Belgian authorities have arrested a Canadian national of Chinese origin working as an intern at NATO’s Supreme Headquarters Allied Powers Europe (SHAPE) on suspicion of espionage. The detention was announced on Saturday by Belgium’s Federal Prosecutor’s Office, which stated the individual is suspected of spying on behalf of a third country and being part of a criminal organization. The specific country for which the suspect allegedly conducted espionage has not been disclosed.

The suspect was employed at SHAPE, NATO’s operational command center based in Mons, Belgium, near the French border. SHAPE is responsible for planning and directing joint military strategy, tactics, and operations among NATO member states and also hosts the alliance’s Cyber Security Centre. The exact division within SHAPE where the intern worked and the length of their employment remain unclear.

According to the prosecutor’s office, concerns about the individual’s activities were initially raised by SHAPE’s internal security services, which reported to the Belgian military intelligence agency, triggering a formal investigation. On Thursday, Belgian law enforcement officers executed searches of the suspect’s residence and workplace within NATO premises, assisted by specialized computer crime and forensic units. The arrest followed the day after the searches.

A spokesperson for SHAPE, Colonel Martin O’Donnell, stated that there was no evidence to suggest that operational readiness, command structures, or ongoing missions were compromised due to the arrest. He reaffirmed NATO’s continuing commitment to protecting classified information and maintaining the security and trust vital to the alliance’s functioning.

Canada’s Public Safety department confirmed the government’s awareness of the arrest but did not provide further details, citing the ongoing nature of the criminal investigation.

Belgium, which hosts several key European and international institutions including the European Commission and Parliament in Brussels, has a history of espionage concerns. Last year, Belgian police arrested a Brussels officer accused of spying, reportedly for both China and Russia. Furthermore, Belgian authorities have been investigating a 2023 cybersecurity breach affecting the country’s intelligence service, which has been linked to hackers with ties to Chinese espionage activities.

The arrest underlines persistent challenges faced by NATO and its member states regarding internal security and protection against foreign intelligence threats. Investigations are ongoing.
