rise is impaired. 1161

979. The Tribunal accepts the conclusion in the Ferse Report that “China’s recent construction
activities have and will cause environmental harm to coral reefs at Cuarteron Reef, Fiery Cross
Reef, Gaven Reef, Johnson Reef, Hughes Reef, Mischief Reef, and Subi Reef; beyond thepre-existing damage to reefs that resulted from destructive fishing and the collection of corals
and clams, storm damage, Crown-of-Thorns starfish, and the human presence on small garrisons

on the reefs.” The Ferse Report also arrives at the following conclusions as to the extent andlikely duration of the harm.
•

The harm caused by direct burial of reef habitat during the construction of artificial islands
is near-permanent. The duration of harm to areas affected by dredging and dredgingrelated release of sediments and nutrients and the prospects and likely rates for rejuvenationdiffer depending on the environmental setting of each particular affected habitat area. We
expect that the harm to areas affected by dredging for navigable channels and basins will
likely be near-permanent and that the prospects for rejuvenation are low, particularly as
long as maintenance dredging for the use of the artificial islands continues. Second, where
major geomorphological structures have been removed through dredging, such as large
coral ‘bommies’ (accumulations of corals that typically stand several metres above thesubstrate), there is little prospect for recovery on ecological time scales. These structures
constitute accumulated reef growth on geological time scales of centuries to millennia.
This statement applies to much of the lagoon and deeper parts of the reef flat where thesefeatures (bommies or patch reefs) have been described in the Spratly Islands. Harm toareas affected by smothering of sediments and increased turbidity, which includes most of
the lagoons at Mischief and Subi Reefs and parts of the outer reef slopes of all seven reefs,
is likely to endure for years to decades within the lagoons (due to limited water exchange),
and for weeks to months on the outer reef slopes. Rejuvenation of these areas is possible(provided chronic stressors such as sedimentation are removed and recurrent stressors suchas bleaching events are infrequent), but will take several decades, and it will likely takecenturies for large massive colonies to regrow.

•

China’s construction activities have led to reduced productivity and complexity of theaffected reefs, with significant reductions of nursery habitat for a number of fish species.
Therefore, not only will the reefs affected by construction have a greatly reduced capacity
to sustain local fisheries but their ability to help replenish the fisheries of neighbouring
jurisdictions will also be vastly diminished – at least threefold. The construction activities
thus will have a broader impact on the marine ecosystem in and around the South China
Sea and on fisheries resources. However, the magnitude of this impact will depend on therelative role of the seven affected reefs as critical habitat and source of larvae for fisheries
resources compared to other reefs in the Spratly Islands, which is difficult to quantify due
to a lack of empirical studies. On the basis of available information, cascading effects
cannot be ruled out.1162

980. The conclusions in the Ferse Report largely confirm the conclusions reached in the First andSecond Carpenter Reports. However, Dr. Ferse and his colleagues noted in Part IX of theirreport, that in some respects they consider Professor Carpenter may have overstated orunderstated particular aspects of the damage.1163
981. The Tribunal is conscious that the conclusions reached in the Ferse Report and those byProfessor Carpenter and in other recent scientific studies,1164 are at odds with China’s statedposition that its construction activities have followed a “high standard of environmental
protection” and that the marine environment end ecosystem of the South China Sea “will not be

damaged.”1165 The Tribunal has accordingly sought out China’s position on the environmental
impact of its construction activities, by reviewing statements of Chinese officials and scientists,
by asking the Philippines and the Tribunal-appointed experts to locate and assess the claims by
Chinese officials and scientists, and by directly requesting China to comment on a range ofmaterials and questions about the alleged impact of the construction.
982. The Ferse Report noted that several ecological studies of the area by Chinese researchers
actually emphasise the need for conservation of the seven reefs,1166 and “available satellite andaerial imagery provides little indication of effective mitigation measures.”1167 As to the generalclaim that the construction activity “does not damage the environment on the reefs,” the Ferse
Report stated it “is contradicted by the facts.”1168 While the Ferse Report noted that the Chinesestatements contained “accurate descriptions of the environmental conditions at the reefs,” theChinese assessments of the nature and extent of impacts from construction were “largely indisagreement with the available information.”1169 The following are examples of specific claims
made by Chinese scientists that were addressed in the Ferse Report:(a)Replenishment: Chinese scientists claimed that in the South China Sea “the nutrients andfood organisms can be replenished constantly from surrounding waters.” The Ferse
Report noted there is “very limited support” for the potential for replenishment fromoutside the Spratly Islands, in light of larval connectivity patterns within the South China
Sea.1170(b)Timing of works: In relation to the claim by Chinese scientists that the construction wastimed “reasonably, trying to avoid spawn periods of red snapper (mid-April), tuna (peakfrom June to August) and bonito (from March to August),” the Ferse Report analysedsatellite and aerial imagery to conclude that land construction had indeed occurred in

months during those spawning periods. 1171 The Ferse Report noted that construction
activity occurred during the suspected spawning time of reef corals.
(c)Water quality: Chinese scientists claimed that China avoided “fine sands from going into
reclamation areas to maintain the water quality of coral reef areas.” The Ferse Reportstated that satellite and aerial imagery clearly shows water quality in the vicinity of eachconstruction site was affected by increased sediment and turbidity from dredging. 1172(d)

Restoration and Transplantation: Chinese scientists claimed that “the restoration of coral
reef communities could be realized should effective measures be taken” and that “coral
reefs that have been severely damaged . . . can be restored initially in 5-10 years provided
that effective measures are taken, and complex and complete ecosystems can be fully
restored in 50-100 years.”

They also suggested implementing measures like“transplantation” to better protect the coral reefs.

The Ferse Report explained that

restoration is not likely to succeed if stressors persist and if ecological connectivity andlarval supply are disturbed. The Ferse Report noted the uncertainty of restoration science.
It further noted “large parts of the seven reefs have been permanently destroyed byconstruction, and for the remaining areas, recovery is uncertain and, if it occurs, it willtake more than a century until the large massive coral colonies have regrown.” Further,restorative activities are “extremely expensive” and have only ever been attempted on far
smaller scales. Transplantation is unlikely to be suitable on the scale of the impacts fromconstruction, as it could risk impacting other reefs in the region, and involves“prohibitive” labour and costs.1173(e)Impact on reef structure: Chinese scientists claimed that due to strong currents andwaves, “the photosynthesis of corals” was left “largely unaffected” and because the sites
are located in areas where coverage of coral reefs is low, “the overall community
structure of coral reefs” and the “physical and chemical living environment of coral reefs”
have not fundamentally changed. The Ferse Report pointed to the sediment plumes
generated by dredging and notes they are “very likely to have altered the community
structure of the affected coral reefs.” The Ferse Report recalled that the construction has
permanently altered the hydrodynamics of the affected reefs, and elevated level ofsediments are likely, “from months to years in those parts of the reefs that are1171

well-flushed by open ocean waters, and from years to decades in areas with less flushing,such as the lagoons of Mischief and Subi Reef.”1174(f)

Impact on reef health: Chinese scientists claimed that in light of the status of the reefs as“sub-healthy” both before and after the construction activities, it can be concluded thatthe “construction activities neither affected the health of the ecosystems of Nansha nor
harmed the coral reef ecosystems.”

The Ferse Report noted the lack of available

information on post-construction monitoring but recalls that “the available evidence
leaves little doubt that the coral reef ecosystems of the seven affected reefs have sufferedsignificant and extensive harm as a result of construction activities.” 1175(g)

Selection of sites containing dead coral: The SOA and other Chinese scientists claim thatthe construction sites contained dead coral. The Ferse Report noted that even deep
lagoon basins containing less live corals than other reef habitats constitute a vital habitat
for molluscs, echinoderms and crustaceans.

On the reefs lacking a deep lagoon(Cuarteron, Hughes, Gaven, and Johnson), material for land reclamation was gatheredfrom the shallow reef habitat. In any event, sediment plumes affected both lagoon andouter reef slope habitats.
(h)Use of “nature simulation” method: China embraces the “nature simulation” as its“comprehensive technical concept” in the Nansha reef expansion project. It claims theland reclamation area will “produce the ecological effects by going from desalination,solidification, efflorescence, to a green coral reef ecological environment.”1176 The Ferse
Report observed that this statement overlooks the importance of biogenic sedimentproduction.

“Rather than simulating the natural process of island development, theconstruction process increases the erosion of the reefs by shifting the balance between
carbonate accretion and erosion, and thus increases the risk of drowning the reef as sea
levels continue to rise.”1177(i)

Recovery: China’s SOA has claimed that “[g]ood results have been obtained and theecological impact on the coral reefs is partial, temporary, controllable, and1174

recoverable.” 1178 The Ferse Report summed up its responses to this and previous
statements as follows:
Ecological impacts from the construction activities affected large parts of the reefs
and include permanent (for reclaimed reef flats and excavated channels) and longlasting (for sediment resuspension in lagoons) effects. The extensive sedimentplumes visible from aerial and satellite imagery that remained near the construction
areas for several weeks to months render the amount of control over potential
impacts doubtful. For large areas of reef affected by the construction activities,
recovery is unlikely, or may take decades to centuries. 1179

983. Based on the compelling evidence, expert reports, and critical assessment of Chinese claims
described above, the Tribunal has no doubt that China’s artificial island-building activities on
the seven reefs in the Spratly Islands have caused devastating and long-lasting damage to themarine environment. The Tribunal accordingly finds that through its construction activities,
China has breached its obligation under Article 192 to protect and preserve the marine
environment, has conducted dredging in such a way as to pollute the marine environment withsediment in breach of Article 194(1), and has violated its duty under Article 194(5) to takemeasures necessary to protect and preserve rare or fragile ecosystems as well as the habitat ofdepleted, threatened or endangered species and other forms of marine life.
ii.

China’s Construction Activities and the Obligation to Cooperate

984. The Tribunal further notes that China’s construction activities at the seven coral reefs have been
met with protest from the Philippines and other neighbouring States. 1180 Article 197 of theConvention requires States to cooperate on a regional basis to formulate standards and practices
for the protection and preservation of the marine environment. In relation to semi-enclosed
seas, the Convention further specifies in Article 123 that States shall endeavour to coordinate
the implementation of their rights and duties with respect to the protection and preservation of
the marine environment.
985. The importance of cooperation to marine protection and preservation has been recognised by theInternational Tribunal for the Law of the Sea on multiple occasions.1181 The International Court

the plans initiated by one or [the] other of them, so as to prevent the damage in question.”1182
986. With respect to China’s island-building program, the Tribunal has before it no convincing
evidence of China attempting to cooperate or coordinate with the other States bordering theSouth China Sea. This lack of coordination is not unrelated to China’s lack of communication,
discussed below.
iii.

China’s Construction Activities and the Obligation to Monitor and Assess

987. Article 206 requires that when States have “reasonable grounds for believing that planned
activities under their jurisdiction or control may cause significant and harmful changes to themarine environment” they shall as far as practicable assess the potential effects of such activities
on the marine environment” and also “shall communicate reports of the results of suchassessments.”
988. The Tribunal considers that given the scale and impact of the island-building activities
described in this Chapter, China could not reasonably have held any belief other than that theconstruction “may cause significant and harmful changes to the marine environment.”
Accordingly, China was required, “as far as practicable” to prepare an environmental impact
assessment. It was also under an obligation to communicate the results of the assessment.
989. In Construction of a Road (Nicaragua v. Costa Rica), 1183 the International Court of Justicefound that Costa Rica’s simple assertions as to the existence of a preliminary assessment did notequate to having “adduced any evidence that it actually carried out such a preliminary
assessment.”1184 Despite China’s repeated assertions by officials at different levels, that it has

undertaken thorough environmental studies, neither the Tribunal, the Tribunal-appointed
experts, the Philippines, nor the Philippines’ experts have been able to identify any report thatwould resemble an environmental impact assessment that meets the requirements of Article 206of the Convention, or indeed under China’s own Environmental Impact Assessment Law of
2002.1185
990. By China’s own legislative standards, an EIA must be “objective, open and impartial,
comprehensively consider impacts on various environmental factors and the ecosystem they
form after the implementation of the plan or construction project, and thus provide scientificbasis for the decision-making.”1186 Additionally, the “state shall encourage all relevant units,
experts and the public to participate in the EIA in proper ways.” 1187

With respect toconstruction projects, Chinese law requires an EIA to include, inter alia, analysis, projectionand evaluation on the potential environmental impacts of the project, and suggestions on
implementation of environmental monitoring. 1188 The SOA Statement and the SOA Reportwhich the Tribunal did manage to locate both fall short of these criteria, and are far lesscomprehensive than EIAs reviewed by other international courts and tribunals, or those filed in
the foreign construction projects to which the SOA scientists referred in their report.1189
991. The Tribunal cannot make a definitive finding that China has prepared an environmental impact
assessment, but nor can it definitely find that it has failed to do so in light of the repeatedassertions by Chinese officials and scientists that China has undertaken thorough studies. Sucha finding, however, is not necessary in order to find a breach of Article 206. To fulfil theobligations of Article 206, a State must not only prepare an EIA but also must communicate it.
The Tribunal directly asked China for a copy of any EIA it had prepared; China did not provide
one. 1190 While acknowledging that China is not participating in the arbitration, China has

In any event,the obligation to communicate is, by the terms of Article 205, to “competent internationalorganizations, which should make them available to all States.”

Although China’s

representatives have assured the States parties to the Convention that its “construction activities
followed a high standard of environmental protection,” it has delivered no assessment in writing
to that forum or any other international body as far as the Tribunal is aware.1192 Accordingly,
the Tribunal finds that China has not fulfilled its duties under Article 206 of the Convention.

992. Based on the considerations outlined above, the Tribunal finds that China has, through its
toleration and protection of, and failure to prevent Chinese fishing vessels engaging in harmful
harvesting activities of endangered species at Scarborough Shoal, Second Thomas Shoal andother features in the Spratly Islands, breached Articles 192 and 194(5) of the Convention.
993. The Tribunal further finds that China has, through its island-building activities at Cuarteron
Reef, Fiery Cross Reef, Gaven Reef (North), Johnson Reef, Hughes Reef, Subi Reef andMischief Reef, breached Articles 192, 194(1), 194(5), 197, 123, and 206 of the Convention.

Mischief Reef and its construction there of installations and artificial islands. This dispute isreflected in parts (a) and (c) of the Philippines’ Submission No. 12, which provides as follows:(12)

Submission No. 12(b)—asserting that China has violated its “duties to protect and preserve themarine environment”—in connection with Submission No. 11 (at paragraphs 815 to 993 above).

2.

Factual Background(a)

China’s Initial Activities on Mischief Reef (1995 to 2013)996. Chinese construction activities on Mischief Reef reportedly date back at least to January 1995,
when fiberglass structures flying the Chinese flag were observed at four separate locations on
the reef platform.1193 Fishermen from the Philippines reported the presence of “an estimated1,000 uniformed men” aboard eleven Chinese vessels anchored there and in the structures on
the reef.1194
997. On 6 February 1995, the Philippines submitted an Aide Memoire1195 to the Chinese Ambassador
in Manila. According to Philippine records, China had denied1196 that it was building a base on
the feature. The Philippines expressed “serious concern” over Chinese activities on Mischief
Reef, including:

The Philippines added that China’s actions violated “the spirit of the 1992 ASEAN Declarationon the South China Sea” and requested the immediate removal of Chinese vessels from the reef.
998. On 10 March 1995, China’s Vice Premier and Minister of Foreign Affairs reportedly described
the structures on Mischief Reef as “typhoon shelters” constructed by Chinese fishing authorities“for the purpose of protecting the lives of Chinese fishermen and their production.”1198 The
Minister reiterated that the structures were civilian in nature and did “not pose threat to any
country.”1199
999. In the period from October 1998 to February 1999, China substantially enlarged two of thestructures on Mischief Reef while removing the other two.1200 On 15 October 1998, according
to Philippine diplomatic archives, China informed the Philippine Ambassador in Beijing of“plans to renovate and reinforce the structures it [China] constructed on Mischief Reef back in
1995.”1201 According to the Philippines’ then-Undersecretary for Policy in the Department of
Foreign Affairs, the Philippine Ambassador was informed by the Chinese Ministry of Foreign
Affairs that:
Chinese local fishing authorities will undertake “soon” the renovation and reinforcement
works which have become necessary because the structures have deteriorated over the years
due to exposure to the elements. Furthermore, the Chinese have stated that they will give
positive consideration to the use of the facilities by other countries, including thePhilippines, after the renovation and reinforcement works have been completed and when
the conditions are ripe.1202

1000. Philippine records indicate that, in addition to reinforcing two of the existing structures, China
added a concrete platform supporting a three-storey building at each site.1203 A report by the
Armed Forces of the Philippines described the construction activities as involving “[a]bout
100-150 personnel working on site laying foundations for rectangular structure.”1204
1001. On 5 November 1998, the Philippines sent China a Note Verbale in which it demanded from
China that it:
immediately cease and desist from doing further improvements over the illegal structures it
has built in [Mischief] Reef and to dismantle any repair works, renovations, reinforcements,
fortifications and/or improvements made therein.1205

