The OPANAL (Organismo para la Proscripción de las Armas Nucleares en la América Latina y el Caribe) is an international organization which promotes a non-aggression pact and nuclear disarmament in much of the Americas. In English, its name is the Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean. The agency was created as a result of the Treaty of Tlatelolco, signed in 1967 and ratified in 1969, which forbids its signatory nations from using, storing, or transporting nuclear weapons.

The first Secretary General was Leopoldo Benites of Ecuador.

The organization ensures compliance with the Treaty of Tlatelolco. It facilitates meetings between member nations, participates in other international conferences, and provides input for publications on the subject of nuclear disarmament.

OPANAL is noted as an example of the ways that middle powers can leverage soft power to address global problems, through coalition building, diplomatic pressure, and playing intermediary roles between larger powers.

History

Further information: History of the Treaty of Tlatelolco

After the Cuban Missile Crisis in October 1962, the Mexican government began pursuing denuclearization in Latin America. International conferences were held with Mexican leadership, and the drafting of the Treaty of Tletelolco in 1967 was a culmination of these efforts. OPANAL was the first international organization to achieve agreements for nuclear disarmament in a densely populated area.
