On May 6 2014 in New York, the permanent representative of five nuclear powers (P5): China, France, Russia, the United States and the United Kingdom simultaneously signed Additional Protocol to the Treaty on a Nuclear-Weapon-Free Zone in Central Asia with the five Central Asian countries.

By signing the additional protocol the five nuclear powers expressed their support to the efforts of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan to establish a nuclear-weapon-free zone in Central Asia. As it was emphasized in the P5 representatives’ statements, the treaty serves the purposes of strengthening the international non-proliferation regime, advancing the nuclear disarmament process, and promoting peace and security in the region and beyond.


The Treaty entered into force on 21 March 2009 and it created the world’s first nuclear-weapon-free zone located entirely in the Northern Hemisphere. The Central Asia Nuclear Weapon Free Zone commits its signatories, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan, to refrain from developing, acquiring or possessing nuclear weapons.

The Secretary-General in his statement congratulated the five Central Asia States on their achievement of the first concrete step towards the consolidation of the zone. He expressed hope that the nuclear-weapon States ratify the Protocol without delay.

Under the protocol, the nuclear powers affirm that they also would keep these weapons out of the covered zone. The five powers previously signed similar protocols promising to respect the strictures of other nuclear weapon-free zones that cover Africa, Latin America and the Caribbean and the South Pacific.
