 The most notable are the connections of Austronesians to the neighboring Austroasiatic, Kra-Dai, and Sinitic peoples (as Austric, Austro-Tai, and Sino-Austronesian, respectively).But they are still not widely accepted as evidence of these relationships are still tenuous and the methods used are highly contentious.In support of both the Austric and Austro-Tai hypothesis, Robert Blust connects the lower Yangtze Neolithic Austro-Tai entity with the rice-cultivating Austroasiatic cultures; assuming the center of East Asian rice domestication, and putative Austric homeland, to be located in the Yunnan/Burma border area, instead of the Yangtze River basin as is currently accepted.
