Changes

This series of agreements still did not resolve all of the outstanding issues. U.S. treatment of Japanese residents continued to cause tension between the two nations. The Alien Land Act of 1913, for example, barred Japanese from owning or leasing land for longer than three years and adversely affected U.S.-Japanese relations in the years leading up to World War I. Economic competition in China, which the United States feared would result in increasing Japanese control, was another issue that increased tensions between the two nations.

In 1915, the Japanese issued its “Twenty-One Demands” of China, in which it asked that China recognize its territorial claims, prevent other powers from obtaining new concessions along its coast, and take a series of actions designed to benefit the Japanese economically. China turned to the United States for assistance, and U.S. officials responded with a declaration that they would not recognize any agreement that threatened the Open Door. Although this was consistent with past policies, this announcement was of little use to the Chinese. However, President Woodrow Wilson was not willing to take a stronger stand given his need for assistance in protecting U.S. interests in Asia, addressing the growing conflict in Europe, and managing racial issues in California.
