BANGKOK (AP) — China is denying that there is any spy plot targeting Nvidia CEO Jensen Huang, and is calling it a smear campaign against Beijing. Huang admitted to an extramarital affair but did not name anyone. The controversy centers on whether he drove sales of advanced computer chips to China, despite U.S. tech restrictions. The New York Times reported that Huang had a close relationship with a Chinese citizen accused of smuggling chips into China. China’s Ministry of Foreign Affairs spokesperson dismissed the spy allegations on Monday as unsubstantiated. Huang had lobbied U.S. President Donald Trump to loosen chip sales restrictions to China.
