The Justice Department unsealed charges Wednesday against a suspected Chinese spy for allegedly conducting economic espionage and trying to steal trade secrets from U.S. aerospace companies.
The alleged Chinese intelligence officer, Yanjun Xu, was extradited to the United States on Tuesday from Belgium, where he was arrested in April at Washington's request.
His extradition marks what appears to be the first time that a Chinese spy has been brought to the U.S. to face prosecution, according to U.S. officials.
