The Chong (Xong) are a group estimated at 5,500 in 1984, located along the Cambodia-Thailand border at about 12° N and 103° E and in the Cardamom Mountains. The Chong are closely related to the Pear and Saoch, who also speak Mon-Khmer languages and are classified as Southwest Upland Groups. The Chong now are largely assimilated into Khmer society.
