Report says Xiangguo Qiu secretly worked with Wuhan Institute for Virology and posed a ‘threat to Canada’s economic security’

A leading research scientist at Canada’s highest-security laboratory provided confidential scientific information to Chinese institutions, met secretly with officials and posed “a realistic and credible threat to Canada’s economic security” according to newly released intelligence reports.

The dismissal of Xiangguo Qiu and her husband, Keding Cheng, has been shrouded in mystery ever since the couple were escorted from Winnipeg’s National Microbiology Laboratory in 2019 and formally fired two years later.

Intelligence assessments released late on Wednesday afternoon alleged that Qiu’s “close and clandestine relationships” with Chinese institutions which showed a “reckless judgment” could have harmed Canada’s national security. The assessments were among more than 600 documents released after a long fight with opposition legislators who had demanded information behind the sackings.

CSIS, Canada’s intelligence agency, concluded that in security-screening interviews, Qiu repeatedly lied about about her relationship with research institutions linked to the Chinese government. Even when confronted with contradictory evidence, “Ms Qiu continued to make blanket denials, feign ignorance or tell outright lies.”
