Voted in favour of adopting TPNW
Has signed TPNW, but not yet ratified
Madagascar has signed but not yet ratified the Treaty on the Prohibition of Nuclear Weapons.
Hery Rajaonarimampianina, the then-president of Madagascar, signed the treaty on 20 September 2017.
Madagascar participated in the negotiation of the treaty at the United Nations in New York in 2017 and voted in favour of its adoption.
Madagascar 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, Madagascar 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”.
Madagascar 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.
Madagascar is a state party to the 1996 Treaty of Pelindaba, which established Africa as a nuclear-weapon-free zone.
