Ask what Korea is talking about.

Nvidia shares declined on Monday after the company launched an internal investigation into whether CEO Jensen Huang was targeted by a foreign intelligence effort, following a media report alleging a close relationship with a Chinese businesswoman accused of passing information to Beijing. Huang has admitted to an affair with Alice Huang, a businesswoman suspected of working as a spy for the Chinese government, according to KBS World. The board of directors announced the probe in a statement on Sunday, and the controversy has raised security concerns, with Business Korea reporting that the global automaker industry is also closely watching the situation. In Korea, the scandal has sparked uncertainty in the chip sector, with industry officials concerned it could affect the U.S. AI semiconductor ecosystem and Nvidia's partnerships with Korean firms, the Korea Times reports. Huang's past TV appearance with his wife has also resurfaced in Korea, drawing renewed attention amid the affair scandal.
