 The Spratly Islands dispute is an ongoing territorial dispute between Brunei, China, Malaysia, the Philippines, Taiwan, and Vietnam concerning "ownership" of the Spratly Islands, a group of islands and associated "maritime features" (reefs, banks, and cays etc.) located in the South China Sea. The dispute is characterized by diplomatic stalemate and the employment of military pressure techniques (such as military occupation of disputed territory) in the advancement of national territorial claims. All except Brunei occupy some of the maritime features.
 Most of the "maritime features" in this area have at least six names: The "international name", usually in English; the "Chinese name", sometimes different for PRC and ROC (and also in different character-sets); the Philippine, Vietnamese and Malaysian names, and also, there are alternate names (e.g. Spratly Island is also known as Storm Island), and sometimes names with European origins (French, Portuguese, Spanish, British, etc.).
 Although not large, reserves of oil and natural gas have been found in the area. It is a commercial fishing ground and close to global shipping routes. Its strategic position allows countries to monitor maritime activities in the area and project military power. The Philippines claims part of the area as its territory under UNCLOS, an agreement parts of which have been ratified by the countries involved in the Spratly islands dispute. However, China (PRC), Taiwan (ROC), and Vietnam are the only ones to have made claims based on historical sovereignty of the islands.
 In 1968, oil was discovered in the region. On 11 March 1976, the first major Philippine oil discovery occurred off the coast of Palawan, near the Spratly Islands territory. In 2010, these oil fields supplied 15% of all petroleum consumed in the Philippines. In 1992, the PRC and Vietnam granted oil exploration contracts to US oil companies that covered overlapping areas in the Spratlys. In May 1992, the China National Offshore Oil Corporation (CNOOC) and Crestone Energy (a US company based in Denver, Colorado) signed a co-operation contract for the joint exploration of the Wan'an Bei-21 block, a 25,155 square kilometres (9,710 sq mi) section of the southwestern South China Sea that includes Spratly Island areas.
 In 2012-2013, the United States Energy Information Administration estimates very little oil and natural gas in contested areas such as the Paracels and the Spratly Islands. Most of the proved or probable 11 billion barrels of oil and 190 trillion cubic feet of natural gas in the South China Sea exist near undisputed shorelines.
 In 2010, the Western Central Pacific (excluding the northernmost reaches of the South China Sea closest to the PRC coast) accounted for 14% of the total world catch at 11.7 million tonnes. This was up from less than 4 million tonnes in 1970. In 1984, Brunei established an exclusive fishing zone encompassing Louisa Reef in the southeastern Spratly Islands.
 The area is close to some of the busiest shipping lanes in the world, accounting for 3.4 of the $16 trillion global trade in 2016.

 China, the Philippines, Taiwan (ROC) and Vietnam claim the whole Spratly Islands while Brunei and Malaysia claim part of the Islands.
 Brunei claims the part of the South China Sea nearest to it as part of its continental shelf and exclusive economic zone (EEZ). In 1984, Brunei declared an EEZ encompassing the above-water islets it claims in Louisa Reef. Brunei does not practice military control in the area.
 Brunei's claims to the reef are based on the United Nations Convention on the Law of the Sea (UNCLOS). Brunei states that the southern part of the Spratly Islands chain is actually a part of its continental shelf, and therefore a part of its territory and resources.
 The People's Republic of China (PRC) claims are based on history and not UNCLOS. However, the PRC still claims all of the Spratly Islands as part of China. The PRC is a party to the UNCLOS, signing the agreement on 29 July 1994.
 The Republic of China (ROC), which ruled Mainland China before 1949 and has been confined to Taiwan since 1949, also claims all of the Spratly Islands.
 China claims to have discovered the islands in the Han dynasty in 2 BC. The islands were claimed to have been marked on maps compiled during the time of Eastern Han dynasty and Eastern Wu (one of the Three Kingdoms), no extant maps from any such eras exist however, thus believers are just meant to take the modern Chinese government's word that these maps did exist. Since the Yuan dynasty in the 12th century, several islands that may be the Spratlys have been labelled as Chinese territory according to the Yuanshi, an official history commissioned by the Hongwu Emperor of the Ming dynasty in 1369, which has been subject to criticism for its lack of quality and numerous errors. This labeling has also occurred in the Qing dynasty from the 13th to 19th century; the islands may have appeared on a 1755 map, among others. Archaeological surveys have found the remains of Chinese pottery and coins in the islands, cited as proof for the PRC claim, but they are more likely to have come from shipwrecks of passing Chinese junks.
