Arrest at SHAPE
Belgian authorities have arrested a Canadian woman on suspicion of espionage at the Supreme Headquarters Allied Powers Europe (SHAPE), NATO’s military headquarters in Mons, Belgium — and CBC News has identified her as Biwei Zhang, a systems engineer who previously held positions at the Canadian Space Agency, Statistics Canada, the World Trade Organization, and the European Space Agency. Zhang was arrested on Friday following a search of her home and workplace at SHAPE the previous Thursday, according to a media release from the Belgian Federal Prosecutor’s Office. She faces charges of espionage and participation in a criminal organization, charges that Public Safety Minister Gary Anandasangaree has described as “quite serious.”
Who Is Biwei Zhang?
Zhang’s online professional profile describes her as a systems engineer with a background in economics. Belgian prosecutors had described the suspect only as a “Canadian national of Chinese origin” serving as an intern in SHAPE’s IT department — a description that CBC News matched to Zhang through open-source investigative techniques, including her LinkedIn, Facebook, and Threads profiles, her graduate thesis, and a federal court case. While Biwei Zhang appears to be her legal name, she is known professionally as Claire Zhang and uses the name Catina Zhang on Facebook. A security source cited by Reuters earlier this week had identified the suspect as Claire Z., consistent with CBC’s findings.
Zhang’s social media activity provided additional corroborating details. In July 2025, she posted in two separate Facebook groups seeking a room to rent in Mons, coinciding with the start of her SHAPE internship. A similar pattern appeared in 2023, when she sought housing in Geneva just before beginning an internship at the World Trade Organization — dates that align precisely with the work history listed on her LinkedIn profile. These breadcrumbs of ordinary life, cross-referenced with the Belgian prosecutor’s description, formed the basis of CBC’s identification.
The Significance of Intern Access
Former CSIS intelligence officer Dan Stanton offered context on why intern positions at institutions like SHAPE can be attractive to foreign intelligence services. Stanton noted that internships frequently serve as an “in-road” for intelligence gathering, because critical secrets are often obtained through casual conversations and incidental access rather than through direct theft of classified files. The nature of such access makes it difficult to detect in real time, yet the fact that Belgian counter-espionage services identified and acted on the suspected activity is, in Stanton’s view, evidence that existing counter-espionage processes are functioning as intended.
Institutional Responses
Belgian courts do not publicly identify defendants in criminal investigations until a trial begins, and the Federal Prosecutor’s Office declined to confirm Zhang’s identity to CBC News, citing its policy of never disclosing the identities of individuals suspected in ongoing investigations — an approach it characterized as grounded in the presumption of innocence, which must be guaranteed under all circumstances. Global Affairs Canada also declined to comment specifically on Zhang’s case, citing the ongoing investigation. Public Safety Minister Gary Anandasangaree, however, committed publicly to getting “to the bottom” of the arrest, signalling that the federal government is treating the matter with considerable seriousness.
The case raises broader questions about security vetting procedures for international interns at sensitive allied military installations, and about the extent to which Canadian institutions that previously employed Zhang — including the Canadian Space Agency and Statistics Canada — may be drawn into the investigation. Neither of those agencies has commented publicly on the matter.
