BANGKOK, June 30 (Xinhua) -- The Thailand Office of Natural Resources and Environmental Policy and Planning (ONEP) on Sunday announced that the 43rd Session of the World Heritage Committee meeting has taken into consideration three sites in Thailand, for listing as World Heritage sites.

The three sites include Si Thep Historical Park, the ensemble of Phanom Rung, Muang Tam and Plai Bat sanctuaries in Buriram province and Kaeng Krachan National Park.
