Is any member of the Sinitic family native outside the borders of China / Taiwan / Hong Kong / Macau?
I know Chinese is related to some quite different languages like Tibetan and Burmese, the latter of which is native outside the territories which might be thought of as "Chinese language territories". ...
All the Sino-Tibetan languages I can think of are isolating. Are there any with a fusional or agglutinative morphology? If so, can you show some examples?
