Thailand and Cambodian forces will return to their previously agreed positions, Thai Defence Minister Phumtham Wechayachai said, following talks on Sunday, after both reinforced their military presence in response to 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.

Cambodia’s government says it plans to seek a ruling from the U.N.’s International Court of Justice over violent border disputes with Thailand.
