Tensions rise on Cambodia-Thailand border: Kingdom protests against new incursions

Amid ongoing tensions at the border, Cambodia's Ministry of Foreign Affairs and International Cooperation has lodged a formal protest with Thailand, strongly condemning further Thai military incursions into Cambodian territory.

In a diplomatic note sent on 25 August 2025, Phnom Penh denounced the illegal installation of barbed wire and black netting by the Thai armed forces in the centre of the village of Chouk Chey, in Banteay Meanchey province

According to the Cambodian authorities, these repeated actions – which took place between 12 and 25 August – demonstrate a deliberate intention to extend the conflict to civilian areas, in open violation of Cambodia's sovereignty.

The Cambodian Ministry reiterates the urgent need to respect the ceasefire commitments agreed on 28 July and recorded in a 13-point memorandum of understanding dated 7 August, as well as in the 2000 memorandum. These agreements stipulate that ‘each party undertakes not to carry out provocative actions likely to exacerbate tensions,’ including military incursions into the airspace or territory of the other party.

This third act of protest, following those of 14 and 19 August, highlights the seriousness of the situation. The rapid intervention of the inhabitants of Chouk Chey, supported by local unarmed forces, made it possible to repel the Thai troops and recover the barbed wire, revealing the villagers' deep attachment to defending their land and their legitimate rights.

The ministry spokesperson described a remarkable mobilisation of citizens, motivated by the desire to protect what they consider to be their legal property, coupled with a powerful sense of patriotism.

The safety of the local population remains a priority. The Cambodian forces, faithful to the principles of the ceasefire, remained on site without weapons, ensuring the protection of civilians with professionalism and responsibility.

In this tense atmosphere, an official visit by a team of international observers representing Malaysia, Indonesia, Laos, the Philippines and Vietnam took place on 26 August. Led by Colonel Nazlee bin Abdul Rahim, this mission aims to verify and document the situation on the ground in Banteay Meanchey.

Finally, Phnom Penh points out that 18 Cambodian soldiers have now been illegally detained by Thailand for 28 days, their captivity having begun just hours after the ceasefire came into effect. This detention is a new source of tension in a fragile region, where every incident risks further poisoning bilateral relations.

According to the ministry, the international community is watching the developments in this border crisis with concern, considering it a test of respect for law and sovereignty in the Mekong region.
