Correct answer: It served as the basis for U.S. protests against Japanese aggression in Manchuria

When Japan invaded Manchuria in 1931, the U.S. cited the Open Door Policy and the Nine-Power Treaty to condemn the violation of China’s sovereignty. The policy remained a cornerstone of U.S.-East Asian relations for decades.