 In the 19th century, Europeans found that Chinese fishermen from Hainan annually sojourned on the Spratly Islands for part of the year, while in 1877 it was the British who launched the first modern legal claims to the Spratlys.
 When the Spratlys and Paracels were being surveyed by Germany in 1883, China issued protests against them. China sent naval forces on inspection tours in 1902 and 1907 and placed flags and markers on the islands. The Qing dynasty's successor state, the Republic of China, claimed the Spratly and Paracel Islands under the jurisdiction of Hainan.
 The Spratlys and the Paracels were conquered from France by Japan in 1939. Japan administered the Spratlys via Taiwan's jurisdiction and the Paracels via Hainan's jurisdiction. The Paracels and Spratlys were handed over to Republic of China control from Japan after the 1945 surrender of Japan, since the Allied powers assigned the Republic of China to receive Japanese surrenders in that area.
 After World War II ended, the Republic of China was the "most active claimant". The Republic of China then garrisoned Itu Aba (Taiping) Island in 1946 and posted Chinese flags and markers on it along with Woody island in the Paracels, France tried, but failed to make them leave Woody island. The aim of the Republic of China was to block the French claims. The Republic of China drew up the map showing the U shaped claim on the entire South China Sea, showing the Spratly and Paracels in Chinese territory, in 1947.
 Taiwan's garrison from 1946 to 1950 and 1956–present on Itu Aba represents an "effective occupation" of the Spratly Islands.
 On May 15, 1996, the PROC submitted to the United Nations its geographic baseline, which included the Paracel Islands and Senkaku/Diaoyu Islands, but did not include the Spratly Islands.
 Taiwan garrison forces actively fended off Philippine efforts to build on the Spratly before 1971. After the UN vote to recognize the PRC, the ROC government in Taiwan no longer was in position to defend its rights. The Philippines and Vietnam took this opportunity to establish outposts in the Spratlys.
 Malaysia claims a small number of islands in the Spratly Islands and its claims cover only the islands included in its exclusive economic zone of 200 miles as defined by the United Nations Convention on the Law of the Sea. Malaysia has militarily occupied five islands that it considers to be within its continental shelf. Swallow Reef (Layang Layang / Terumbu Layang / Pulau Layang Layang) was under control in 1983 and has been turned into an island through a land reclamation which now also hosts a dive resort. The Malaysian military also occupies Ardasier Reef (Terumbu Ubi), and Mariveles Reef (Terumbu Mantanani).
 Malaysia's claims are based upon the continental shelf principle, and have clearly defined coordinates within the limits of its EEZ defined in 1979. This argument requires that the islands were res nullius and this requirement is said to be satisfied as when Japan renounced their sovereignty over the islands according to the San Francisco Treaty, there was a relinquishment of the right to the islands without any special beneficiary. Therefore, the islands became res nullius and available for annexation.
 The Republic of the Philippines claims the Spratly islands and are based on sovereignty over the Spratly Islands on the issues of res nullius and geography.
 The Philippines contend their claim was res nullius as there was no effective sovereignty over the islands until the 1930s when France and then Japan acquired the islands. When Japan renounced their sovereignty over the islands according to the San Francisco Treaty, there was a relinquishment of the right to the islands without any special beneficiary. Therefore, the islands became res nullius and available for annexation, according to the claim.
 In 1956, a private Filipino citizen, Tomás Cloma, unilaterally declared a state on 53 features in the South China Sea, calling it "Freedomland". In December 1974, Cloma was arrested and forced to sign a document to convey to the Philippines whatever rights he might have had in the territory for one peso. Cloma sold his claim to the Philippine government, which annexed (de jure) the islands in 1978, calling them Kalayaan.[citation needed]
On 11 June 1978, President Ferdinand Marcos of the Philippines issued Presidential decree No. 1596, declaring the Spratly Islands (referred to therein as the Kalayaan Island Group) as Philippine territory.
