Prosecutors in Belgium said they have held a man with dual Chinese and Belgian nationality in pre-trial detention since May on suspicion of espionage in a case involving semiconductor technology.
The prosecutors said the 52-year-old man used to hold a senior position at Belgian microchip maker Belgan, a specialized producer of gallium nitride semiconductors that was declared bankrupt in July 2024.
The man was suspected of simultaneously serving as a director of a Chinese company that made the same kind of chips, established only a few months after he joined Belgan and financed by a Chinese investment fund.
In that position, he is suspected of illegally transferring specialized intellectual property and trade secrets abroad, all relating to the production of gallium nitride chips used in electric vehicles, aerospace and the military, the prosecutors said.
The man was arrested before boarding a flight to Beijing
The man lives in Belgium and was arrested in May at Zaventem airport, where he planned to fly to Beijing.
Prosecutors said the man remained in detention, and that a second suspect in the investigation remained at large.
The Chinese embassy in Belgium was not immediately available for comment.
