Laurent Sagart
French linguist and Sinologist Laurent Sagart considers the Austronesian languages to be related to the Sino-Tibetan languages, and also groups the Kra–Dai languages as more closely related to the Malayo-Polynesian languages. Sagart argues for a north-south genetic relationship between Chinese and Austronesian, based on sound correspondences in the basic vocabulary and morphological parallels. Laurent Sagart (2017) concludes that the possession of the two kinds of millets in Taiwanese Austronesian languages (not just Setaria, as previously thought) places the pre-Austronesians in northeastern China, adjacent to the probable Sino-Tibetan homeland. Ko et al.'s genetic research (2014) appears to support Laurent Sagart's linguistic proposal, pointing out that the exclusively Austronesian mtDNA E-haplogroup and the largely Sino-Tibetan M9a haplogroup are twin sisters, indicative of an intimate connection between the early Austronesian and Sino-Tibetan maternal gene pools, at least. Additionally, results from Wei et al. (2017) are also in agreement with Sagart's proposal, in which their analyses show that the predominantly Austronesian Y-DNA haplogroup O3a2b*-P164(xM134) belongs to a newly defined haplogroup O3a2b2-N6 being widely distributed along the eastern coastal regions of Asia, from Korea to Vietnam. Sagart also groups the Austronesian languages in a recursive-like fashion, placing Kra-Dai as a sister branch of Malayo-Polynesian. His methodology has been found to be spurious by his peers.
