Excerpt from change request document:

Kucong speakers are classified under the Lahu nationality in China but are, in most cases, separated from the primary Lahu population by significant distances and are often reported on distinctly in Chinese sources (cf. YJDZ 1983). Ethnologue 15 confuses Kucong with Lahu Shi, but Kucong speakers are not particularly affiliated with Lahu Shi (Yellow Lahu) any more than they are with Lahu Na (Black Lahu). Speakers applied for distinct nationality status in the early 1980’s, but, instead, were classified under the Lahu nationality in 1989. Speakers in Vietnam belong to the Cosung Nationality. Bradley (2002:104) notes that Kucong is not mutually intelligible with Lahu.