1002. On 9 November 1998, the Philippine Ambassador in Beijing met the Deputy Director Generalof the Asia Department of the Chinese Ministry of Foreign Affairs. At the meeting, the Deputy
Director General characterised the activities as “the work of the local fishing authorities
undertaking repair and renovation.” 1206 On 14 November 1998, China’s Minister of Foreign
Affairs explained that “the structures are solely for shelter of fishermen . . . . The scale of work
is small and there is no change in the civilian nature of the facilities.”1207
1003. By February 1999, the two sites at Mischief Reef were equipped with a helipad, newcommunications equipment, and wharves.1208 An oblique photograph taken by the Philippinesand reproduced as Figure 30 on page 402 below depicts the smaller of China’s two structures

(b)Island-Building Activities on Mischief Reef (Post-2013)

1004. Construction on Mischief Reef between 1999 and 2013 appears to have been relatively limited.
China’s intensive construction of artificial islands on seven coral reefs commenced in 2014,
with construction on Mischief Reef resuming from January 2015. 1209 On 28 May 2015, forinstance, the Philippine Secretary of National Defense, identified “around 32 dredger vessels,
32 cargo ships and three (3) ocean tugs” deployed at the reef.1210
1005. On 3 February 2015, in response to the commencement of substantial construction on Mischief
Reef that year, the Philippines delivered to China a Note Verbale “to strongly protest China's
land reclamation activities at Panganiban (Mischief) Reef.” 1211 The Philippines went on toassert as follows:
Panganiban [Mischief] Reef is a low-tide elevation located in the exclusive economic zoneof the Philippines and on its continental shelf. Pursuant to Articles 60 and 80 of the 1982
United Nations Convention on the Law of the Sea (UNCLOS), the Philippines has the
exclusive right to authorize the construction of artificial islands, installations or other1209

structures in the vicinity of Panganiban [Mischief] Reef. China's reclamation activities
constitute a flagrant violation of these rights. 1212

The Philippines concluded by requesting that China “desist from its reclamation activities.”1213
1006. On 12 February 2015, China replied that “China has indisputable sovereignty over the Nansha
Islands and its adjacent waters. The development of any facility in the Nansha Islands falls
within the scope of China’s sovereignty.”1214
1007. Aerial and satellite photography up to and over the course of 2015 details China’s constructionof an artificial island on Mischief Reef and is reproduced at Figures 31 and 32 on page 405
below. The latter photograph from October 2015 shows an artificial island covering the entire
northern half of the reef.
1008. Calculations presented by the Philippines estimate that China’s construction work has resulted
in the creation of 5,580,000 square metres of new land on Mischief Reef as ofNovember 2015.1215
1009. China’s activities on Mischief Reef are not limited to the creation of new land alone. Chineseconstruction on the feature has added fortified seawalls, temporary loading piers, cement plants,
and a 250-metre-wide channel to allow transit into the lagoon by large vessels.1216 Additionally,
one analysis has noted that an area of approximately 3,000 metres in length has “been cleared
and flattened along the northern rim of the reef,”1217 a development that, according to media
reports, may indicate the intention to build an airstrip. 1218 A Chinese Foreign Ministry
Spokesperson was questioned regarding the construction of an airstrip on Mischief Reef and did
not deny this, noting instead that “[c]onstruction activities taken by the Chinese side on some1212

The Philippines’ Position

1010. The Philippines submits that China’s activities at Mischief Reef violate Articles 60 and 80 of
the Convention, relating to artificial islands, installations. and structures. and constituteunlawful acts of attempted appropriation under the Convention.
(a)Military Activities and the Tribunal’s Jurisdiction

1011. The Philippines submits that the Tribunal has jurisdiction to consider the matters raised in its
Submission No. 12, and that the Tribunal’s jurisdiction is not constrained by the exception for
military activities in Article 298(1)(b).1220
1012. The Philippines notes that China did not invoke the military activities exception in its Position
Paper of 7 December 2014.1221 In the Philippines’ view, the Tribunal should accept China’s
own characterisation of its activities. According to the Philippines, “[t]he decision by a State tocharacterise its own actions as military activities is not one that is taken lightly. The political,
legal and other consequences may extend well beyond Article 298, or indeed the Law of the Sea
Convention as a whole.” 1222 Far from China having invoked the exception, the Philippines
notes that “China repeatedly told the Philippines that the facilities at Mischief Reef were being
built for civilian use” and argues that any “fleeting intimation of a concurrent defence purpose
falls far short of a characterisation of the activities as military.” 1223 The Philippines also recallsthat China’s President Xi Jinping has stated that China does not intend to militarise thefeatures.1224

1013. According to the Philippines, “the context [of the military activities exception] requires that thenature and purpose of the activity be military, to the exclusion of other activities or purposesthat are more than purely incidental.” 1225 With this in mind, the Philippines argues that“mixed-use projects” and situations “in which a military unit is used to protect other activities”
are not covered by the exception to jurisdiction. 1226 With respect to land reclamation inparticular, the Philippines submits that “the involvement of military personnel in construction orland reclamation activities does not necessarily mean that the purpose of the activities ismilitary. The logistical capabilities of the armed forces are at times engaged for civilian
purposes in different parts of the world.”1227 The Philippines also notes that “[t]he Chinese
People’s Liberation Army is expressly tasked by the constitution to ‘participate in national
reconstruction’, and has an extensive record of civil projects.”1228
1014. Finally, the Philippines argues that subsequent Chinese statements cannot change the nature of
the activities it has undertaken. According to the Philippines, “[t]he nature of the activity
complained of is determined as of the time that activity occurred. The respondent cannot
thereafter unilaterally change the jurisdictional facts regarding its past conduct, especially
two-and-a-half years after the proceedings were commenced.”1229(b)

Articles 60 and 80 of the Convention

1015. The Philippines develops its Submissions from the position that Article 56(1) provides coastal
States the “exclusive right to regulate the establishment and use” of such structures within its
exclusive economic zone.1230 On this basis, the Philippines submits that China’s construction of
artificial islands, installations, and structures on Mischief Reef violate Articles 60 and 80 of theConvention.1231 Specifically, the Philippines argues that, under Article 60, coastal States enjoy
the “exclusive right” to authorise or regulate the construction of structures, a principle that is
extended to the continental shelf by virtue of Article 80.1232

1016. In this connection, the Philippines notes that Mischief Reef “is located within 200 M” of
Palawan and “not within 200 M of any other feature claimed by China that is capable ofgenerating an EEZ or a continental shelf.”1233 In its view, therefore, the Philippines remains the
only possible beneficiary of the effects of Articles 60 and 80 of the Convention with respect toMischief Reef.1234 Accordingly, because China did not “seek and receive authorization from thePhilippines,” 1235 it violated Articles 56(1)(b)(i), 60(1), and 80 of the Convention.1236 Because
the Philippines considers the Convention to require similar authorisation for the “operation anduse” of structures already built (in addition to their construction in the first instance), moreover,it submits that China’s violation is a “continuing” one, at least so long as its activities on
Mischief Reef persist.1237(c)Attempted Appropriation under the Convention

1017. The Philippines also considers China’s construction of artificial islands, installations, and otherstructures to constitute acts of attempted and unlawful appropriation.1238 Taking into account
China’s assertions of sovereignty over the reef, as well as the presence of China’s flag, thePhilippines considers that it is “beyond dispute” that China claims to have appropriatedMischief Reef.1239
1018. In the Philippines’ view, low-tide elevations are incapable of being “fully assimilated withislands or other land territory” such as to extend a State’s sovereignty over such features (seealso paragraphs 307 to 309 above). 1240 Drawing on guidance provided by the International
Court of Justice in Maritime Delimitation and Territorial Questions between Qatar and Bahrain
and Sovereignty over Pedra Branca/Pulau Batu Puteh, Middle Rocks and South Ledge(Malaysia/Singapore), the Philippines considers that “sovereignty and other rights” in relation
to low-tide elevations are determined “by the maritime zone in which they are located.”1241 As aresult, and to the extent such features lie within the territorial sea of an island or other land

considers Mischief Reef to lie within its exclusive economic zone and continental shelf, thePhilippines deems Mischief Reef to be “subject to [its] sovereign rights.”1243 Those rights, itsuggests, do not depend on occupation or express proclamation.1244
4.

China’s Position

1019. Although China is not participating in these proceedings, its statements relating to the natureand purpose of its actions at Mischief Reef provide an indication of China’s position regarding
its activities on the reef.
1020. In bilateral meetings from 20 to 21 March 1995, the Chinese Vice Minister for Foreign Affairs
informed his Philippine counterpart that the reef’s structures “are not military [structures], they
are wind shelters and Chinese fishermen have long used Mischief [Reef] as wind shelter.”1245
China reiterated its position throughout 1995.1246 During bilateral talks on 10 August 1995, forinstance, China emphasised the economic character of its activities and explained that theconstruction was intended to provide shelter for fishermen from local winds:
It is nothing serious for the Chinese side to construct some windsheltering facilities forpeaceful purposes. Some people just exaggerated this and they said that the Chinese side isconstructing a military facility. This does not square with the fact[s]. 1247

1021. Further statements by China have largely reflected its previous assertions as to the structures’purpose, continuing throughout the 1990s to characterise its activities on Mischief Reef ascivilian in nature.1248 On 15 March 1999, China informed the Philippines that the facilities were1242

“meant for civilian use and not for military purposes,” and stated that, “[b]y repairing thestructures, China’s actual intention to use them as fishermen shelters will be supported.” 1249
China explained, further, that the “so-called radar facilities” on the reef were “nothing but dishtype television satellite antennae to enable the personnel on the reef to watch ordinary TV
programs.”1250 At a bilateral meeting the following month, China reiterated that its facilities
would “remain for civilian purposes.”1251
1022. In keeping with its earlier pronouncements, more recent Chinese statements have continued tocharacterise China’s activities on Mischief Reef as intended for civilian purposes.

On

9 April 2015, for example, a Spokesperson for China’s Foreign Ministry stated:
The Chinese government has been carrying out maintenance and construction work onsome of the garrisoned Nansha Islands and reefs with the main purposes of optimizing theirfunctions, improving the living and working conditions of personnel stationed there, better
safeguarding territorial sovereignty and maritime rights and interests, as well as better
performing China’s international responsibility and obligation in marine search and rescue,disaster prevention and mitigation, marine science and research, meteorologicalobservation, environmental protection, navigation safety, fishery production service andother areas. The relevant construction, which is reasonable, justified and lawful, is wellwithin China’s sovereignty. It does not impact or target any country, and is thus beyond
reproach.
After the construction, the islands and reefs will be able to provide all-round andcomprehensive services to meet various civilian demands besides satisfying the need ofnecessary military defense. The maritime areas in the South China Sea, where shipping
lanes criss-cross and fishing grounds scatter around, are far away from the landmass. These
areas are prone to marine accidents due to the influence of typhoon and monsoon. Civilianfunctions and facilities will be included in the construction for ships to take shelter, and fornavigation aid, search and rescue, marine meteorological observation and forecast, fisheryservice and administration, so as to provide services to ships of China, neighboring
countries and other countries that sail across the South China Sea. 1252

1023. On 16 June 2015, China’s Foreign Ministry Spokesperson reiterated that “the main purpose of
China’s construction activities is to meet various civilian demands.” 1253 The statement was

The Tribunal’s Considerations(a)

The Tribunal’s Jurisdiction

1024. In its Award on Jurisdiction, the Tribunal held that Submission No. 12 reflects a disputeconcerning “China’s activities on Mischief Reef and their effects on the marine
environment.”1255 It determined that this is not a dispute concerning sovereignty or maritime
boundary delimitation, nor is it barred from the Tribunal’s consideration by any requirement of
Section 1 of Part XV.1256 The Tribunal warned, however, that its jurisdiction to address thequestions raised in Submission No. 12 “is dependent on the status of Mischief Reef as an‘island’, ‘rock’, or ‘low-tide elevation’.”1257 Had the Tribunal found—contrary to the premiseof the Philippines’ Submission—that Mischief Reef is a fully entitled island or rock and thus
constitutes land territory, it would necessarily lack jurisdiction to consider the lawfulness ofChina’s construction activities on Mischief Reef (at least in terms of the provisions of theConvention concerning artificial islands) or the appropriation of the feature.1258 Accordingly,
the Tribunal deferred taking any final decision with respect to its jurisdiction over thisSubmission.1259
1025. The Tribunal has now found, however, that Mischief Reef is a low-tide elevation and not a rockor fully entitled island (see paragraphs 374 to 378 above) and, as such, generates no entitlement
to maritime zones of its own. The Tribunal has also found that none of the high-tide features in
the Spratly Islands is a fully entitled island for the purposes of Article 121 of the Convention2015), available at <www.fmprc.gov.cn/mfa_eng/xwfw_665399/s2510_665401/t1273370.shtml>. The

The South China Sea Arbitration
Award of 12 July 2016(see paragraphs 473 to 647 above). From these conclusions, it follows that there exists no legal
basis for any entitlement by China to maritime zones in the area of Mischief Reef and nosituation of overlapping entitlements that would call for the application of Articles 15, 74, or 83
to delimit the overlap. Mischief Reef is necessarily a low-tide elevation located within the
exclusive economic zone of the Philippines.
1026. In its Award on Jurisdiction, the Tribunal also reserved for the merits the question of whether
Chinese activities at Mischief Reef constitute “military activities” within the scope of
Article 298(1)(b) of the Convention.1260 Article 298(1)(b) excludes disputes concerning militaryactivities from compulsory dispute settlement under the Convention.
1027. In determining whether Chinese activities at Mischief Reef are military in nature, the Tribunal
takes note of China’s repeated statements that its installations and island construction areintended to fulfil civilian purposes.1261 The Tribunal also takes note of the public statement ofChina’s President Xi Jinping that “[r]elevant construction activities that China are undertaking
in the island of South – Nansha Islands do not target or impact any country, and China does notintend to pursue militarization.”1262

1028. The Tribunal will not deem activities to be military in nature when China itself has consistently
resisted such classifications and affirmed the opposite at the highest level. Accordingly, theTribunal accepts China’s repeatedly affirmed position that civilian use comprises the primary (ifnot the only) motivation underlying the dramatic alterations on Mischief Reef. As civilian
activity, the Tribunal notes that China’s conduct falls outside the scope of Article 298(1)(b) andconcludes that it has jurisdiction to consider the Philippines’ Submission.
(b)

China’s Actions at Mischief Reef and the Philippines’ Sovereign Rights

1029. As a preliminary matter, and as noted previously in this Award (see paragraph 696 above), theTribunal is of the view that the Parties’ dispute in relation to the Philippines’ Submission No. 12
appears to stem from divergent understandings of their respective rights in the areas of theSouth China Sea within 200 nautical miles of the Philippines’ baselines that are encompassedby the ‘nine-dash line’, including Mischief Reef. Each Party, in other words, has conducted its
affairs from the premise that it, and not the other Party, has sovereign rights over Mischief Reef.
1030. However much these beliefs have been held in good faith, the Tribunal has found that Mischief
Reef is a low-tide elevation that falls within an area where only the Philippines possesses
possible entitlements to maritime zones under the Convention. Mischief Reef, therefore, canonly constitute part of the exclusive economic zone and continental shelf of the Philippines; itdoes not lie within any entitlement that could be generated by any feature claimed by China (oranother State).
i.

Acts in Relation to the Installations and the Construction of Islands at
Mischief Reef

1031. Having found that Mischief Reef lies within the exclusive economic zone and continental shelfof the Philippines, the Tribunal notes that the Convention is clear with respect to the law
governing artificial islands, installations, and structures.
1032. Article 56(1)(b) of the Convention provides that, within the exclusive economic zone, thecoastal State enjoys “jurisdiction as provided for in the relevant provisions of this Convention
with regard to: (i) the establishment and use of artificial islands, installations and structures.”1033. Article 60 then elaborates on this provision. Paragraphs (1) and (2) provide as follows:1.

In the exclusive economic zone, the coastal State shall have the exclusive right toconstruct and to authorize and regulate the construction, operation and use of:(a)artificial islands;

413

The South China Sea Arbitration
Award of 12 July 2016

2.

(b)

installations and structures for the purposes provided for in article 56 andother economic purposes;(c)installations and structures which may interfere with the exercise of the rightsof the coastal State in the zone.

The coastal State shall have exclusive jurisdiction over such artificial islands,
installations and structures, including jurisdiction with regard to customs, fiscal,
health, safety and immigration laws and regulations.

The remaining paragraphs of Article 60 address (a) the notice that must be given regarding theconstruction of artificial islands, installations, and structures; (b) the procedures with respect tosafety zones; and (c) the obligation to remove abandoned or disused installations and structures.
Article 60(8) also expressly provides that “[a]rtificial islands, installations and structures do notpossess the status of islands. They have no territorial sea of their own, and their presence does
not affect the delimitation of the territorial sea, the exclusive economic zone or the continental
shelf.”
1034. With respect to the continental shelf, Article 80 provides that “Article 60 applies mutatis
mutandis to artificial islands, installations and structures on the continental shelf.”
1035. These provisions speak for themselves. In combination, they endow the coastal State—which inthis case is necessarily the Philippines—with exclusive decision-making and regulatory powerover the construction and operation of artificial islands, and of installations and structures
covered by Article 60(1), on Mischief Reef.

Within its exclusive economic zone andcontinental shelf, only the Philippines, or another authorised State, may construct or operatesuch artificial islands, installations, or structures.
1036. The Tribunal considers that China’s initial structures on Mischief Reef from 1995 onwards
constituted installations or structures for the purposes of Article 60(1). The Tribunal takes
China at its word that the original purpose of the structures was to provide shelter for fishermen
and concludes that this is an economic purpose. The Tribunal also notes that the original
structures, which China declined to permit fishermen from the Philippines to use, also had thepotential to interfere with the exercise by the Philippines of its rights in the exclusive economiczone.

