China, Timor-Leste Expected to Join Southeast Asia Nuclear-Free Treaty

China has committed to signing the Southeast Asia Nuclear Weapon-Free Zone (SEANWFZ) Treaty without reservation once all documentation is ready, marking a significant step for regional security. The treaty, in force since 1997, aims to prevent the use or movement of nuclear weapons in Southeast Asia, including countries’ exclusive economic zones and continental shelves, with ASEAN urging all nuclear powers, including the U.S., Russia, Britain, France, and China, to sign it. Alongside China, Russia has agreed to sign, while the United States is still reviewing the treaty. Additionally, Timor-Leste is set to become a full ASEAN member and accede to the SEANWFZ Treaty by the 47th ASEAN Summit in October, thus expanding the nuclear-free zone's geographical scope. ASEAN leaders emphasize the treaty as a cornerstone of regional security architecture and highlight ongoing cooperation with the International Atomic Energy Agency to promote the peaceful use of nuclear technology. These developments reflect ASEAN's commitment to global disarmament efforts amid a complex security landscape and aim to strengthen multilateral relations in the region.
