Peru ratified the Treaty on the Prohibition of Nuclear Weapons (TPNW) on 23 December 2021, becoming the 59th state party. The ministry of foreign affairs said that the move highlights Peru’s “high commitment to its obligations under international human rights and humanitarian law”, as well as its “commitment to promoting international peace and security”.
Addressing the UN General Assembly this September, the minister of foreign affairs of Peru, Óscar Maúrtua, hailed the TPNW’s entry into force as a “great achievement” and “a legal and moral starting point on a long road to achieve nuclear disarmament”.
Peru is the 14th country in Latin America to ratify the TPNW, following Mexico, Cuba, Venezuela, Costa Rica, Nicaragua, Uruguay, El Salvador, Panama, Bolivia, Ecuador, Paraguay, Honduras, and Chile. An additional four countries in the region have signed but not yet ratified the treaty: Brazil, Colombia, the Dominican Republic, and Guatemala.
