On 16 July 2025, near Chong Bok, Ubon Ratchathani Province, three soldiers from Thailand’s Infantry Company 6021, while conducting a routine patrol along an established route within Thai territory, stepped on a landmine. The Royal Thai Government has since received reports from the responsible security agencies that after their subsequent investigations, the evidence collected confirm that the landmines were a type of anti-personnel mine not employed or stockpiled by the Kingdom of Thailand and were also recently laid. Assessments and related evidence discovered by the responsible security agencies point to the conclusion that the laying of these mines were a blatant violation of international law.

The Royal Thai Government condemns in the strongest terms the use of anti-personnel mines. Such an act is a clear violation of the sovereignty and territorial integrity of the Kingdom of Thailand, which is an outright breach of the principles that are fundamental to international law and enshrined in the United Nations Charter, as well as a clear violation of the obligations under the Anti – Personnel Mine Ban Convention. Thailand, as a State Party, will take action in accordance with the said Convention, while continuing to resolve our differences with Cambodia through existing bilateral channels. Thailand calls on Cambodia to cooperate on humanitarian demining efforts along the border of the two countries as bilaterally agreed by both Prime Ministers
