A review of the lab’s public records and internal guidelines reveals the existence of unspecified classified projects and discussion of the lab’s responsibilities under China’s state secrets law. Some records mention protocols for disclosing information to foreigners and the sealing of some research reports for up to two decades... The Wuhan lab’s guidelines on information disclosure say the institute shares details of its work with the public, with the exception of state secrets, research and work secrets, matters under investigation, and disclosures that would violate the law. The topics of the lab’s classified projects are unknown. The lab and the National Administration for the Protection of State Secrets did not respond to questions on the matter. The U.S. State Department said in January that the Wuhan lab had worked on classified projects, including animal experiments, with China’s military since at least 2017. The Washington Post was unable to independently confirm that, but found public records of the lab working with Chinese military hospitals on unclassified projects for drug development and AIDS prevention, as well as instances in which lab officials mentioned classified projects at the institute.
