The trial of the Japanese perpetrators was held in Khabarovsk in December 1949; a lengthy partial transcript of trial proceedings was published in different languages the following year by the Moscow foreign languages press, including an English-language edition.Materials on the Trial of Former Servicemen of the Japanese Army Charged with Manufacturing and Employing Bacteriological Weapons (Moscow: Foreign Languages Publishing House, 1950). (French language: Documents relatifs au procès des anciens Militaires de l'Armée Japonaise accusés d'avoir préparé et employé l'Arme Bactériologique / Japanese language: 細菌戦用兵器ノ準備及ビ使用ノ廉デ起訴サレタ元日本軍軍人ノ事件ニ関スル公判書類 / Chinese language: 前日本陸軍軍人因準備和使用細菌武器被控案審判材料) The lead prosecuting attorney at the Khabarovsk trial was Lev Smirnov, who had been one of the top Soviet prosecutors at the Nuremberg Trials. The Japanese doctors and army commanders who had perpetrated the Unit 731 experiments received sentences from the Khabarovsk court ranging from 2 to 25 years in a Siberian labor camp. The United States refused to acknowledge the trials, branding them communist propaganda.Takashi Tsuchiya. "The Imperial Japanese Experiments in China". The Oxford Textbook of Clinical Research Ethics, pp, 35, 42. Oxford University Press, 2011. The sentences doled out to the Japanese perpetrators were unusually lenient by Soviet standards, and all but two of the defendants returned to Japan by the 1950s (with one prisoner dying in prison and the other committing suicide inside his cell).
