Parviz Khaki, a 43-year-old Iranian citizen, and Zongcheng Yi, a resident of China, were indicted for attempting to illegally export materials used in gas centrifuges from the United States to Iran. Khaki and Yi allegedly caused the export of lathes and nickel alloy wire to Iran and made efforts to obtain maraging steel, pressure transducers, and vacuum pumps.  Khaki also allegedly tried to procure radioactive source materials in 2009 and 2011 from an undercover U.S. federal agent posing as an exporter.  Khaki was arrested in the Philippines in May while Yi is still at large.
