End Note
1

Signed on behalf of the Republic of China on 18 April 1961.  See also note 1 under "China" in the "Historical Information" section in the front matter of this volume.

In communications addressed to the Secretary-General with reference to the above-mentioned signature and/or ratification, the Permanent Representatives of the Permanent Missions to the United  of Bulgaria, the Byelorussian SSR, Mongolia, Pakistan, Poland, Romania, the Ukrainian SSR and the Union of Soviet Socialist Republics stated that their Governments considered the said signature and/or ratification as null and void, since the so-called "Government of China" had no right to speak or assume obligations on behalf of China, there being only one Chinese State, the People's Republic of China, and one Government entitled to represent it, the Government of the People's Republic of China.

In letters addressed to the Secretary-General in regard to the above-mentioned communications, the Permanent Representative of China to the United Nations stated that the Republic of China, a sovereign State and Member of the United Nations, had attended the 1961 Conference on Diplomatic Intercourse and Immunities, contributed to the formulation of the Convention concerned, signed the Convention and duly deposited the instrument of ratification thereof, and that "any statements and reservations relating to the above-mentioned Convention that are incompatible with or derogatory to the legitimate position of the Government of the Republic of China shall in no way affect the rights and obligations of the Republic of China under this Convention".

The instrument of accession deposited on behalf of the Government of China on 25 November 1975 contained the following declaration:

The "signature" on and "ratification" of this Convention by the Chiang Kai-shek clique usurping the name of China are illegal and null and void.
