Saint Kitts & Nevis

Nuclear-weapon free state

Participated in TPNW negotiations

Has signed TPNW, but not yet ratified

Saint Kitts and Nevis has signed but not yet ratified the Treaty on the Prohibition of Nuclear Weapons.

Mark Brantley, minister for foreign affairs of Saint Kitts and Nevis, signed the treaty at a high-level ceremony on 26 September 2019. 

Saint Kitts and Nevis participated in the negotiation of the treaty at the United Nations in New York in 2017 and voted in favour of its adoption.

Saint Kitts and Nevis has promoted universal adherence to the treaty, including by co-sponsoring a UN General Assembly resolution in 2019 that calls upon all states to sign, ratify, or accede to the treaty “at the earliest possible date”.

In 2016, Saint Kitts and Nevis voted in favour of the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

Saint Kitts and Nevis was among 127 states that endorsed a “humanitarian pledge” in 2015–16 to cooperate “in efforts to stigmatise, prohibit, and eliminate nuclear weapons”. The pledge was instrumental in building momentum and support for convening the negotiations.

Saint Kitts and Nevis is a state party to the 1967 Treaty of Tlatelolco, which established Latin America and the Caribbean as a nuclear-weapon-free zone.
