Argentina

14-11-2005

The Argentine Republic rejects the declaration made by the United Kingdom of Great Britain and Northern Ireland extending the territorial scope of the above-mentioned Convention1 to the Malvinas Islands, South Georgia and the South Sandwich Islands which are an integral part of the Argentine national territory.
It likewise rejects the British statement insofar as it refers to the intention to apply the said Convention to the so-called 'British Antarctic Territory' and affirms that that statement in no way affects the sovereign rights of the Argentine Republic over the Argentine Antarctic Sector which is an integral part of its national territory. In this connection, it is necessary to bear in mind the terms of article IV of the Antarctic Treaty, signed on 1 December 1959, to which the Argentine Republic and the United Kingdom are party.
The Argentine Republic also recalls that the Malvinas Islands, South Georgia, the South Sandwich Islands and the surrounding maritime areas are an integral part of the Argentine national territory and, since they are being illegally occupied by the United Kingdom of Great Britain and Northern Ireland, they form the subject of a sovereignty dispute between both parties, a fact acknowledged by several international bodies.
On this matter, the General Assembly of the United Nations has adopted resolutions 2065 (XX), 3160 (XXVIII), 31/49, 37/9, 38/12, 39/6, 40/21, 41/40, 42/19 and 43/25, in which it recognizes the existence of the sovereignty dispute related to the 'Question of the Malvinas Islands' and urges the Governments of the Argentine Republic and of the United Kingdom of Great Britain and Northern Ireland to resume negotiations with a view to finding a peaceful, just and lasting solution to the dispute as soon as possible. For its part, the Special Committee on Decolonization of the United Nations has repeatedly issued similar calls, most recently through the resolution adopted on 15 June 2005. The General Assembly of the Organization of American States also adopted a further declaration on the question on 7 June 2005.

China

13-01-1993

I. China has consistently stood for the complete prohibition and thorough destruction of all chemical weapons and their production facilities. The Convention constitutes the legal basis for the realization of this goal. China therefore supports the object and purpose and principles of the Convention.
II. The object and purpose and principles of the Convention should be strictly abided by. The relevant provisions on challenge inspection should not be abused to the detriment of the security interests of States Parties unrelated to chemical weapons. Otherwise, the universality of the Convention is bound to be adversely affected.
III. States Parties that have abandoned chemical weapons on the territories of other States parties should implement in earnest the relevant provisions of the Convention and undertake the obligation to destroy the abandoned chemical weapons.
IV. The Convention should effectively facilitate trade, scientific and technological exchanges and cooperation in the field of chemistry for peaceful purposes. All export controls inconsistent with the Convention should be abolished.


25-04-1997

1. China has always stood for complete prohibition and thorough destruction of chemical weapons. As CWC has laid an international legal foundation for the realization of this goal, China supports the purpose, objectives and principles of the CWC.
2. China calls upon the countries with the largest chemical weapons arsenals to ratify CWC without delay with a view to attaining its purposes and objectives at an early date.
3. The purposes, objectives and principles of CWC should be strictly observed. The provisions concerning challenge inspection shall not be abused and the national security interests of States parties not related to chemical weapons shall not be compromised. China is firmly opposed to any act of abusing the verification provisions which endangers its sovereignty and security.
4. Any country which has abandoned chemical weapons on the territory of another country should effectively implement the relevant CWC provisions, undertake the obligations to destroy those chemical weapons and ensure the earliest complete destruction of all the chemical weapons it has abandoned on another state's territory.
5. CWC should play a sound role in promoting international trade, scientific and technological exchanges and cooperation for peaceful purposes in the field of chemical industry. It should become the effective legal basis for regulating trade and exchange among the states parties in the field of chemical industry.

