One of the most striking aspects of the international history of the 1930s is the revival and official endorsement of a pan-Asian vision of regional world order in Japan. The pan-Asian discourse of East-West civilizational difference and comparison was influential in various intellectual circles in Asia. But during the 1920s, as a political project of Asian solidarity, it was irrelevant for Japan's foreign policy, and it did not have any international momentum or movement. The period after the Manchurian Incident in 1931, however, witnessed a process by which pan-Asianist ideas and projects became part of Japan's official foreign policy rhetoric. After 1933 Japan's pan-Asian internationalism began to overshadow liberal internationalism, gradually becoming the mainstream vision of an alternative world order. This process culminated in the declaration of the Greater East Asia Coprosperity Sphere in 1940, a project that relied heavily on the rhetoric of pan-Asian internationalism. In 1943, seventeen years after the ineffectual 1926 Nagasaki pan-Asiatic conference that was ridiculed by official and liberal circles in Japan, the Japanese government itself hosted a Greater East Asia Conference to which it invited the leaders of the Philippines, Burma, the provincial government of India, the Nanking government of China, Manchukuo, and Thailand.
