is spoken in western Arunachal, near the border of Bhutan.
The same language, sometimes known as "Sharchopkha",
is the predominant language of the neighboring region of
southeastern Bhutan. In China the language is known as "Cangluo
Menba" or "Motuo Menba", and in Arunachal
it is often referred to as "Central Monpa" "Monpa",
however, is derived from the Tibetan word for "non-Tibetan"
and it has been used in so many ways as to risk losing clear
reference. "Tshangla" is at less risk of ambiguity
(Michailovsky 1994). "Memba", sometimes used for
a language spoken in Northernmost Arunachal, is probably
an alternate spelling of the same word.
