You have posted many articles about the Urumchi mummies and related discoveries that emphasize that the Silk Route grew up along an East - West melding of cultures. The Aryians moved into India from northern Persia as well. A lot more to learn about the lands along the Route.
I can also recall some speculation that China’s remarkable bronze culture came from along the Silk Road which would make the copper smelting at this site more important. Finally, the introduction of the horse and chariot warriors from Central Asia comes to mind from the time periods represented in these ruins.
