TREATY CONCERNING THE PERMANENT NEUTRALITY AND OPERATION OF THE PANAMA CANAL. The United States of America and the Republic of Panama have agreed upon the following:
Article I
The Republic of Panama declares that the Canal, as an international transit waterway, shall be permanently neutral in accordance with the regime established in this Treaty. The same regime of neutrality shall apply to any other international waterway that may be built either partially or wholly in the territory of the Republic of Panama.
Article II
The Republic of Panama declares the neutrality of the Canal in order that both in time of peace and in time of war it shall remain secure and open to peaceful transit by the vessels of all nations on terms of entire equality, so that there will be no discrimination against any nation, or its citizens or subjects, concerning the conditions or charges of transit, or for any other reason, and so that the Canal, and therefore the Isthmus of Panama, shall not be the target of reprisals in any armed conflict between other nations of the world. The foregoing shall be subject to the following requirements:
(a) Payment of tolls and other charges for transit and ancillary services, provided they have been fixed in conformity with the provisions of Article III (c);
(b) Compliance with applicable rules and regulations, provided such rules and regulations are applied in conformity with the provisions of Article III;
(c) The requirement that transiting vessels commit no acts of hostility while in the Canal; and
(d) Such other conditions and restrictions as are established by this Treaty.
Article III
1. For purposes of the security, efficiency and proper maintenance of the Canal the following rules shall apply:
(a) The Canal shall be operated efficiently in accordance with conditions of transit through the Canal, and rules and regulations that shall be just, equitable and reasonable, and limited to those necessary for safe navigation and efficient, sanitary operation of the Canal;
(b) Ancillary services necessary for transit through the Canal shall be provided;
(c) Tolls and other charges for transit and ancillary services shall be just, reasonable, equitable and consistent with the principles of international law;
(d) As a pre-condition of transit, vessels may be required to establish clearly the financial responsibility and guarantees for payment of reasonable and adequate indemnification, consistent with international practice and standards, for damages resulting from acts or omissions of such vessels when passing through the Canal. In the case of vessels owned or operated by a State or for which it has acknowledged responsibility, a certification by that State that it shall observe its obligations under international law to pay for damages resulting from the act or omission of such vessels when passing through the Canal shall be deemed sufficient to establish such financial responsibility;
(e) Vessels of war and auxiliary vessels of all nations shall at all times be entitled to transit the Canal, irrespective of their internal operation, means of propulsion, origin, destination or armament, without being subjected, as a condition of transit, to inspection, search for surveillance. However, such vessels may be required to certify that they have complied with all applicable health, sanitation and quarantine regulations. In addition, such vessels shall be entitled to refuse to disclose their internal operation, origin, armament, cargo or destination. However, auxiliary vessels may be required to present written assurances, certified by an official at a high level of the government of the State requesting the exemption, that they are owned or operated by that government and in this case are being used only on government non-commercial service.
2. For the purposes of this Treaty, the terms "Canal," "vessel of war," "auxiliary vessel," "internal operation," "armament" and "inspection" shall have the meanings assigned them in Annex A to this Treaty.
Article IV
The United States of America and the Republic of Panama agree to maintain the regime of neutrality established in this Treaty, which shall be maintained in order that the Canal shall remain permanently neutral, notwithstanding the termination of any other treaties entered into by the two Contracting Parties.
Article V
After the termination of the Panama Canal Treaty, only the Republic of Panama shall operate the Canal and maintain military forces, defense sites and military installations within its national territory.
Article VI
1. In recognition of the important contributions of the United States of America and of the Republic of Panama to the construction, operation, maintenance, and protection and defense of the Canal, vessels of war and auxiliary vessels of those nations shall, notwithstanding any other provisions of this Treaty, be entitled to transit the Canal irrespective of their internal operation, means of propulsion, origin, destination, armament or cargo carried. Such vessels of war and auxiliary vessels will be entitled to transit the Canal expeditiously.
2. The United States of America, so long as it has responsibility for the operation of the Canal, may continue to provide the Republic of Colombia toll-free transit through the Canal for its troops, vessels and materials of war. Thereafter, the Republic of Panama may provide the Republic of Colombia and the Republic of Costa Rica with the right of toll-free transit.
Article VII
1. The United States of America and the Republic of Panama shall jointly sponsor a resolution in the Organization of American States opening to accession by all nations of the world the Protocol to this Treaty whereby all the signatories will adhere to the objective of this Treaty, agreeing to respect the regime of neutrality set forth herein.
2. The Organization of American States shall act as the depositary for this Treaty and related instruments.
Article VIII
This Treaty shall be subject to ratification in accordance with the constitutional procedures of the two Parties. The instruments of ratification of this Treaty shall be exchanged at Panama at the same time as the instruments of ratification of the Panama Canal Treaty, signed this date, are exchanged. This Treaty shall enter into force, simultaneously with the Panama Canal Treaty, six calendar months from the date of the exchange of the instruments of ratification.

```Under the Treaty Concerning the Permanent Neutrality and Operation of the Panama Canal (the Neutrality Treaty), Panama and the United States have the responsibility to assure that the Panama Canal will remain open and secure to ships of all nations. The correct interpretation of this principle is that each of the two countries shall, in accordance with their respective constitutional processes, defend the Canal against any threat to the regime of neutrality, and consequently shall have the right to act against any aggression or threat directed against the Canal or against the peaceful transit of vessels through the Canal.
```This does not mean, nor shall it be interpreted as, a right of intervention of the United States in the internal affairs of Panama. Any United States action will be directed at insuring that the Canal will remain open, secure, and accessible, and it shall never be directed against the territorial integrity or political independence of Panama.’’’

``In accordance with the Statement of Understanding mentioned in Article IV above: `The Neutrality Treaty provides that the vessels of war and auxiliary vessels of the United States and Panama will be entitled to transit the Canal expeditiously. This is intended, and it shall so be interpreted, to assure the transit of such vessels through the Canal as quickly as possible, without any impediment, with expedited treatment, and in case of need or emergency, to go to the head of the line of vessels in order to transit the Canal rapidly.’’’
(b) CONDITIONS:
(1) Notwithstanding the provisions of Article V or any other provision of the Treaty, if the Canal is closed, or its operations are interfered with, the United States of America and the Republic of Panama shall each independently have the right to take such steps as each deems necessary, in accordance with its constitutional processes, including the use of military force in the Republic of Panama, to reopen the Canal or restore the operations of the Canal, as the case may be.
(2) The instruments of ratification of the Treaty shall be
exchanged only upon the conclusion of a Protocol of Exchange, to be signed by authorized representatives of both Governments, which shall constitute an integral part of the Treaty documents and which shall include the following:
