“Shortly before President Trump met Chinese leader Xi Jinping in South Korea, an urgent issue emerged. Trump wanted to discuss a request by Nvidia Chief Executive Jensen Huang to allow sales of a new generation of artificial-intelligence chips to China,” the Wall Street Journal reports.“Greenlighting the export of Nvidia’s Blackwell chips would be a seismic policy shift potentially giving China, the U.S.’s biggest geopolitical competitor, a technological accelerant. Huang—who speaks to Trump often—has lobbied relentlessly to maintain access to the Chinese market.”“As they prepared to meet Xi, top officials including Secretary of State Marco Rubio told Trump the sales would threaten national security, saying they would boost China’s AI data-center capabilities and backfire on the U.S.”
