Classification

In the 1950s as part of the classification of Zhuang languages, Zuojiang Zhuang was recognised as a dialect, or language, in Guangxi, China. In 2007, ISO 639-3 also included speakers Vietnam as the Zuojiang river goes into there. The classification of Phittiyaporn (2009) suggests Zuojiang is not a single branch, but part of two main branches of the Tai language family (clades B, F, and H). See Tai languages for details.
