Jensen Huang, chief executive of US technology giant Nvidia, is alleged to have had an affair with Chinese businesswoman Alice Huang. US authorities suspect that she spied for Beijing during their relationship and entered Taiwan eight times over the past two years. Taiwan’s Executive Yuan has confirmed that Taiwan is working with the US to investigate the matter.

According to reports by Taiwan’s Liberty Times (《自由时报》) and Economic Daily News (《经济日报》), Executive Yuan spokesperson Michelle Lee told a press conference after a cabinet meeting on Thursday (12 November) that the case involved a “cross-border joint investigation” and that no further details about the individual case could be provided at this stage. If criminal offences were involved, she added, the confidentiality rules governing investigations would also prevent further disclosure.

Lin Yi-chun, head of the National Immigration Agency’s Entry and Exit Affairs Division, said the agency had worked with national security agencies to track Alice Huang’s visits to Taiwan. Her entry permit has now been revoked and she has been barred from entering Taiwan. He declined to elaborate as the case was under investigation.

Lin said the government had an established screening mechanism for people of specified categories visiting Taiwan, including pre-entry checks, visits during their stay and follow-up action after their departure.

Asked how the authorities would prevent mainland Chinese nationals from using Hong Kong visas or business visits to enter Taiwan for espionage, Lee said national security agencies would screen entrants and conduct visits through inter-agency review mechanisms and on the basis of relevant intelligence. If investigations established that an entrant had engaged in espionage or activities inconsistent with the original purpose of their entry permit, the permit would be revoked in accordance with the law and a national security investigation launched.

Taiwanese media reported that Mainland Affairs Council Minister Chiu Chui-cheng told the legislature’s Internal Administration Committee on Thursday that Alice Huang had entered Taiwan five times in 2025 and three times in 2024. There was no record of her entering Taiwan this year.

Chiu confirmed that Alice Huang had visited Taiwan for business as a Hong Kong resident. He said that, now that the Taiwanese authorities knew her identity, they would flag her record and restrict her entry in accordance with the Regulations Governing Permits for Hong Kong and Macau Residents to Reside or Settle in Taiwan, on the grounds that she could pose a threat to Taiwan’s interests, public safety or public order.

Bloomberg on Thursday cited people familiar with the matter as saying that Alice Huang had returned to mainland China and was now living in Beijing.