Accordingly, pursuant to Article 60 of the Convention, only the Philippines could

construct or authorise such structures.
1037. China’s activities at Mischief Reef have since evolved into the creation of an artificial island.
China has elevated what was originally a reef platform that submerged at high tide into an
island that is permanently exposed. Such an island is undoubtedly “artificial” for the purposesof Article 60. It is equally clear that China has proceeded without receiving, or even seeking,the permission of the Philippines. Indeed, China’s conduct has taken place in the face of the414

The South China Sea Arbitration
Award of 12 July 2016

Philippines’ protests. Article 60 is unequivocal in permitting only the coastal State to construct
or authorise such artificial islands.
1038. In light of these provisions of the Convention, the Tribunal considers China’s violation of its
obligations to be manifest.
ii.

Acts in Relation to Appropriation

1039. The Tribunal now turns to the Philippines’ Submission that China, through its occupation andconstruction activities, has unlawfully attempted to appropriate Mischief Reef.
1040. The Tribunal recalls, first, that Mischief Reef is incapable of appropriation. As the Tribunal has
already concluded at paragraphs 307 to 309 above, low-tide elevations “do not form part of theland territory of a State in the legal sense.” Rather, such features form part of the submerged
landmass of a State and, in the case of Mischief Reef, fall within the legal regime for thecontinental shelf. In consequence, low-tide elevations, as distinct from land territory, cannot beappropriated. As the Tribunal has now found, Mischief Reef is a low-tide elevation; it follows
from this that it is incapable of appropriation, by occupation or otherwise.
1041. As a low-tide elevation within the Philippines’ exclusive economic zone and continental shelf,
the legal relevance of Mischief Reef is that it lies within an area in which sovereign rights are
vested exclusively in the Philippines and where only the Philippines may construct or authorise
artificial islands. The Tribunal has already held in relation to the Philippines’ Submissions
No. 8 and 9 that China’s actions at Mischief Reef have unlawfully interfered with thePhilippines’ enjoyment of its sovereign rights.
1042. Having established that Mischief Reef is not capable of appropriation and addressed the effectof China’s actions on the Philippines’ sovereign rights, the Tribunal sees no need to address
Submission No. 12(c).
(c)

Conclusion

1043. Based on the considerations outlined above, the Tribunal finds that China has, through its
construction of installations and artificial islands at Mischief Reef without the authorisation of
the Philippines, breached Articles 60 and 80 of the Convention with respect to the Philippines’
sovereign rights in its exclusive economic zone and continental shelf. The Tribunal further
finds that, as a low-tide elevation, Mischief Reef is not capable of appropriation.

OPERATION OF LAW ENFORCEMENT VESSELS IN A DANGEROUS MANNER (SUBMISSION
NO. 13)
1.

Introduction

1044. In this Section, the Tribunal addresses the Parties’ dispute concerning China’s operation of its
law enforcement vessels near Scarborough Shoal. This dispute is reflected in the Philippines’
Submission No. 13, which requests a declaration that:(13)

China has breached its obligations under the Convention by operating its law
enforcement vessels in a dangerous manner causing serious risk of collision toPhilippine vessels navigating in the vicinity of Scarborough Shoal;

1045. In its Award on Jurisdiction, the Tribunal held that Submission No. 13 “reflects a disputeconcerning the operation of China’s law enforcement activities in the vicinity of ScarboroughShoal and the application of Articles 21, 24, and 94 of the Convention.”1263 The Tribunal foundthat the Submission did not concern “sovereignty or maritime delimitation.”1264 It determinedthat the dispute was not barred from its consideration by any requirement of Section 1 of Part
XV of the Convention. 1265

The Tribunal also concluded that Article 298(1)(b) of theConvention, which excludes certain disputes concerning “law enforcement activities” from theprocedures in Section 2, was inapplicable because that exception applies only in the context ofthe exclusive economic zone; the present dispute relates “principally to events that occurred in
the territorial sea” of Scarborough Shoal.1266 Finally the Tribunal considered its jurisdiction“not dependent on a prior determination of sovereignty over Scarborough Shoal.” 1267
Accordingly, the Tribunal found that it has jurisdiction to address the matters raised in
Submission No. 13.1268
2.

Factual Background1046. The facts underlying the present Submission concern interactions between Chinese law
enforcement vessels and Philippine coast guard and surveillance ships on 28 April 2012 and on
26 May 2012.

Near-Collision of Philippine Vessels BRP Pampanga and BRP Edsa II with
Chinese Vessel FLEC 310

1047. On 28 April 2012, BRP Pampanga, a Philippine Coast Guard ship conducting maritime patrol
and law enforcement activities in the vicinity of Scarborough Shoal, established contact withanother vessel, BRP Edsa II, in order to be relieved of its duties before returning to port. At
08:15 local time, the captain and commander of BRP Edsa II boarded the Pampanga for“briefing and turnover”.1269
1048. At 09:00, the Philippine vessels came in contact with FLEC 310, a vessel operated by China’s
Fisheries and Law Enforcement Command.1270 According to BRP Pampanga’s after operations
report, while the ship was stationary, FLEC 310 approached it “from port to almost dead ahead
at a distance of about 600 yards with speed of 20.3 knots.”1271
1049. Fifteen minutes later, at 09:15, FLEC 310 approached BRP Edsa II, 1272 passing from the“starboard quarter to the port side” of the ship at a distance of 200 yards and a speed of
20.6 knots.1273 BRP Pampanga’s after operations report describes the manoeuvre as creating
two-metre high waves in FLEC 310’s wake that “battered” two Philippine rubber boats, whichwere in the water at the time for the purpose of transferring personnel. 1274 At 09:25, BRP
Pampanga “turned over the area” to BRP Edsa II and began its voyage to Manila, where it
arrived that night.1275(b)Near-Collision of Philippine Vessel MCS 3008 with Several Chinese Vessels
upon Approach to Scarborough Shoal

1050. On 26 May 2012, MCS 3008, a Philippines Bureau of Fisheries and Aquatic Resources vessel,

Philippine Coast Guard.1276 At approximately 15:50 local time and having come within sevennautical miles of Scarborough Shoal, MCS 3008 was approached by CMS 71.1277
1051. According to the report of the Philippine Coast Guard officers aboard the MCS 3008, CMS 71“increased speed and at less than 100 yards” from the MCS 3008 and “attempted to cross thisunit’s port bow.”1278 MCS 3008 “responded by increasing speed to 20 knots and altering course
to the starboard” and then passing to the rear of the CMS 71 “in order to evade a possible
impact.”1279
1052. Once it “was able to evade the first dangerous maneuver of CMS 71,” MCS 3008 reported, “thesame vessel immediately swinged to its starboard and again attempted to cross [the] starboard
bow of [MCS 3008].”1280 In response, and “in order to avoid a possible collision ensued by thissecond intentional act of CMS 71,” MCS 3008 “immediately maneuvered hard port” and“passed through the rear of [CMS 71].”1281
1053. After steering clear of the “deliberate maneuvers of CMS 71,” MCS 3008 reported that it wasapproached by another Chinese vessel, FLEC 303, which “steered towards our position and . . .
aimed to cross [MCS 3008]’s starboard bow.” 1282 MCS 3008 “instantly . . . reacted byincreasing speed to 22 knots and swerving towards the rear of FLEC 303” in order to avoid acollision.1283
1054. Following these incidents, MCS 3008 continued toward BRP Corregidor. During this time,MCS 3008 was pursued by three Chinese vessels: FLEC 303, CMS 71, and CMS 84 (a third
Chinese vessel, also belonging to CMS).1284 All three Chinese vessels pursued MCS 3008 until
the latter approached BRP Corregidor. While MCS 3008 was alongside BRP Corregidor,
CMS 84 “passed through starboardside of our position at a distance of less than 100 yards.” 1285
According to MCS 3008, CMS 84 “eventually stopped and positioned on the port quarter at a

distance of approx. 500 yards from our position.”1286 At the same time, a fourth Chinese vessel,
FLEC 301, “was stationed at the port beam with a distance of about one thousand (1,000)
yards.”1287
1055. After checking the tidal level, MCS 3008 proceeded towards the entrance to the lagoon of
Scarborough Shoal.1288 As MCS 3008 pulled away from BRP Corregidor, CMS 84 again began
to chase. According to the officers of MCS 3008, “sensing that CMS 84 was aiming to crossthrough the bow of this vessel, this unit increased speed which eventually caused the Chinese
vessel to be left behind by a few yards.”1289
1056. As MCS 3008 continued toward the lagoon entrance, three Chinese vessels, FLEC 303,
CMS 71, and FLEC 306 approached it. As reported by MCS 3008,
when FLEC 303 was already about 50 yards from this vessel, said Chinese vessel
immediately altered course as if crossing to our starboard bow. However, when FLEC 303
was already dead ahead of this unit, the Chinese vessel decreased speed and established ablocking position. [MCS 3008] right away swerved towards the rear of the Chinese vesselto evade a possible impact.1290

1057. Thereafter, MCS 3008 “sighted CMS 71 moving fast towards our position. Again, because of
our speed, CMS 71 was only able to get near our position from a distance of approximately
70 yards on our portside.”1291
1058. At the entrance to the lagoon, MCS 3008 encountered FLEC 306, along with three Chinese
fishing vessels. MCS 3008 described this incident as follows:
On our route towards the basin, this vessel sighted three (3) Chinese fishing vessels and
FLEC 306 on a blocking position near the lone entrance inside the shoal. Furthermore,
three (3) Chinese service ships were now chasing this unit with CMS 71 joining CMS 84
and FLEC 303.
After being able to position [a] few yards from the entrance of the shoal and reviewing our
prepared safe way points, this unit decided to enter the shoal’s basin by passing in between
the three (3) Chinese fishing vessels (CFV’s) and FLEC 306 which was fast moving
towards our location. This unit considered such path as the only possible way towards thebasin because of our safe distance from the CFV’s and FLEC 306 in which, all the while
seemed to have given way for the entry of this vessel inside. However, as this unit was on
its way towards the basin, ships personnel sighted two (2) mooring lines which was plantedby CFV’s obviously intended to impede our movement towards the shoal’s basin. While
this unit stopped engines and then maneuvered backwards to avoid the lines, crew of the
CFV’s from which the line came from and FLEC 306 suddenly echoed cheers and clapped

hands. At this point, FLEC 306 was already on a blocking position [a] few yards deadahead of this unit.
With the lines planted by the CFV’s, FLEC 306 posing a blockade and three (3) Chinese
service ships positioned at the rear, it was evident that all efforts by the Chinese vessels
were already employed in order to obstruct our entry to the shoal’s basin. Nevertheless,with the sheer determination to comply with the directive from higher-ups for this vessel to
go inside the shoal’s basin coupled with the courage that the officers and crew exuded onsuch situation, this unit sped up, maneuvered hard to the starboard and swerved toward theastern of FLEC 306.
The scenario went worse this time with FLEC 306 going all engines back and determined
to ram our vessel. Nevertheless, this unit continued to employ speed and immediately
maneuver[ed] hard left which was just enough to dodge from the deliberate intention ofsaid FLEC which was just about 10 meters away on our portside and at the same time, tokeep this vessel safe from a shallow area approximately 25 yards away on the
starboardside. . . .
After avoiding the chase, harassment and intended sabotage, finally, this unit was able toenter the shoal basin safely and anchored . . . .1292

The Philippines’ Position

1059. The Philippines alleges that China has operated its law enforcement vessels in a dangerous
manner, causing “serious risk[] of collision” to Philippine vessels navigating in the vicinity of
Scarborough Shoal.1293 In consequence, the Philippines submits that China has breached its
obligations relating to safe navigation under Articles 94 and 21 of the Convention and related
provisions in the Convention on the International Regulations for Preventing of Collisions at
Sea, 19721294 (the “COLREGS”).1295(a)

The Applicability of the COLREGS to China

1060. The Philippines submits, first, that China’s conduct in the territorial sea of Scarborough Shoal isgoverned and constrained by the general requirements of flag States under the Convention. In
this regard, it recalls the Fisheries Advisory Opinion, in which the International Tribunal for the
Law of the Sea held that the Convention “contains provisions concerning general obligations”
which must be met by flag States “in all marine areas regulated by the Convention,” including
those regulated by Articles 91, 92, and 94 of the Convention.1296 It follows, in the Philippines’

view, that China has obligations under the Convention whenever its vessels, “including those
operated by CMS and FLEC . . . are operated in the territorial sea of Scarborough Shoal or
anywhere else.”1297 In other words, the obligations of a flag State apply “regardless of where
the ships were located” at any particular point in time.1298
1061. The Philippines recalls that Article 94(3) of the Convention requires flag States to “take suchmeasures . . . as are necessary to ensure safety at sea,” including measures concerning “the useof signals, the maintenance of communications and the prevention of collisions.” 1299 The
Philippines also refers to Article 94(5), which clarifies the scope of the flag State’s duties in thefollowing terms:
In taking the measures called for in paragraphs 3 and 4 each State is required to conform togenerally accepted international regulations, procedures and practices and to take any steps
which may be necessary to secure their observance.1300

1062. Finally, the Philippines notes that Article 21(4) of the Convention also refers to “international
regulations relating to the prevention of collisions at sea.” 1301
1063. The correct interpretation of the aforementioned provisions, in the Philippines’ view, includes
the COLREGS as one of the “generally accepted international regulations” to which flag States
are required to conform.1302 The International Maritime Organisation, for example, recognises
the COLREGS as one of its conventions that “may, on account of their world-wide acceptance,
be deemed to fulfil the requirement of general acceptance” for the purposes of Article 94(3).1303
1064. The Philippines submits that while Article 21(4) technically applies only to foreign ships ininnocent passage, if the coastal State fails to ensure its vessels respect COLREGS in the
territorial sea and subsequently endangers the navigation of foreign ships in the territorial sea,
this would constitute a violation of its duties under Article 24 to refrain from hampering
innocent passage and to publicise dangers to navigation.1304

1065. According to the Philippines, the COLREGS are legally binding rules.1305 By their terms, theyextend to “all vessels upon the high seas and in all waters connected therewith navigable byseagoing vessels” 1306 and apply to “the high seas, the EEZ, the territorial sea, archipelagic
waters, [and] straits used for international navigation and archipelagic sea lanes.” 1307 They
therefore bind China with respect to its vessels operating in the vicinity of Scarborough Shoal.
1066. While the Philippines acknowledges that Rule 2(b) of the COLREGS recognises “special
circumstances” in which a departure from the rules may be “necessary to avoid immediate
danger,” it maintains that the exception “does not undermine the otherwise mandatory nature of
the regulations.”1308 It notes the practice of national courts in limiting that exception only tocircumstances raising “immediate” danger, rather than “generic special circumstances”.1309 In
any event, the Philippines considers the exception in Rule 2(b) to be inapplicable in the present
case.1310(c)

Application of the COLREGS to Chinese Vessels at Scarborough Shoal

1067. The Philippines submits that China has violated Rules 2, 6, 7, 8, 15, and 16 of the
COLREGS.1311 In so doing, the Philippines relies on the expert report of Professor Craig H.
Allen (the “Allen Report”).1312 Professor Allen is a Professor of Law and Adjunct Professor of
Marine Affairs at the University of Washington in Seattle, and served for 21 years with theUnited States Coast Guard. Professor Allen produced his expert report pro bono.1313 Relying
on the contemporaneous reports and dispatches provided to him by the Philippines, Professor
Allen considers China to have violated Rules 2, 6, 8, and 16 of the COLREGS on bothoccasions comprising the basis for Submission No. 13.

