Southeast Asia became a nuclear-weapon-free zone in 1997, after a relatively long incubation period. The idea of a SEANWFZ dates back to 1971, when the original five members (Indonesia, Malaysia, the Philippines, Singapore and Thailand) of the Association of Southeast Asian Nations (ASEAN) signed a declaration on a Zone of Peace, Freedom, and Neutrality (ZOPFAN). None of the current ASEAN member states have ever possessed nuclear weapons, and a majority of the states condemned nuclear weapons before any concrete proposals for a Southeast Asia nuclear-weapon-free zone were advanced.
The establishment of the zone served to further consolidate the commitment of the states in the region to remain nuclear-weapon-free and to work collectively towards the achievement of a world without nuclear weapons. Over the years, several of the countries in the region have engaged actively in nuclear disarmament initiatives and continue to play key roles in multilateral political endeavours on this issue. The commitment to remain nuclear-weapon-free has also manifested itself in an active role in the current realignment of the international discourse on nuclear disarmament, away from the traditional state-based security perspective towards a discourse predicated on a recognition of the catastrophic humanitarian consequences that any use of these weapons would have.
