The Treaty of Tlatelolco is the conventional name given to the Treaty for the Prohibition of Nuclear Weapons in Latin America and the Caribbean. It is embodied in the OPANAL (French: Agence pour l'interdiction des armes nucléaires en Amérique latine et dans les Caraïbes, Portuguese: Agência para a Proibição de Armas Nucleares na América Latina e no Caribe, Spanish: Organismo para la Proscripción de las Armas Nucleares en la América Latina y el Caribe, English: the Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean). Signed in 1967, it was the first treaty of its kind covering a populated area of the world, but now around 40% of the world's population live in a Nuclear-weapon-free zone.
