“Acting on instructions from Her Majesty’s Principal Secretary of State for Foreign and Commonwealth Affairs I hereby declare that the provisions of the Treaty shall not apply in regard to Southern Rhodesia unless and until the Government of the United Kingdom informs the other depository Governments that it is in a position to ensure that the obligations imposed by the Treaty in respect of that territory can be fully implemented.”
The Embassy of the Federal Republic of Cameroon informed the Department of State by a note dated April 24, 1969, that “The Government of the Federal Republic of Cameroon is unable to accept the reservation made by the Government of the United Kingdom . . . regarding its dependent territory of Southern Rhodesia.

By note dated June 11, 1997, the Ambassador of the United Kingdom of Great Britain and Northern Ireland informed the Secretary of State as follows:
“I am instructed by Her Britannic Majesty’s Principal Secretary of State for Foreign and Commonwealth Affairs to refer to the Treaty on the Non-proliferation of Nuclear Weapons done at London/Moscow/Washington on 1 July 1968 (hereinafter referred to as the “Treaty”) which applies to Hong Kong at present.
“I am also instructed to state that, in accordance with the Joint Declaration of the Government of the United Kingdom of Great Britain and Northern Ireland and the Government of the People’s Republic of China on the Question of Hong Kong signed on 19 December 1984, the Government of the United Kingdom will restore Hong Kong to the People’s Republic of China with effect from 1 July 1997. The Government of the United Kingdom will continue to have international responsibility for Hong Kong until that date.

“I should be grateful if the contents of this Note could be placed formally on record and brought to the attention of the other Parties to the Treaty.
