Saint Lucia

Nuclear-weapon-free state

Has signed the TPNW

Has ratified the TPNW

Saint Lucia has signed and ratified the Treaty on the Prohibition of Nuclear Weapons.

Allen Chastanet, the prime minister of Saint Lucia, signed the treaty on 27 September 2018. The country’s instrument of ratification was deposited with the UN secretary-general on 23 January 2019.

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

Saint Lucia 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 Lucia was an additional co-sponsor 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 Lucia 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 Lucia is a state party to the 1967 Treaty of Tlatelolco, which established Latin America and the Caribbean as a nuclear-weapon-free zone.
