Otto Braun was a German communist journalist and functionary of the Communist Party of Germany with a long and varied career. His most significant role was as a Comintern agent sent to China in 1934 to advise the Chinese Communist Party (CCP) on military strategy during the Chinese Civil War. At the time Braun adopted a Chinese name, Li De. It was only many years later that it became known that Otto Braun and "Li De" were the same person.
