The Treaty of Tlatelolco, signed in Mexico City on 14 February 1967, created a nuclear-weapon-free zone in Latin America and the Caribbean, the first in a populated region. Promoted by Mexico after the Cuban Missile Crisis and negotiated under Alfonso García Robles, it bans the testing, possession and deployment of nuclear weapons by its parties. All 33 states of the region eventually joined it.
