Thailand Downgrades Ties with Cambodia After Border Mine Blast
Thailand has downgraded its diplomatic relations with Cambodia and recalled its ambassador following a landmine explosion that seriously injured a Thai soldier along the contested border on July 23, 2025. The incident marks the latest in a series of confrontations between the two countries and comes amid growing tensions along their shared frontier.
The explosion occurred at approximately 4:55 p.m. in the Chong An Ma area of Nam Yuen District, Ubon Ratchathani Province. According to military officials, five soldiers were injured, including Sergeant Phichitchai Boonkorat, who lost his right leg. Four others were treated for symptoms including chest tightness and hearing issues due to the blast’s concussion.
In response, the Thai government ordered the immediate closure of two ancient temples in the disputed area and shut four key border checkpoints: Chong Chom, Chong Sai Taku, Chong An Ma, and Chong Sa-ngam. The Ministry of Foreign Affairs also filed a formal diplomatic protest, asserting that the mines were newly planted and had not been present in previous patrols.
The current situation mirrors a similar incident on July 16 in the Chong Bok area, also in Ubon Ratchathani, where a landmine blast injured three Thai soldiers, one of whom lost a leg. Thai authorities claim both incidents involved recent mine placements, and military attachés from 47 countries were briefed on the findings, which Thailand says confirm the mines were newly installed.
In a strong move, Acting Prime Minister Phumtham Wechayachai, who also serves as Interior Minister, ordered the downgrading of diplomatic relations, recalling the Thai ambassador from Phnom Penh and sending Cambodia’s ambassador in Bangkok back. He noted the government is reviewing the situation and may reassess the relationship further depending on developments.
The Royal Thai Army condemned the placement of landmines as a violation of sovereignty and a breach of international law, referencing the UN Charter and the Anti-Personnel Mine Ban Convention.
As the situation escalates, Army Commander General Pana Klaewplodtook has directed both the 1st and 2nd Army Areas to implement the “Chakraphong Phuwanat” war contingency plan to manage the ongoing border crisis. Senior military leaders are scheduled to inspect the site of the latest incident on July 24.
Those expected to visit the area include General Pana, Lieutenant General Chaipruek Duangpraphat (Deputy Army Chief), Lieutenant General Boonsin Padklang (2nd Army Area Commander), and Major General Theeranant Nantkhwang (Commander of the Military Intelligence Unit).
