On 29 April 2026, H.E. Mr. Cherdchai Chaivaivid, Ambassador and Permanent Representative of Thailand to the United Nations in New York, on behalf of the Ministry of Foreign Affairs, delivered opening remarks at the opening ceremony of the youth exhibition commemorating the 30^th anniversary of the signing of the Southeast Asia Nuclear Weapon-Free Zone Treaty (SEANWFZ), or the Bangkok Treaty, held on the margins of the 11^th Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons (11^th NPT RevCon). This project received financial support from the Government of Japan under the Youth Leader Fund for a World Without Nuclear Weapons.

The event was jointly addressed by Mrs. Josephine Moote, Chargé d’Affaires of the Permanent Mission of Kiribati, Ms. Izumi Nakamitsu, United Nations Under-Secretary-General and High Representative for Disarmament Affairs, and H.E. Mr. Do Hung Viet, Ambassador and Permanent Representative of Vietnam to the United Nations in New York, in his capacity as the President of the Review Conference. The event was also attended by Ambassadors and Permanent Representatives and members of the Permanent Missions in New York, as well as delegates participating in the Review Conference.

The exhibition builds on the commemorative activities marking the 30th anniversary of the signing of the Bangkok Treaty, held from 15–17 December 2025 in Bangkok and organized by the Ministry of Foreign Affairs in cooperation with the United Nations Regional Centre for Peace and Disarmament in Asia and the Pacific (UNRCPD). As part of the initiative, ASEAN youth were invited to submit multimedia art works under the theme “Envisioning a World Free from Nuclear Weapons,” to promote awareness and engagement among younger generations on disarmament and non-proliferation.

As the Depositary State of the Treaty of Bangkok, Thailand’s co-hosting of the youth activities and the exhibition reflects its proactive role and steadfast commitment to preserving Southeast Asia as a nuclear-weapon-free region. The initiative also underscores Thailand’s efforts to promote the relevance and significance of the Treaty through youth empowerment and public awareness-building.
