Kam is also spoken in the single village of Đồng Mộc, Trung Sơn Commune, Yên Sơn District, Tuyên Quang Province, northern Vietnam, where there are about 35 Kam people (Edmondson &amp; Gregerson 2001). The Kam of Đồng Mộc had migrated to Vietnam from China about 150 years ago. The Kam variety spoken in Đồng Mộc is most similar to that of Lípíng Shuǐkǒu () in southeastern Guizhou, China.
