Latest developments
In the First Committee of the UN General Assembly in October 2025, Trinidad and Tobago urged States to use the review conferences for the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and the Treaty on the Prohibition of Nuclear Weapons (TPNW) in 2026 ‘to demonstrate concrete progress toward disarmament and to reinforce our collective responsibility for a world free of nuclear weapons’.2
The Caribbean Community (CARICOM), of which Trinidad and Tobago is a member State, also addressed the First Committee, reaffirming its support for the TPNW and emphasizing that the First Review Conference in 2026 offers a ‘crucial opportunity to strengthen norms against these weapons and to accelerate the momentum toward their elimination’.3
In a separate statement to the Committee, CARICOM hailed the TPNW as ‘a landmark achievement that reinforces and complements the international legal framework for nuclear disarmament’ and ‘embodies the collective moral, legal, and humanitarian imperative to eliminate these weapons once and for all’. It urged all States that have not yet joined the Treaty to do so ‘without delay’.4
Trinidad and Tobago 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’.5
Recommendations
-
Trinidad and Tobago should continue to encourage other states to adhere to the TPNW.
-
Trinidad and Tobago should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
-
Trinidad and Tobago should conclude and bring into force an Additional Protocol (AP) with the International Atomic Energy Agency (IAEA), and upgrade to a modified Small Quantities Protocol (SQP).
