Southeast Asian Massif
The term Southeast Asian Massif was proposed in 1997 by anthropologist Jean Michaud to discuss the human societies inhabiting the lands above an elevation of approximately 300 metres (1,000 ft) in the southeastern portion of the Asian landmass, thus not merely in the uplands of conventional Mainland Southeast Asia. It concerns highlands overlapping parts of 10 countries: southwest China, Northeast India, eastern Bangladesh, and all the highlands of Myanmar (Burma), Thailand, Vietnam, Laos, Cambodia, Peninsular Malaysia, and Taiwan.
