Latest developments

In a closing statement to the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Mongolia and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.2

In the First Committee of the UN General Assembly in October 2022, Mongolia described the TPNW as ‘instrumental in achieving the objectives of the total elimination of nuclear weapons’ and hailed its entry into force in 2021 as ‘a milestone in the international efforts in banning these weapons’. It also welcomed the adoption by consensus of a declaration and action plan at the 1MSP, and said: ‘We are confident that these documents will enhance the implementation of the Treaty’s objective of achieving a total elimination of nuclear weapons’.3

Mongolia was one of the co-sponsors for the 2022 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.'4

Recommendations

  • Mongolia should continue to encourage other states to adhere to the TPNW.

  • Mongolia should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.

  • Mongolia should upgrade to a Modified Small Quantities Protocol with the IAEA.
