The Permanent Missions of Czechoslovakia and the Union of Soviet Socialist Republics further stated that the sole authorities entitled to act for China and the Chinese people in the United Nations and in international relations, and to sign, ratify, accede or denounce treaties, conventions and agreements on behalf of China, were the Government of the People's Republic of China and its duly appointed representatives.In a note addressed to the Secretary-General, the Permanent Mission of China to the United Nations stated that the Government of the Republic of China was the only legal Government which represented China and the Chinese people in international relations and that, therefore, the allegations made in the above-mentioned communica tions as to the lack of validity of the signature or ratification in question had no legal foundation whatever.6The former Yugoslavia had signed and ratified the Convention on 7 September 1956 and 20 May 1958, respectively.

The Argentine Republic rejects and considers null and void the [said declaration] of territorial extension. With reference to the above-mentioned objection, the Secretary-General received, on 28 February 1985, from the Government of the United Kingdom of Great Britain and Northern Ireland the following declaration: "The Government of the United Kingdom of Great Britain and Northern Ireland have no doubt as to their right, by notification to the Depositary under the relevant provisions of the above-mentioned Convention, to extend the application of the Convention in question to the Falkland Islands or to the Falkland Islands Dependencies, as the case may be. For this reason alone, the Government of the United Kingdom are unable to regard the Argentine [communication] under reference as having any legal effect."16See note 1 under “United Kingdom of Great Britain and Northern Ireland” in the “Historical Information” section in the front matter of this volume.
