北碧府
In Kanchanaburi Province, many Gong have intermarried with Karen and Mon people. Sisawat and Sangkhlaburi have since been flooded by the construction of a dam, and the speakers have been dispersed to other places. As of 1991 in Kanchanaburi Province, Gong has not been spoken for 20-30 years, with most Gong people speaking Thai or Karen instead.
