The Cambodian government has deployed military forces and advanced weaponry acquired from China to the country’s northern frontier amid growing tensions with Thailand.
Prime Minister Hun Manet has issued a stark warning: if Thai troops are not withdrawn from contested border zones, Cambodia will respond with force. He further stated that if a conflict erupts between the two nations, its consequences could ripple across Southeast Asia, from the third to potentially the fifth geopolitical region.
His father, former Prime Minister Hun Sen, has urged a return to the status quo, calling for the dispute to be resolved peacefully. Observers on the ground report an apparent increase in Thai troop presence along the border, while Cambodian forces have reportedly withdrawn and dismantled some positions.
When a Cambodian citizen serving at the front lines publicly questioned the military’s decision to retreat, Hun Sen accused him of treason and called on Thailand to extradite him back to Cambodia. These developments have raised pressing questions. Is this merely a rift between political allies or something more? Are Cambodian military strategies being executed with foresight, or is the planning reactionary?
In an effort to take the dispute to an international level, Prime Minister Hun Manet has initiated legal proceedings against the Thai government, citing historical treaties signed between France and Siam. However, under previous administrations led by the Cambodian People’s Party and guided by Hun Sen, several bilateral agreements were signed with Thailand concerning land and maritime boundaries. It remains unclear whether those agreements invoked or replaced any historical treaties previously in force.
Among the Cambodian public, there is growing concern and confusion. Many are unaware of whether any of the agreements signed under Hun Sen’s leadership explicitly referenced historic treaties or if they are now being interpreted as having been violated by Thailand.
Recent reports from Thai media outlets including Bangkok Post, Thai News, Khao Sod and international agency AFP suggest that tensions may be more complex than previously understood. According to a senior Thai military commander from the Second Army Region, speaking on Saturday, June 7, Cambodia allegedly breached the terms of the 2000 Memorandum of Understanding, known as MoU43. The Thai side reportedly filed over 400 complaints but received little cooperation in return.
On February 8, 2025, clashes broke out near the An Ses or Chong An Ma crossing along the border between Cambodia’s Preah Vihear province and Thailand’s Ubon Ratchathani. Thai authorities claimed that Cambodian soldiers had set fire to the Vimean Treimuk meeting hall, a trilateral facility built jointly by Cambodia, Thailand and Laos nearly three decades ago. The structure has served as a venue for border coordination meetings and a resting point for pilgrims visiting a nearby Buddhist statue.
According to a prior agreement signed by all three nations, military forces were required to maintain a 500-metre buffer zone from the building. Thai officials now accuse Cambodian troops of moving 150 metres into Thai territory. As for the fire that consumed the hall, Thai commanders say investigations are ongoing and no conclusions have yet been drawn.
Independent observers remain cautious. No party has been officially blamed, and evidence remains inconclusive. In the words of an old Khmer proverb, “A man who has often lied, even when he tells the truth once, is not believed.” For many Cambodians, the path forward lies not in reaction but in reason, to avoid further embarrassment on the international stage.
