Ask what Korea is talking about.

Nvidia's CEO Jensen Huang admitted to an extramarital affair with a Chinese businesswoman alleged to be a spy for Beijing, triggering an internal investigation and a market selloff that wiped out about $430 billion to $470 billion in value over two sessions, the Korea Times reports. The scandal has raised national security concerns in the U.S., with calls to tighten semiconductor export controls just days before President Donald Trump's summit with China, according to analysts quoted by the Korea Times. A shareholder has also sued Nvidia and Huang, accusing them of deceiving investors about the affair, the Korea Times adds. Korean media, including Business Korea, report the fallout is spreading to the auto industry, which closely watches Nvidia's chips, and warn the controversy could test the fragile US-China truce.
