Some senior officials in the Trump administration are blocking completion of a landmark agreement that would let the United Arab Emirates buy advanced artificial-intelligence chips from Nvidia, the Wall Street Journal reported, citing people familiar with the talks. The multibillion-dollar deal, endorsed by President Donald Trump to support the Gulf state’s data-center expansion, would ship Nvidia’s most powerful graphics processors to the UAE. Hold-outs inside the White House and the Commerce Department fear the technology could be re-exported to China, particularly through Abu Dhabi-based AI specialist G42. Negotiators are now rewriting the terms so that no chips go directly to G42, underscoring the broader challenge of advancing Trump’s Middle-East AI strategy while keeping cutting-edge semiconductors out of Beijing’s reach. It remains unclear when—if ever—the revised accord will be signed.
