Tianshanbeilu culture spanned 2022–707 BCE in eastern Xinjiang. Population practiced sedentary agriculture. Culture featured abundant pottery, bronze artifacts, and jewelry. Genetic analysis shows 79.2% Eastern Eurasian maternal lineage and 20.8% Western lineage confirmed by Y-DNA. Initial settlers migrated from Hexi Corridor then mixed with western populations. Cemetery acted as cultural intermediary between Hexi Corridor and northwestern Eurasian steppes. Shared traits with Hexi, western Tianshan, and Altai cultures. Qijia culture borrowed bronze metallurgy from Tianshanbeilu and Altai via steppe route. Eastern Xinjiang hosted exchanges of cereals, animals, and painted ceramics from 3000-2500 BCE. Faience beads dated 1700-1400 BCE at Tianshanbeilu transferred technology to Western Zhou China by 1040-910 BCE. Chinese-made faience beads later exported back to Xinjiang in 1st millennium BCE. Afanasievo culture likely origin of bronze metallurgy influencing northwest China.
