US Tech giant Nvidia: spy scandal

US chip giant Nvidia has said it is investigating reports that its CEO Jensen Huang had a close relationship with Alice Huang, who had been the managing director of Singapore-based data centre company Megaspeed. The New York Times reported that US officials suspect Alice Huang has been working for China's spy agency to collect intelligence. China has denied allegations of Huang being a Chinese spy, calling the allegations "entirely groundless, speculative and intended to smear and malign China."