 The Philippine claim to Kalayaan on a geographical basis can be summarised using the assertion that Kalayaan is distinct from other island groups in the South China Sea, because of the size of the biggest island in the Kalayaan group.[citation needed] A second argument used by the Philippines regarding their geographical claim over the Spratlys is that all the islands claimed by the Philippines lie within its 200-mile exclusive economic zone according to the 1982 United Nations Convention on the Law of the Sea. This argument assumes that the islands were res nullius. The Republic of the Philippines also contend, under maritime law that the People's Republic of China can not extend its baseline claims to the Spratlys because the PRC is not an archipelagic state.
 On July 12, 2016, the Permanent Court of Arbitration ruled in favor of the Philippines on most of its submissions. It clarified that while it would not "rule on any question of sovereignty ... and would not delimit any maritime boundary", China's historic rights claims over maritime areas (as opposed to land masses and territorial waters) within the "nine-dash line" have no lawful effect unless entitled to under UNCLOS. China has rejected the ruling, as has Taiwan. Eight governments have called for the ruling to be respected, 35 issued generally positive statements noting the verdict but not called for compliance, and eight rejected it. The United Nations itself "doesn't have a position on the legal and procedural merits of the case or on the disputed claims", and on 12 July the Secretary-General "expressed his hope that the continued consultations on a Code of Conduct between ASEAN and China under the framework of the Declaration of the Conduct of Parties in the South China Sea will lead to increased mutual understanding among all the parties.
 
On 25 July 1994, Vietnam ratified the UNCLOS. Upon ratification it declared:  The National Assembly reiterates Viet Nam's sovereignty over the Hoang Sa and Truong Sa archipelagoes and its position to settle those disputes relating to territorial claims as well as other disputes in the Eastern Sea through peaceful negotiations in the spirit of equality, mutual respect and understanding, and with due respect of international law, particularly the 1982 United Nations Convention on the Law of the Sea, and of the sovereign rights and jurisdiction of the coastal States over their respective continental shelves and exclusive economic zones Vietnam's response to China's claim is that Chinese records on Qianli Changsha and Wanli Shitang are records about non-Chinese territories. For example, Qianli Changsha and Wanli Shitang were referred to in the ancient Chinese texts Ling Wai Dai Da and Zhu Fan Zhi as being in the Sea of Jiaozhi, Jiaozhi being the old name for a Chinese province in modern-day northern Vietnam, or as writings on foreign countries.
 Vietnam's view is that the Chinese records do not constitute the declaration and exercise of sovereignty and that China did not declare sovereignty over the Spratlys until after World War II.
 Vietnam claims the Spratlys based on international law on declaring and exercising sovereignty.
 Vietnam claims that it has occupied the Spratly and the Paracel islands at least since the 17th century, when they were not under the sovereignty of any state, and that they exercised sovereignty over the two archipelagos continuously and peacefully until they were invaded by Chinese armed forces. In Phủ biên tạp lục (撫邊雜錄, Miscellaneous Records of Pacification in the Border Area) by the scholar Lê Quý Đôn, Hoàng Sa (Paracel Islands), and Trường Sa (Spratly Islands) were defined as belonging to Quảng Ngãi District. In Đại Nam nhất thống toàn đồ (大南ー統全圖), an atlas of Vietnam completed in 1838, Trường Sa was shown as Vietnamese territory. Vietnam had conducted many geographical and resource surveys of the islands. The results of these surveys have been recorded in Vietnamese literature and history published since the 17th century. After the treaty signed with the Nguyễn dynasty, France represented Vietnam in international affairs and exercised sovereignty over the islands.
 The Cairo Declaration, drafted by the Allies and China towards the end of World War II, listed the territories that the Allies intended to strip from Japan and return to China. Despite China being among the authors of the declaration, this list did not include the Spratlys. Vietnam's response to China's claim that the Cairo Declaration somehow recognised the latter's sovereignty over the Spratlys is that it has no basis in fact.
 At the San Francisco Conference on the peace treaty with Japan, the Soviet Union proposed that the Paracels and Spratlys be recognised as belonging to China. This proposal was rejected by an overwhelming majority of the delegates. On 7 July 1951, Tran Van Huu, head of the Bảo Đại Government's (State of Vietnam) delegation to the conference declared that the Paracels and Spratlys were part of Vietnamese territory. This declaration met with no challenge from the 51 representatives at the conference.
 The text of the Treaty of San Francisco did not list the Spratlys, or any other island territories, to be returned to China.
