Belgium Detains Dual National Over Alleged Gallium Nitride Chip Secrets Transfer

Belgian prosecutors said Monday they have held a 52-year-old dual Chinese-Belgian national in pre-trial detention since May on suspicion of espionage and the unlawful transfer of gallium nitride (GaN) semiconductor know-how to a Chinese firm, a case that has sharpened European concern over industrial secrets. Officials said the man, who has not been publicly named, was arrested at Brussels Zaventem Airport just before a flight to Beijing and remains in custody; a second suspect is still being sought.