1068. The Philippines argues first that China is in breach of the general principle of responsibility forthe prevention of collisions provided in Rule 2. That provision states:
Rule 2. RESPONSIBILITY(a) Nothing in these Rules shall exonerate any vessel, or the owner, master or crew thereof,
from the consequences of any neglect to comply with these Rules or of the neglect of any
precaution which may be required by the ordinary practice of seamen, or by the special
circumstances of the case.
(b) In construing and complying with these Rules due regard shall be had to all dangers ofnavigation and collision and to any special circumstances, including the limitations of thevessels involved, which may make a departure from these Rules necessary to avoid
immediate danger.1314

1069. The Philippines argues that the conduct of Chinese vessels in both the 28 April and
26 May 2012 incidents place China in breach of Rule 2. Relying on the Allen Report, thePhilippines describes the conduct of FLEC 310 (on 28 April 2012) and of CMS 71, FLEC 303,and FLEC 306 (on 26 May 2012) as having “intentionally endanger[ed] another vessel throughhigh speed ‘blocking’ or harassment maneuvers.”1315 With regard to Rule 2, Professor Allenstates that Chinese vessels “demonstrated serious and apparently intentional breaches” of therequirement that ships take “precautions as are required by the ordinary practice of seamen.” 1316
Based on an analysis of the vessels’ conduct, the Allen Report concludes that the Chinese
vessels showed “a flagrant disregard of the tenets of good seamanship”1317 on both occasions.
1070. Second, the Philippines maintains that the Chinese vessels breached Rule 6 of the COLREGS,
requiring vessels to “proceed at a safe speed so that [they] can take proper and effective action
to avoid collision.” 1318 Professor Allen considers Rule 6 to have been violated when Chinese
vessels passed BRP Pampanga and BRP Edsa II at distances of 600 and 200 yards and speeds ofover 20 knots.1319 The Philippines notes that the interpretation of the term “safe speed” is not
specified and is thus contingent on the particular facts of each case, but maintains that thecircumstances of the two incidents leave little doubt that China failed to ensure that its vessels“proceed[ed] at a safe speed” in accordance with the regulation. 1320 The failure, in the1314

Philippines’ view, was further aggravated by the size of the Chinese vessels and the wakecreated by the manoeuvres, heightening the threat to the Philippine ships and their crews.1321
1071. Third, the Philippines argues that the Chinese vessels breached Rules 7 and 8 of the COLREGS,
which set out the principles governing the risk of collision and avoidance of collision,respectively.1322
1072. In the Philippines’ view, the Chinese vessels failed to take the necessary steps in accordancewith Rule 8, which requires evasive action to have “due regard to the observance of goodseamanship” and achieve passing at a “safe distance.” 1323 Although the COLREGS do not
define what constitutes a “safe distance” and the Philippines recognises the determination iscontext-specific, it submits that the term implies that “the passing distance must be large enoughto leave a margin for error and allow for the unexpected,” such as to provide for a “margin forhuman error or mechanical malfunction.”1324 The Philippines submits, supported by the Allen
Report, that the Chinese vessels “not only fail[ed] to take actions to avoid collision but [took]
actions that made collision substantially more likely.”1325 That no collision actually occurred
during the incidents in question does nothing to diminish China’s culpability, in the Philippines’
view, since it considers both rules to impose an obligation of conduct, rather than result.1326
1073. Finally, the Philippines, supported by the Allen Report, alleges breach of Rules 15 and 16 of the
COLREGS, both of which it considers to have been violated. Rule 15 states:
When two power-driven vessels are crossing so as to involve risk of collision, the vessel
which has the other on her own starboard side shall keep out of the way and shall, if thecircumstances of the case admit, avoid crossing ahead of the other vessel. 1327

The Philippines’ notes that Rule 15 requires that “the vessel on the left . . . turn away”1328 andsubmits that, when CMS 71 approached MCS 3008 at speed from the left (i.e., with MCS on the
starboardside of CMS 71) on 26 May 2012 “it was the ‘give-way vessel’ according toRule 15.”1329 Nevertheless, CMS 71 attempted to cross ahead of the Philippine vessel, rather
than avoiding such a manoeuvre as called for by Rule 15. In the context of Rule 15, Professor

Allen principally notes the failure of CMS 71 to give MSC 3008 right of way by attempting to
cut across the latter’s bow on 26 May 2012.1330
1074. Additionally, as the “give-way vessel”, the Philippines submits that CMS violated Rule 16,
regarding the obligations of the give-way vessel, insofar as “CMS 71 was . . . under the
obligation to ‘keep out of the way’ of the MCS 3008, which she did not do.”1331 Professor Allen
notes that, by “intentionally closing [in] on [the Philippine] vessels” in an attempt to block theirprogress toward Scarborough Shoal, the Chinese vessels—FLEC 310 in particular—“violated
Rule 16’s requirement to ‘so far as possible, take early and substantial action to keep wellclear’.” 1332 The Philippines likewise argues that “during the incident of 28 April 2012, theFLEC 310’s approach toward Philippine vessels made it the ‘give-way vessel’, requiring that it‘so far as possible, take early and substantial action to keep well clear’.”1333
1075. Professor Allen recognises that the operational requirements of law enforcement ships (such as
intercepting a vessel) may stand in “occasional tension” with the COLREGS. He cautions,however, that Rule 2(b) permits only limited exception from Rule 16, to “avoid immediate
danger”.1334 Professor Allen finds no such danger justifying a departure from the regulations.
He concludes that the incidents alleged by the Philippines “apparently involved intentional
violations of the most basic rules for preventing collisions at sea” and would be “condemned by
all professional mariners.”1335

China’s Position

1076. China has made no statements as to the specific matters raised in the Philippines’ Submission
No. 13, concerning the incidents in the vicinity of Scarborough Shoal on 28 April and
26 May 2012. It has, however, made statements concerning the presence of Chinese vessels at
Scarborough Shoal, both generally and in response to Philippine diplomatic notes concerning
the incidents.
1077. On 30 April 2012, the Department of Foreign Affairs of the Philippines submitted a Note
Verbale to the Embassy of the People’s Republic of China in Manila expressing the Philippines’

“grave concern over the provocative and extremely dangerous maneuvers” committed by
Chinese vessels at Scarborough Shoal.1336 The Philippines referred to the incident on 28 April
2012 and requested China “to instruct its ships to observe the [COLREGS].”1337
1078. In response to this and several other Philippine diplomatic notes expressing “grave concern”
over the conduct of Chinese vessels in the area,1338 on 25 May 2012, China replied that it “doesnot accept the contents” of the Philippines’ notes and asserted that the conduct of its vessels wasjustified. China stated:
The various jurisdiction measures adopted by the Chinese government over Huangyan
Island [Scarborough Shoal] and its waters, and activities by Chinese ships, including
government public service ships and fishing boats, in Huangyan Island and its waters arecompletely within China’s sovereignty.
...
The Chinese side once again urges the Philippine side to concretely respect China’s
territorial sovereignty over Huangyan Island, immediately pull out all Philippine ships fromthe Huangyan Island waters and desist from disturbing the operation of Chinese fishingboats and law enforcement activities by China’s public service ships. 1339

1079. While China has responded to specific Philippine allegations relating to the conduct of Chinese
vessels at Scarborough Shoal, it has specifically addressed only an encounter that occurred on
10 April 2012.1340 For example, in its Position Paper, China maintained that the presence ofPhilippine naval vessels at Scarborough Shoal on 10 April 2012 constituted “provocations” that“forced [China] to take response measures to safeguard its sovereignty.” 1341 More generally,
China has stated that “the legality of China’s actions in the waters of the Nansha Islands and

Huangyan Dao rests on both its sovereignty over relevant maritime features and the maritime
rights derived therefrom.”1342
1080. As far as the Tribunal is aware, China has not made specific statements with respect to theincidents of 28 April and 26 May 2012. Accordingly, the Tribunal does not have explicit
Chinese statements concerning the incidents alleged by the Philippines in its Submission
No. 13. However, the Tribunal considers China’s statements described above as indicating thatit considers its actions at Scarborough Shoal to have been generally lawful.
5.

The Tribunal’s Considerations(a)

Background on the COLREGS

1081. The COLREGS, entered into force on 15 July 1977. With 156 contracting parties representing
more than 98 percent of world tonnage, the COLREGS comprise one of the most widely adopted
multilateral conventions in force.

Both China and the Philippines are parties to the

COLREGS.1343
1082. Although the Philippines did not become a party to the COLREGS until 2013, in assessing thePhilippines’ Submission No. 13 the Tribunal considers the COLREGS to bind both Parties
relating to the conduct of their respective vessels by virtue of Article 94 of the Convention.
Article 94(1) of the Convention requires flag States to effectively exercise their “jurisdiction
and control” in administrative, technical, and social matters over ships flying their flag. 1344
Subsection 3 of that article clarifies the scope of flag States’ duties, requiring them to “take suchmeasures . . . as are necessary to ensure safety at sea,” including measures concerning, interalia, “the use of signals, the maintenance of communications and the prevention ofcollisions.”1345 The precise scope of those obligations is clarified in Article 94(5):In taking the measures called for in paragraph[] 3 . . . each State is required to conform togenerally accepted international regulations, procedures and practices and to take any steps
which may be necessary to secure their observance.1346

1083. In the Tribunal’s view, Article 94 incorporates the COLREGS into the Convention, and they areconsequently binding on China. It follows that a violation of the COLREGS, as “generally
accepted international regulations” concerning measures necessary to ensure maritime safety,
constitutes a violation of the Convention itself. With this in mind, the Tribunal turns to the
independent expert opinion and factual record regarding the two incidents and to an evaluationof China’s conduct in light of the applicable regulations.
(b)

Report of Tribunal-Appointed Independent Expert

1084. In assessing the present Submission, the Tribunal takes into account the Allen Report, submitted
by the Philippines, as well as the report of 15 April 2016 by Captain Gurpreet S. Singhota, 1347
who was appointed by the Tribunal in accordance with Article 24 of the Rules of Procedure inorder to obtain an independent expert assessment of the Philippines claims. Captain Singhota’s
experience includes 26 years of service with the International Maritime Organization’s
Maritime Safety Division, Sub-committee on Safety of Navigation, and other departments, aswell as 14 years of seagoing experience. Captain Singhota certified that he “is, and shallremain, impartial and independent with respect of each of the Parties.”1348
1085. After a review of the factual record, Captain Singhota concludes that China has breached its
obligations under Rules 2, 6, 8, 15, and 16 of the COLREGS.
1086. With respect to the alleged incidents of 28 April 2012, Captain Singhota finds that high-speed
manoeuvring by FLEC 310 in the vicinity of BRP Pampanga, veering away a distance ofapproximately 0.32 nautical miles from the Philippine vessel, exemplifies “unprofessional shiphandling . . . totally inconsistent with the practice of good seamanship.” 1349

In suchcircumstances, a “momentary decision-making lapse,” Captain Singhota suggests, could haveresulted in a “catastrophic collision”.1350 He therefore considers FLEC 310’s conduct to haveviolated Rule 2(a) of the COLREGS.

Noting FLEC 310’s high speed at the time of its

encounters with BRP Pampanga and Edsa II (20.3 and 20.6 knots, respectively), the report also
identifies a breach of Rule 6 relating to safe speed in the prevailing situations.1351

Award of 12 July 2016

1087. Captain Singhota attributes two additional breaches to FLEC 310’s conduct under Rules 8 and
16 of the COLREGS.

He explains that where risk of collision exists, Rule 8 imposes

obligations on give-way vessels to “take timely action to keep clear” and to maintain a safe
distance from the other ship. Observing that thresholds for “safe” distances vary and arecontext-specific, the report concludes that FLEC 310’s closing in, within 600 yards(0.296 nautical miles) and 200 yards (0.098 nautical miles), respectively, of the Philippine
vessels “certainly” fell short of the requirement of passing at a safe distance. 1352 Because
Rule 16 requires give-way vessels to take “early and substantial” action to maintain a safe
distance, the report also considers that provision to have been violated over the course of theencounter.1353
1088. With respect to the alleged incidents of 26 May 2012, Captain Singhota considers the“high-speed blocking” manoeuvres of FLEC and CMS vessels vis-à-vis MCS 3008 to constitutea “total disregard of good seamanship and neglect of any precaution, which may be required by
the ordinary practice of seamen.”1354 In particular, the report deems the conduct of CMS 71,
FLEC 303, and FLEC 306, and especially CMS 71’s attempt to cut across the bow of MCS
3008 at a distance of fewer than 100 yards (0.049 nautical miles), to have breached Rules 2, 6,
and 8 of the COLREGS.1355 The report considers CMS 71 “unnecessarily” attempting to cut
across the bow of MCS 3008 also to violate Rule 15:
To cross another vessel’s bow unnecessarily, where collision is probable, or even only
possible, is an unseamanlike manoeuvre, and apart from the regulations would be held to be
negligent in fact and in law.1356

Finally, Captain Singhota considers that the actions of the Chinese vessels “created situations
that required them to assume the role of the give-way vessel.”1357 As such, Rule 16 required
them to “so far as possible, take early and substantial action to keep well clear.”1358
1089. Captain Singhota concludes that the Chinese manoeuvres on 26 April and 28 May 2012
“demonstratedacomplete

Application of Article 94 of the Convention and the COLREGS

1090. Having determined that Article 94 of the Convention incorporates the COLREGS into the duties
of flag States by reference, the Tribunal must interpret and apply the COLREGS in order tomake decisions as to the Philippines’ Submission No. 13.
1091. As a preliminary matter, the Tribunal observes that the conduct of each of the Chinese vessels inquestion—CMS 71, CMS 84, FLEC 303, FLEC 306, and FLEC 310—is attributable to China.
All Chinese-flagged vessels involved in the incidents alleged by the Philippines on 28 April and
26 May 2012 belonged to one of two agencies: CMS or the FLEC. Accordingly, because theconduct complained of was committed by vessels falling directly under the command andcontrol of the Chinese Government, the Tribunal considers the vessels’ behaviour to constituteofficial acts of China. Their conduct is automatically attributable to China as such.
1092. Having regard to the entirety of the record before it, the Tribunal determines that the activities
of Chinese vessels implicated in Submission No. 13 constituted violations of the COLREGS.
1093. The Tribunal notes that the evidence demonstrates that FLEC 310 passed within 200 yards of
BRP Edsa II and within 600 yards of BRP Pampanga, in both cases at a speed of more than
20 knots. Similar conduct occurred on 26 May 2012, during which CMS 71 and FLEC 303
attempted to cut across the bow of MCS 3008 on three occasions, once at a distance of less than
100 yards.1360
1094. Such conduct is irreconcilable with an obligation of responsible navigation. In this regard, theTribunal accepts Captain Singhota’s characterisation of the Chinese vessels’ conduct as having
been in “total disregard of good seamanship and neglect of any precaution.”1361 It follows that
Rule 2(a) was breached by each of the aforementioned incidents.
1095. In this connection, moreover, the Tribunal considers the exception posed by Rule 2(b),permitting departure from the COLREGS where “necessary to avoid immediate danger,”
inapposite to the case at hand. Quite apart from the Philippines’ argument that national courts,

Award of 12 July 2016

such as those in the United States, 1362 construe the exception narrowly, the high thresholdestablished by the exception cannot apply to the facts as presented. If anything, the recordsuggests that the Chinese manoeuvres themselves created an immediate danger, rather thanhaving been undertaken in response to a pre-existing threat.1363 Additionally, while the Tribunal
is aware that China’s statements suggest that its actions were justified as part of general law
enforcement activities in the vicinity of a feature which China considers to comprise part of its
sovereign territory, the Tribunal also recognises that, where the operational requirements of law
enforcement ships stand in tension with the COLREGS, the latter must prevail. 1364
Accordingly, the Tribunal can find no danger justifying a departure from the regulations under
Rule 2(b).
1096. The Tribunal turns next to Rule 6 of the COLREGS, which requires ships to preserve the means
to avoid collision when circumstances so require. It provides, in relevant part, that:
Every vessel shall at all times proceed at a safe speed so that she can take proper andeffective action to avoid collision and be stopped within a distance appropriate to theprevailing circumstances and conditions. 1365

1097. On 28 April 2012, FLEC 310 passed by BRP Pampanga at 20.3 knots and Edsa II at 20.6 knots(see paragraphs 1048 to 1049 above). The COLREGS do not define what constitutes a “safespeed”, and the meaning and application of the phrase remains dependent on the particular factsof each case, including factors such as the vessels’ size and probability of harm. In thisinstance, however, both Professor Allen and Captain Singhota 1366 consider the incidents
described above to have occurred at unsafe speeds. The Tribunal concurs with that view anddetermines that the Chinese vessels’ actions breached Rule 6.
1098. Next, the Tribunal turns to Rules 7 and 8 of the COLREGS. Rule 7(a) provides: “Every vessel
shall use all available means appropriate to the prevailing circumstances and conditions todetermine if risk of collision exists. If there is any doubt such risk shall be deemed to exist.”1367
Both experts conclude that such a risk existed on 28 April and 26 May 2012. The Allen Reportconcludes a breach of Rule 7 occurred in each of three instances: (a) FLEC 303 closing at highspeed within 600 yards of BRP Pampanga and passing BRP Edsa II within 200 yards;

The Singhota Report reaches a similar conclusion, although its analysis

primarily evaluates the incidents under the framework of Rule 8 (which presumes that a risk ofcollision exists). 1369 Under these circumstances, the Tribunal considers the “risk” identified
under Rule 7 to have been clearly established.
1099. Having established that a “risk of collision” existed, the Tribunal turns to Rule 8, which governs
the means by which vessels may act to avoid such risks, as follows:
Any action taken to avoid collision shall be taken in accordance with the Rules of this Partand shall, if the circumstances of the case admit, be positive, made in ample time and with
due regard to the observance of good seamanship.
...
Action taken to avoid collision with another vessel shall be such as to result in passing at asafe distance. The effectiveness of the action shall be carefully checked until the othervessel is finally past and clear.1370

