This book contains eighteen studies on various important phases of Japan’s invasion of China. The appendix contains the historical declaration by Chiang-Kai-shek setting forth clearly the reasons why China took up arms against Japanese aggression, and a lucid chapter by the veteran sinologist Owen Lattimore on what Korea pays for Japan’s rule. Ever since the invasion of Manchuria by Japan in September 1931 the writer called attention to the fact that, in view of the League commitments, aggression in the East, if not properly stopped according to the League Covenant, would encourage aggression to spread beyond the limits of Asia.
