Cameroon voted in favour of a UN General Assembly resolution in 2018 that welcomed the adoption of the treaty 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”.

In 2016, Cameroon 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”.

Prior to the adoption of the treaty in 2017, nuclear weapons were the only weapons of mass destruction not subject to a comprehensive, globally applicable treaty prohibition. Cameroon supported calls in the UN General Assembly fill this “legal gap”.

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