Cambodian Experts Welcome ASEAN Observer Team as Key Step in Border Dispute Monitoring

PHNOM PENH, Cambodia (Sept. 11, 2025) — Cambodian political experts have welcomed the deployment of the ASEAN Interim Observer Team (IOT) to the Cambodia–Thailand border, describing it as a constructive move toward resolving the ongoing territorial dispute.

The observer team arrived in Phnom Penh on Sept. 10 and was dispatched Thursday to Preah Vihear and Banteay Meanchey provinces, where it will monitor the implementation of a ceasefire agreement over a three-month period. The deployment follows escalating tensions and recent skirmishes along the border.

The mission stems from key diplomatic milestones, including the Special Meeting on Cambodia–Thailand held July 28 in Malaysia and the Extraordinary General Border Committee Meeting convened Aug. 7 in Kuala Lumpur, which led to the formal ceasefire.

Thong Mengdevid, a lecturer at the Institute for International Studies and Public Policy at the Royal University of Phnom Penh, called the deployment “a very positive and constructive step that demonstrates ASEAN solidarity and its commitment to regional harmony through peaceful dialogue.”

“The team brings credibility and helps build trust by ensuring that the ceasefire is respected,” Mengdevid said. “While the IOT does not have enforcement power, its role in monitoring, reporting, and encouraging continued dialogue is crucial for confidence-building.”

Yang Peou, Secretary General of the Royal Academy of Cambodia, echoed the sentiment, emphasizing the importance of the Malaysia-led mission in breaking the current stalemate.

“This observer team is essential for investigating and uncovering the truth regarding the implementation of the ceasefire,” Peou said. “The IOT will reveal the reality on the ground to ASEAN and the international community—specifically, who is violating the agreement.”

Peou also praised Malaysia’s leadership as ASEAN Chair, warning that without the observer mission, Thailand could continue provoking incidents and misrepresenting facts to portray Cambodia as the aggressor.

On Thursday afternoon, Cambodia’s Ministry of National Defence facilitated the deployment of the IOT, which includes representatives from Brunei, Indonesia, Laos, Malaysia, the Philippines, Singapore, and Vietnam. The team is led by Brigadier General Dato’ Pahlawan Asri bin Shukor, Head of Mission.

The observers will be stationed at designated sites in Preah Vihear and Banteay Meanchey provinces to observe, verify, and report on developments related to the ceasefire agreement.
