All Central American nations have now ratified the Treaty on the Prohibition of Nuclear Weapons


With the first meeting of states parties to the Treaty on the Prohibition of Nuclear Weapons (TPNW) just one week away, Guatemala has become the 62nd country to join the landmark agreement. Its foreign minister, Mario Búcaro, deposited the country’s instrument of ratification with the UN secretary-general at an event in New York on 13 June. Accompanying him were ambassadors from other Central American countries, all of which have already ratified the TPNW.

With Guatemala’s ratification, Central America becomes the first entire region to join the TPNW. The seven Central American countries – Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama – have been vocal and consistent supporters of the treaty. During a UN working group meeting in Geneva in 2016, Guatemala proposed an important amendment to the group’s final report that strengthened a recommendation to proceed with negotiations on “a legally binding instrument to prohibit nuclear weapons” in 2017.

Guatemala hailed the TPNW’s adoption as “an important step towards a world free of nuclear weapons”, adding that “collective security can only be achieved through the prohibition and total elimination of nuclear weapons”. When the treaty opened for signature on 20 September 2017, Guatemala was among the first states to sign it. Last year it said that the TPNW’s global entry into force represented “a firm step that legally obliges the elimination of nuclear weapons”. The Guatemalan congress approved ratification of the treaty on 2 March 2022.

María Eugenia Villareal, an academic and campaigner based in Guatemala who represents the Latin American Human Security Network (SEHLAC) on ICAN’s international steering group, congratulated Guatemala and all other Central American states on this historic milestone. “I am overjoyed that Central America has become the first entire region to join the TPNW,” she said. “The states of this region are leading the way to a nuclear-weapon-free world. Bravo! Nuclear weapons are a global menace. They must be totally abolished.”
