The first 18 volumes of Part II deal with Japan from August 1914 through December 1939-a critical period in Japan's emergence as a world power. Among the topics discussed are Japan's Twenty-one Demands to China, growing suspicion of Japan's war aims, the Anglo-Japanese alliance, Japan's economic and political exploitation of Korea, strained Japan-U.S. relations, background material on the Washington Conference, Japanese interests and activities in the Philippines, and Japanese imperialism in China. Two volumes deal with the Sino-Japanese War.
Volumes 19-35 center on China. The editor has emphasized selections from the 1920s, reflecting the bulk of the total Confidential Print for China, and has omitted material that has appeared in the Japan volumes in this series.
