This series of agreements has not yet resolved all outstanding issues. The treatment of Japanese residents by the United States continued to cause tensions between the two nations. The Alien Land Act of 1913, for example, prohibited the Japanese from owning or leasing land for more than three years and affected U.S.-Japanese relations in the years leading up to World War I. Economic competition in China, which the United States feared would lead to increased Japanese control, was another issue that exacerbated tensions between the two nations. In 1915, the Japanese launched their “twenty-one demands” to China to ask China to recognize its territorial claims, to prevent other powers from obtaining new concessions along its coasts, and to take a series of measures that should benefit the Japanese economically. China turned to the United States for help and U.S. officials responded with a statement that they would not recognize an agreement threatening the open door. Although consistent with the policy to date, this announcement has done little to benefit the Chinese. However, President Woodrow Wilson was not prepared to take a stronger position because he needed help to protect American interests in Asia, to deal with the escalating conflict in Europe and to deal with racial problems in California.
There were three essential areas of understanding in the conversation. First, Taft told Katsura that some pro-Russians in America publicly claimed that the recent war between Japan and Russia was a prelude to Japan`s aggression against the Philippines. Taft explained that Japan`s only interest in the Philippines would be to have governed these islands by a strong and friendly nation like the United States. Count Katsura firmly confirmed that this was Japan`s only interest in the Philippines, and it is already the case, Japan was not interested in the Philippines.  Second, Count Katsura stated that Japan`s policy in East and South-East Asia was to maintain general peace and that the means to achieve this was a good understanding between Japan, the United States and Great Britain.  Third, Count Katsura stated that it was the cause of the international complications that led to the war between Japan and Russia, because Korea`s autonomy led Korea to conclude agreements and agreements without care with other powers. Japan therefore felt obliged to rule out any possibility of Korean autonomy. Minister Taft said that the establishment of Japan`s sovereignty over Korea (i.e. the least powerful Korea would pay tribute or be controlled by the most powerful Japan), with the Japanese military ensuring that Korea does not enter into foreign treaties without Japan`s agreement is a logical consequence of the war and contributes to a lasting peace in the east. Taft said his views were his, but he believed President Roosevelt agreed.
 Korean historians believe that the United States recognized Japan`s sphere of influence in Korea during the discussions; In return, Japan recognized the U.S. sphere of influence in the Philippines. However, American historians who investigate official records report that no agreement has ever been reached – the two men have discussed recent events, but have not found any new policy or agreement. Both reaffirmed the well-known official policy of their own governments.
