From about 10,000 B.C.E. agriculture was practiced in China. It apparently originated independently of somewhat earlier developments in Egypt and Mesopotamia but was perhaps influenced by developments in Southeast Asia, where rice was also cultivated very early. By 5000 B.C.E. there were Neolithic village settlements in several regions of China. The primary Neolithic crops were drought-resistant millet, grown in the loess soils of the north, and rice, grown in the wetlands of the lower reaches of the Yangzi River. In both areas pigs, dogs, and cattle were domesticated, and by 3000 B.C.E. sheep had become important in the north and water buffalo in the south. Silk production can also be traced back to this period.

Over the course of the fifth to third millennia B.C.E., many distinct regional Neolithic cultures emerged. These Neolithic societies left no written records, but we know from the material record that over time they came to share more social and cultural practices. Many practices related to the treatment of the dead spread to other groups from their original area. Fortified walls made of rammed earth were built around settlements in many places, suggesting not only increased contact between Neolithic societies but also increased conflict.
