A Chinese businessman has been indicted in California on charges he hacked the computer systems of Boeing and other US defence contractors and stole confidential plans for military aircraft.
According to the indictment in federal court in Los Angeles, Su Bin travelled to the United States at least 10 times between 2008 and 2014 and worked with two unidentified co-conspirators based in China to steal the data.
Prosecutors said the trio stole plans relating to the C-17 military transport plane and F-22 and F-35 fighter jets, and tried to sell them to Chinese companies.
Su is charged with unauthorised computer access, stealing trade secrets and violating federal laws that require a licence from the US State Department to export defence-related technical data.
If found guilty he faces up to 30 years in prison.
Su was arrested in June in Canada, where he was attempting to establish residency, according to the Federal Bureau of Investigation.
US officials say industrial spying is a growing threat.
Federal prosecutors in May charged five Chinese military officers with hacking into American companies to steal trade secrets.
China, angered by those allegations, shut down a bilateral working group on cybersecurity.
