Latest developments

Kazakhstan, which has suffered the consequences of Soviet nuclear testing, said in First Committee of the 2020 UN General Assembly that it believes that further advancing the TPNW 'is the right path forward for the international community. We should build on our past and accelerate momentum for the speedy entry into force of the Treaty and other disarmament instruments, including the Comprehensive Nuclear-Test-Ban Treaty.' See:


  • 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 refrain from all testing of nuclear-capable missiles at Sary Shagan.
