Latest developments
In the First Committee of the UN General Assembly in October 2023, Timor-Leste reiterated its ‘concern on the catastrophic humanitarian impact from the use of nuclear weapons’ and welcomed the convening of the First Meeting of States Parties to the TPNW (1MSP) in 2022, which ‘was able to lay a solid foundation in complementing and strengthening the NPT’.2
Timor-Leste participated in the Second Meeting of States Parties to the TPNW (2MSP) in November and December 2023 but did not make a statement.
In accordance with Article 2 of the TPNW, Timor-Leste submitted a declaration to the UN Secretary-General on 17 March 2023 confirming that it does not own, possess or control nuclear weapons, has never done so, and does not host any other State’s nuclear weapons on its territory.3 It also took steps in 2023 towards bringing into force its Comprehensive Safeguards Agreement and Additional Protocol with the IAEA.4
Timor-Leste was one of the co-sponsors for the 2023 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’.5