 The Geneva Accords, which China was a signatory, settled the First Indochina War end. French Indochina was split into three countries: Laos, Cambodia and Vietnam. Vietnam was to be temporarily divided along the 17th Parallel.
 
Chapter I, Article 4 states: The provisional military demarcation line between the two final regrouping zones is extended into the territorial waters by a line perpendicular to the general line of the coast. All coastal islands north of this boundary shall be evacuated by the armed forces of the French Union, and all islands south of it shall be evacuated by the forces of the People's Army of Viet-Nam. On 26 October 1955, the Republic of Vietnam "South Vietnam" replaced the State of Vietnam (part of the French Union) and inherit of its rights. The Vietnamese government's Vietnam United Youth League, which runs the newspaper Thanh Niên News, claims that although, nothing was said explicitly about offshore archipelagos, which was of small interest by that times, it was clearly understood by all the parties that the Republic of Vietnam inherit of all the French Indochina's Vietnamese territories under the 17th Parallel. As the Paracel and the Spratly archipelagos (which lay below the 17th parallel) were part of the French Indochina since 1933, they were part of "South Vietnam" territory. The French bestowed its titles, rights, and claims over the two island chains to the Republic of Vietnam.[unreliable source?]
 The Republic of Vietnam (RVN) exercised sovereignty over the islands, by placing border markers on the Spratlys to indicate South Vietnamese sovereignty over the archipelago. Up to the end of the Vietnam War the Republic of Vietnam Navy held military control over the majority of the Spratly Islands until 1975, when North Vietnamese troops attacked South Vietnamese troops and occupied the islands. After the Vietnam War, the unified Vietnam SRV (Socialist Republic of Vietnam) continued to claim the Spratly islands as an indisputably integral part of Vietnam.
 China has produced a letter written by North Vietnam's former Prime Minister Phạm Văn Đồng in 1958 as proof that it holds sovereignty over the Paracel and Spratly islands. The Vietnamese newspaper Thanh Niên News claims China has intentionally misrepresented the letter, which contains no direct reference to either island chain. In addition, they claim that China is ignoring the spirit and time in which the letter was written. During that time, the two communist neighbors shared extremely close ties and the US navy was patrolling the Taiwan Strait, threatening them both. The letter, according to the newspaper, represented a diplomatic gesture of goodwill that has no legal relevance to the current territorial dispute.[unreliable source?]
 Thưa Đồng chí Tổng lý,

Chúng tôi xin trân trọng báo tin để Đồng chí Tổng lý rõ:

Chính phủ nước Việt Nam Dân chủ Cộng hòa ghi nhận và tán thành bản tuyên bố, ngày 4 tháng 9 năm 1958, của Chính phủ nước Cộng hoà Nhân dân Trung Hoa, quyết định về hải phận của Trung Quốc.

Chính phủ nước Việt Nam Dân chủ Cộng hòa tôn trọng quyết định ấy và sẽ chỉ thị cho các cơ quan Nhà nước có trách nhiệm triệt để tôn trọng hải phận 12 hải lý của Trung Quốc trong mọi quan hệ với nước Cộng hoà Nhân dân Trung Hoa trên mặt biển.

Chúng tôi xin kính gửi Đồng chí Tổng lý lời chào rất trân trọng.
 Dear Comrade Prime Minister,

We solemnly inform you that the Government of the Democratic Republic of Vietnam acknowledges and supports the declaration dated September 4th, 1958 by the Government of the People's Republic of China regarding the decision on the breadth of China's territorial sea.

The Government of the Democratic Republic of Vietnam respects that decision and will direct its state agencies to absolutely respect the 12-nautical mile breadth of China's territorial sea in all the relations with People's Republic of China at sea.

Respectfully yours,
 On 4 September 1958, with the seventh fleet of the US Navy patrolling the Taiwan Strait, China announced its decision to extend the breadth of its territorial waters to 12 nautical miles. The United Nations (to which China was not yet a member) had just held its first Conference on the Law of the Sea in Switzerland in 1956, and the resulting treaties, including the Convention on the Territorial Sea and the Contiguous Zone, were signed in 1958. Though the UN conference was considered a success, it left the exact breadth of each nation's territorial waters somewhat unresolved; the US, for instance, said it should extend just three nautical miles.[unreliable source?]
