Open Door Policy

historical U.S. diplomacy seeking to open trade with China

The Open Door Policy was a policy between China, the United States and several nations in Europe. It opened trade with China to each of these nations. Prior to that, China was a closed country. Europe was about to fight a war to open up China by force. This grew out of the Open Door Notes sent by United States Secretary of State John Hay to diplomats in Europe.
