Collaboration: Japanese Agents and Local Elites in Wartime China is a history book which investigates collaboration between the Chinese elites and Japanese, following the attack on the Chinese city of Shanghai in August 1937, just before the outbreak of the Second World War, and during the subsequent military occupation of the Yangtze River Delta in China by Japan. The book is written by Timothy Brook, a distinguished Canadian historian who specializes in the study of China (Sinology).
