Thailand Demotes Cambodian Envoy, Expels Ambassador Amid Border Dispute

Thailand Recalls Ambassador, Expels Cambodian Envoy Amid Border Landmine Dispute

BANGKOK – Thailand has initiated a significant diplomatic escalation with Cambodia by recalling its ambassador and initiating plans to expel Cambodia’s ambassador from Bangkok. The decisive move follows a recent landmine incident that resulted in the severe injury of a Thai soldier along their contentious shared border.

The Thai Ministry of Foreign Affairs has formally protested the actions to Cambodia, asserting that the landmines discovered in the vicinity were newly placed and had not been present during prior patrols, according to a statement from the ruling Pheu Thai party. This has led to Thailand downgrading its diplomatic relations with its neighbor.

Acting Thai Prime Minister Phumtham wechayachai confirmed the downgrade and indicated that a further reassessment of diplomatic ties is underway. In a significant border control measure, the government has ordered the closure of all border checkpoints under Thai jurisdiction, effectively prohibiting tourist entry.

The incident that precipitated this diplomatic crisis occurred on Wednesday, where a Thai soldier sustained severe injuries, including the loss of a leg, due to a landmine explosion. This follows an earlier condemnation by the Thai government on Sunday, which accused Cambodia of laying anti-personnel landmines along their common frontier.

The dispute has also seen a verbal exchange between former leaders, with former Cambodian Prime minister Hun Sen publicly stating his lack of interest in communicating with former Thai Prime Minister Thaksin Shinawatra. The Thai foreign ministry previously labeled the landmines as a grave violation of international law and an infringement upon Thai sovereignty.

Foreign Ministry spokesman Nikorndej balankura detailed that inspections confirmed the landmines involved in the recent incident were freshly planted and not part of Thailand’s own ordnance. This contradicts Cambodia’s foreign ministry statement, which denied the planting of new mines and suggested that Thai soldiers had strayed from agreed patrol routes into Cambodian territory containing unexploded ordnance.

The tensions between the two nations have been simmering as a deadly exchange of fire near the Mom Bei area on May 28, which resulted in the death of a Cambodian soldier. Sence then, both countries have been engaged in a military and diplomatic standoff, marked by troop reinforcements along the border and reciprocal cross-border restrictions.

What are the potential implications of Thailand’s actions for ASEAN’s role in mediating the dispute?
