Viet Nam
29 February 1984
"The Government of the Socialist Republic of Vietnam considers that only the Government of the People's Republic of Kampuchea, which is the sole genuine and legitimate representative of the Kampuchean People, is empowered to act in their behalf to sign, ratify or accede to international conventions.
The Government of the Socialist Republic of Vietnam rejects as null and void the ratification of the above-mentioned international Convention by the so-called "Democratic Kampuchea"- a genocidal regime overthrown by the Kampuchean people since January 7, 1979.
Furthermore, the ratification of the Convention by a genocidal regime, which massacred more than 3 million Kampuchean people in gross violation of fundamental standards of morality and international laws on human rights, simply plays down the significance of the Convention and jeopardises the prestige of the United Nations."
