Thais should be the last group that left Southern China as IndoChina was under the Khmer Empire up to around 1000 years ago.



Interestingly ancestors of the Khmers and the Bataks in Sumatra, could also be earlier migrants from Southern China:

From China doesn’t mean they are Chinese, Southern China was a different world 2000 years ago, hundreds of Yue tribes used to live there until Han Chinese from northern China conquered the south, most of them fled to Southeast Asia….those tribes that stayed on mixed blood with Han Chinese, which created modern Southern Chinese.
