Belgian Prosecutors Detain Researcher and Probe Alleged Chinese Espionage at Bankrupt Chipmaker BELGAN
BLUFEurope's weak oversight of insolvent dual-use firms let gallium nitride IP migrate to a Chinese rival largely undetected, and apprehension of the second suspect by March 2027 remains unlikely.
Belgian federal prosecutors said they have held a 52-year-old Belgian-Chinese national in pre-trial detention since May 10, when he was arrested at Zaventem airport boarding a flight to Beijing 12. Prosecutors said the man held a senior research post at BELGAN, a gallium nitride chipmaker that went bankrupt in July 2024, while simultaneously serving as a director of a similarly focused Chinese company established months after he joined BELGAN and financed by a Chinese investment fund 13. Investigators are examining suspected unlawful transfer of specialized intellectual property and trade secrets on gallium nitride chip production, technology used in electric vehicles, aerospace, and military applications 1. Prosecutors told Euronews a second suspect remains at large, and Belgian broadcaster RTBF reported the detained man denies the charges 3.
AnalysisThe case exposes a structural gap in Europe's oversight of insolvent dual-use technology firms, where foreign-financed board seats and post-bankruptcy management changes let sensitive gallium nitride IP migrate to a China-based rival largely undetected until after the transfer occurred. Belgian authorities are
unlikely to apprehend the second suspect by March 8, 2027, given his presumed departure for China and Beijing's pattern of non-cooperation on extradition in comparable cases, leaving prosecutors to reconstruct the technology-transfer network from documents rather than testimony. Moderate confidence reflects converging but still-developing reporting on prosecutorial intent, drawn largely from three wire-style accounts tracking a single prosecutorial statement, without independent confirmation of the second suspect's whereabouts. The prosecution could instead reflect Belgium's broader push to recast a commercial bankruptcy and IP dispute as state-directed espionage amid heightened EU scrutiny of Chinese investment. His capture would let EU investment-screening bodies close out the network and calibrate rules on foreign stakes in insolvent dual-use chipmakers, while his continued absence forces tighter export and investment controls on an incomplete picture.