1100. Rule 8 of the COLREGS does not define what constitutes a “safe distance”. Professor Allensuggests that the term be read to imply that “the passing distance . . . be large enough to leave amargin for error and allow for the unexpected.” 1371 Captain Singhota proposes that a “safedistance” must allow for “human error on the bridge and engine or [for] steering gear failure at a
critical phase of the maneuver,” as well as for any incidental effects of the “interaction” between
passing vessels.1372 In any event, the Tribunal considers the conduct of FLEC 303, FLEC 306
FLEC 310, and CMS 71 all to fall short of any reasonable definition of a safe distance.
1101. Indeed, far from avoiding a collision, the actions of the Chinese ships made the possibility of acollision substantially more likely. 1373 That fact alone—independent of any question as towhether a collision, whether through the crew’s effort or by good fortune, was ultimately
averted—suffices to demonstrate a violation of the COLREGS. For the same reasons as thoseunderlying its conclusion with respect to Rule 2(a), the Tribunal considers the other requirement

imposed by Rule 8, namely “due regard to the observance of good seamanship,” also to havebeen violated.
1102. Finally, the Tribunal considers Rules 15 and 16, relating to right-of-way. Rule 15 states thatwhen two power-driven vessels are crossing so as to involve a risk of collision, the vessel“which has the other on her own starboard side shall keep out of the way and shall, if thecircumstances of the case admit, avoid crossing ahead of the other vessel.”1374
1103. Rule 16, in turn, requires that “[e]very vessel which is directed . . . to keep out of the way of
another vessel shall, so far as possible, take early and substantial action to keep well clear.”1375
1104. On 28 April 2012, FLEC 310 approached BRP Pampanga to within 600 yards; fifteen minutes
later, it passed BRP Edsa II from the starboard quarter to the port side at a distance of “barely
200 yards”.1376 In other words, rather than abiding by the applicable regulations by “keep[ing]out of the way” and avoiding the other ship, FLEC 310 did the opposite. The attempt by
CMS 71, on 26 May 2012, to cut across the bow of MCS 3008 from the port (left) side at a
distance of merely 100 yards admits of the same error. Accordingly, both incidents constituteda breach of the Rules of the COLREGS in this respect.
1105. In light of the foregoing analysis, the Tribunal considers China to have repeatedly violated theRules of the COLREGS over the course of the interactions described by the crew of thePhilippine vessels and as credibly assessed in the two expert reports. Where Chinese vessels
were under an obligation to yield, they persisted; where the regulations called for a safe
distance, they infringed it. The actions are not suggestive of occasional negligence in failing toadhere to the COLREGS, but rather point to a conscious disregard of what the regulations
require. The various violations are underscored by factors such as the large disparity in size of
the Chinese and Philippine vessels, the shallow waters in which the incidents took place, and thecreation of a two metre-high wake causing additional risk to the Philippines’ crews.1377
1106. The Tribunal notes that, in addition to the COLREGS themselves, the Singhota Report identifies

Committee Resolution on 17 May 2010, entitled “Assuring safety during demonstrations,protests or confrontations on the high seas.”1378 The resolution calls upon governments to urge:(1)

persons and entities under their jurisdiction to refrain from actions that intentionallyimperil human life, the marine environment, or property during demonstrations,protests or confrontations on the high seas; [and]

...
(3)

all vessels, during demonstrations, protests or confrontations on the high seas, tocomply with COLREG and SOLAS by taking all steps to avoid collisions andsafeguard navigation, security and safety of life at sea.1379

While this resolution operates in the context of the high seas, the text is of interest insofar as it
confirms the priority of maritime safety even in situations of confrontation.
1107. As the Allen Report makes clear, “operational requirements” of law enforcement vessels such as
those of CMS and FLEC occasionally stand in tension with the obligations imposed by the
COLREGS, without diminishing the nature or binding force of their provisions. 1380 In thisregard, the Tribunal having reviewed the record relevant to Submission No. 13 and having
considered possible circumstances precluding wrongfulness has found no convincing evidence
that the aforementioned violations are excusable by any mitigating circumstances.
1108. The Tribunal emphasises again that its determinations in Submission No. 13 do not depend
upon, and do not involve any finding of sovereignty over Scarborough Shoal and its waters.
The same conclusions about violations of the navigational safety provisions of the Convention
would be reached irrespective of which State has sovereignty over Scarborough Shoal. The
Tribunal does not purport to make a finding on that question.
(d)Conclusion

1109. Based on the considerations outlined above, the Tribunal finds that China has, by virtue of the
conduct of Chinese law enforcement vessels in the vicinity of Scarborough Shoal, createdserious risk of collision and danger to Philippine vessels and personnel. The Tribunal finds
China to have violated Rules 2, 6, 7, 8, 15, and 16 of the COLREGS and, as a consequence, tobe in breach of Article 94 of the Convention.

VIII. AGGRAVATION OR EXTENSION OF THE DISPUTE BETWEEN THE PARTIES(SUBMISSION NO. 14)
A.

INTRODUCTION

1110. In this Chapter, the Tribunal addresses the Parties’ dispute concerning China’s actions since thecommencement of this arbitration in January 2013, which the Philippines argues have“aggravated and extended the dispute.” This dispute is reflected in the Philippines’ Submission
No. 14, which provides as follows (as amended):(14)

Since the commencement of this arbitration in January 2013, China has unlawfully
aggravated and extended the dispute by, among other things:(a)interfering with the Philippines’ rights of navigation in the waters at, andadjacent to, Second Thomas Shoal;(b)

preventing the rotation and resupply of Philippine personnel stationed atSecond Thomas Shoal;(c)endangering the health and well-being of Philippine personnel stationed atSecond Thomas Shoal; and(d)conducting dredging, artificial island-building and construction activities at
Mischief Reef, Cuarteron Reef, Fiery Cross Reef, Gaven Reef, Johnson Reef,
Hughes Reef and Subi Reef; and1111. Paragraphs (a) to (c) of Submission No. 14 comprised the initial formulation of this Submission,and concern China’s interactions with the Armed Forces of the Philippines at Second Thomas
Shoal.1381 In light of the “extensive land reclamation activities” undertaken by China at many ofthe disputed features since the commencement of this dispute, 1382 the Philippines sought toamend Submission No. 14 to include paragraph (d), concerning China’s dredging, artificial
island-building, and construction activities at Mischief Reef, Cuarteron Reef, Fiery Cross Reef,
Gaven Reef, Johnson Reef, Hughes Reef, and Subi Reef, when presenting its final Submissions
at the end of the Hearing on the Merits.1383 On 16 December 2015, after having invited China’scomments on the requested amendments, the Tribunal gave the Philippines leave to amend its
Submissions, noting in this respect that “the requested amendments are related to or incidental
to the Submissions originally made by the Philippines and do not involve the introduction of a
new dispute between the Parties.”1384

FACTUAL BACKGROUND

1112. Reflecting the different factual matters alleged by the Philippines to have aggravated andextended the Parties’ dispute, the Tribunal will separately address (a) the events that occurred inand around Second Thomas Shoal, and (b) China’s various construction activities at Mischief
Reef, Cuarteron Reef, Fiery Cross Reef, Gaven Reef (North), Johnson Reef, Hughes Reef, andSubi Reef.
1.

Chinese Actions in and around Second Thomas Shoal

1113. On 7 May 1999, the Philippine Navy grounded BRP Sierra Madre on Second Thomas Shoal,
where it has remained to the present day.1385 BRP Sierra Madre is a tank landing ship designed
for offloading tanks and other heavy equipment onto an unimproved beach. She was built by
the United States in 1944 and transferred to the Philippines in 1976. Since May 1999, thePhilippines has maintained a detachment of approximately seven marines on board BRP Sierra
Madre.1386 This detachment is resupplied at regular intervals and the personnel rotated.1387
1114. On 22 January 2013, the Philippines commenced this arbitration by way of a Notification andStatement of Claim served on China. On 19 February 2013, China rejected and returned thePhilippines’ Notification and Statement of Claim.1388(a)China’s Objections to the Presence of BRP Sierra Madre at Second Thomas

1116. In April 2013, China objected to the continued presence of BRP Sierra Madre on at least threeoccasions. As recorded by the Philippines, these objections were made on 11 April 2013, when
the Philippine Ambassador to China met with the Special Representative of the Department ofBoundary and Ocean Affairs of the Chinese Ministry of Foreign Affairs, on 16 April 2013 when
the Chinese Ambassador to the Philippines met with an Undersecretary of the Philippine
Ministry of Foreign Affairs, and on 17 April 2013, when the Philippine Ambassador to China
met with the Chinese Vice Foreign Minister.1390 As recorded by the Philippines, China objectedthat “the Philippine Navy vessel BRP Sierra Madre (LST 57), on the pretext of being stranded,was ‘illegally grounded’ on Second Thomas Shoal” and that “Philippine authorities promised
China that they would immediately remove the stranded vessel but they have not done so up to
this day.”1391 At the first of these meetings, the Chinese representative was also recorded assaying that China “would not allow the continuous stranding of the vessel.”1392
1117. Beginning on 3 May 2013, the Armed Forces of the Philippines reported a significant increasein the presence of Chinese Government vessels at Second Thomas Shoal, including two Chinese
Navy frigates and five Civilian Maritime Law Enforcement Agency vessels on a rotationbasis.1393
1118. On 9 May 2013, the Philippines delivered a Note Verbale to China, objecting to the presence ofChinese vessels in the area of Second Thomas Shoal. After asserting that Second Thomas Shoal
forms part of the continental shelf of the Philippines, the Note Verbale went on to state as
follows:
The Philippines notes that under UNCLOS, State Parties are obliged to “refrain from any
threat or use of force against the territorial integrity or political independence of any State,”or conduct any activities that are in “any manner inconsistent with the principles ofinternational law embodied in the UN Charter.” In this context, the Philippines protests the
provocative and illegal presence of the following Chinese vessels in the vicinity of Ayungin[Second Thomas] Shoal:•

Two (2) China Marine Surveillance (CMS) ships located at 0720H 04 May 2013 at
vicinity three nautical miles East of Ayungin Shoal in the West Philippine Sea; and•One (1) Chinese warship believed to be a Type 053H1G (Jianghu-V Class) Missile
Frigate with bow number 563 between Ayungin Shoal and Rajah Solaiman Reef

Award of 12 July 2016...
The Philippines notes that it has filed a third-party adjudication under Annex VII of
UNCLOS for the peaceful and durable solution of disputes in the South China Sea. In thisconnection, the Philippines respectfully reiterates its call for China to participate in thispeaceful endeavor.1394

1119. On 22 May 2013, a spokesperson of the Chinese Foreign Ministry responded publicly to aquestion concerning the Philippines’ protest, noting as follows:
Second Thomas Shoal is part of the Nansha Islands. China’s possession of the islands andthe surrounding waters is indisputable. Official Chinese vessels have conducted normal
patrols in these waters, this cannot be questioned. China urges the countries involved tothoroughly implement the Declaration of Conduct of Parties in the South China Sea, andadmonishes these countries not to take actions which would exacerbate or complicate thedispute or to take any actions which would affect the peace and stability of the South China
Sea.1395

1120. On 28 May 2013, Major General Zhang Zhaozhong of the Chinese People’s Liberation Armygave an interview on Chinese State television and made the following comments regarding
China’s strategy at features in the South China Sea:
we have begun to take measures to seal and control the areas around the Huangyan Island[Scarborough Shoal], seal and control continuously up till now. In the over one year period
since then, there have been fishermen in the inside. Our fishermen are often there because
there is lot of fish there. Fishermen go there in large ships and then sail small boats in the
lagoon to fish. They can have shelter in the lagoon when there is a typhoon.
The fishermen conduct normal production there. In the area around the island, fishingadministration ships and marine surveillance ships are conducting normal patrols while in
the outer ring there are navy warships. The island is thus wrapped layer by layer like acabbage. As a result, a cabbage strategy has taken shape.
If the Philippines wants to go in, in the outermost area, it has first to ask whether our navy
will allow it. Then it has to ask whether our fishery administration ships and marine
surveillance ships will allow it. Therefore, our fishermen can carry out their production
safely while our country’s marine rights and interests as well as sovereignty are·safeguarded. Is that not satisfactory?
...
We should do more such things in the future. For those small islands, only a few troopers
are able to station on each of them, but there is no food or even drinking water there. If wecarry out the “cabbage” strategy, you will not be able to send food and drinking water onto
the islands. Without the supply for one or two weeks, the troopers stationed there will
leave the islands on their own. Once they have left, they will never be able to come back.
For many things, we have to grab the right timing to do them. Over the past few years, wehave made a series of achievements at the Nansha Islands (the Spratly Islands}, the greatestof which I think have been on the Huangyan Island [Scarborough Shoal], Meiji Reef
(Mischief Reef) and Ren’ai Shoal (Second Thomas Shoal).

We have gained quite satisfactory experience about the ways to recover the islands andreefs and defend them.1396

1121. On 10 June 2013, the Philippines responded to these comments by Note Verbale, reiterating its
earlier position on Second Thomas Shoal and stating further that:
The Philippines protests these statements, which it cannot help but regard as threats to use
force to prevent the Philippines from delivering essential supplies to its personnel at
Ayungin Shoal, in violation of Article 2 of the UN Charter, and Article 301 of UNCLOS,
which provides that “States Parties shall refrain from any threat or use of force against the
territorial integrity or political independence of any State, or in any other mannerinconsistent with the principles of international law embodied in the UN Charter.”
The Philippines has no obligation to notify China of its naval or other maritime activities inthe vicinity of Ayungin Shoal, or in any other area over which the Philippine is sovereignor has sovereign rights. However, in the interests of avoiding conflict, and so that its
peaceful intentions cannot be misunderstood, the Philippines hereby voluntarily notifies
China: that it will deliver essential supplies to its personnel at Ayungin Shoal this week;
that, in this instance, these supplies will be delivered by a Philippine flag ship; that the only
mission of this vessel is to deliver the essential supplies to the personnel presently situatedat Ayungin Shoal; and that this vessel has no hostile intent or purpose, and will seek toavoid contact with any Chinese vessels that may be in the vicinity.
The Philippines urges China to refrain from any hostile action to interfere with thissovereign act of the Philippine Government.
Finally, the Philippines reminds China that both States are obligated by the UN Charter and
UNCLOS to settle all disputes peacefully, and that, to this end, the Philippines has initiatedarbitration proceedings under Annex VII of UNCLOS, to obtain a peaceful, lawful anddurable settlement of the competing claims in the West Philippine Sea/South China Sea.
The Philippines, which has pledged to accept and comply with the results of theseproceedings, whatever they might be, calls upon China once again to actively participate inthese peaceful dispute settlement proceedings. 1397(b)

China’s Interference in the Rotation and Resupply of Philippine Personnel atSecond Thomas Shoal

1122. On 7 March 2014, representatives of the Philippines’ Embassy in Beijing were invited to ameeting with the Representative of the Department of Boundary and Ocean Affairs of China’s
Foreign Ministry.

As recorded by the Philippines, China’s representative conveyed thefollowing:a)

The Chinese side heard that the Philippine plans to carry out “large scaleconstruction” in Ayungin Shoal /Second Thomas shoal, “(which is) in Chinese
Nansha Islands.” (Mr. Xiao referred to Ayungin by Its Chinese name Ren’ai Reef
throughout the meeting). China expresses grave concern, and seeks someclarification. If this is true, he said, China opposes and resolutely objects suchcourse of action.

Award of 12 July 2016b)

In 1999, the Philippines illegally run aground a warship in Ayungin and
immediately China made representations and “repeatedly made representations” tothe Philippines to tow away the ship as soon as possible. The Philippines promised
China that it would tow away this ship, but it has not done so. The Philippines “hasno intention of removing this warship” and even engaged in construction. The
Philippines “has failed on its promise and has engaged in constant illegal activities.”
Last year’s “piling” and this year’s “planned construction and reinforcement” are“cases in point.”c)

The Philippines has also “distorted the fact, misguided the public and covered up thetruth.” “We believe such actions blatantly over-turned the promise of thePhilippines.” “The rhetoric and behavior of the Philippines is provocative to
China’s sovereignty and sovereign rights and China will not tolerate such.” It is also
a “severe violation of the DOC”. “China has indisputable sovereignty over theNansha Islands and adjacent waters.”d)

The Chinese side is asking the Philippines to respect China’s sovereignty andsovereign rights, tow away the grounded vessel and “put an end to any construction
work or plans” and observe its commitments. “China would never accept thePhilippines occupying Ren-ai Reef under any circumstance and in any form.”e)“If the Philippines chooses to ignore China’s major concerns and resoluteobjections, insists on construction, this would severely violate China’s sovereign
rights, push China’s bottom line, and severely undermine DOC, the peace andstability in the SCS, China will not sit idly by and tolerate. We will take resolutemeasures and actions. There will be further damage to relations. All consequences
will borne by the Philippines side.1398

1123. On 9 March 2014, two China Coast Guard vessels intercepted two Philippine vessels, which had
been dispatched by the Philippines to conduct rotation and resupply operations for personnel
stationed aboard BRP Sierra Madre, and prevented the Philippine vessels from entering Second
Thomas Shoal. As reported by the Armed Forces of the Philippines:[O]n 9:30 AM of March 9, 2014, while en route to Ayungin Shoal at the area 7.2 NM NE
off Bulig Shoal on course 055 degrees true, two (2) Chinese Coast Guard (CCG) vessels
with bow numbers 3112 and 3113 suddenly appeared and trailed them at a distance of
1,400 yards.
Thirty (30) minutes later, CCG 3113 approached the port quarter of AM700 at a distance of
400 yards while CCG 3112 approached the port beam of the civilian-contracted vessel at a
distance of 200 yards. Both CCG vessels were blocking and preventing AM700 and thecivilian-contracted watercraft from proceeding to Ayungin Shoal.
At 12:40 PM, in the area NW off Hasa-Hasa Shoal at latitude 09.223 degrees North
longitude 116.05 degrees true, CCG 3112 relayed to our vessels through digital signboard,sirens and megaphones at a distance of 1,000 yards that the CCG vessels were carrying out
routine patrols in the area, which is under the jurisdiction of the People’s Republic ofChina. Furthermore, they warned that our ships have to leave the area and should bear full
responsibility of the consequences resulting therefrom.
At 2:30PM, while the civilian-contracted vessel was avoiding contact with the CCG vessel,
the former’s engine suffered a mechanical breakdown, leaving her stranded in the water.
The AM700 provided assistance to the civilian-contracted vessel and towed her back to

