Practice Relating to Nuclear Weapons
In 1996, during a debate in the First Committee of the UN General Assembly, Peru stated:
[W]e shall continue to support concerted action among the countries signatories to the treaties establishing nuclear-weapon-free zones in Latin America, Africa and Asia, with a view to inviting countries committed to that objective to accede to them, thereby extending them to new areas.
