Changes in Japanese strategy in 1939–1940 and the internationalization of the Sino–Japanese War

Abstract

In the early stage of the Sino–Japanese War, Japan was trying hard to limit the conflict to within a scope where it could be resolved bilaterally between only the two nations involved. However, her actual behavior was in stark contrast to her wishful desire to be at peace with the United States, pushing the latter step by step instead in the direction of aiding China and thwarting Japan. Caught in a dilemma created as the United States abrogated the American–Japanese Treaty of Commerce and Navigation, and faced with the changes in the European situation, Japan’s policy makers were eventually pushed by their obsession with the “New East Asian Order” and by their yearning for the “Extended New East Asian Order” which was to include Southeast Asia, deciding to steer the Sino–Japanese War in the direction of “international resolution,” which was just an alternate route to the same goal sought by China. Subsequently, not only did Japan refuse to withdraw from China, she actually took one step further in an expansion southwards, trying to kill several birds with one stone. The war thus spilled over from China to encompass a much greater area. In this process, Japan’s diplomatic corps was often several steps ahead of the military, reflecting the carefully considered background in Japanese policymaking.
