Nuclear-weapon-free state

Has signed the TPNW

Has ratified the TPNW

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

David Granger, the president of Guyana, signed the treaty on 20 September 2017. He deposited the country’s instrument of ratification with the UN secretary-general on the same day.

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

In a statement to the United Nations in September 2019, the minister for foreign affairs of Guyana, Karen Cummings, said that the treaty “aims to transform the regional norm of the Caribbean against the possession of nuclear weapons into a global norm”.

Guyana 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 June 2019, Guyana hosted a regional forum in its capital, Georgetown, to encourage members of the Caribbean Community to sign and ratify the treaty. Delegations representing 10 states from the regional attended the forum.

They adopted a statement expressing “strong support for achieving the swift entry into force” of the treaty and agreeing “to work toward signature and ratification (as applicable) of the treaty”.

In 2016, Guyana 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”.

Guyana 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.

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