Latest developments

Cambodia ratified the TPNW on 22 January 2021, the day that the Treaty as a whole entered into force. At the 2020 UN General Assembly's High-Level Plenary Meeting to Commemorate and Promote the International Day for the Total Elimination of Nuclear Weapons, Cambodia's Secretary of State for Foreign Affairs Ouch Borit said: 'The existence of nuclear weapons stands in direct contradiction to the objectives of the United Nations Charter, which calls on the global community to safeguard international peace and security while promoting development. Yet the existence of nuclear weapons threatens humanity and the planet as a whole. Cambodia reaffirms its commitment to global nuclear disarmament and calls on all States to come together, and through multilateral negotiation and compromise, to ensure total elimination of nuclear weapons.'

  • Cambodia should encourage other states to adhere to the TPNW.
  • Cambodia should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
