The Marine Task Force in Trat has warned Cambodia against further provocation along the border after reports of gunfire breaches of a ceasefire agreement. On 26 March 2026, Captain Thammanoon Wanna, commander of the Trat Marine Task Force, inspected operations in Ban Tha Sen–Tmor Da and Ban Nong Ree (Ban Sam Lang), confirming repeated firing incidents last week that violated the 27 December 2025 ceasefire. He stated that Thailand would respond if such actions continue.

The commander said intelligence suggested a possible change in Cambodian field leadership had triggered the tensions, with gunfire used to try to create instability. He added that Thailand had formally notified Cambodian counterparts that any further provocation would be met with retaliation. Meanwhile, a disputed casino building in Thmor Da, previously encroached upon by Cambodia, remains under Thai control, though no order has been given to demolish it.
The wider Thmor Da area is described as a hub for scam operations controlled by Chinese-linked investors. Authorities report an increase in personnel at the site, allegedly claiming to have been sent by the Chinese embassy to protect property inside the buildings. Thai officials have requested these individuals change uniforms and carry only handguns, warning that failure to comply would constitute provocation and a breach of agreements.
According to Thai military sources, the area is not under Thai jurisdiction and contains approximately 3,000 foreign nationals, including Chinese, Vietnamese, Filipino, Bangladeshi and Pakistani workers. The operation is reportedly overseen by Chinese financiers acting as key controllers. The matter has been referred to Thailand’s Ministry of Foreign Affairs to coordinate with Chinese authorities.
Further concerns have emerged over Cambodian defensive preparations, including the construction of reinforced trenches running parallel to the Thai border. These measures are believed to reflect fears of a potential third clash, with Cambodia seeking to prevent further territorial advances by Thai forces.
Thai forces have also strengthened their own positions, installing barbed wire, earth embankments and defensive lines stretching approximately 13 kilometres. These positions are located around 900 metres from Cambodian troop deployments, as both sides maintain a tense standoff.
Amarin reported that both countries are expected to rely on the Joint Boundary Commission (JBC) mechanism to resolve the dispute. Until clearer agreements are reached, Thai troops will continue to hold their current positions under the post-ceasefire arrangement, with each side remaining in designated areas.
