China has released a set of archives, revealing something some countries still haven't fully reckoned with. These are newly declassified Soviet files on Japan's Unit 731, one of the most horrific military programs of World War II.

The files include interrogation transcripts, internal memos and investigation notes from 1939 to 1950, detailing a state-run system for biological weapons.

We're talking:
— freezing humans to study frostbite
— vivisections with no anesthesia
— infecting people with plague, anthrax, cholera, typhoid
— civilians and prisoners of war, Chinese, Koreans, Mongolians, Russians, used as living test subjects

These archives from Russia line up perfectly with what China has preserved for years, forming a complete evidence chain that Japan's biological warfare was a deliberate, systematic state crime. This release helps ensure the truth stays on the record and the victims of these crimes are never erased.
