A brief Open Door Policy definition: The Open Door Policy was a trade agreement between the United States, China, Japan, and several European countries. US Secretary of State John Hay created the Open Door Policy in 1899/1900 in order to allow the US, Japan, and select European countries equal trade access to China, a country that previously had no trade agreements. The Open Door Policy lasted nearly 50 years, until the communist party’s 1949 victory in China’s civil war.
