Senegal
Senegal voted in favour of adopting the Treaty on the Prohibition of Nuclear Weapons (TPNW) at the UN negotiating conference in 2017 and has consistently voted in favour of the annual UN General Assembly resolution on the Treaty, including in 2025, when it was also one of the co-sponsors. It maintains policies and practices that are compatible with all of the prohibitions in Article 1 of the TPNW, and can therefore sign and ratify or accede to the Treaty without the need for a change in conduct.

Latest developments
Senegal attended the Third Meeting of States Parties (3MSP) to the Treaty on the Prohibition of Nuclear Weapons (TPNW) in March 2025 as an observer. It did not make a statement.
At the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) Preparatory Committee meeting in April 2025, Senegal said: ‘Nuclear disarmament is becoming increasingly a pipe dream, as nuclear-weapon States are, now more than ever, determined to preserve their nuclear arsenals, due to the unstable international environment.’ It called for action ‘to maintain the integrity of the global disarmament and non-proliferation architecture’, which includes the TPNW.1
In the First Committee of the UN General Assembly in October 2025, Senegal reaffirmed ‘the importance of determination and political will to move forward with the goal of the immediate, complete, irreversible, and verifiable elimination of nuclear weapons’. It emphasized that ‘nuclear disarmament can no longer remain a postponed promise’.2
Senegal co-sponsored the 2025 UN General Assembly resolution on the TPNW, which welcomed the Treaty’s entry into force and 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
Recommendations
