All of Southeast Asia was occupied, relatively recently, (~6000 years ago) by populations that were genetically close to the Andamanese and to the funny admixture fraction in Brazilian Amerindians. Closer than anyone else, anyhow.

I’m sorry. I guess I didn’t yet read that ancient DNA paper on Southeast Asia.
Here it is. “We find that early genomes from Hoabinhian hunter-gatherer contexts in Laos and Malaysia have genetic affinities with the Onge hunter-gatherers from the Andaman Islands, while Southeast Asian Neolithic farmers have a distinct East Asian genomic ancestry related to present-day Austroasiatic-speaking populations. We also identify two further migratory events, consistent with the expansion of speakers of Austronesian languages into Island Southeast Asia ca. 4 kya, and the expansion by East Asians into northern Vietnam ca. 2 kya.”
