POIPET, Cambodia: At the usually bustling border crossing of Poipet between Thailand and Cambodia, tuk-tuk driver San Noeun now has to work overnight to make ends meet.

Thailand has all but closed the land crossings in seven border provinces as a territorial dispute with Cambodia that erupted into deadly military clashes last month festers.

Cambodians living near the checkpoint in Poipet – the main land crossing between the two neighbors – say they are worried about the conflict escalating.

San Noeun, 64, said the dispute had badly impacted small businesses and people like himself who earn hand-to-mouth from daily commuters around the border.

“Since the border dispute, we cannot make much money,” he said, adding he could previously make around $18 a day.