 On 14 September 1958, North Vietnam's PM Phạm Văn Đồng wrote his letter to PM Zhou Enlai in response to China's declaration. The Vietnamese newspaper Thanh Nien News claims that the letter has no legal relevance in China's sovereignty claims to the Paracel and Spratly archipelagos for the three following reasons:
 The islands occupied by Vietnam are organised as a district of Khánh Hòa Province. According to the 2009 census, the Trường Sa District has a population of 195 people. At the 12th National Assembly (2007–2011) Election held early in Trường Sa, the people and soldiers also voted for their local district government for the first time. For the first time, Trường Sa is organised like a normal inland district, with a township (Trường Sa) and two communes (Sinh Tồn and Song Tử Tây). Forty nine people were elected to the communes' people's councils.[citation needed] In July 2012 the National Assembly of Vietnam passed a law demarcating Vietnamese sea borders to include the Spratly and Paracel Islands.
 Champa historically had a large presence in the South China Sea. The Vietnamese broke Champa's power in an invasion of Champa in 1471, and then finally conquered the last remnants of the Cham people in a war in 1832. The Vietnamese government fears that using the evidence of Champa's historical connection to the disputed islands in the South China Sea would expose the human rights violations and killings of ethnic minorities in Vietnam such as in the 2001 and 2004 uprisings, and lead to the issue of Cham autonomy being brought to attention.
 Via UNCLOS, the United Nations provided for countries with coastlines to submit claims to the UN's Commission on the Limits of the Continental Shelf (CLCS) for their continental shelf to be extended beyond 200 nautical miles of their shores. By 13 May 2009, a total of 48 nations made full claims, and dozens more made preliminary submissions. Two of the submissions made to the CLCS addressed claims in the South China Sea (SCS) – one by Vietnam for a claim over the northern portion of the SCS (which included the Paracel Islands), and another jointly by Vietnam and Malaysia for a joint claim over a "defined area" in the middle of the SCS between the two countries, which included part of the Spratly Islands. Brunei made a preliminary submission notifying of its intention to claim a continental shelf beyond 200 nautical miles from its shores.
 China (PRC) immediately issued protests over the two submissions and called on the United Nations not to consider them. It also issued a stern warning to countries not to claim the islands which it said were its sovereign territory.
 On 23 May 2011, Former Philippine President Benigno Aquino III warned the visiting Chinese Defense Minister Liang Guanglie of a possible arms race in the region if tensions worsened over disputes in the South China Sea. In March, the Philippines complained that Chinese patrol boats had harassed a Philippine oil exploration vessel in disputed waters near the Spratlys, and subsequently filed a formal protest at the International Tribunal for the Law of the Sea (ITLOS).
 In January 2013, the Philippines formally initiated arbitration proceedings against numerous aspects of China's maritime claims and behavior in the South China Sea, which it said were "unlawful" under the United Nations Convention on the Law of the Sea (UNCLOS). An arbitration tribunal was constituted under Annex VII of UNCLOS and it was decided in July 2013 that the Permanent Court of Arbitration (PCA) would function as registry and provide administrative duties in the proceedings.
 On 12 July 2016, the arbitrators of the tribunal of PCA agreed unanimously with the Philippines. They concluded in the award that there was no evidence that China had historically exercised exclusive control over the waters or resources, hence there was "no legal basis for China to claim historic rights" over the nine-dash line. Accordingly, the PCA tribunal decision is ruled as final and non-appealable by either countries. The tribunal also criticized China's land reclamation projects and its construction of artificial islands in the Spratly Islands, saying that it had caused "severe harm to the coral reef environment". It also characterized Taiping Island and other features of the Spratly Islands as "rocks" under UNCLOS, and therefore are not entitled to a 200 nautical mile exclusive economic zone. China however rejected the ruling, calling it "ill-founded". Taiwan, which currently administers Taiping Island, the largest of the Spratly Islands, also rejected the ruling.
 On 22 July 1992, ASEAN issued a declaration on the South China Sea, emphasising that the dispute should be solved peacefully without resorting to violence.
 On 4 November 2002 in Phnom Penh, the Declaration on the Conduct of Parties in the South China Sea was signed by the 10 foreign ministers of ASEAN countries and China (PRC).  The parties explicitly undertook in this declaration, "to resolve their territorial and jurisdictional disputes by peaceful means, without resorting to the threat or use of force, through friendly consultations and negotiations by sovereign states directly concerned".
