BRUSSELS — Belgian prosecutors announced that a 52‑year‑old man holding both Chinese and Belgian citizenship has been kept in pre‑trial detention since May on suspicion of espionage involving advanced semiconductor technology. The suspect previously served as a senior executive at Belgan, a Belgian microchip company that specialized in gallium‑nitride semiconductors before it declared bankruptcy in July 2024.
Alleged Transfer of Sensitive Intellectual Property
According to the prosecution, the man simultaneously acted as a director of a newly formed Chinese company that produces the same type of gallium‑nitride chips. The Chinese firm was established only a few months after the suspect joined Belgan and was financed by a Chinese investment fund. Investigators allege that, in this dual role, he illegally transferred specialized intellectual property and trade secrets abroad.
Strategic Importance of Gallium‑Nitride Chips
Gallium‑nitride (GaN) chips are prized for their efficiency in high‑power applications, including electric vehicles, aerospace systems, and military hardware. The alleged theft therefore touches on national‑security concerns for both Belgium and its NATO allies, who view advanced semiconductor technology as a critical component of modern defense and clean‑energy initiatives.
Detention Details and Ongoing Investigation
The suspect was arrested at Zaventem airport in May while attempting to board a flight to Beijing. Prosecutors say he remains in detention while they continue to build their case. A second individual linked to the investigation is still at large, and authorities have not released further identifying information.
Diplomatic Context
The Chinese embassy in Belgium has not responded to requests for comment. The case adds to a growing list of European investigations into alleged technology‑theft operations linked to foreign actors, underscoring the heightened vigilance of law‑enforcement agencies across the continent.
Implications for the Belgian Tech Sector
While Belgan’s bankruptcy already dealt a blow to Belgium’s niche semiconductor industry, the espionage allegations highlight the vulnerability of high‑tech firms to foreign intelligence operations. Industry leaders have called for stronger safeguards around research and development, as well as clearer guidelines for employees with dual nationality who hold access to sensitive information.
Belgian officials have reiterated their commitment to protecting intellectual property and maintaining the integrity of the nation’s emerging high‑tech sector. The investigation remains ongoing, and further details are expected as prosecutors move toward formal charges.
