What policy did both China and Japan Implement during the 1400-1800??

China and Japan share a long history through trade, cultural exchanges, friendship, and conflict. Cross cultural contacts, before 1600 strongly influenced Japan; particularly from China with its writing system, architecture, culture, religion, philosophy, and law, many of which were introduced by the Kingdom of Baekje. Trade began in the 1860s. Many Chinese students were trained in Japan and political activists were based there before they overthrew the Chinese empire in 1912. A series of wars and confrontations took place between 1880 and 1945, with Japan seizing Taiwan, Manchuria and most of coastal China. Japan was defeated and withdrew in 1945. Since 1950 relations have been tense because of the Korean War and the Cold War. Trade has expanded greatly in the 21st century.
