Chinese-Canadian scientists Xiangguo Qiu and Keding Cheng were fired from Canada's National Microbiology Laboratory (NML) in early 2021 under mysterious circumstances. Recently released documents by the Canadian Security Intelligence Service (CSIS) reveal they were dismissed for providing confidential scientific information to China. The documents indicate secret meetings with Chinese officials and intentions to transfer scientific knowledge and materials to China, posing a real and credible threat to Canada's economic security. Qiu and Cheng were also found to have an undisclosed bank account in China, receiving approximately CAD 1.2 million as part of the "Thousand Talents Program." The investigation highlights concerns over loyalty and adherence to security protocols. The case continues to be investigated for potential national security implications. #XiangguoQiu #KedingCheng #NationalMicrobiologyLaboratory #SecurityConcerns
