Conference on Disarmament

The Conference on Disarmament (CD), was recognized by the Tenth Special Session on Disarmament of the United Nations General Assembly (SSOD-I) (1978) as a single multilateral disarmament negotiating forum of the international community. 

Currently, the CD primarily focuses its attention on the following issues:  

  • Cessation of the nuclear arms race and nuclear disarmament. 
  • Prevention of nuclear war, including all related matters. 
  • Prevention of an arms race in outer space. 
  • Effective international arrangements to assure non-nuclear-weapon States against the use or threat of use of nuclear weapons. 
  • New types of weapons of mass destruction and new systems of such weapons; radiological weapons. 
  • Comprehensive programme of disarmament. 
  • Transparency in armaments.

The Conference is comprised of 65 member States, including the five NPT nuclear-weapon States and 60 other States of key military significance. In addition, every year, non-member States participate, upon their request, in the CD’s work. Their number reached 50 in 2019, the highest in 20 years. 

The Director-General of the United Nations Office at Geneva, Ms. Tatiana Valovaya, is the Secretary-General of the Conference on Disarmament, who shall also act as the personal representative of the United Nations Secretary-General to the CD. Staff members of the UN Office for Disarmament Affairs Geneva Branch provide substantive and secretariat support to the CD, in close partnership with the UNOG Department of Conference Management. 


It succeeded other Geneva-based negotiating fora, which include the Ten-Nation Committee on Disarmament (1960), the Eighteen-Nation Committee on Disarmament (1962-68), and the Conference of the Committee on Disarmament (1969-78).

The CD and its predecessors have negotiated such major multilateral arms limitation and disarmament agreements such as the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on Their Destruction (BWC), the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on Their Destruction (CWC) and Comprehensive Nuclear-Test-Ban Treaty (CTBT). 


The CD meets in an annual session, which is divided into three parts of 10, 7, and 7 weeks, respectively. It adopts its ownRules of Procedure and its own agenda, taking into account the recommendations of the General Assembly and the proposals of its member States. It reports to the General Assembly annually, or more frequently, as appropriate.
