In the comments to a previous entry whose thread had turned into a discussion of whether the Chinese language developed in the north (where history places it) or in the south (as its affiliation with the Tibeto-Burman languages would seem to suggest), xiaolongnu wrote:
I am going to a conference in Philly this weekend where someone is giving a paper called “Origins of Sino-Tibetan and Prehistoric Linguistic Exchanges in Eurasia.” The speaker is a Chinese scholar called Xu Wenkan, so I expect it’s pretty current Chinese scholarship on the subject. If there is sufficient interest I will report on this when I return, probably Monday or Tuesday. Or should this maybe be a new thread?
So here’s the new thread, and I eagerly await new information!
