OAS Secretary General Welcomes the 45th Anniversary of the Signing of the Tlatelolco Treaty

  February 14, 2012

The Secretary General of the Organization of American States (OAS), José Miguel Insulza, welcomed today the 45th anniversary of the Treaty of Tlatelolco, extending his congratulations to the signers of the agreement that consolidated Latin America and the Caribbean as the first Nuclear-Weapons-Free Zone in the world.

“With great satisfaction we commemorate this visionary initiative that represents a monumental step towards the promotion of peace and international security, and further constitutes a sound demonstration of the region’s commitment with the cause of disarmament and nonproliferation,” he said.

The Treaty of Tlatelolco and the the Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean (OPANAL) have become an exemplary reference point for the creation of other Nuclear-Weapons-Free Zones (NWFZ) in the world. “We hope that with this celebration the parties will reaffirm their commitment to promoting a world free of nuclear arms,” he added.

Today 33 States are part of the NWFZ of Latin America and the Caribbean, and a total of 114 States are part of the five NWFZ in the world. On the interest of these, Secretary General Insulza asserted that “to increase the capacities of these groups, it is necessary to work in coordination to promote spaces for dialogue, expand the Free Zones and reach other objectives such as the elimination of the role of nuclear weapons in policies on security, the complete prohibition of nuclear tests, and the promotion of educational programs for peace and disarmament.”

He also noted that “more than four decades after the signing of the Treaty, the conditions of the current geopolitical order are very different. Nevertheless, the unconditional development of a process of disarmament and total and verifiable nonproliferation continues to be a fundamental axis for achieving lasting peace and security.”

Finally, Insulza reiterated “the commitment of the OAS with the regimen of disarmament and nonproliferation founded in Tlatelolco, advocating for its continual vigilance and expansion, and asserting our irrefutable right to live in peace and free from any threat posed by nuclear arms.”
