Laurent Sagart
Though Sino-Tibetan, Tai–Kadai, Austronesian and Austroasiatic are mostly considered to be unrelated to each other, Laurent Sagart has proposed some possible phylogenetic affinities. Specifically, Tai–Kadai and Sino-Tibetan could possibly both belong to the Sino-Austronesian language family (not to be confused with Austroasiatic) due to a scattering of cognates between their ancestral forms, and there is also some, albeit much more tenuous, evidence to suggest that Austroasiatic should also be included, however his views are but one among competing hypotheses about the phylogeny of these languages, see the Sino-Austronesian languages article for some further detail. During the 8th and 9th centuries, ethnic Koreans from Silla made overseas communities in the Wu speaking region.
