US Secretary of State Marco Rubio raised concerns about the relationship between Nvidia CEO Jensen Huang and a business executive suspected of working for Chinese intelligence in a memo last spring, ahead of President Donald Trump's visit to China. The memo questioned Huang's association with Alice Huang, who US intelligence agencies believed was gathering information for Beijing. This development comes amid growing scrutiny of Nvidia's business dealings with China and concerns that advanced AI chips could be reaching the country through third-party companies. Initially left off the list of prominent executives invited to accompany Trump on his China trip, Huang was eventually included after Trump intervened. However, the decision to include him remains unclear. The intelligence concerns emerged at a time when Huang was seeking to maintain Nvidia's access to the Chinese market. It is reported that several administration officials were concerned about Huang's influence over Trump's approach to AI regulation. Despite the controversy, Nvidia has maintained that Huang's interactions with Alice Huang were routine and not unusual. The company has launched an investigation into the matter but maintains that no national security or company secrets have been compromised. Megaspeed, a Singapore-based company that purchased around $2 billion worth of Nvidia products in recent years, is under US scrutiny for its business dealings and suspected involvement in moving restricted advanced chips into China illegally. Alice Huang had connections with senior executives across the AI chip industry, including Jensen Huang and leaders of Gigabyte, a major assembler of Nvidia supercomputers.
