Open Door Policy

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.
