The Conference on Disarmament is the world’s principal multilateral disarmament negotiating forum. A high priority task for the CD is the negotiation of a nuclear test ban treaty. The CD is not a UN body but an autonomous body which receives support from the UN system. It was established following a recommendation of the 1978 Special Session of Disarmament of the UN General Assembly. The CD meets every year in Geneva for a three-part annual session to consider and negotiate multilateral arms control and disarmament measures. It has 37 members, representing every geographical region, and includes the five nuclear-weapon states.