 In July 2012, China (PRC) announced that it is open to launching discussions on the Code of Conduct in the South China Sea, but called for all parties to exercise self-restraint in keeping with the spirit of previous declarations and United Nation conventions. This announcement has been criticised by many neighbouring states because of the contradictions seen in the Scarborough Shoal at that time where China has established de facto control.
 According to Filipino justice Antonio Carpio, the 1734 Velarde map showed the Spratly islands and the Scarborough shoal as part of the Philippine territory.
 In the 19th century, Europeans found that Chinese fishermen from Hainan annually sojourned on the Spratly islands for part of the year specifically for trade, which was also common for other ethnic groups in the area such as the Cham of Vietnam and the people of Palawan, Sulu, and Luzon in the Philippines. In 1877, the British launched the first modern legal claims to the Spratlys.
 When the Spratlys and Paracels were being surveyed by Germany in 1883, China issued protests against them. China sent naval forces on inspection tours in 1902 and 1907 and placed flags and markers on the islands. The Qing dynasty's successor state, the Republic of China, claimed the Spratly and Paracel islands under the jurisdiction of Hainan.
 Between April 7, 1933 and April 13, 1933, France took possession of the Spratly Islands and notification of the occupation appeared in the Official Journal of July 26, 1933, subsequently the islands was annexed to the Cochin-Chinese province of Baria on December 21, 1933 by the Cochin-China Governor J. Krautheimer.
 The Spratlys and the Paracels were conquered by Japan in 1939. Japan annexed the Spratly Islands via Taiwanese jurisdiction as part of Kaohsiung on 30 March 1939. France and UK protested and reasserted French soveregnty.
 In 1946, the Americans reminded the Philippines at its independence that the Spratlys was not Philippine territory, both to not anger Chiang Kai-shek in China and because the Spratlys were not part of the Philippines per the 1898 treaty Spain signed with America.
 The Paracels and Spratlys were handed over to Republic of China control from Japan after the 1945 surrender of Japan, since the Allied powers assigned the Republic of China to receive Japanese surrenders in that area.
 The Republic of China garrisoned Itu Aba (Taiping) island in 1946 and posted Chinese flags and markers on it along with Woody island in the Paracels, France tried, but failed to make them leave Woody island. The aim of the Republic of China was to block the French claims.
 In 1947, the Republic of China drew up the map showing the U shaped claim on the entire South China Sea, showing the Spratly and Paracels in Chinese territory. In 1947, the ROC government renamed 159 islands in the area and published the Map of the South China Sea Islands. The ROC has occupied Taiping Island, the largest island in the Spratlys, constantly since 1956.
 The Republic of China (ROC), which ruled Mainland China before 1949, has been confined to Taiwan since 1949.
 After pulling out its garrison in 1950 when the Republic of China evacuated to Taiwan, when the Filipino Tomas Cloma uprooted an ROC flag on Itu Aba laid claim to the Spratlys and, the Republic of China (now Taiwan) again regarrisoned Itu Aba in 1956.
 Taiwan's garrison from 1946 to 1950 and 1956-now on Itu Aba represents an "effective occupation" of the Spratlys. China established a coastal defence system against Japanese pirates or smugglers.
 North Vietnam recognised China's claims on the Paracels and Spratlys during the Vietnam War as it was being supported by China. Only after winning the war and conquering South Vietnam did North Vietnam retract its recognition and admitted it recognised them as part of China to receive aid from China in fighting the Americans.
 The Philippines claimed the Spratlys in 1971 under President Marcos, after Taiwanese troops attacked and shot at a Philippine fishing boat on Itu Aba.
 Under President Lee Teng-hui, Taiwan stated that "legally, historically, geographically, or in reality", all of the South China Sea and Spratly islands were Taiwan's territory and under Taiwanese sovereignty, and denounced actions undertaken there by Malaysia and the Philippines, in a statement on 13 July 1999 released by the foreign ministry of Taiwan. Taiwan and China's claims "mirror" each other; during international talks involving the Spratly islands, China and Taiwan have cooperated with each other since both have the same claims.
