Thailand and Cambodia Clash over Military Use of Preah Vihear Temple

Thailand has presented evidence that it claims shows Cambodian forces were stationed at the Preah Vihear temple complex during recent border clashes. This assertion comes shortly after UNESCO released a detailed report confirming severe structural damage to the World Heritage site. The Thai government argues that the presence of military assets in the area violates international laws protecting cultural heritage during armed conflict.

The dispute centers on a 100-page assessment by UNESCO specialists who visited the temple in March. According to the report, every part of the monument was targeted during the fighting in July and December 2025. The assessment notes that 562 areas sustained damage from heavy shelling and shrapnel, with many architectural elements completely destroyed. UNESCO concluded that the site is under threat from serious and specific danger, calling for urgent action and multilateral negotiations to prevent further hostilities.

Allegations of Military Presence at Temple

Air Chief Marshal Praphas Sonchaidee, head of the Joint Information Center on the Thailand-Cambodia conflict, stated on Saturday that the Thai army possesses aerial images, coordinates, and photographs of weapons in the vicinity. According to reports from The Nation, these images allegedly show anti-tank rocket-propelled grenades, small arms, and anti-aircraft positions within the temple area. Sonchaidee emphasized that all parties share a responsibility to refrain from using cultural sites for military purposes.

The Thai official stated that Bangkok seeks an impartial review of the facts to ensure that heritage protection standards are applied equally. He noted that Thailand does not deny the attacks but insists that the context of potential military usage by the other side must be verified. This stance contrasts with Cambodian officials, who have accused the Royal Thai Army of deliberately targeting the structure, a claim that remains a point of contention between the two nations.

UNESCO Report Highlights Extensive Damage

The UNESCO World Heritage Centre, working with the International Council on Monuments and Sites, documented the extent of the destruction following their inspection. The report highlights that the surface of most walls is disfigured by shrapnel impacts. Furthermore, the heavy shelling may have weakened the rocky cliffs on which the temple sits, posing a risk to the structural stability of the entire complex. The specialists described the impact as profound and detrimental to the integrity of the property.

While the report clearly establishes the physical damage and the liability of parties who attack cultural properties, it does not verify the specific allegations regarding troop placement. The assessment urges for guarantees that no further acts of hostility will occur. This lack of independent verification on the ground creates a gap in the diplomatic narrative, leaving the core question of military intent unresolved despite the clear documentation of physical harm.

Diplomatic Implications and Legal Liability

The situation presents a complex legal landscape under international law. If the Thai allegations of Cambodian troop presence are substantiated, it could mitigate Thailand’s legal and moral responsibility for the damage. However, obtaining a clear answer is difficult, as both sides rely on conflicting narratives. The dispute remains entangled in broader border tensions, including frequent reports of injuries from landmines, which complicates any straightforward diplomatic resolution.

According to GN geopolitics/border, the forward question is whether multilateral negotiations can establish the guarantees demanded by UNESCO. The next steps will likely involve international scrutiny of the evidence provided by both nations. The focus will shift from documenting the damage to determining accountability, a process that may require independent verification mechanisms to break the current diplomatic deadlock.
