Thai Army reports Si Sa Ket border trench issue resolved with Cambodia
Liaison teams from both sides resolved the Hill 450 issue through talks after trenches and barbed wire raised concerns about Thai sovereignty.
- Cambodian troops dug trenches and installed barbed wire in the Si Sa Ket border area, in a potential encroachment on Thai territory.
- The Thai Army announced the issue was resolved smoothly through negotiations between liaison teams from both countries.
- As part of the agreement, the Cambodian side will restore the area to its original condition by filling in the trenches and removing the obstacles.
- A Thai Army spokesperson confirmed the resolution and urged the public to rely on official information rather than social media speculation.
Cambodian troops dug trenches and installed barbed wire at Hill 450 in the Chong Sa-ngam area of Phu Sing district, Si Sa Ket province, in actions that may have encroached on Thailand’s sovereign territory.
At the Royal Thai Armed Forces Headquarters on Thursday (September 17, 2026), Maj Gen Winthai Suvaree, spokesperson for the Royal Thai Army, said liaison teams representing both sides in the area had held talks.
The Cambodian side had agreed to restore the area to its original condition, and the matter had been resolved smoothly through negotiations.
Winthai urged people in the area who might be anxious or preparing for a possible escalation to rely on official information.
He noted that social media information came from various sources and could cause public concern.
Local administrative and military officials were continuously exchanging information, he added, and the situation was not as concerning as some information and opinions appearing on social media suggested.
Winthai said there had been no official report from units in the area explaining why Cambodian troops dug the trenches in this case.
Given that the border extends for more than 500 kilometres and small units are stationed along it, incidents can sometimes arise, particularly during periods when deployment lines remain unchanged.
These may include verbal confrontations, organised activities or inappropriate conduct.
The Thai side had to be particularly vigilant over changes to the terrain, trench-digging and the installation of obstacles.
Although the Thai side was closely monitoring the area, he acknowledged that incidents of this kind could still occur.
He added that co-operation had been forthcoming in every case once discussions and negotiations were held.
According to Winthai, further details from units in the area were needed before determining whether the Cambodian side’s agreement to fill in the trenches and remove the obstacles amounted to an acknowledgement that the actions had encroached on Thai sovereignty.
Units deployed there already knew the deployment lines, while the obstacles may simply have been viewed as measures to protect a unit.
However, an objection was necessary because the two sides were operating in close proximity.
He maintained that the issue was not a cause for concern because liaison teams from both sides had been able to resolve it.