Balabac, Palawan. The planned resupply and personnel rotation operations at Ayungin
Shoal were aborted due to the said incident.1399

1124. On 11 March 2014, the Philippines conveyed its protest against these actions by Note Verbale,noting in relevant part as follows:
The Department understands that China has purported to justify its actions by claiming that
the Philippine vessels were carrying “construction materials” to Ayungin Shoal. The
Philippines rejects this false accusation. Ayungin is part of the continental shelf of thePhilippines. It is, therefore, entitled to exercise sovereign rights and jurisdiction in the area
without the permission of other States. Nevertheless, in the interests of easing tensions, thePhilippines wishes to make it perfectly clear that its chartered vessels were not carrying
construction materials. To the contrary, they were merely delivering essential supplies to
the Philippine personnel stationed there and to conduct rotation of personnel.
...
China’s recent actions therefore represent a dramatic and dangerous departure from thestatus quo. As such, they constitute a flagrant, willful and material breach of Paragraph 5of the 2002 ASEAN-China Declaration on the Conduct of Parties in the South China Sea(the “DOC”), pursuant to which the signatory States, including China, specificallyundertook“to exercise self-restraint in the conduct of activities that would complicate or
escalate disputes and affect peace and stability including, among others, refraining
from action of inhabiting on the presently uninhabited islands, reefs, shoals, cays,
and other features and to handle their differences in a constructive manner.”
In addition, China’s actions constitute a clear and urgent threat to the rights and interests of
the Philippines under the 1982 United Nations Convention on the Law of the Sea (the“UNCLOS”), which are currently the subject of arbitration under Annex VII of UNCLOS.
In accordance with Articles 76 and 77 of UNCLOS, only the Philippines has sovereign
rights over the continental shelf in the area where Ayungin Shoal is located. No other Stateis lawfully entitled to assert sovereign rights or jurisdiction over said area. In this respect,
the Philippines observes that there are no insular features claimed by China in the South
China Sea capable of generating any potential entitlement in the area where Ayungin Shoal
is located.
China’s actions also constitute a grave and imminent threat to the Philippines’ right to haveits maritime dispute with China settled peacefully and in good faith, as well as its right not
to have the dispute aggravated or extended pending the outcome of the arbitration.
The Department takes note of the fact that China’s actions come just three weeks before thePhilippines is due to submit its Memorial in the aforementioned arbitration. Under the,circumstances, the Department is, regrettably, compelled to conclude that China’s conduct
at Ayungin Shoal is intended as retaliation for the Philippines’ initiative in seeking theresolution of its maritime dispute with China in accordance with international law,something the Philippines and China were unable to achieve despite years ofnegotiation.1400

The Chinese side does not accept the protest from the Philippine side. The Ren’ai reef ispart of the Nansha islands and China has indisputable sovereignty over the Nansha islands
and their adjacent waters. The Philippines grounding its warship on China’s Ren’ai reef in1999 due to so-called malfunction. The Philippines refused to honor its commitment ofpulling away the ship on the excuse of technical problems despite China’s persistent
request.
The Philippines violated the Declaration on the Conduct of Parties in the South China Sea
and severely infringed China’s sovereignty and jurisdiction over Ren’ai reef. It should bepointed out that the grounding of the Philippine ship does not constitute its occupation of
the Ren’ai reef.
China is resolute and firm in safeguarding its national sovereignty and never accepts thePhilippines’ illegal occupation of the Ren’ai reef in any form. 1401

1126. Several days later, as reported by the Philippines to the Tribunal, “the Philippines was able toprovide some essential food and water to its personnel aboard the Sierra Madre by means of an
airdrop.”1402 The Philippines noted, however, that this “is an interim solution at best, as thePhilippines still has not been able to rotate its personnel (a step which can be accomplished only
by sea), and its capacity to deliver supplies by air is limited.”1403
1127. A similar incident occurred when the Philippines attempted to resupply the BRP Sierra Madreon 29 March 2014. As reported by the Philippines to the Tribunal:
On 29 March 2014, the Philippines sent a vessel to Second Thomas Shoal to carry out the
supply and rotation of personnel aboard the BRP Sierra Madre, which has been groundedat the Shoal since 1999. The supply vessel is in the service of the Bureau of Fisheries andAquatic Resources (“BFAR”) and was selected to make the peaceful nature of its mission
clear. Nevertheless, China attempted to interdict the vessel and prevent it from carrying out
its humanitarian mission.
China’s actions on 29 March followed the same pattern as its actions on 9 March, whichwere reported in my letter dated 18 March. . . .
About an hour from the shoal, the BFAR ship was spotted by a China Coast Guard vessel,
which accelerated to approach the port side of the Philippine vessel, sounding its whistle atleast three times in the process. Very shortly thereafter, a second, larger China Coast Guard
vessel emerged, moving fast to block the path of the BFAR vessel and demanding that itturn around or “take full responsibility” for its actions. The maneuvers of the Chinese
vessels created a grave risk of collision, in violation of the Convention on the International
Regulations for Preventing Collisions at Sea, and Article 94 of the United Nations
Convention on the Law of the Sea.

In the face of these threatening actions, the smaller BF AR vessel changed course andincreased the ship’s speed to avoid the Chinese vessels. Ultimately, it was able to evadethem by navigating into the shallow water of the Shoal where the deeper-draft Chinese
ships were unable to follow. Once it had done so, the BFAR vessel completed its rotation
and resupply mission.1404

China’s Dredging, Artificial Island-Building and Construction Activities

1128. Since the commencement of the arbitration, China has greatly intensified its programme ofbuilding artificial islands and installations at Mischief Reef, Cuarteron Reef, Fiery Cross Reef,
Gaven Reef (North), Johnson Reef, Hughes Reef, and Subi Reef. The factual background to
China’s construction activities is set out in detail with respect to the Philippines’ Submission
No. 11 (see paragraphs 823 to 852 to 890 above) and Submission No. 12 (see paragraphs 996
to 1009 above). Furthermore, the environmental impacts of these activities as outlined in theFirst and Second Carpenter Reports and the Ferse Report and the Tribunal’s conclusions thereon
are set out at paragraphs 976 to 993 above.
1129. For the purposes of the present Submission, the Tribunal recalls that these Chinese activities
commenced, intensified, and were brought to the Tribunal’s attention in the period following thecommencement of the arbitration. For example on 30 July 2014, the Philippines brought to the
Tribunal’s attention the “extensive land reclamation activities” being undertaken by the Chinese
at Hughes Reef, Johnson Reef, Gaven Reef (North) and Cuarteron Reef, involving the use ofdredgers to pile sand around the reefs and expand the size of the artificial islands previously
constructed, and the addition of a landing strip at Hughes Reef. 1405 On 27 April 2015, thePhilippines advised the Tribunal that “China has recently extended its reclamation activities to
two new features: Subi Reef and Mischief Reef.”1406

THE PHILIPPINES’ POSITION
1.

Jurisdiction

1130. The Philippines submits that the Tribunal has jurisdiction to consider its Submission No. 14. It
argues that Articles 297 and 298 of the Convention do not exclude the Tribunal’s jurisdiction toconsider this Submission. In the alternative, the Philippines argues that these exceptions do not
apply to conduct that aggravates a dispute pending arbitration.1407

1131. According to the Philippines, the military activities exception in Article 298(1)(b) of theConvention does not exclude jurisdiction because the conduct relevant to paragraphs (a) to (c)of this Submission is not military in nature; rather, the activities are more appropriately
considered law enforcement activities.1408 The Philippines notes that China’s conduct at Second
Thomas Shoal “was largely carried out by CCG [China Coast Guard] and CMS vessels seeking
to enforce China’s purported ‘jurisdiction’,” and that where military vessels were used, they
were used for civilian or law enforcement purposes.1409 With regard to construction activities,
the Philippines submits that China has repeatedly stated that “their purpose was civilian, notmilitary,” and that there is no basis to conclude that they are military activities.1410 Based on its
argument that the nature and purpose of the activity must be exclusively military, to the
exclusion of all other incidental activities and purposes, the Philippines submits that the“involvement of military units in construction projects does not change their nature or
purpose.”1411
1132. The Philippines likewise argues that the exception in Article 298(1)(b) of the Convention forlaw enforcement activities does not apply.

According to the Philippines, pursuant to

Article 297(2) and (3), “the exception applies only to claims involving marine scientificresearch or fishing in the EEZ” and Submission No. 14 “addresses neither subject”, 1412 andbecause:
Second Thomas Shoal is a low-tide elevation substantially more than 12 M from any
high-tide feature. It is subject to the sovereign rights of the Philippines in respect of the
EEZ and the continental shelf. As a result, China is not “the coastal State” entitled to
invoke the law enforcement activities exception in the area of Second Thomas Shoal. 1413

1133. In the alternative, and in the event that the Tribunal considers the activities could becharacterised as military in nature, the Philippines submits that the Tribunal’s jurisdiction would
remain unaffected. The Philippines argues that China’s activities in and around Second Thomas
Shoal “give[] rise to a distinct legal dispute under, inter alia, Article 300 of the Convention,
which establishes obligations regarding good faith and abuse of rights, and out of the inherent
obligation of a party to a dispute to refrain from aggravating or extending a dispute that is

sub judice.” 1414 According to the Philippines, “the act that constitutes an aggravation or
extension of the dispute need not arise from a breach of any substantive duty under theConvention.” 1415 Accordingly, “restrictions on jurisdiction over disputes arising from thoseduties are irrelevant,” including the exceptions set out in Articles 297 and 298 of theConvention.1416 Nor is the issue of the status and entitlements, if any, that are generated byfeatures “relevant to the question of the Tribunal’s jurisdiction to determine whether China’s
activities at that feature aggravated or extended the dispute.”1417
2.

The Philippines’ Rights to Have this Dispute Settled Peacefully

1134. With respect to the merits of Submission No. 14, the Philippines submits that it has a right tohave a dispute settled peacefully, and that China is under a corresponding obligation not toaggravate or extend a dispute pending its resolution. The Philippines argues that China has
engaged in acts that have aggravated and extended the dispute.
(a)Obligation Not to Engage in Acts that Might Aggravate a Dispute

1135. The Philippines argues that China and the Philippines are required under Article 279 of theConvention to “settle any dispute between them concerning the interpretation or application ofthis Convention by peaceful means in accordance with Article 2, paragraph 3, of the Charter of
the United Nations.”1418 According to the Philippines, a “long-recognized corollary” of thisobligation “is the prohibition of any acts that might aggravate or extend the dispute.”1419 The
Philippines elaborates this obligation by reference to the “basic principles of good faith andabuse of rights” in Article 300 of the Convention, and the requirement that States Parties“behave with restraint with a view to narrowing, not widening, the differences between
them.”1420 It argues that aggravation and extension of the dispute are inconsistent with Articles
279 and 300 of the Convention.1421 Furthermore, it argues that aggravation or extension of the1414

1136. In support of this proposition, the Philippines cites the Permanent Court of International
Justice’s decision on provisional measures in Electricity Company of Sofia and Bulgaria,1423
which recognised the “universally accepted” principle that parties in a case must refrain fromaggravating the dispute. 1424 The Philippines acknowledges that this principle was articulated inconnection with a decision on provisional measures, and that this principle “is commonly
invoked in the context of provisional measures.”1425 Nonetheless, it submits that:
there is nothing in the Law of the Sea Convention or international law that limits theprinciple’s application to provisional measures, that requires a party to seek provisional
measures in order to invoke the principle, or that restricts application of the principle only
to the limited circumstances in which it may be appropriate to prescribe provisional
measures.1426

1137. In further support of the obligation to refrain from aggravation, the Philippines relies on thedecision of the International Court of Justice in United States Diplomatic and Consular Staff inTehran, 1427 the UN General Assembly’s Friendly Relations Declaration of 1970, 1428 andparagraph 5 of the DOC.1429(b)

China’s Conduct in relation to the Dispute

1138. The Philippines submits that China’s actions in and around Second Thomas Shoal and its
construction activities “violate the right of the Philippines under Article 279 of the Convention
to have this dispute settled peacefully in accordance with Article 2(3) of the U.N. Charter” aswell as the right not to have the dispute aggravated or extended.1430

1139. With respect to Second Thomas Shoal, the Philippines argues that “China has dramatically anddangerously altered the status quo pendente lite” since the commencement of this arbitration, byaggressively challenging “the long-standing presence of the Philippines at Second Thomas
Shoal” and “unlawfully preventing” the routine rotation and resupply missions “that thePhilippines has been conducting consistently since 1999.” 1431 According to the Philippines,
these actions stem from a violation of the Convention, insofar as China’s “interdiction ofPhilippine vessels navigating in the area [of Second Thomas Shoal] violates the exclusive rights
and jurisdiction appertaining to the Philippines under Articles 56 and 77 of the Convention.” 1432
The Philippines also considers that China’s actions at Second Thomas Shoal were “intended asa reprisal for the Philippines’ decision to move forward with this arbitration.”1433
1140. With respect to construction activities, the Philippines submits that China has “greatly
intensified its programme of building artificial islands and installations since thecommencement of the arbitration.”1434 The Philippines refers to satellite imagery of the sevenfeatures addressed in this part of Submission No. 14, to official government statements, and to
the findings of the expert reports referred to above which highlight the impact of these
construction activities on the ecological integrity of the South China Sea. “[A]fter thousands ofyears of development,” the Philippines notes, “these coral reefs are no longer in the condition inwhich they were found at the time this dispute was submitted to arbitration.”1435 Additionally,“[t]he direct evidence of the natural state of these features, which is relevant to several issues inthis case, has been destroyed or covered over, and this following China’s rejection of a site visitby the Tribunal.”1436 As a result, the Philippines argues, “[t]he Tribunal’s capacity to rendereffective relief has been prejudiced,” and “China has presented the Tribunal with a fait accompli
of unprecedented proportions.”1437

CHINA’S POSITION
1.

Obligation Not to Engage in Acts that Might Aggravate a Dispute

1141. In the course of these proceedings, China has on a number of occasions commented on theimportance of good faith and the duties incumbent on States Parties pursuant to the Convention.
In a letter to the individual members of the Tribunal dated 6 February 2015, the Chinese
Ambassador to the Netherlands wrote that:
China has made consistent and steadfast efforts to uphold and contribute to the international
rule of law. To uphold the international rule of law, it is essential to adhere to thefundamental principles of international law, including the principle of respecting statesovereignty and territorial integrity, which are also enshrined in the Charter of the United
Nations. On that basis, efforts should be made to maintain peace and stability in theinternational community, and promote cooperation, development and win-win results
among all countries, rather than to instigate or even exacerbate disagreements and disputes
in the name of “international rule of law”, consequently disturbing regional peace andstability.1438

1142. In its Position Paper, China recalled the principle of good faith, stating that it:
would call attention to Article 300 of the Convention, which provides that, “States Parties
shall fulfil in good faith the obligations assumed under this Convention and shall exercise
the rights, jurisdiction and freedoms recognized in this Convention in a manner which
would not constitute an abuse of right.” While being fully aware that its claims essentiallydeal with territorial sovereignty, that China has never accepted any compulsory proceduresin respect of those claims, and that there has been an agreement existing between the two
States to settle their relevant disputes by negotiations, the Philippines has neverthelessinitiated, by unilateral action, the present arbitration. This surely contravenes the relevant
provisions of the Convention, and does no service to the peaceful settlement of the
disputes.1439

1143. China also argued in its Position Paper that the Philippines has violated the principle of goodfaith in relation to the DOC:
[T]he Philippines recently called on the parties to the DOC to comply with Paragraph 5 of
the DOC and to provide “the full and effective implementation of the DOC,” in a proposal
made in its Department of Foreign Affairs statement dated 1 August 2014. This selective
and self-contradictory tactic clearly violates the principle of good faith in international law.
The principle of good faith requires all States to honestly interpret agreements they enter
into with others, not to misinterpret them in disregard of their authentic meaning in order toobtain an unfair advantage. This principle is of overriding importance and is incorporated
in Article 2(2) of the Charter of the United Nations. It touches every aspect of internationallaw (Cf. Sir Robert Jennings and Sir Arthur Watts (eds.), Oppenheim’s International Law,
9th ed., 1992, vol. 1, p. 38). In the Nuclear Tests Case, the ICJ held that, “One of the basic
principles governing the creation and performance of legal obligations, whatever theirsource, is the principle of good faith. Trust and confidence are inherent in international

2.

