Latest developments

Zambia 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.'2

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Zambia delivered a statement on behalf of the African Group in the UN, which welcomed the adoption of the TPNW and stressed that it ‘does not undermine the NPT, but rather complements and strengthens the nuclear non-proliferation regime with the NPT as its foundation’.The statement also urged ‘all states to support the TPNW by signing and ratifying the Treaty at an early date’.3 In a closing statement to the NPT Review Conference, Zambia and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.4


  • Zambia should urgently ratify the TPNW.

  • Zambia should bring into force its Additional Protocol with the IAEA, and upgrade to a Modified Small Quantities Protocol.
