Rise and fall of Austroasiatic race
The Austroasiatic languages, formerly known as Mon–Khmer, are a large language family of Mainland Southeast Asia, also scattered throughout India, Bangladesh, Nepal and the southern border of China, with around 117 million speakers. The name Austroasiatic comes from the Latin words for "South" and "Asia", hence "South Asia". Of these languages, only Vietnamese, Khmer, and Mon have a long-established recorded history, and only Vietnamese and Khmer have official status as modern national languages. In Myanmar, the Wa language is the de facto official language of Wa State. The rest of the languages are spoken by minority groups and have no official status.
