Yes, the Shang Dynasty people in Southern China people may well have been Negritos or maybe Melanesian types. That is well known.
The Australoid -> Mongoloid transition seems to have been later in Southern China and Vietnam than it was in the north, where it occurred much earlier, around 9,000 YBP.
In the South, the Australoid -> Mongoloid transition took place 2,300-4,500 YBP, and many Southeast Asians have not even fully transitioned but are still transitional types moving from Australoids towards Neomongoloids, that is, they are Paleomongoloids. There are figures on the Angkor Watt temples that look very much like Negrito or Melanesian people. These may well have been the basic Khmer type ~3,000-4,000 YBP.
