From 2008 to 2013, the Cambodian–Thai border dispute was an ongoing conflict, which on a number of occasions led to fighting between Cambodian and Thai forces. Sen and Thai premier Abhisit Vejjajiva negotiated a de-escalation on several occasions with the encouragement of ASEAN. Cambodia was granted sovereignty over the Preah Vihear Temple area by a UN court in 2013, ending the dispute.
