Western China is a large area. We konw whites once inhabited in Xiyu (西域, today's Xinjiang and larger than Xinjiang, not including Qingzang Plateau), but we cann't say they the first to inhabited there.  Perhaps you missed this part...from a CHINESE news site no less...     URUMQI, China (AFP) - After years of controversy and political intrigue,   archaeologists using genetic   testing  have proven that   Caucasians roamed China's Tarim Basin 1,000 years before East Asian people arrived .    China has only allowed the genetic studies in the last few years, with a 2004 study carried out by Jilin University also   finding that the mummies' DNA had Europoid genes,   further proving that the earliest settlers of Western China were not East Asians .    They were perhaps the first pot smokers too hahaha....   In 2003, a leather basket filled with cannabis leaf fragments and seeds was found next to a 2,500- to 2,800-year-old mummified shaman in the northwestern Xinjiang Uygur Autonomous Region of China.[22][23]     Lab work to identify 2,800-year-old mummy of shaman: scientists    Chinese scientists are conducting laboratory work hoping to identify a 2,800-year-old mummy presumably of a shaman in the northwestern Xinjiang Uygur Autonomous Region.     The well-preserved mummy of a seemingly  Caucasian  man with a Roman nose and deep-set eyes was unearthed from a cluster of ancient tombs in 2003 and research work has been going on ever since.      Archeologists found the mummy  most intriguing because a sack of marijuana leaves was found buried alongside the corpse.     http://integral-options.blogspot.com...-year-old.html    This mummy is from a site in the Uygur Autonomous Region.  The people who lived there, and who seem to have died out around the second century CE, were not Asian -- they were Caucasian . Little is known of these people, but the remains were fully intact and well-preserved, so there is a good chance we will learn a lot about this enigmatic people.[/I]
