El Salvador

Nuclear-weapon-free state

Has signed the TPNW

Has ratified the TPNW

El Salvador has signed and ratified the Treaty on the Prohibition of Nuclear Weapons.

Hugo Martínez, the then-minister for foreign affairs of El Salvador, signed the treaty on 20 September 2017. Rubén Escalante, the then-permanent representative of El Salvador to the United Nations, deposited the country’s instrument of ratification with the UN secretary-general on 30 January 2019.

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

El Salvador 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”.

It has called “on the international community to join this effort, accelerating all internal processes to adhere to this treaty and achieve its entry into force as soon as possible”.

In 2016, El Salvador was a co-sponsor 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”.

El Salvador 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.

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