President Donald Trump’s flurry of artificial intelligence deals during his tour of the Middle East is opening a rift within his own administration as China hawks grow increasingly concerned the projects are putting US national security and economic interests at risk.

Saudi Arabia, long viewed as a fountain of cash for the tech industry, has flipped the script, getting U.S. companies to fund its build-out of artificial intelligence. President Donald Trump announced hundreds of billions of dollars in deals when he visited Riyadh this week.

Nvidia, AMD, AWS, and others struck $100 billion in AI deals this week, aiming to profit from cheaper power and faster access to the growing Middle Eastern market for IT services.
