The Trump administration has issued export licences allowing Nvidia Corp. and Advanced Micro Devices Inc. to resume sales of certain artificial-intelligence chips to China, including Nvidia’s H20 accelerator and AMD’s MI308. The decision follows months of lobbying by Nvidia Chief Executive Officer Jensen Huang, who met with President Donald Trump in Washington last week. In exchange for the licences, the two chipmakers agreed to pay the U.S. government 15 percent of revenue generated from the authorised China shipments. Trump confirmed the arrangement on Monday, calling it a prerequisite for lifting earlier restrictions imposed on the chips for national-security reasons. White House press secretary Karoline Leavitt said the revenue-sharing model currently applies only to Nvidia and AMD but “perhaps it could expand” to additional companies. She added that the Commerce Department is still determining the legal basis and mechanics of the programme, an unprecedented move that trade lawyers say is likely to draw close scrutiny. The deal leaves Nvidia facing fresh uncertainty in its largest overseas market as Beijing officials press Chinese tech giants to favour domestic alternatives for sensitive work, according to reports from Reuters and the Financial Times. Nvidia generated roughly US$17 billion in China sales last year, underscoring what is at stake as Washington and Beijing recalibrate rules governing advanced semiconductor technology.
