2025 Cambodian–Thai border crisis

Beginning on 28 May 2025, a crisis between Cambodia and Thailand over disputed border territory began after a brief skirmish. Parts of the border have long been disputed by both sides and the subject of prior skirmishes and tensions.

Disputes between Cambodia and Thailand over their border originates to ambiguities dating back to treaties signed between Siam (Thailand) and France. After Cambodian independence, the disputed Preah Vihear temple was awarded to Cambodia by the International Court of Justice (ICJ) in 1962, but the temple and other disputed border areas remained contested. Nationalist sentiments in both countries have fuelled tensions. Between 2008 and 2011, skirmishes between the two led to casualties on both sides before the ICJ re-affirmed its 1962 ruling.

Tensions over the border area increased in early 2025. On 13 February, Thai soldiers prevented Cambodian tourists from singing the Cambodian national anthem at the disputed Prasat Ta Muen Thom temple, creating further tension. On 28 May, Cambodian and Thai soldiers briefly exchanged fire between each other, resulting in the death of one Cambodian soldier. Both nations accused each other of instigating the skirmish.

Cambodian Prime Minister Hun Manet responded to the incident by beginning plans to seek a ruling from the ICJ, saying that he did not want to see a conflict with Thailand. Phumtham Wechayachai, Thailand's Minister of Defence, said that neither side wanted to escalate the conflict and that it had been resolved. Discussions between the Cambodian and Thai militaries were held on 29 May.
