The Conference of the Committee on Disarmament was a United Nations disarmament committee authorized by a General Assembly resolution. It began work in 1969 as the successor to the Eighteen Nation Committee on Disarmament.
The Conference of the Committee on Disarmament (CCD) succeeded the Eighteen Nation Committee Disarmament (ENCD) as the U.N.'s disarmament committee in 1969. In addition to the name change General Assembly Resolution 2602(XXIV) expanded the membership from the ENDC's 18 to the new CCD's 26. The CCD was enlarged again by the General Assembly from 26 to 31 nations in 1975. Throughout the process of UN disarmament negotiations, including through its various name changes, the CCD received instructions from and reported to the UN General Assembly. The CCD, like its two predecessors was chaired by the United States and Soviet Union.
The CCD included the original members of the Ten Nation Committee on Disarmament (TNCD) as well as the eight additional member nations of the ENCD. The ENCD actually only included the participation of seventeen nations, as France did not participate in an official capacity. However, they were involved in an unofficial role in consultations with the other Western representatives. While France was an original member of the ENCD, it again chose not to participate in the negotiations or sessions of the CCD.
Original members of TNCD: (Western Bloc) - Canada, France, Great Britain, Italy, United States. (Eastern Bloc) - Bulgaria, Czechoslovakia, Poland, Romania, Soviet Union.
Nations added to ENCD: Brazil, Burma, Ethiopia, India, Mexico, Nigeria, Sweden, United Arab Republic (UAR).
