Established in January 1998, the United Nations Office for Disarmament Affairs (UNODA) promotes disarmament through dialogue, confidence-building on military matters, and regional disarmament efforts. The Office for Disarmament Affairs also supports multilateral efforts aimed at achieving the ultimate goal of general and complete disarmament under strict and effective international control. UNODA actively works with other United Nations (UN) bodies such as the General Assembly First Committee and Disarmament Commission also heading various projects in Latin America and the Caribbean.

UNODA helps nations in Latin America and the Caribbean through promoting disarmament, arms control, and regional security. UNODA collaborates with governments in facilitating disarmament treaties like the Treaty for the Prohibition of Nuclear Weapons in Latin America and the Caribbean. The office facilitates collaboration among nations in the region concerning security matters. In addition, UNODA provides training, technical assistance, and advice on national policy improvement to combat the illegal trade of small arms and light weapons.
