States Parties


Kazakhstan inherited nuclear weapons from the Soviet Union but renounced them and has since advocated for nuclear disarmament. Together with Kiribati, Kazakhstan is serving as co-facilitator on Articles 6 and 7 for the TPNW’s First Meeting of States Parties in 2022. In that role, they have produced working papers and held consultations with states, international organizations, and civil society, with the goal of generating recommendations to advance the Treaty’s implementation that would be included in the Meeting's outcome documents.

Latest developments

In a statement to the 2021 UN General Assembly's High-Level Plenary Meeting to Commemorate and Promote the International Day for the Total Elimination of Nuclear Weapons, the President of Kazakhstan, Kassym-Jomart Tokayev, welcomed the entry into force of the TPNW as a 'positive development', and noted: 'Circumstances and strategic thinking can and do change rapidly – nuclear weapons are a political choice.'1

In the First Committee of the 2021 UN General Assembly, Kazakhstan said: 'The obvious lack of progress in disarmament resulted in the recent adoption of the Treaty on the Prohibition of Nuclear Weapons, which should complement the [Non-Proliferation Treaty].'2

Kazakhstan was one of the co-sponsors of the 2021 UN General Assembly resolution on the TPNW, which called 'upon all States that have not yet done so to sign, ratify, accept, approve or accede to the Treaty at the earliest possible date'.3


  • Kazakhstan should continue to encourage other states to adhere to the TPNW.
  • Kazakhstan should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures, including by requesting that Russia continue to refrain from all testing of nuclear-capable missiles at Sary Shagan.
