Côte d’Ivoire 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, Côte d’Ivoire 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”.

Côte d’Ivoire 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.

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