Same races, different names: The Ethnic Groups of Greater Indo-China

The Greater Indo-China region which also incorporates the NE states of India, Myanmar and eastern Bangladesh is full of numerous ethnic groups little-known to the rest of the world.  Many of the tribes and ethnic groups there have related ethnic cousins across international borders.  In different countries, some of these tribes are known as different names.  I have just found out some of these:
Marma of Bangladesh = Rakhine of Myanmar
Zo (generic name) = Mizo of Mizoram, India = Kuki of Manipur & Nagaland, India = Baum of Bangladesh = Chin of Myanmar
Rohingya of Myanmar = (subset of ) Chittagonian of Bangladesh
Kachin of Myanmar = Jingpo of China
