US President Donald Trump has acknowledged that he was made aware of a memo, penned by Secretary of State Marco Rubio, which flagged an alleged romantic relationship between Nvidia CEO Jensen Huang and a Chinese operative. However, Trump claims he did not recall reading the document during his visit to Beijing in May. The FBI is currently investigating this association, with Alice Huang (also known as Huang Le) being the suspected operative. Despite the allegations, Trump has publicly defended Jensen Huang, stating that he believes the tech mogul when he said he was unaware of Alice Huang's espionage activities. The investigation has raised concerns about potential transfer of sensitive intellectual property and has added to questions regarding when the US administration became aware of this alleged connection and what action was considered. The controversy surrounding Jensen Huang's lobbying for relaxed export controls on Nvidia's semiconductor shipments to mainland China has also drawn international scrutiny. China, however, has dismissed the espionage allegations as part of a coordinated smear campaign against Beijing.
