Latest developments

In a statement in the general debate of the 2021 UN General Assembly, the President of Zambia, Hakainde Hichilema, said: 'In the quest for promoting global peace and security, Zambia notes with satisfaction the entry into force of the Treaty on the Prohibition of Nuclear Weapons (TPNW), which became operative on 22 January 2021. The entry into force of the TPNW is a tangible feat towards advancing the cause of nuclear disarmament on the international stage. Zambia encourages other states that are yet to ratify the TPNW to come on board so that we can continue making advances towards achieving our aspirations towards eradicating nuclear weapons.'2

Zambia 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


  • 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.
