About Us


In order to ensure compliance with the obligations of the Treaty of Tlatelolco, the Contracting Parties established in 1969 the Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean (OPANAL).

The Agency is responsible for holding meetings among Member States related to the purposes, provisions and procedures established by the Treaty.

The Treaty of Tlatelolco establishes the General Conference, the Council and the Secretariat as principal organs of OPANAL. The Secretary-General is the highest officer of the Secretariat.

OPANAL may establish subsidiary bodies as the General Conference may deem necessary, such as the Committee on Contributions and Administrative and Budgetary Matters (CCAAP).

By provision of Article 7 of the Treaty of Tlatelolco, OPANAL headquarters is located in Mexico City.

OPANAL is the only regional organization in the world entirely dedicated to achieving nuclear disarmament and non-proliferation.
