They provided fresh water and fertile soil for farming. How did geography affect the movement of people, goods, and ideas in ancient East Asia? It kept trade and cultural exchange mostly among groups within China. The area provided supplies of fish, farmland, and fresh water.

East Asia is a large expanse of territory with China as its largest country. The countries of Mongolia, North and South Korea, and Japan are China’s neighbors. The island of Taiwan, off the eastern coast of China, has an independent government that has been separated from mainland China since shortly after World War II. On the southern coast of China is Hong Kong, a former British possession with one of the best ports in Asia. Under an agreement of autonomy, Hong Kong and its port were turned over to the Chinese government in 1997. Next door, to the west of Hong Kong, is the former Portuguese colony of Macau, which has also been returned to Chinese control. In western China is the autonomous region of Tibet, referred to by its Chinese name, Xizang. Tibet has been controlled by Communist China since 1949, shortly after the People’s Republic of China (PRC) was declared a country. Lobbying attempts by the Dalai Lama and others for Tibetan independence have not been successful. The region of Tibet has recently become more integrated with the country of China because of the immigration of a large number of Chinese people to the Tibetan region.
