A U.S. government memo based on intelligence describes a romantic relationship between Nvidia Chief Executive Jensen Huang and Alice Huang, an executive at Megaspeed whom U.S. officials believe was recruited by China's Ministry of State Security, the Financial Times reported Friday, citing people familiar with the document. The memo, which the Financial Times said it had not seen but was described by sources, alleges the relationship occurred while Alice Huang held a senior position at Megaspeed, a company that supplies components to Nvidia. U.S. intelligence agencies assess that she was cultivated as an asset by the MSS, China's primary civilian spy agency, according to the Financial Times report.