Cuba

29-04-1997

The Government of the Republic of Cuba declares, in conformity with article III (a) (iii) of the Convention, that there is a colonial enclave in its territory - the Guantanamo Naval Base - a part of Cuban national territory over which the Cuban State does not exercise its rightful jurisdiction, owing to its illegal occupation by the United States of America by reason of a deceitful and fraudulent Treaty.
Consequently, for the purposes of the Convention, the Government of the Republic of Cuba does not assume any responsibility with respect to the aforesaid territory, since it does not know whether or not the United States has installed, possesses, maintains or intends to possess chemical weapons in the part of Cuban territory that it illegally occupies.
The Government of the Republic of Cuba also considers that it has the right to require that the entry of any inspection group mandated by the Organization for the Prohibition of Chemical Weapons, to carry out in the territory of Guantanamo Naval Base the verification activities provided for in the Convention, should be effected through a point of entry in Cuban national territory to be determined by the Cuban Government.
The Government of the Republic of Cuba considers that, under the provisions of article XI of the Convention, the unilateral application by a State party to the Convention against another State party of any restriction which would restrict or impede trade and the development and promotion of scientific and technological knowledge in the field of chemistry for industrial, agricultural, research, medical, pharmaceutical or other purposes not prohibited under the Convention, would be incompatible with the object and purpose of the Convention.
The Government of Cuba designates the Ministry of Science, Technology and Environment, in its capacity as the national authority of the Republic of Cuba for the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on Their Destruction, as the body of the central administration of the State responsible for organizing, directing, monitoring and supervising the activities aimed at preparing the Republic of Cuba to fulfil the obligations it is assuming as a State party to the aforementioned Convention.

Holy See

12-05-1999

... the Holy See, in conformity with the nature and particular condition of Vatican City State, intends to renew its encouragement to the International Community to continue on the path towards a situation of general and complete disarmament, capable of promoting peace and cooperation at world level.
Dialogue and multilateral negotiation are essential values in this process. Through the instruments of international law, they facilitate the peaceful resolution of controversies and help better mutual understanding. In this way they promote the effective affirmation of the culture of life and peace.
While not possessing chemical weapons of any kind, the Holy See accedes to the solemn act of ratification of the Convention in order to lend its moral support to this important area of international relations which seeks to ban weapons which are particularly cruel and inhuman and aimed at producing long-term traumatic effects among the defenceless civilian population.

Iran

03-11-1997

The Islamic Republic of Iran, on the basis of the Islamic principles and beliefs, considers chemical weapons inhuman, and has consistently been on the vanguard of the international efforts to abolish these weapons and prevent their use.
1. The Islamic Consultative Assembly (the Parliament) of the Islamic Republic of Iran approved the bill presented by the Government to join the [said Convention] on 27 July 1997, and the Guardian Council found the legislation compatible with the Constitution and the Islamic Tenets on 30 July 1997, in accordance with its required Constitutional process. The Islamic Consultative Assembly decided that:
The Government is hereby authorized, at an appropriate time, to accede to the [said Convention] - as annexed to this legislation and to deposit its relevant instrument.
The Ministry of Foreign Affairs must pursue in all negotiations and within the framework of the Organization of the Convention, the full and indiscriminate implementation of the Convention, particularly in the areas of inspection and transfer of technology and chemicals for peaceful purposes. In case the afore-mentioned requirements are not materialized, upon the recommendation of the Cabinet and approval of the Supreme National Security Council, steps aimed at withdrawing from the Convention will be put in motion.
2. The Islamic Republic of Iran attaches vital significance to the full, unconditional and indiscriminate implementation of all provisions of the Convention. It reserves the right to withdraw from the Convention under the following circumstances:
-- non-compliance with the principle of equal treatment of all States Parties in implementation of all relevant provisions of the Convention;
-- disclosure of its confidential information contrary to the provisions of the Convention;
-- imposition of restrictions incompatible with the obligations under the Convention.
3. As stipulated in article XI, exclusive and non-transparent regimes impeding free international trade in chemicals and chemical technology for peaceful purposes should be disbanded. The Islamic Republic of Iran rejects any chemical export control mechanism not envisaged in the Convention.
4. The Organization for Prohibition of Chemical Weapons (OPCW) is the sole international authority to determine the compliance of States Parties regarding chemical weapons. Accusations by States Parties against other States Parties in the absence of a determination of non-compliance by OPCW will seriously undermine the Convention and its repetition may make the Convention meaningless.
5. One of the objectives of the Convention as stipulated in its preamble is to `promote free trade in chemicals as well as international cooperation and exchange of scientific and technical information in the field of chemical activities for purposes not prohibited under the Convention in order to enhance the economic and technological development of all States Parties.' This fundamental objective of the Convention should be respected and embraced by all States Parties to the Convention. Any form of undermining, either in words or in action, of this overriding objective is considered by the Islamic Republic of Iran a grave breach of the provisions of the Convention.
6. In line with the provisions of the Convention regarding non-discriminatory treatment of States Parties:
- inspection equipment should be commercially available to all States Parties without condition or limitation.
- the OPCW should maintain its international character by ensuring fair and balanced geographical distribution of the personnel of its Technical Secretariat, provision of assistance to and cooperation with States Parties, and equitable membership of States Parties in subsidiary organs of the Organization,
7. The implementation of the Convention should contribute to international peace and security and should not in any way diminish or harm national security or territorial integrity of the States Parties.

