The Khabarovsk War Crime Trials were hearings held between 25–31 December 1949, in the Soviet Union's industrial city of Khabarovsk (Хаба́ровск), the largest city within the Russian Far East (Дáльний Востóк) adjacent to Japan. There, twelve members of the Japanese Kwantung Army were tried as war criminals for manufacturing and using biological weapons during World War II.
