Participation in the Central Asian Nuclear-Weapon-Free Zone Treaty as of November 2008   Signed and ratified

The treaty was ratified by Kyrgyzstan, Uzbekistan, Turkmenistan Tajikistan and Kazakhstan, and entered into force 21 March 2009.

 

Steps towards the establishment of such a zone began with the Almaty Declaration in 1992. A resolution calling for the establishment of such a zone was adopted by consensus by the United Nations General Assembly in 1997 and reaffirmed in 2000.

Mindful of the lack of support by the nuclear powers for a similar Southeast Asian Nuclear-Weapon-Free Zone Treaty, the five permanent members of the Security Council were involved in the negotiations.

While Russia and China approved of the treaty, United States, France and United Kingdom objected to a clause which stated that the Treaty would not affect the rights and obligations of the signatories under previous international agreements because of the already existent Tashkent Treaty which involved Russia.

The United States also objected on principle to establishment of any zone disturbing "existing security arrangements to the detriment of regional and international security or otherwise abridg[ing] the inherent right of individual or collective self-defense guaranteed in the UN charter".

The United States also objected to possibility that Iran could apply to join the Treaty, so this provision was removed.

The United States, United Kingdom, and France were finally concerned about the possibility that the Treaty could forbid the transit of nuclear weapons through the territory.

In spite of attempts by United States, United Kingdom, and France to block the Treaty, it was finally signed in September 2006, although they voted against the General Assembly Resolution which welcomed the signing of the treaty in December 2006.

All five Permanent Members of the Security Council (also the five NPT nuclear weapons states) signed the Protocol to the treaty on May 6, 2014, which provides legally binding assurances not to use or threaten to use nuclear weapons against CANWFZ Treaty parties.

As of May 2016 all Permanent Members of the Security Council except the United States have ratified the protocols.