China’s Conduct in relation to the Dispute(a)Chinese Activities in and around Second Thomas Shoal

1144. The Tribunal notes that China has expressed its position on Second Thomas Shoal in publicstatements and diplomatic correspondence in the record. China has consistently asserted that it:
has indisputable sovereignty over the Nansha Islands, which include the Ren’ai Jiao, andthe adjacent waters. China hereby strongly protests and firmly opposes to the Philippines’
reinforcement of a military vessel illegally ‘grounded’ on the Ren’ai Jiao.” 1441

1145. In its Position Paper, China provides a more detailed explanation of its position on, and conduct
in, Second Thomas Shoal. Describing it as a “constituent part of China’s Nansha Islands,”
China asserts that:
the Philippines illegally ran a naval ship aground in May 1999 at that feature on the pretextof ‘technical difficulties’. China has made repeated representations to the Philippines,
demanding that the latter immediately tow away the vessel. The Philippines, for its part,
had on numerous occasions made explicit undertaking to China to tow away the vessel . . . .
However, for over 15 years, instead of fulfilling that undertaking, the Philippines has
attempted to construct permanent installations on Ren’ai Jiao. On 14 March 2014, thePhilippines even openly declared that the vessel was deployed as a permanent installation
on Ren’ai Jiao in 1999. China has been forced to take necessary measures in response tosuch provocative conduct.1442

1146. China has expressed two principal objections to the conduct of the Philippines in Second
Thomas Shoal. First, it objects to the Philippines’ refusal “to fulfill its commitment of towing
away the vessel.”1443 Second, China alleges that the Philippines has “aggravate[d] the situation
by carrying out illegal activities in an attempt to permanently occupy the Ren’ai Jiao.”1444 As it
states in its Position Paper:
In recent years, the Philippines has repeatedly taken new provocative actions in respect of. . . Ren’ai Jiao. Such actions have gravely hindered mutual political trust between China
and the Philippines.1445

China’s Dredging and Construction Activities

1147. In relation to what a spokesperson of China’s Foreign Ministry has referred to as “the land
reclamation project of China’s construction on some stationed islands and reefs of theNansha Islands,” China has consistently argued that its activities are “reasonable, justified andlawful,” and within its sovereignty. 1446 China notes that its “indisputable sovereignty overNansha Islands and their adjacent waters” includes Mischief Reef and Fiery Cross Reef, among
others.1447
1148. In June 2015, the Foreign Ministry Spokesperson noted that:[t]he construction activities . . . are not targeted at any other country, do not affect the
freedom of navigation and overflight enjoyed by all countries in accordance withinternational law in the South China Sea, nor have they caused or will they cause damage tothe marine ecological system and environment in the South China Sea. . . .1448

1149. As discussed above in relation to the Philippines’ Submissions No. 11 and 12, China hasrepeatedly stated publicly that the predominant purpose of its construction activities is civilian
in nature. 1449 China’s Foreign Ministry Spokesperson described the “main purpose” of theactivities as:
meet[ing] various civilian demands and better perform[ing] China’s international
obligations and responsibilities in the areas such as maritime search and rescue, disasterprevention and mitigation, marine scientific research, meteorological observation,
ecological environment conservation, navigation safety as well as fishery production
service. After the land reclamation, we will start the building of facilities to meet relevant
functional requirements.1450

The South China Sea Arbitration
Award of 12 July 2016

1151. In its Award on Jurisdiction, the Tribunal held that Submission No. 14, then in its unamended
form, reflected a dispute concerning “China’s activities in and around Second Thomas Shoal
and China’s interaction with the Philippine military forces stationed on the Shoal.” 1451
According to the Tribunal, “[t]his is not a dispute concerning sovereignty or maritime boundary
delimitation, nor is it barred from the Tribunal’s consideration by any requirement of Section 1of Part XV.” 1452 However, the Tribunal noted that its jurisdiction to address the questions
relating to Submission No. 14 “may depend on the status of Second Thomas Shoal as an‘island’, ‘rock’, or ‘low-tide elevation’.” 1453

The Tribunal also noted the exclusion in

Article 298(1)(b) for disputes concerning military activities and considered that “the specifics ofChina’s activities in and around Second Thomas Shoal and whether such activities are military
in nature to be a matter best assessed in conjunction with the merits.”
1152. The Tribunal thus reserved any final decision on its jurisdiction with respect toSubmission No. 14 for further consideration in this Award.1454 The Tribunal also notes that thePhilippines’ amendment of its claims to include Submission No. 14(d) took place following the
Tribunal’s Award on Jurisdiction and that the Tribunal has not yet considered its jurisdiction in
respect of the Philippines’ amended claim.
(a)China’s Actions in and around Second Thomas Shoal

1153. As set out above, the Tribunal has now found that Second Thomas Shoal is a low-tide elevation(see paragraphs 379 to 381) and, as such, generates no entitlement to maritime zones of its own.
The Tribunal has also found that none of the high-tide features in the Spratly Islands is a fully
entitled island for the purposes of Article 121 of the Convention (see paragraphs 473 to 647
above). The Tribunal has also found that there are no high-tide features within 12 nautical milesof Second Thomas Shoal (see paragraph 632 above). From these conclusions, it follows that
there exists no legal basis for any entitlement by China to maritime zones in the area of Second
Thomas Shoal. There is as a result no situation of overlapping entitlements that would call forthe application of Articles 15, 74, or 83 to delimit the overlap. Nor is there any need to address
sovereignty over Second Thomas Shoal before the Tribunal may consider China’s actions there.
Second Thomas Shoal is a low-tide elevation located within the exclusive economic zone of thePhilippines.

1154. However, the Tribunal’s jurisdiction is still contingent on the application of the militaryactivities exception in Article 298(1)(b) of the Convention. That exception provides as follows:
When signing, ratifying or acceding to this Convention or at any time thereafter, a State
may, without prejudice to the obligations arising under section 1, declare in writing that it
does not accept any one or more of the procedures provided for in section 2 with respect toone or more of the following categories of disputes:...
(b)

disputes concerning military activities, including military activities by government
vessels and aircraft engaged in non-commercial service . . . .

China activated this exception through its August 2006 Declaration.1455
1155. On its face, Article 298(1)(b) excludes the consent of any State Party making such a declarationin respect of any dispute concerning military activities. The Tribunal notes, however, that thePhilippines has advanced two limitations that it considers to restrict the scope of
Article 298(1)(b) and render it inapplicable in the present proceedings.
1156. First, the Philippines argues that “[t]he decision to rely on those options is a matter of choice,both at the declaration stage and thereafter.

A respondent is not required to insist on ajurisdiction exception covered by a declaration.”

1456

The Tribunal understands the Philippines’

position to be that if China has not specifically invoked Article 298(1)(b) in the course of theseproceedings, the Tribunal need look no further into the application of this provision. The
Tribunal, however, cannot agree with this proposition. Article 298(1) provides for a State Party
to “declare in writing that it does not accept” a form of compulsory dispute resolution withrespect to one or more of the enumerated categories of disputes. This formulation stands instark contrast to the more optional formulation employed in Article 297(2) and 297(3), which
provide that a State Party “shall not be obliged to accept the submission” of a dispute tocompulsory settlement. In contrast to an objection under Article 297, the Tribunal sees nothing
to suggest that a provision of Article 298(1) must be specifically invoked. Once made, adeclaration under Article 298(1) excludes the consent of the declaring State to compulsory
settlement with respect to the specified categories of disputes. Article 299(1) then expressly
provides in unequivocal terms that “[a] dispute . . . excepted by a declaration made underarticle 298 from the dispute settlement procedures provided for in section 2 may be submitted tosuch procedures only by agreement of the parties to the dispute.” Such a declaration stands
until modified or withdrawn. The absence of any mention of Article 298(1)(b) from China’s

454

The South China Sea Arbitration

Position Paper and public statements does not obviate the Tribunal’s need to consider theapplicability of this provision.
1157. Second, the Philippines argues that “Articles 297 and 298 do not apply to aggravation andextension of the dispute.” 1457 According to the Philippines, “Submission 14 addresses only
breaches of [China’s] obligation [to refrain from aggravating or extending the dispute] that
occurred after the dispute was submitted to this Tribunal.

Jurisdiction over the disputeoriginally submitted to the Tribunal is the only requirement for jurisdiction over thissubmission.

Articles 297 and 298 are inapplicable.” 1458

The Tribunal understands thisargument to be that, insofar as any obligation not to aggravate the dispute concerns events
subsequent to the commencement of proceedings, it is not separately subject to the limitations
on dispute resolution set out in the Convention. Rather, these limitations apply to the disputethat is alleged to have been aggravated.
1158. In this respect, the Tribunal notes that Article 298(1)(b) applies to “disputes concerning militaryactivities” and not to “military activities” as such. Accordingly, the Tribunal considers therelevant question to be whether the dispute itself concerns military activities, rather thanwhether a party has employed its military in some manner in relation to the dispute. Where aState Party has initiated compulsory dispute settlement under the Convention in respect of adispute that does not concern military activities, Article 298(1)(b) would not come into play if
the other Party were later to begin employing its military in relation to the dispute in the courseof proceedings. Nor does the Tribunal see that Article 298(1)(b) would limit its ancillary
jurisdiction to prescribe provisional measures in respect of military activities taking place inrelation to a dispute that does not, itself, concern military activities.
1159. Where the aggravation of the dispute is alleged not in connection with a request for provisional
measures, but—as in the present case—as a substantive claim, the Tribunal finds it necessary toconsider whether the claim of aggravation remains dependent on an underlying dispute, orwhether it constitutes itself a distinct dispute to which the military activities exception would beapplicable. The Tribunal notes that the Philippines has never clearly identified the dispute thatit considers to have been aggravated by China’s actions at Second Thomas Shoal. Rather, whenpressed to elaborate on the existence of a dispute, the Philippines argued that China’s
interference with navigation and prevention of the rotation and resupply of Philippines troops“gives rise to a distinct legal dispute under, inter alia, Article 300 of the Convention, which
establishes obligations regarding good faith and abuse of rights, and out of the inherent

obligation of a party to a dispute to refrain from aggravating or extending a dispute that is sub
judice.”1459 The Tribunal likewise held in its Award on Jurisdiction that “Submission No. 14
reflects a dispute concerning China’s activities in and around Second Thomas Shoal andChina’s interaction with the Philippine military forces stationed on the Shoal.”1460
1160. It follows that China’s actions in and around Second Thomas Shoal and its interaction with thePhilippine military forces stationed there constitute a distinct matter, irrespective of their effectin potentially aggravating other disputes before the Tribunal. The Tribunal considers that it
must evaluate whether this dispute concerns military activities for the purposes of
Article 298(1)(b).
1161. On the basis of the record set out above, the Tribunal finds that the essential facts at Second
Thomas Shoal concern the deployment of a detachment of the Philippines’ armed forces that is
engaged in a stand-off with a combination of ships from China’s Navy and from China’s Coast
Guard and other government agencies. In connection with this stand-off, Chinese Government
vessels have attempted to prevent the resupply and rotation of the Philippine troops on at least
two occasions. Although, as far as the Tribunal is aware, these vessels were not military
vessels, China’s military vessels have been reported to have been in the vicinity.

In theTribunal’s view, this represents a quintessentially military situation, involving the militaryforces of one side and a combination of military and paramilitary forces on the other, arrayed in
opposition to one another. As these facts fall well within the exception, the Tribunal does notconsider it necessary to explore the outer bounds of what would or would not constitute militaryactivities for the purposes of Article 298(1)(b).
1162. Accordingly, the Tribunal finds that it lacks jurisdiction to consider the Philippines’
Submissions No. 14(a) to (c).
(b)

China’s Dredging and Construction Activities

1163. The Tribunal has already discussed its jurisdiction with respect to China’s dredging, artificial
island-building, and construction activities at Cuarteron Reef, Fiery Cross Reef, Johnson Reef,
Hughes Reef, Gaven Reef (North), Subi Reef, and Mischief Reef in connection with the mattersraised in the Philippines’ Submissions No. 11 and 12 (see paragraphs 925 to 938 and 1024
to 1028 above).

1164. For the reasons already set out, the Tribunal will not find activities to be military in nature when
China itself has consistently resisted such classification and affirmed the opposite at the highest
level. Accordingly, the Tribunal accepts China’s repeatedly affirmed position that civilian use
comprises the primary (if not the only) motivation underlying its works on the aforementioned
features. As civilian activity, the Tribunal notes that China’s conduct falls outside the scope of
Article 298(1)(b) in any event. Accordingly, for the purposes of its jurisdictional analysis, theTribunal need not engage with the question of whether the Philippines’ Submission No 14(d)constitutes a distinct dispute from those the Philippines alleges to have been aggravated or
extended.
1165. The Tribunal concludes that it has jurisdiction with respect to the matters raised in thePhilippines’ Submission No. 14(d). The Tribunal now turns to the activities underpinning thisportion of the Philippines’ claim.
2.

The Law Applicable to Conduct in the Course of Dispute Resolution Proceedings

1166. The Philippines’ claim that China, through its dredging, artificial island-building, andconstruction activities, has acted to aggravate and extend the dispute between the Parties,
requires the Tribunal to consider the law applicable to the conduct of parties in the course of
dispute resolution proceedings.
1167. In this respect, the Tribunal recalls the point made by the Permanent Court of International
Justice in Electricity Company of Sofia and Bulgaria. In that matter, the Court was requested
by Belgium to indicate provisional measures pursuant to Article 41 of its Statute to order thatcertain municipal court proceedings be suspended pending the resolution of the internationalcase. The Court noted that Article 41 of its Statute:
applies the principle universally accepted by international tribunals and likewise laid down
in many conventions . . . to the effect that the parties to a case must abstain from any
measure capable of exercising a prejudicial effect in regard to the execution of the decision
to be given and, in general, not allow any step of any kind to be taken which might
aggravate or extend the dispute.1461

The Court then went on to direct Bulgaria to “ensure that no step of any kind is taken capable ofprejudicing the rights claimed by the Belgian Government or of aggravating or extending the
dispute submitted to the Court.”1462

457

The South China Sea Arbitration
Award of 12 July 2016

1168. The same principle was recognised by the International Court of Justice in LaGrand as
underpinning its power to indicate provisional measures and as evidence of the binding
character of orders issued pursuant to Article 41 of the Court’s Statute.1463 Additionally, theInternational Court of Justice has frequently issued provisional measures directing the parties torefrain from any actions which could aggravate or extend the dispute 1464 and has done so
notwithstanding that Article 41 of its Statute expressly refers only to measures “to preserve therespective rights of either party.”1465 In so doing, the Court has indicated that “independently of
the requests for the indication of provisional measures submitted by the Parties to preserve
specific rights, the Court possesses by virtue of Article 41 of the Statute the power to indicate
provisional measures with a view to preventing the aggravation or extension of the dispute
whenever it considers that circumstances so require.”1466 The International Tribunal for the Lawof the Sea has likewise directed parties to “pursue cooperation and refrain from any unilateral
action that might lead to aggravating the dispute” when ordering provisional measures under
Article 290(1) of the Convention.1467
1169. In the Tribunal’s view, the proper understanding of this extensive jurisprudence on provisional
measures is that there exists a duty on parties engaged in a dispute settlement procedure torefrain from aggravating or extending the dispute or disputes at issue during the pendency of the1463

jurisprudence, however, the Court has noted that it has consistently indicated measures directing theparties to refrain from actions that would aggravate or extend the dispute in conjunction with otherprovisional measures and found no need to address potential aggravation when it found that othermeasures were not warranted.

Award of 12 July 2016settlement process. This duty exists independently of any order from a court or tribunal torefrain from aggravating or extending the dispute and stems from the purpose of disputesettlement and the status of the States in question as parties in such a proceeding. Indeed, whena court or tribunal issues provisional measures directing a party to refrain from actions thatwould aggravate or extend the dispute, it is not imposing a new obligation on the parties, butrather recalling to the parties an obligation that already exists by virtue of their involvement in
the proceedings.
1170. Recognition of a duty to refrain from aggravating or extending a dispute during settlement
proceedings is also apparent in the widespread inclusion of express provisions to such effect inmultilateral conventions providing for the settlement of disputes 1468 and its nearly routine
inclusion in bilateral arbitration and conciliation treaties. 1469 Such a duty has also been
underlined by the General Assembly of the United Nations in its Friendly Relations Declaration,
which provides:
States parties to an international dispute, as well as other States shall refrain from any
action which may aggravate the Situation so as to endanger the maintenance ofinternational peace and security, and shall act in accordance with the purposes andprinciples of the United Nations.1470

1171. In the Tribunal’s view, such a duty is inherent in the central role of good faith in theinternational legal relations between States. Article 26 of the Vienna Convention on the Law ofTreaties recognises this when it provides that “[e]very treaty in force is binding upon the parties
to it and must be performed by them in good faith.”1471 This obligation is no less applicable tothe provisions of a treaty relating to dispute settlement. Where a treaty provides for the1468

1469

The Tribunal notes the inclusion of such a provision in well over 50 bilateral arbitration conventions
concluded between a variety of different States. See, e.g., Treaty for Conciliation, Judicial Settlement andArbitration between the United Kingdom of Great Britain and Northern Ireland and Switzerland, art. 31,
7 July 1965, 605 UNTS 205; Treaty between Brazil and Venezuela for the Pacific Settlement of Disputes,

compulsory settlement of disputes, the good faith performance of the treaty requires thecooperation of the parties with the applicable procedure.

Compulsory settlement is alsopremised on the notion that the final result will be binding on the parties and implemented bythem as a resolution of their dispute. The very purpose of dispute settlement procedures would
be frustrated by actions by any party that had the effect of aggravating or extending the dispute,
thereby rendering it less amenable to settlement.
1172. Within the Convention, the same principles find expression in Article 279, which provides that:
States Parties shall settle any dispute between them concerning the interpretation orapplication of this Convention by peaceful means in accordance with Article 2,paragraph 3, of the Charter of the United Nations and, to this end, shall seek a solution by
the means indicated in Article 33, paragraph 1, of the Charter.

