Jakarta (ANTARA) – Two Indonesian National Armed Forces (TNI) personnel were sent to Cambodia to carry out the ASEAN Observer Team (AOT) mission, demonstrating Indonesia's commitment to maintaining stability in the Southeast Asian region.The two personnel, Lieutenant Colonel Devi Ibrohim and Major Rangga Hadi Saputra, arrived in Phnom Penh on April 25, 2026, to continue their mission to monitor the implementation of the ceasefire between Cambodia and Thailand.Upon arrival in Phnom Penh, they were received by the Charge d'Affaires of the Indonesian Embassy in Phnom Penh, Krishnajie, on April 26, 2026.”The presence of these two TNI personnel, replacing Colonel Hermawan Weharima and Lieutenant Colonel Sukmana Bayuaji, who have successfully completed their assignments, marks Indonesia's continued contribution to the regional monitoring mechanism,” the Indonesian Embassy in Phnom Penh stated in a statement on Friday.This assignment is part of Indonesia's active role in supporting ASEAN's efforts to maintain regional peace and stability.In the context of the developments of Cambodia-Thailand relations over the past year, the presence of a neutral and credible third party is considered crucial to ensure the effective implementation of the ceasefire agreement and prevent potential escalation of the conflict, the embassy added.Since joining on September 10, 2025, the Indonesian AOT team has played a role in monitoring the security situation, conducting field verification and submitting objective reports to relevant parties.This role is not only technical but also strategic in building trust and maintaining transparency between countries.The AOT is a continuation of the ASEAN Interim Observer Team (IOT), whose formation was agreed upon at a Special Meeting in Putrajaya, Malaysia, on July 28, 2025.This initiative arose from the need for a neutral and credible monitoring mechanism following the armed conflict between Cambodia and Thailand regarding the border dispute.The Terms of Reference for the AOT was then agreed upon at the Cambodia-Thailand General Border Committee (GBC) meeting on October 26, 2025, as the operational basis for carrying out tasks in the field.”For Indonesia, participation in the AOT reflects its ongoing commitment to promoting peaceful conflict resolution and strengthening the regional security architecture. The contribution of TNI personnel in the field is a concrete manifestation of Indonesia's active and constructive defense diplomacy,” the Indonesian Embassy in Phnom Penh noted.
