Antigua and Barbuda
Antigua and Barbuda is an example to be followed by other states, as it has adhered to all of the seven key treaties in the legal architecture on disarmament and non-proliferation of weapons of mass destruction, in addition to being party to a nuclear-weapon-free zone (NWFZ) treaty.

Latest developments
Antigua and Barbuda 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.
In the First Committee of the UN General Assembly in October 2025, the Caribbean Community (CARICOM), of which Antigua and Barbuda is a member State, reaffirmed its support for the TPNW, 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’.1
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’.2
Antigua and Barbuda 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
-
Antigua and Barbuda should continue to encourage other states to adhere to the TPNW.
-
Antigua and Barbuda should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