Israel

18-06-2018

The Permanent Mission of Israel to the United Nations presents its compliments to the Secretary General of the United Nations, in his capacity as depositary of the Conventio on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction, and has the honor to refer to the Palestinian request to accede to this Convention (Reference number C.N.250.2018.TREATIES-XXVI.3).
‘Palestine’ does not satisfy the criteria for statehood under international law and lacks the legal capacity to join the aforesaid Convention both under general international law and the terms of bilateral Israeli-Palestinian agreements.
The Government of Israel does not recognize ‘Palestine’ as a State, and wishes to place on record, for the sake of clarity, its position that it does not consider ‘Palestine’ a party to the Convention and regards the Palestinian request for accession as being without legal validity and without effect upon Israel’s treaty relations under the Convention.

Mauritius

09-01-2020

(…) has the honour to register its strong objection against the extension by the United Kingdom of Great Britain and Northern Ireland to the socalled ‘British Indian Ocean Territory’, of the Agreements listed at Annex and in respect of which the Secretary-General is the depositary.
The Government of the Republic of Mauritius considers that by extending these Agreements to the so-called ‘British Indian Ocean Territory’, the United Kingdom purported to exercise sovereignty over the Chagos Archipelago - a claim which is untenable under international law.
The Government of the Republic of Mauritius wishes to reiterate in emphatic terms that it does not recognize the so-called ‘British Indian Ocean Territory’. The fact that the Chagos Archipelago is, and has always been, part of the territory of the Republic of Mauritius, and that the United Kingdom has never had sovereignty over the Chagos Archipelago, has been authoritatively established by the International Court of Justice in its Advisory Opinion of 25 February 2019, on the Legal Consequences of the Separation of the Chagos Archipelago from Mauritius in 1965.
In this authoritative legal determination, the Court declared that the decolonization of the Republic of Mauritius had not been lawfully completed in 1968, since the Chagos Archipelago had been unlawfully detached in 1965, in violation of the right of self-determination of peoples and the Charter of the United Nations, as applied and interpreted in accordance with UN General Assembly resolution 1514 (XV) of 14 December 1960, resolution 2066 (XX) of 16 December 1965, resolution 2232 (XXI) of 20 December 1966 and resolution 2357 (XXII) of 19 December 1967. Accordingly, it went on to hold that the United Kingdom’s ongoing administration of the Chagos Archipelago, as the so-called ‘British Indian Ocean Territory’, was an internationally wrongful act, of a continuing nature, that engaged the State responsibility of the United Kingdom. It determined that the United Kingdom is under a legal obligation to terminate its unlawful colonial administration ‘as rapidly as possible’.
The Court further determined that all UN Member States have an obligation to cooperate with the United Nations in facilitating the completion of the decolonization of the Republic of Mauritius as rapidly as possible, including an obligation not to support the continuing wrongful conduct of the United Kingdom in maintaining its colonial administration in the Chagos Archipelago.
On 22 May 2019, the General Assembly, by an overwhelming majority of 116 votes to 6, adopted resolution 73/295. By this resolution, it endorsed the Court’s Advisory Opinion, affirmed that the Chagos Archipelago forms an integral part of the territory of the Republic of Mauritius, and demanded that the United Kingdom terminate its unlawful colonial administration within a maximum of six months, that is, by no later than 22 November 2019. That deadline has now expired.
Moreover, the General Assembly in its resolution called upon Member States to ‘cooperate with the United Nations to ensure the completion of the decolonization of Mauritius as rapidly as possible’ and to refrain from conduct that might impede or delay the completion of decolonization. It further called upon the United Nations and all its specialized agencies to recognize that the Chagos Archipelago forms an integral part of the territory of the Republic of Mauritius, to support the decolonization of the Republic of Mauritius as rapidly as possible, and to refrain from impeding that process by recognizing the so-called ‘British Indian Ocean Territory’. Lastly, the resolution also called upon ‘all other international, regional and intergovernmental organizations, including those established by treaty,’ to recognize that the Chagos Archipelago forms an integral part of the territory of the Republic of Mauritius, to support its speedy decolonization, and to ‘refrain from impeding that process’ by recognizing the so-called ‘British Indian Ocean Territory’.
The Republic of Mauritius has, over the years, consistently asserted, and hereby reasserts, its full sovereignty over the Chagos Archipelago. The Government of the Republic of Mauritius therefore unequivocally protests against the extension by the United Kingdom of the Agreements listed at Annex to the so-called ‘British Indian Ocean Territory’ and against the purported exercise by the United Kingdom of any sovereignty, rights or jurisdiction within the territory of the Republic of Mauritius.
For the above stated reasons, which arise from established principles of international law as authoritatively interpreted and applied by the International Court of Justice and endorsed by the UN General Assembly, the Government of the Republic of Mauritius does not recognize the extension by the United Kingdom of the Agreements listed at Annex to the so-called ‘British Indian Ocean Territory’, reserves all its rights in this regard, and calls upon all States Parties to the Agreements listed at Annex to reject the United Kingdom's extension of these Agreements to the so-called ‘British Indian Ocean Territory’.

