Kháng language
Kháng (), also known as Mang U’, is an Austroasiatic language of Vietnam. It is closely related to the Bumang language of southern Yunnan, China. Classification
Paul Sidwell (2014) classifies Khang as Palaungic, although Jerold Edmondson (2010) suggests it is Khmuic. Kháng is most closely related to Bumang (Edmondson 2010). Distribution
Kháng speakers are an officially recognized ethnic group in Vietnam, and officially numbered 10,272 in 1999. The Kháng are distributed in the following districts of northwest Vietnam in Sơn La Province and Lai Châu Province:
