Practice Relating to Nuclear Weapons
In 1996, during a debate in the First Committee of the UN General Assembly, the representative of Colombia stated:
My country has actively participated in the process of strengthening the Treaty of Tlatelolco, a pioneering instrument in the establishment of nuclear-weapon-free zones. We will continue to support the strengthening of the regime established under that Treaty. It is gratifying to note that the number of States of the region that are parties to the Treaty today has increased to 31.
My delegation wishes to emphasize that at the Non-Aligned Movement summit last year, the Heads of State or Government encouraged the unification of the nuclear-weapon-free zones already established with those that are now being finalized. In this connection my delegation commends the initiative by Brazil with a view to the consolidation of the southern hemisphere as a nuclear-weapon-free zone.