Pakistan

28-10-1997

2. The objectives and purposes of the Convention must be strictly adhered to by all states. The relevant provisions on Challenge Inspections must not be abused to the detriment of the economic and security interests of the States Parties unrelated to chemical weapons. Otherwise, the universality and effectiveness of the Convention is bound to be jeopardized.
3. Abuse of the verification provisions of the Convention, for purposes unrelated to the Convention, will not be acceptable. Pakistan will never allow its sovereignty and national security to be compromised.
4. The Convention should effectively facilitate trade, scientific and technological exchanges and co-operation in the field of chemistry for peaceful purposes. All export control regimes inconsistent with the Convention must be abolished.

03-08-1994

Declaration made upon signature confirmed upon ratification.


29-12-2005

... the Kingdom of Spain considers that such an extension has been made exclusively inasmuch as Gibraltar is a territory for whose international relations the United Kingdom is responsible and, therefore, falls within the category of "any place under [the] jurisdiction or control [of a State Party]", according to the terminology used in the Convention.
Therefore, the Kingdom of Spain considers that the circulation of the United Kingdom's notification in the above-mentioned terms does not prejudge in any way either the legal status of the territory nor the sovereignty claims that the Kingdom of Spain consistently maintains with regard to Gibraltar.

Sudan

24-05-1999

In accordance with instructions received from the Government, I have the honour to refer to the communication dated 30 November 2005 from the Government of Argentina to the United Nations relating to the extension of the Convention on the Prohibition of the Development, Production, Stockpiling and use of Chemical Weapons and their Destruction, to the Falkland Islands, South Georgia and the South Sandwich Islands, and the British Antarctic Territory.
The Government of the United Kingdom of Great Britain and Northern Ireland are fully entitled to extend the Convention on the Prohibition of the Development, Production, Stockpiling and use of Chemical Weapons and on their Destruction to the Falkland Islands, South Georgia and the South Sandwich Islands, and the British Antarctic Territory.The Government of the United Kingdom of Great Britain and Northern Ireland have no doubts about the sovereignty of the United Kingdom over the Falkland Islands, South Georgia and the South Sandwich Islands, and the British Antarctic Territory, and their surrounding maritime areas, and reject the claim by the Government of Argentina to soverignty over those islands and areas and that the Falkland Islands and South Georgia and the South Sandwich Islands are under illegal occupation by the United Kingdom.

United States of America

Subject to the condition which relates to the Annex on Implementation and Verification, that no sample collected in the United States pursuant to the Convention will be transferred for analysis to any laboratory outside the territory of the United States.


18-06-2018

The United States Mission to the United Nations presents its compliments to the Executive Office of the Secretary-General of the United Nations and refers to the U.N. Secretary-General’s depositary notification C.N.250.2018.TREATIES-XXVI.3, dated May 18, 2018, regarding the purported accession of the ‘State of Palestine’ to the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction, done at Geneva September 3, 1992 (the Convention), for which the Secretary-General of the United Nations is the depositary.
The Government of the United States of America does not believe the ‘State of Palestine’ qualifies as a sovereign State and does not recognize it as such. Accession to the Convention is limited to sovereign States. Therefore, the Government of the United States of America believes that the ‘State of Palestine’ is not qualified to accede to the Convention and affirms that it will not consider itself to be in a treaty relationship with the ‘State of Palestine’ under the Convention.
