The correct answer is B) would allow all nations to trade with China on equal terms.
The United States “open door policy” would allow all nations to trade with China on equal terms.
The Open Door policy was created by the United States to protect the equity of countries on trade with China. It was the main foreign policy in East Asia. In 1889, the policy generated an international protocol for all the countries that traded with China. The countries that participated in the policy were Italy, Germany, Japan, France, Russia, and Great Britain. When Japan was defeated in WWII and Communism entered China in 1949, signified the end of the Open Door policy.
