Sihai Cheng, a Chinese national, was sentenced to nine years in prison for violating U.S. sanctions prohibiting the export of technology used to make nuclear weapons-grade uranium. According to the plea agreement, from 2009 to 2012, Cheng conspired to export, and ultimately exported, U.S.origin pressure transducers from the United States to Iran by way of China. The transducers can be used in gas centrifuges to enrich uranium. They cannot be shipped to China without a license and are prohibited for export from the United States to Iran.
