Abstract
This thesis deals with the parts played by the United States and Japan during the Allied intervention in Siberia. In presenting this material, it was thought necessary to discuss the different interpretations of the Lansing-Ishii Agreement to serve as a background to show that the Siberian intervention was one more step in Japan’s policy to extend her political and economic influence over Asia and one more attempt of the United States to prevent this aggression. |The outline of the thesis is as follows: First, a summary of both the Japanese and American interpretations of the Lansing-Ishii Agreement. This is followed by a study of the Japanese American diplomacy which led to intervention, - a study which shows the reluctance of the United States Government to intervene and its final decision to do so in order to check Japanese ambitions in Siberia. The third chapter briefly discusses the period of intervention showing the constant friction between the United States and Japan. The fourth' chapter deals with our quick withdrawal and Japan’s prolonged occupation.
