Similarities between Sumer trade economics and China trade economics

By the time of the Uruk period (4100–2900 BC), the volume of trade goods transported along the canals and rivers of southern Mesopotamia facilitated the rise of many large, stratified, temple-centered cities (with populations of over 10,000 people) where centralized administrations employed specialized workers.

China’s main point of transportation for their trade was their rivers and canals, which also strengthened their economy and kept them on a steady rise.
