Decades after WWII, the horrors of Japan's Unit 731 remain.

China has received a batch of Russian-provided evidence related to Unit 731's wartime atrocities, including trial records of Unit 731 members, investigation reports on the unit's crimes, and internal official correspondence of Soviet authorities. The newly released files offer new evidence of the unit's wartime crimes and fuel the ongoing pursuit of truth and memory.
