Analysts Urge UN Security Council to Halt Thai Hostilities as Border War Escalates

PHNOM PENH, Cambodia (Dec. 11, 2025) — Cambodian analysts are intensifying calls for the United Nations Security Council to convene an emergency meeting as clashes with Thailand escalate, accusing Thai forces of indiscriminate attacks on civilians, cultural sites, and frontline communities.

Analysts Warn of Escalation

Political analyst Kin Phea, director of the Royal Academy of Cambodia’s Institute of International Relations, said the violence marks a dangerous turning point.

“This is an invasion by Thai armed forces,” he said, alleging that civilian areas had been shelled. “It is more severe than previous clashes… a completely inhumane act at all levels.”

He warned that without swift UN action, the tragedy will deepen and more Cambodian civilians will die.

Geopolitical Critics Cite Breakdown of Diplomacy

Geopolitical analyst Yang Peou said diplomatic mechanisms have “collapsed,” accusing Thailand of abandoning peace initiatives, including the Kuala Lumpur Accord.

He alleged Thai forces have expanded the battlefield “hundreds of kilometres” along the border and deployed heavy weaponry, including F‑16 fighter jets.

“It is enough,” he said. “This is the time for the UN Security Council to intervene. The world cannot sit idly by while hostility destabilises the region.”

Cambodian Military Accuses Thailand of ‘War Crimes’

On Dec. 11, Defence Ministry spokesperson Lt. Gen. Maly Socheata accused Thailand of committing “war crimes,” citing the use of artillery, mortars, fighter aircraft and “toxic weapons.” She condemned the strikes as indiscriminate and in violation of international humanitarian law.

Cambodia Appeals to the United Nations

Cambodia’s Permanent Representative to the UN, Keo Chhea, submitted a formal letter to the Security Council on Dec. 10, describing the clashes as “unprovoked military aggression.”

The letter details attacks beginning Dec. 7, when Thai forces allegedly fired heavy weapons at Cambodian positions, followed by mortar fire and escalating to tanks, drones, warplanes and toxic smoke across Preah Vihear and Oddar Meanchey provinces.

Cambodia says it refrained from retaliatory fire for 24 hours “to uphold the ceasefire,” but stressed it reserves the right to self‑defense under Article 51 of the UN Charter.

The letter further accuses Thailand of suspending bilateral agreements, including a 2025 ceasefire and a 2000 border demarcation memorandum, and of relying on maps that contradict earlier treaties and international rulings.

Analysts say the combination of civilian casualties, cultural destruction, and diplomatic collapse underscores the urgency for global intervention.
