The Wall Street Journal: Despite ban, China nuclear-weapons lab has bought U.S. chips for years

SINGAPORE — China’s top nuclear-weapons research institute has bought sophisticated U.S. computer chips at least a dozen times in the past two and half years, circumventing decades-old American export restrictions meant to curb such sales. A Wall Street Journal review of procurement documents found that the state-run China Academy of Engineering Physics has managed to obtain the semiconductors made by U.S. companies such as Intel Corp.
and Nvidia Corp.
since 2020 despite its placement on a U.S. export blacklist in 1997.

The chips, which are widely used in data centers and personal computers, were acquired from resellers in China. Some were procured as components for computing systems, with many bought by the institute’s laboratory studying computational fluid dynamics, a broad scientific field that includes the modeling of nuclear explosions. Such purchases defy longstanding restrictions imposed by the U.S. that aim to prevent the use of any U.S. products for atomic-weapons research by foreign powers. The academy, known as CAEP, was one of the first Chinese institutions put on the U.S. blacklist, known as the entity list, because of its nuclear work. A Journal review of research papers published by CAEP found that at least 34 over the past decade referenced using American semiconductors in the research. They were used in a range of ways, including analyzing data and generating algorithms. Nuclear experts said that in at l …
