Has signed the TPNW
Has ratified the TPNW
Uruguay has signed and ratified the Treaty on the Prohibition of Nuclear Weapons.
Elbio Rosselli, the then-permanent representative of Uruguay to the United Nations, signed the treaty when it opened for signature on 20 September 2017. He deposited the country’s instrument of ratification with the UN secretary-general on 25 July 2018.
In an address to the United Nations following the signing ceremony in September 2017, the minister for foreign affairs of Uruguay, Rodolfo Nin Novoa, called on “all countries to sign this instrument, which aims to ensure a decent life for future generations and avoid a humanitarian catastrophe”.
Uruguay participated in the negotiation of the treaty at the United Nations in New York in 2017 and voted in favour of its adoption.
Uruguay 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 a statement to the United Nations in September 2019, Uruguay urged “all states who have not yet done so to accede and ratify”.
In 2016, Uruguay 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”.
Uruguay 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.
Uruguay is a state party to the 1967 Treaty of Tlatelolco, which established Latin America and the Caribbean as a nuclear-weapon-free zone.
