Latest developments

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Nigeria expressed full support for the TPNW: ‘Rather than undermine the NPT, the nuclear ban treaty offers a strong and complementary process in furtherance of the disarmament pathways of the NPT.’2 In a closing statement to the NPT Review Conference, Nigeria and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.3

Marking the International Day for the Total Elimination of Nuclear Weapons on 26 September 2022, Nigeria noted its role as a member of the ‘core group’ of states that promoted the negotiation of the TPNW and reiterated its support for the declaration and action plan adopted at the 1MSP.4

In the First Committee of the UN General Assembly in October 2022, Nigeria urged ‘all members of the international community, especially nuclear-weapon states and those under the so-called “nuclear umbrella”, to seize the opportunity to sign and ratify the Treaty at an early date and to pursue the goal of a nuclear-weapon-free world.’5

Nigeria 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.'6


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

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