Nuclear-weapon-free state

Voted to adopt TPNW

has not yet signed TPNW

Argentina has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons.

Argentina 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, Argentina said that it shares “the spirit underlying the treaty” and is “analysing the impact of the treaty on other important spheres of the current regime in regards to non-proliferation and peaceful uses of nuclear energy”.

Argentina abstained from voting on 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 its opening statement to the negotiating conference, Argentina said that it “participates in this negotiation process convinced that it is an initiative that will lead to a new international standard”.

In 2016, Argentina 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”.

Argentina 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.

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