 Taiwan and China are largely strategically aligned on the Spratly islands issue, since they both claim exactly the same area, so Taiwan's control of Itu Aba (Taiping) island is viewed as an extension of China's claim. Taiwan and China both claim the entire island chain, while all the other claimants only claim portions of them. China has proposed co-operation with Taiwan against all the other countries claiming the islands. Taiwanese lawmakers have demanded that Taiwan fortify Itu Aba (Taiping) island with weapons to defend against the Vietnamese, and both China and Taiwanese NGOs have pressured Taiwan to expand Taiwan's military capabilities on the island, which played a role in Taiwan expanding the island's runway in 2012. China has urged Taiwan to co-operate and offered Taiwan a share in oil and gas resources while shutting out all the other rival claimants. Taiwanese lawmakers have complained about repeated Vietnamese aggression and trespassing on Taiwan's Itu Aba (Taiping), and Taiwan has started viewing Vietnam as an enemy over the Spratly Islands, not China. Taiwan's state run oil company CPC Corp's board director Chiu Yi has called Vietnam as the "greatest threat" to Taiwan. Taiwan's airstrip on Taiping has irritated Vietnam. China views Taiwan's expansion of its military and airstrip on Taiping as benefiting China's position against the other rival claimants from southeast Asian countries.
 Malaysia has militarily occupied three islands that it considers to be within its continental shelf. Swallow Reef (Layang Layang / Terumbu Layang / Pulau Layang Layang) was under control in 1983 and has been turned into an island through a land reclamation which now also hosts a dive resort. The Malaysian military also occupies Ardasier Reef (Terumbu Ubi), and Mariveles Reef (Terumbu Mantanani).
 Since 1992, Malaysia and Vietnam have agreed to jointly develop areas around these disputed islands. Malaysia has said that it is monitoring all of the actions made by countries involved in the dispute.
 Taiwan performed live fire military exercises on Taiping island in September 2012; reports said that Vietnam was explicitly named by the Taiwanese military as the "imaginary enemy" in the drill.  Vietnam protested against the exercises as violation of its territory and "voiced anger", demanding that Taiwan stop the drill. Among the inspectors of the live fire drill were Taiwanese national legislators, adding to the tensions.
 In 2010, it was reported that the former Malaysian Prime Minister Mahathir Mohamad believed Malaysia could profit from China's economic growth through co-operation with China, and said that China "was not a threat to anyone and was not worried about aggression from China", as well accusing the United States of provoking China and trying to turn China's neighbours against China. Malaysian authorities displayed no concern over China conducting a military exercise at James Shoal in March 2013, However, until present Malaysia still maintained a balance relations with the countries involved in this dispute. But since China has start encroaching its territorial waters, Malaysia has become active in condemning China.
 In 2014 Janes reported that during 2013–2014 China had begun dredging and land reclamation at three sites in the Spratlys. In contrast to the construction projections of other countries, Beijing's efforts involved reefs that for the most part were under water at high tide. Harry Harris, Pacific fleet commander of the U.S. Navy, unofficially described the project as "Great Wall of Sand" in March 2015.
 In April 2015, satellite images showed that China was constructing an airfield at Fiery Cross Reef. By September, it had completed a 3125-metre runway.
 Japanese companies applied to the French authority in Cochichina for phosphate-mining licenses in the Spratlys.
 Japan established a submarine base on Itu Aba Island.
 Vietnam published a white paper outlining its claims to the islands and disputing those of the other claimants.
 The Philippines occupied several more islands and constructed an airstrip.[where?]
 In May, two submissions were made to the UN's Commission on the Limits of the Continental Shelf (CLCS): a joint submission by Malaysia and Vietnam claims jurisdiction over their respective continental shelves out to 200 nautical miles; a submission by Vietnam claims jurisdiction over an extended shelf area. The People's Republic of China and the Philippines both protested the moves, stating that they violated agreements made with regard to the islands.
 In May, PRC patrol boats attacked and cut the cables of Vietnamese oil-exploration ships near the Spratly Islands. The incidents sparked several anti-China protests in Vietnam.
 In June, the PLA navy conducted three days of exercises, including live fire drills, in the disputed waters. This was seen as a warning to Vietnam, which had also conducted live fire drills near the Spratly Islands. PRC patrol boats fired repeated rounds at a target on an apparently uninhabited island, as twin fighter-jets streaked in tandem overhead. 14 vessels participated in the manoeuvres, staging antisubmarine and beach-landing drills aimed at "defending atolls and protecting sea lanes".
