The Gambia

Nuclear-weapon-free state

Has signed the TPNW

Has ratified the TPNW


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

Adama Barrow, the president of the Gambia, signed the treaty on 20 September 2017. Mamadou Tangara, the minister for foreign affairs of the Gambia, deposited the country’s instrument of ratification with the UN secretary-general on 28 September 2018.

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

The Gambia was the first African state to ratify or accede to the treaty.

The Gambia 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, the Gambia voted in the first committee of the UN General Assembly in favour of a draft resolution that ultimately 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”.

The Gambia 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.

The Gambia is a state party to the 1996 Treaty of Pelindaba, which established Africa as a nuclear-weapon-free zone.
