“The Xia dynasty is thought to have run from the end of the third millennium B.C. to the middle of the second.”

This would indeed put the first known dynasty’s beginning well after the migration to Tibet. In which case, yes, China is playing dirty pool here. Their traditional culture, predating Communism, portrayed them as being at the center of the world, so it’s understandable to me that they felt little compunction at playing fast and loose.

Yes, I think there has always been a Chinese arrogance about being the first, best, most supreme. I'm not sure they were ever as ruthlessly revisionist about it as Mao Tse-Dong was. I think he made up anything he wanted to and backed it up with 'a bullet in the head if you don't like it.' What chaps me is that western journalists just lapped it up.

Just making it all up as you go is sounding familiar again isn't it? So far no bullets, just vague threats. A little character assassination for the recalcitrant.