In carrying out the dispute settlement procedures of the Convention, the Parties are also underan obligation, pursuant to Article 300, to “fulfil in good faith the obligations assumed under thisConvention and . . . exercise the rights, jurisdiction and freedoms recognized in this Convention
in a manner which would not constitute an abuse of right.”1472 Finally, the Tribunal considers
that the final and binding nature of the Award has an impact on the permissible conduct of theparties in the course of proceedings. Article 296 of the Convention provides that “[a]ny
decision rendered by a court or tribunal having jurisdiction under this section shall be final andshall be complied with by all the parties to the dispute”; Article 11 of Annex VII to theConvention provides that “[t]he award shall be final and without appeal, unless the parties to thedispute have agreed in advance to an appellate procedure. It shall be complied with by theparties to the dispute.” The Tribunal concludes that actions by either Party to aggravate or
extend the dispute would be incompatible with the recognition and performance in good faith ofthese obligations.
1173. In the Tribunal’s view, there is no need to reach beyond the text of the Convention to identify
the source of the law applicable to the conduct of parties in the course of dispute settlement
proceedings under Part XV. To the extent that it were necessary to do so, however, the Tribunal
considers, for the reasons set out above, that the duty to “abstain from any measure capable ofexercising a prejudicial effect in regard to the execution of the decision to be given and, ingeneral, not allow any step of any kind to be taken which might aggravate or extend thedispute”1473 constitutes a principle of international law that is applicable to States engaged in
dispute settlement as such. Pursuant to Article 293 of the Convention, this principle constitutes

one of the “other rules of international law not incompatible with this Convention” to which the
Tribunal may have recourse.1474
3.

The Effect of China’s Dredging and Construction Activities on the Parties’ Disputes

1174. Having found that the Convention and other rules of international law binding on the Parties
impose a duty to refrain from aggravating or extending the dispute pending the completion of
dispute resolution proceedings, the Tribunal considers that a necessary first step is to identify
clearly the dispute that is alleged to have been aggravated or extended. Neither the Convention,
nor international law, go so far as to impose a legal duty on a State to refrain from aggravating
generally their relations with one another, however desirable it might be for States to do so.
Actions must have a specific nexus with the rights and claims making up the parties’ dispute inorder to fall foul of the limits applicable to parties engaged in the conduct of dispute resolution
proceedings.
1175. In the Tribunal’s view, China’s dredging, artificial island-building, and construction activities at
Cuarteron Reef, Fiery Cross Reef, Johnson Reef, Hughes Reef, Gaven Reef (North), Subi Reef,
and Mischief Reef bear on a number of the disputes submitted by the Philippines for resolution
in these proceedings:(a)First, the Philippines has put before this Tribunal a dispute concerning the status andentitlements of a number of features in the South China Sea that are presently under thecontrol of China. This is reflected in the Philippines’ Submissions No. 4, 6, and 7. As
discussed in connection with the Tribunal’s consideration of those Submissions (seeparagraphs 305 to 306, 321, 511, 541, and 578 above), China’s dredging, artificial islandbuilding, and construction activities has had the effect of obscuring evidence of thenatural status of those features.

(b)Second, the Philippines has put before the Tribunal a series of disputes concerning theParties’ respective entitlements to maritime zones and corresponding rights under theConvention in the area of Mischief Reef. These disputes are reflected in the Philippines’
Submissions No. 5, 8, 9, and 12.

China’s dredging, artificial island-building, andconstruction activities have had the effect of obscuring evidence of the natural status of
Mischief Reef, which is in turn determinative of the Parties’ potential rights in the area.
Additionally, as the Tribunal has found that Mischief Reef is a low-tide elevation locatedon the continental shelf of the Philippines, China’s construction there of a very large
1474

Convention, art. 293.

461

The South China Sea Arbitration
Award of 12 July 2016

artificial island has an effect on the implementation of the Tribunal’s decision and thePhilippines’ future exercise of its sovereign rights in the area of Mischief Reef.
(c)

Third, the Philippines has put before the Tribunal a dispute concerning the protection andpreservation of the marine environment at Scarborough Shoal, Second Thomas Shoal,
Cuarteron Reef, Fiery Cross Reef, Gaven Reef (North), Johnson Reef, Hughes Reef, Subi
Reef, and Mischief Reef.

China’s construction at seven of these features of large

artificial islands, covering significant portions of the reef platform, has an effect on theimplementation of the Tribunal’s decision and the practical possibility of avoiding harmto the marine environment.
1176. In the course of dispute resolution proceedings, the conduct of either party may aggravate a
dispute where that party continues during the pendency of the proceedings with actions that are
alleged to violate the rights of the other, in such a way as to render the alleged violation more
serious. A party may also aggravate a dispute by taking actions that would frustrate theeffectiveness of a potential decision, or render its implementation by the parties significantly
more difficult. Finally, a party may aggravate a dispute by undermining the integrity of the
dispute resolution proceedings themselves, including by rendering the work of a court or
tribunal significantly more onerous or taking other actions that decrease the likelihood of theproceedings in fact leading to the resolution of the parties’ dispute.
1177. The Tribunal considers that China’s intensified construction of artificial islands on sevenfeatures in the Spratly Islands during the course of these proceedings has unequivocally
aggravated the disputes between the Parties identified above. First, China has effectively
created a fait accompli at Mischief Reef by constructing a large artificial island on a low-tide
elevation located within the Philippines’ exclusive economic zone and continental shelf, an area
in which only the Philippines has sovereign rights with respect to living and non-living
resources and where only the Philippines may construct or authorise artificial islands. In
practical terms, the implementation of the Tribunal’s decision will be significantly moredifficult for the Parties, and Mischief Reef cannot be returned to its original state, before
China’s construction work was begun.
1178. Second, China has aggravated the Parties’ dispute with respect to the protection andpreservation of the marine environment by causing irreparable harm to the coral reef habitat at
Cuarteron Reef, Fiery Cross Reef, Gaven Reef (North), Johnson Reef, Hughes Reef, Subi Reef,
and Mischief Reef. The Tribunal has already found that China has seriously violated its
obligation to preserve and protect the marine environment in the South China Sea (seeparagraphs 950 to 993 above). Whatever other States have done within the South China Sea, it
462

The South China Sea Arbitration
Award of 12 July 2016

pales in comparison to China’s recent construction. In practical terms, neither this decision nor
any action that either Party may take in response can undo the permanent damage that has been
done to the coral reef habitats of the South China Sea. In this respect, the Tribunal is consciousthat the marine environment at Cuarteron Reef, Fiery Cross Reef, Gaven Reef (North), Johnson
Reef, Hughes Reef, and Subi Reef did not form part of the Philippines’ claims in theseproceedings prior to the close of the November 2015 hearing. In the Tribunal’s view, China’s
actions have aggravated the dispute between the Parties with respect to the marine environment
at Mischief Reef and extended that dispute to encompass additional features that became thesites of large-scale construction work while this arbitration was ongoing.
1179. Finally, China has undermined the integrity of these proceedings and rendered the task before
the Tribunal more difficult. At the same time that the Tribunal was called upon to determine thestatus of features in the Spratly Islands and the entitlements that such features were capable ofgenerating, China has permanently destroyed evidence of the natural status of those samefeatures (see paragraphs 305 to 306, 321, 511, 541, and 578 above). The small rocks and sandcays that determine whether a feature constitutes a low-tide elevation or a high-tide featurecapable of generating an entitlement to a territorial sea are now literally buried under millions oftons of sand and concrete. Despite this, the Tribunal has reached a decision on the status offeatures in the South China Sea using the best evidence available to it and drawing heavily on
historical sources. The Tribunal is satisfied that its decisions regarding the status of features arewell founded in fact, but records that they were rendered significantly more difficult by China’s
works at the features in question.
1180. The Tribunal notes China’s consistent position that it will not participate in these proceedings
and its view that “non-participation in the present arbitration is solidly grounded in internationallaw.”1475 China has also continued to reject the jurisdiction of this Tribunal, notwithstanding thedecisions reached in the Tribunal’s Award on Jurisdiction. 1476 The Tribunal recalls that
Article 9 of Annex VII to the Convention anticipates the possibility that a party may not appear
before the arbitral tribunal. However, the Convention also provides that “[i]n the event of adispute as to whether a court or tribunal has jurisdiction, the matter shall be settled by decision

considered most appropriate, including by refraining from any formal appearance, as it has infact done. The decision of how best to represent China’s position is a matter for China, not the
Tribunal. China is not free, however, to act to undermine the integrity of these proceedings or
to frustrate the effectiveness of the Tribunal’s decisions.

The Convention and generalinternational law limit the actions a party may take in the course of ongoing dispute resolution
proceedings. China has fallen short of its obligations in this respect.

Conclusion

1181. Based on the considerations outlined above, the Tribunal finds that China has in the course of
these proceedings aggravated and extended the disputes between the Parties through its
dredging, artificial island-building, and construction activities.

In particular, while theseproceedings were ongoing:(a)

China has aggravated the Parties’ dispute concerning their respective rights andentitlements in the area of Mischief Reef by building a large artificial island on a low-tide
elevation located in the exclusive economic zone of the Philippines.

(b)

China has aggravated the Parties’ dispute concerning the protection and preservation of
the marine environment at Mischief Reef by inflicting permanent, irreparable harm to thecoral reef habitat of that feature.

(c)

China has extended the Parties’ dispute concerning the protection and preservation of themarine environment by commencing large-scale island-building and construction works
at Cuarteron Reef, Fiery Cross Reef, Gaven Reef (North), Johnson Reef, Hughes Reef,and Subi Reef.

(d)China has aggravated the Parties’ dispute concerning the status of maritime features in the
Spratly Islands and their capacity to generate entitlements to maritime zones bypermanently destroying evidence of the natural condition of Mischief Reef, Cuarteron
Reef, Fiery Cross Reef, Gaven Reef (North), Johnson Reef, Hughes Reef, and Subi Reef.

THE FUTURE CONDUCT OF THE PARTIES (SUBMISSION NO. 15)1182. In this Chapter, the Tribunal addresses the Philippines’ Submission No. 15, which requests the
Tribunal to adjudge and declare that:(15)

China shall respect the rights and freedoms of the Philippines under the Convention,
shall comply with its duties under the Convention, including those relevant to theprotection and preservation of the marine environment in the South China Sea, andshall exercise its rights and freedoms in the South China Sea with due regard to
those of the Philippines under the Convention.

1183. As originally framed, the Philippines’ Submission No. 15 requested a declaration that “China
shall desist from further unlawful claims and activities.”1479 In its Award on Jurisdiction, theTribunal noted that the claims and activities to which the original Submission could potentiallyrelate were unclear. Thus the Tribunal held that it was unable at the time to determine whether
a dispute existed “between the Parties concerning the interpretation or application of theConvention or to assess the scope of the Tribunal’s jurisdiction in this respect.” 1480
Accordingly, the Tribunal directed the Philippines “to clarify the content and narrow the scopeof its Submission No. 15” and reserved the question of its jurisdiction in relation to Submission
No. 15 for consideration in conjunction with the merits of the Philippines’ claims.1481
1184. The Philippines reframed its Submission at the Hearing on the Merits and in subsequentcorrespondence.

The Tribunal granted leave to the Philippines to amend its Submission

accordingly, noting that the proposed amendment was related to or incidental to the Philippines’
original Submission and did not involve the introduction of a new dispute between theParties.1482
A.

THE PHILIPPINES’ POSITION

1185. The Philippines observes that “[t]he focus of this submission is prospective.”1483 According to
the Philippines, the record of China’s “significant, persistent and continuing violations” of thePhilippines’ rights under the Convention, and China’s “statements and conduct in this regard
provide ample justification for ordering China to respect the rights and freedoms of thePhilippines in the future, and to honour its environmental obligations.”1484

1186. The Philippines links its Submission No. 15 to the requirement of “due regard”, which it argues
is “one of the basic organising principles” of the Convention and should be given “broad
application.”1485 The Philippines provides as examples of China’s failure to show due regard to
the Philippines’ rights China’s attempts to prevent Philippine fishing or hydrocarbon activities
in areas within 200 miles of the Philippines, as well as the conduct by China of its own activities
within that area.1486
1187. The Philippines concentrated its arguments about Submission No. 15 on the hypotheticalsituation that would result from the Tribunal finding any of the Spratly features to be fully
entitled islands under Article 121 of the Convention, and the uncertainty, tension and “perverse
effects” that would potentially result from such a finding.1487 It reflected on the “chaos andinsecurity” that had resulted in the past year and a half from “unilateral actions in the absence ofa precisely defined legal order.”1488
1188. With respect to the Tribunal’s jurisdiction to address the issues described in connection with
Submission No. 15, the Philippines argued there are “no obstacles”. It acknowledges that due toChina’s invocation of Article 298’s exclusion for sea boundary delimitation, “the Tribunal could
not proceed to delimit any areas of overlapping entitlements.” However, the Philippines statesthat “the Tribunal would retain jurisdiction in respect of the rights and obligations of the parties
in the area of overlap pending such a delimitation.”1489 The Philippines explains:[P]aragraph 3 of Articles 74 and 83 is not a delimitation provision to which
Article 298(1)(a) applies. Rather, the paragraph invites the structuring of a binding code of
conduct pending delimitation of overlapping entitlements. As such, that paragraph 3 is a
specific manifestation of the obligation to settle disputes peacefully, set forth in
Article 279, and of the prohibition on abuse of rights set forth in Article 300.
Paragraph 1(a) of Article 298 does not apply to those articles either; they are notspecifically mentioned, and they are not delimitation provisions. 1490

B.

CHINA’S POSITION

1189. China has not directly stated its position with respect to Submission No. 15 as amended.
1190. The Tribunal has already noted however, in respect of Submission No. 14, that in the course of
these proceedings, Chinese officials have made a number of statements on the importance of

good faith and the duties incumbent on States pursuant to the Convention.1491 For example, thePosition Paper emphasised that, pursuant to Article 300 of the Convention, States Parties shall“exercise the rights, jurisdiction and freedoms recognized in this Convention in a manner which
would not constitute an abuse of right.”1492 More recently, on 19 May 2016, China’s Foreign
Minister Wang Yi spoke of China acting in accordance with law and “safeguarding the sanctityof the UNCLOS.”1493
C.

THE TRIBUNAL’S CONSIDERATIONS

1191. There are three components to the Philippines’ Submission No. 15 as amended.
1192. First, the Tribunal is asked to adjudge and declare that China shall respect the rights andfreedoms of the Philippines under the Convention.
1193. Second, the Tribunal is asked to adjudge and declare that China shall comply with its duties
under the Convention, including those relevant to the protection and preservation of the marine
environment in the South China Sea.
1194. Third, the Tribunal is asked to adjudge and declare that China shall exercise its rights andfreedoms in the South China Sea with due regard to those of the Philippines under theConvention.
1195. All of these propositions fall within the basic rule of “pacta sunt servanda”, expressed in
Article 26 of the Vienna Convention on the Law of Treaties as: “Every treaty in force isbinding upon the parties to it and must be performed by them in good faith.” In essence, what
the Philippines is requesting is a declaration from the Tribunal that China shall do what it isalready obliged by the Convention to do.
1196. As both Parties have pointed out, the Convention itself expresses in Article 300 that:
States Parties shall fulfil in good faith the obligations assumed under this Convention andshall exercise the rights, jurisdiction and freedoms recognized in this Convention in amanner which would not constitute an abuse of right.

The South China Sea Arbitration
Award of 12 July 2016

1197. The Tribunal accepts that various provisions of the Convention make clear that States are undera duty to resolve their disputes peacefully,1494 and that States are under a general duty to have“due regard” to the rights and obligations of other States.1495
1198. There is, however, no dispute between the Parties that these general obligations define andregulate their conduct. The root of the disputes presented by the Philippines in this arbitration
lies not in any intention on the part of China or the Philippines to infringe on the legal rights of
the other, but rather—as has been apparent throughout these proceedings—in fundamentallydifferent understandings of their respective rights under the Convention in the waters of theSouth China Sea. In such circumstances, the purpose of dispute resolution proceedings is toclarify the Parties’ respective rights and obligations and thereby to facilitate their future
relations in accordance with the general obligations of good faith that both governments
unequivocally recognise.
1199. To the extent that the matters presented by the Philippines have fallen within its jurisdiction, theTribunal has already acted, through this Award, to clarify the Parties’ respective rights andobligations in the South China Sea. The Tribunal notes that much of the Philippines’ concern
reflected in Submission No. 15 that “chaos and insecurity” will result from “unilateral actions in
the absence of a precisely defined legal order”1496 is connected with the hypothetical situation ofpotentially overlapping entitlements to maritime zones and the absence of an interim regime
pending the delimitation of a maritime boundary. The Tribunal’s findings with respect toSubmissions No. 3, 5, and 7, however, and its conclusion that there is no possible overlap ofentitlements that would require delimitation, render that concern purely hypothetical and nobasis for further action by the Tribunal.
1200. Going forward, it is a fundamental principle of international law that “bad faith is notpresumed,”1497 and Article 11 of Annex VII provides that the “award . . . shall be complied withby the parties to the dispute.”1498 It goes without saying that both Parties are obliged to resolve
their disputes peacefully and to comply with the Convention and this Award in good faith.

CONCLUSION

1201. The Tribunal considers it beyond dispute that both Parties are obliged to comply with theConvention, including its provisions regarding the resolution of disputes, and to respect therights and freedoms of other States under the Convention. Neither Party contests this, and the
Tribunal is therefore not persuaded that it is necessary or appropriate for it to make any further
declaration.
