China's Foreign Ministry has rejected allegations involving Nvidia CEO Jensen Huang as "fabricating so-called spy narratives" used to justify US tech restrictions. Chinese Foreign Ministry spokesperson Mao Ning made the comments at a press briefing on Thursday, saying Beijing was willing to work with the United States to implement agreements reached by Presidents Xi Jinping and Donald Trump to ease tariffs and lift restrictions on technology.

Huang has admitted to an extramarital affair with a woman US officials believe worked for Chinese intelligence. The woman was identified as Alice Huang, a former executive at Singapore-based Megaspeed. China's Ministry of Foreign Affairs has called the claims "entirely groundless, speculative and intended to smear and malign China."

Nvidia launched an investigation into Huang on Sunday. The 63-year-old co-founder has long opposed curbs on US chip sales to China. Last year Trump cleared Nvidia's H200 chips for export to China despite objections from lawmakers concerned about Chinese AI dominance.

Megaspeed said Thursday it takes compliance with US export control laws "extremely seriously" and is "committed to working constructively and transparently with the US government."

Huang's position at the head of the $4.2 trillion company remains uncertain. It is unclear whether Nvidia has a succession plan.
