Colombia ratifies the Comprehensive Nuclear Test Ban Treaty

Earthtimes reports this morning that Colombia has ratified the Comprehensive Nuclear Test Ban Treaty (CTBT). The Preparatory Commission for the Nuclear-Test-Ban Treaty Organization (CTBTO) indicates Colombia’s date of ratification as January 29, 2008. Colombia’s ratification brings the total number of ratifications of the Treaty to 144 of 178 that have signed the CTBT.

Following a number of ratifications by smaller states this year, Colombia’s action significantly advances the CTBT toward entry into force as Colombia is one of 44 “Annex 2” states whose ratification is a prerequisite for entry into force.

CTBTO Executive Secretary Tibor Tóth remarked that:

“This is an extremely important event…Colombia's ratification creates a tipping
point and brings the Treaty one step closer to taking effect. We welcome
Colombia's move and expect other ratifications from Annex 2 countries to follow
suit.”

This bold action by Colombia demonstrates the capacity of all states to contribute to prudent, effective, and verified progress toward a world free of nuclear weapons. Ambassador Rosso Jose Serrano Cadena, Permanent Representative of the Republic of Colombia to the CTBTO said that:

Of the 44 “Annex 2” states only North Korea, India, and Pakistan have not yet signed the CTBT and China, Egypt, Indonesia, Iran, Israel, and the United States have not yet ratified.

“All peace loving countries must ratify the CTBT…We are sure that this will
happen. Also the Latin American and Caribbean region are now close to becoming a
complete CTBT continent.”

The ratification of Colombia leaves only Cuba, Dominica, Saint Vincent and the Grenadines, and Trinidad and Tobago not having signed the CTBT and Guatemala not having ratified Treaty among the states parties to the Treaty of Tlatelolco, establishing the Nuclear Weapon Free Zone in Latin America and the Caribbean.
