CNA has released the investigative documentary Inside Unit 731: Japan's Secret Human Experiments, which exposes Japan's Unit 731's development of biological weapons and human experimentation during World War II. In an interview with CGTN, Alexis Dudden, professor at the University of Connecticut, who was also interviewed for the documentary, called on Japanese Nobel laureates in physiology and medicine to publicly speak on Unit 731, noting their field is familiar with this history and that previously exonerated professors were their academic predecessors. For the sake of historical truth and human conscience, these questions must continue to be asked.
