The first part of the fifteenth session of the General Assembly met at UN Headquarters from September 20 through December 20, 1960, when it was adjourned. The second part of the session was to open on March 7, 1961. At the opening plenary meeting, Mr. Frederick R. Boland (Ireland) was elected President of the session, having obtained 46 votes out of a possible 80.

At the 876th plenary meeting, the Republics of Senegal and Mali were admitted to membership, as was the Federation of Nigeria at the 893 d meeting, thereby bringing the total membership of the UN to 99. A special report of the Security Council on the subject of the admission to membership of the Islamic Republic of Mauritania, considered by the Assembly at its 954th meeting, noted the failure of the Council to recommend Mauritania for admission; the Assembly decided to postpone indefinitely further consideration of the question. At its 895th plenary meeting, the Assembly adopted by a vote of 42 to 34, with 22 abstentions, the recomementation contained in the report of the General Committee that the Assembly reject the request of the Soviet Union for the inclusion in its agenda of the question of the representation of China in the UN, and decided not to consider at its fifteenth session any proposals to exclude the representatives of the government of the Republic of China (Nationalist) or to seat representatives of the government of the People's Republic of China (Communist). With regard to the representation in the UN of the Congo (Leopoldville), the General Assembly, at its 924th meeting, adopted by 53 votes to 24, with 19 abstentions, the draft resolution recommended by the Credentials Committee in its report; the Assembly thereby accepted the credentials issued by the head of state (President Joseph Kasavubu) and communicated by him to the President of the Assembly.
