Southeast Asian Nuclear-Weapon-Free Zone Treaty (Treaty of Bangkok)

Opened for signature: December 15, 1995.
Entered into force: March 28, 1997.
Number of Parties: 10 full members - Brunei Darussalam, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Viet Nam.

None of the nuclear-weapon states has yet signed the Protocols, largely due to U.S. and French objections regarding the unequivocal nature of security assurances and over the definitions of territory (including exclusive economic zones).

Duration: Treaty is of a permanent nature and shall remain in force indefinitely.

Organs: Commission for the Southeast Asia Nuclear Weapon-Free Zone, Executive Committee.

Obligations: not to develop, manufacture or otherwise acquire, possess or have control over nuclear weapons; station nuclear weapons; or test or use nuclear weapons anywhere inside or outside the treaty zone; not to seek or receive any assistance in this; not to take any action to assist or encourage the manufacture or acquisition of any nuclear explosive device by any state; not to provide source or special fissionable materials or equipment to any NNWS, or any NWS unless subject to safeguards agreements with the IAEA; to prevent in the territory of states parties the stationing of any nuclear explosive device; to prevent testing of any nuclear explosive device; not to dump radioactive wastes and other radioactive matter at sea anywhere within the zone, and to prevent the dumping of radioactive wastes and other radioactive matter by anyone in the territorial sea of the states parties.

Treaty zone: the territories, continental shelves, and EEZ of the States Parties within the Zone.

Verification: by providing reports and exchanging information, and by the application of IAEA safeguards.

Visits by foreign ships and aircraft to ports and airfields, transit of airspace by foreign aircraft and navigation by foreign ships carrying nuclear weapons are left to the discretion of states parties.

The Protocol is open for signature by China, France, Russia, United Kingdom and United States. They would undertake to respect the Treaty and not to contribute to any act, which constitutes a violation of the Treaty or its Protocol by States Parties to them. They would also undertake not to use or threaten to use nuclear weapons against any State Party to the Treaty and not to use or threaten to use nuclear weapons within the Southeast Asia Nuclear Weapon-Free Zone.

SEANWFZ Commission: From 23 to 24 July 1999, the ASEAN Foreign Ministers convened the Commission of the SEANWFZ Treaty for the first time. The Commission ordered the preparation of the draft rules of procedure and initiation of all necessary actions in compliance with the Treaty, including consultations with the nuclear-weapon states, the International Atomic Energy Agency and other related bodies.

The Commission meeting was held in conjunction with the ASEAN Regional Forum (ARF) meeting in Singapore, Reportedly, at this meeting, China agreed to sign the Protocol, as did India. (Since India does not fall within the definition of an NWS as stipulated in the NPT, if the contracting parties accept an Indian signature to the Protocol they might be in technical violation of both the NPT and the Bangkok treaties.)

Background: The notion of a SEANWFZ dates back to 27 November 1971, when the original five members of ASEAN meeting in Kuala Lumpur signed a Declaration on a [ASEAN] Zone of Peace, Freedom, and Neutrality (ZOPFAN). This treaty constitutes a major step forward in achieving a Zone of Peace, Freedom and Neutrality in Southeast Asia (ZOPFAN), as elaborated in the Kuala Lumpur Declaration of November 1971.

The SEANWFZ Treaty includes two elements that go beyond other existing NWFZ agreements: (1) the zone of application also includes the continental shelves and exclusive economic zones of the contracting parties; and (2) the negative security assurance implies a commitment by the NWS not to use nuclear weapons against any state contracting or protocol party within the zone of application. In other aspects, the SEANWFZ contains all the standard obligations, prohibitions, and verification and control measures found in previous zonal treaties.

Thus far the NWS have not signed the Protocol to the SEANWFZ Treaty due to their objections over the inclusion of continental shelves and exclusive economic zones, and to the restriction not to use nuclear weapons within the zone or from within the zone against targets outside the zone.

The Bangkok Treaty does not have any designated Secretariat, given the informal style of ASEAN, but the Commission at the level of foreign ministers and the working group of Senior Officials will work to promote the full implementation of the zone.
No specific target date has been identified for the implementation of the SEANWFZ, though an ASEAN Vision 2020 adopted in December 1997 envisioned that by that year all of the NWS would have adhered to the protocol, and that the region could be free of all mass destruction weapons.
