During the discussion session, an archaeology student asked why no systematic archaeological excavation had been carried out at the former Imperial Japanese Army Medical School site, where some Unit 731 victims" remains were found. Kawamura replied that police had taken control of the site immediately after the discovery of the remains, disturbing the original strata, and that comprehensive archaeological investigations and efforts to identify the victims have remained stalled ever since.

　　Speakers contrasted the sustained efforts of civic groups with what they described as the Japanese government"s continued reluctance to fully confront the legacy of its wartime biological warfare program.

　　The Japanese newspaper Kitanippon Shimbun once reported that as firsthand witnesses of wartime events continue to decline, narratives that deny or downplay Japan"s "negative history" and its "past acts of aggression" have been gaining ground.

　　It is alarming that, in the face of ironclad facts, the Japanese right wing forces not only refuse to repent, but also whitewash the infamous Unit 731 as mere a "sanitary research unit," engage in brazen historical revisionism and go to great lengths to cover up the truth while downplaying and denying their guilt. Their real purpose is to negate the judgement of history and challenge the post-war international order based on the victorious outcomes of WWII, which poses a threat to regional peace and stability, Chinese Foreign Ministry spokesperson Lin Jian said on June 18 when responding a question related to Japan"s Unit 731.

　　Japanese militarists used germs to bring about large-scale destruction of human lives, in flagrant violation of universally recognized international law, including the Hague Convention (IV) of 1907 and the Geneva Protocol of 1925. The inhumane nature of these acts is nothing but horrendous, Lin said.
