Dominican Republic
The Dominican Republic 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
At the Third Meeting of States Parties (3MSP) to the Treaty on the Prohibition of Nuclear Weapons (TPNW) in March 2025, the Dominican Republic described the Treaty as ‘a valuable instrument that establishes significant limits in the nuclear field’. It also remarked that promotion of the policy of nuclear deterrence undermines disarmament and non-proliferation efforts and is incompatible with the TPNW.1
At the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) Preparatory Committee meeting in April 2025, the Dominican Republic underscored that the NPT, the TPNW, and other elements of the nuclear non-proliferation and disarmament architecture are complementary.2
At a high-level event on 26 September 2025 marking the International Day for the Total Elimination of Nuclear Weapons, the Dominican Republic reiterated its support for the TPNW, noting the Treaty’s ‘value as a clear expression of the will of the majority of [UN] member States to move towards a world that is free of nuclear weapons’.3
The Dominican Republic also recognized the importance of the TPNW in a statement to the First Committee of the UN General Assembly in October 2025.4
The Dominican Republic 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
-
The Dominican Republic should continue to encourage other states to adhere to the TPNW.
-
The Dominican Republic should ensure that all the TPNW obligations are implemented domestically, through legal, administrative, and other necessary measures.
