Laotians came from China, as Anajak Laotse! This was written in the Chinese history. Laotse we 50 millions strong, fought the Mogolians for thousand of years, until loss to the Mongolians, then migrated down to southern China, Yunnan, Chieng Toung, etc... The land of Laos & Thai now, belong to the Cambodian (Khom)! The Thais were a small tribe that lived along Anajak Laotse! But Thais & Laotians had very close relationship, almost as one! Lao & Thai migrated down southern China together, then split at the Yangsee river. However, came together as one & mixing, then fought each other. The Kha-mu that still living in Laos, are the true (Ai Lao), Lao big brother! I can go on & on, but I will stop here!👌🤘✌🤚
