Ask what Korea is talking about.

Nvidia said on Sunday it is probing whether CEO Jensen Huang was the target of a foreign intelligence effort, after a media report alleged he had a close relationship with a Chinese businesswoman who passed information, the Korea Times reports. The New York Times reported on Oct. 29 that U.S. intelligence assessed a Chinese executive at a Singapore-based data center company who had close contact with Huang as a Chinese intelligence asset, Business Korea reports. Huang admitted the affair to employees a day after a Financial Times exposé, and Nvidia formed an independent investigation committee to check for leaks, Maeil Business Newspaper reports. House Republicans have also requested a closed-door briefing with Huang, Business Korea reports. Separately, Huang's daughter Madison, a senior Nvidia director, abruptly canceled a planned visit to South Korea, according to Yonhap and the Korea Times.
