And in 1905, U.S. Secretary of War William Howard Taft met with Prime Minister Katsura Taro in Japan. The Anglo-Japanese Treaty of 1902 had raised some concerns in the United States. Under the 1902 agreement between Britain and Japan, if the United States and Japan come into conflict, Britain could be forced to join Japan against the United States. They concluded the secret Taft-Katsura Agreement, by which the United States recognized Japanese rule over Korea and approved the Anglo-Japanese alliance of 1902. At the same time, Japan recognized U.S. control over the Philippines. This set of agreements has still not resolved all the outstanding issues. The treatment of Japanese residents by the United States continued to lead to tensions between the two nations. The Alien Land Act of 1913, for example, prohibited Japanese from owning or leasing land for more than three years and affected U.S.-Japan relations in the years leading up to World War I.
Economic competition in China, which the U.S. feared would lead to increasing Japanese control, has been another topic that has heightened tensions between the two nations. In 1915, the Japanese published their "twenty-one claims" against China, asking China to recognize its territorial claims, prevent other powers from obtaining new concessions along its coasts, and take a series of measures that should benefit the Japanese economically. China has asked the U.S. for help, and U.S. officials responded with a statement that they would not recognize a deal that threatened the open door. While this is in line with the policy pursued so far, this announcement has hardly benefited the Chinese. However, President Woodrow Wilson was unwilling to take a stronger stance, as he needs help to protect U.S. interests in Asia, to deal with the growing conflict in Europe, and to deal with racial issues in California. After occupying Korea to fight Russia, Japan left its troops there. Japan ignored Korean objections, replaced the Korean military, and abolished the Korean Ministry of Post and Communications. He allowed for several years the appearance of self-management in Korea, but remained the true master [the Japanese conquest of government functions, the forced abdication of the Korean emperor, and the intrusion into all aspects of Korean society culminated in July 1907 with an agreement that placed Korea entirely under Japanese control].
The agreement appeared to be a sign of a cordial relationship between the two emerging powers. But there were those who saw him as a "quarrel horse" who had to measure Japanese receptivity to American interests in Asia. Critics attacked President Roosevelt, who had sacrificed Chinese interests in Manchuria and Korea in favor of improving relations with Japan. Others feared that the agreement would not contain any measures to guarantee China`s independence and territorial integrity. Over time, the conflicts of objectives between the United States and Japan in the Pacific led to a war between the two countries. ROOT TAKAHIRA AGREEMENT, an agreement reached on November 30, 1908 by U.S. Secretary of State Elihu Root and Japanese Ambassador Baron Kogoro Takahira. He said that both governments wanted to expand their trade in the Pacific; its intention to uphold the open door policy and China`s independence and integrity; His determination to respect the territorial possessions of the other in the Pacific; and their willingness to communicate with each other when these principles are threatened.. . .
