Canadian Intern Arrested in Belgium Over Alleged Spying at NATO Headquarters
A Canadian woman of Chinese origin who worked as an intern at NATO’s primary military command centre in Belgium has been arrested on suspicion of espionage and membership in a criminal organization. Belgian authorities and multiple Canadian media outlets have identified her as Biwei Zhang, who professionally used the name Claire Zhang and appeared on social media as Catina Zhang. The case has raised serious questions about security screening processes in Canada and the broader risks of foreign interference inside Western institutions.
Zhang, who is in her thirties, was serving as an intern at the Supreme Headquarters Allied Powers Europe, commonly known as SHAPE, located in the Belgian city of Mons near the French border. SHAPE functions as NATO’s operational military headquarters, responsible for planning, directing, and coordinating the alliance’s military activities across Europe and beyond. According to security sources, she worked in the IT department and had been at the base for roughly a year after arriving in Mons in the summer of 2025. She had extended an initial six-month internship to a full year and was nearing its conclusion when investigators moved against her.
Belgian federal prosecutors announced that the suspect, described as a “Canadian national of Chinese origin,” is believed to have spied on behalf of a third country while also participating in a criminal organization. While official statements avoided naming the country, national-security sources speaking to Reuters, The Globe and Mail, and other outlets have indicated that investigators are examining allegations she acted for China. Chinese authorities have rejected the claims, with the foreign ministry accusing NATO of groundless accusations and smears. No public evidence has been released, and Zhang has made no statement. No lawyer has spoken on her behalf.
The investigation began after SHAPE’s own security services grew concerned about her behaviour. Reports from European media, citing security officials, said she had been observed lingering around NATO buildings and repeatedly asking hypothetical questions about security protocols and potential breaches. SHAPE referred the matter to Belgian intelligence services. On July 24, 2026, police searched her residence in Mons and her workplace inside the headquarters, assisted by computer-crime and forensic specialists. She was arrested the following day and placed in pretrial detention.
A closed hearing later extended her custody by one month. Zhang has appealed the decision to keep her detained, with a ruling expected within two weeks of the appeal filing. Under Belgian procedure, suspects in sensitive national-security cases are often not formally identified until charges advance further. NATO has stated that there is no indication the incident affected operational readiness, command-and-control systems, or ongoing missions. A SHAPE spokesperson emphasized that the headquarters continues to fulfill its responsibilities without interruption.
Zhang’s professional background is extensive and spans both Canadian government agencies and international organizations. She previously worked as an economist at Statistics Canada and as a systems engineer in the satellite operations department of the Canadian Space Agency. Her online profiles and resume also list experience at the World Trade Organization in Switzerland and the European Space Agency in Italy. She holds degrees in economics and engineering, including a master’s in computer science from the University of Ottawa completed in 2022. She is fluent in English, French, and Mandarin. Social media posts from July 2025 show her seeking accommodation in Mons as she prepared to begin the SHAPE internship.
The case has focused intense scrutiny on Canada’s security vetting procedures. Responsibility for screening nationals who apply for NATO internships rests with their home countries. Senior Canadian sources confirmed that Zhang underwent checks by the Canadian Security Intelligence Service and the RCMP before starting at SHAPE. Internships of this type typically do not require the highest levels of security clearance, which can take six to eight months to complete. Public Safety Minister Gary Anandasangaree has said the government will examine the screening process and “get to the bottom of what happened.” The RCMP has stated it is prepared to support the Belgian investigation but will not comment on an ongoing foreign probe.
Additional details about Zhang’s past have complicated the picture. In 2023, the Public Service Commission found that she had committed fraud by submitting two separate applications for a Canada Border Services Agency position under slightly different names and email addresses. The commission ordered her to complete an ethics course and to notify the watchdog in writing before accepting certain federal public-service roles for a period of one year. Despite that finding, she later secured positions at Statistics Canada and the Canadian Space Agency before obtaining the NATO internship. Critics have pointed to this sequence as evidence of gaps in how past misconduct is weighed during subsequent clearances.
The arrest comes at a sensitive moment for Canada-China relations. Ties had shown signs of gradual improvement under the current federal government, but allegations that a former Canadian public servant may have been recruited to gather information inside a core NATO facility risk reversing that progress. Security analysts note that China has become a growing concern for NATO, particularly regarding technology, cyber capabilities, and influence operations. Interns and junior staff often have access to conversations, systems, and environments that can yield valuable intelligence even without formal high-level clearances. Opportunity and proximity, rather than stolen classified files, frequently form the basis of successful espionage efforts.
For NATO, the episode underscores the challenges of managing a large multinational workforce that includes temporary and junior personnel. SHAPE employs thousands of staff and hosts dozens of interns each year. Allies rely on each member country to conduct thorough background checks. When those checks appear incomplete or insufficiently rigorous, trust across the alliance can be strained. Belgian investigators continue their work, and Canadian agencies have indicated they are monitoring developments closely.
Zhang remains in custody in Belgium. The allegations against her are serious but unproven in court. Belgian prosecutors have not yet laid formal charges beyond the initial suspicions of espionage and participation in a criminal organization. The investigation is ongoing, and further details may emerge as the legal process advances. In the meantime, the case has already prompted a public conversation in Canada about the adequacy of security screening for positions that provide access to sensitive allied institutions. How Ottawa responds to the questions raised by this episode will shape both domestic policy and perceptions among NATO partners in the months ahead.
