Tuvalu 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’.1

Latest developments
Tuvalu participated in the Third Meeting of States Parties (3MSP) to the Treaty on the Prohibition of Nuclear Weapons (TPNW) in March 2025 but did not make a statement.
At a high-level event on 26 September 2025 marking the International Day for the Total Elimination of Nuclear Weapons, Tuvalu called for ‘progress towards universal ratification and implementation’ of the TPNW.2
At the same event, the Pacific Islands Forum, of which Tuvalu is a member State, noted the ‘significant contribution’ of the 1985 South Pacific Nuclear Free Zone Treaty to nuclear non-proliferation and disarmament and to ‘inspiring other nuclear-weapon-free zones around the world’.3
At the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) Preparatory Committee meeting in April 2025, the States Parties to the South Pacific Nuclear Free Zone Treaty, including Tuvalu, reaffirmed their commitment to a nuclear-weapon-free world. ‘As a region devastatingly affected by nuclear testing, the slow pace of nuclear disarmament is a significant concern,’ they said.4
In the general debate of the 79th session of the UN General Assembly in September 2024, the Prime Minister of Tuvalu, Feleti Teo, noted that his country is a State Party to the TPNW and recently also acceded to the Biological Weapons Convention (BWC), ‘further solidifying our steadfast commitment to creating a world safe from nuclear and other weapons of mass destruction’.5
On 31 March 2022, Tuvalu ratified the Comprehensive Nuclear-Test-Ban Treaty (CTBT), and on 1 December 2022 it upgraded its original Small Quantities Protocol (SQP) with the International Atomic Energy Agency (IAEA) to a modified SQP.
Recommendations
-
Tuvalu should continue to encourage other states to adhere to the TPNW.
-
Tuvalu should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
-
Tuvalu should conclude and bring into force an Additional Protocol (AP) with the IAEA.
