“Did you believe that you were prohibited in any way from giving these disks to your brother?” Kaye asked. “No, I did not believe,” Mak said. Authorities believe Mak, a naturalized U.S. citizen, took thousands of pages of defense documents from his defense contractor employer, Power Paragon of Anaheim, and gave them to his brother, who passed them along to Chinese authorities over a number of years. Mak was arrested in 2005 in Los Angeles after FBI agents stopped his brother and sister-in-law as they boarded a flight to Hong Kong. Investigators said they found three encrypted CDs in their luggage containing documents on the propulsion system. Mak, 66, has pleaded not guilty to charges of conspiracy to export defense material to China, failure to register as a foreign agent, attempted and actual export of defense articles and making false statements. SANTA ANA – A Chinese-American engineer accused of conspiring to export defense technology materials to China took the witness stand in his federal trial Tuesday and denied he was trying to give information to the Chinese government. Defense attorney Ronald Kaye immediately asked defendant Chi Mak about three computer disks containing material presented at technical conferences including a submarine propulsion system called quiet electric drive. “Did you give the three disks with the conferences on them to your brother in order for them to be given to the Chinese government?” Kaye asked. “No,” said Mak. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
