The visit included on-site observation, verification and reporting on the border situation and the implementation of stabilization measures outlined in prior joint statements.
The Royal Government of Cambodia and the Ministry of National Defence reaffirmed their commitment to fully implement the Joint Statement of the Third Special Meeting of the Cambodia–Thai General Border Committee dated 27 December 2025 and the Joint Declaration on the Peace Agreement dated 26 October 2025. The ministry stated that it continues to support the ASEAN Observer Team’s mandate and has welcomed friendly countries offering assistance for observation activities.
Institutional Role
The Cambodian Liaison Group (CLG) served as the local facilitator for the ASEAN Observer Team (AOT), arranging access and coordination for observation activities at the O’Smach checkpoint. The AOT’s stated function during the visit was to verify compliance with ceasefire-related stabilization measures and to prepare an independent report on the border situation.
Key Developments
- Timing and place: The verification activity took place on 23 May 2026 at O’Smach International Border Checkpoint, Oddar Meanchey Province.
- Leadership: The mission was led by the AOT Head of Mission (AOT HOM) from the Philippines and coordinated on site by Cambodia’s CLG.
- Mandate reference: The Ministry referenced implementation commitments under the 27 December 2025 GBC joint statement and the 26 October 2025 Cambodia–Thailand joint declaration.
Operational Implications
Verification and observation by an ASEAN team provide a documented mechanism for monitoring adherence to agreed border stabilization measures and for informing subsequent reporting to regional stakeholders. Cambodian authorities framed the activity as part of efforts to restore normalcy, peace, stability and security for communities living along the Cambodia–Thailand border.
