Thailand shortened operating hours at 10 border crossings with Cambodia, citing security concerns, as tensions between the two countries simmered after a deadly clash last month.

Cambodian soldiers agreed to retreat from the Thai border in Ubon Ratchathani province after a talk between regional forces of both countries on Sunday.

Thailand’s armed forces are ready to defend the border in the face of a deadly clash with Cambodia that erupted last week, a top official said, adding that the country wants to maintain peace with its neighbor.
