Trump said Monday that he has cut a deal with chipmaker Nvidia, allowing it to sell certain artificial intelligence chips to China in exchange for a cut of the revenue, which would go to the U.S. government. Trump said he also negotiated a similar deal with chipmaker Advanced Micro Devices (AMD).

Nvidia struck a surprising deal after convincing the president that H20 chips aren’t a national security risk. But whether the reversal is good or bad depends on who you ask.

For years, the US has restricted the sale of powerful AI chips to China. But Trump is letting sales of less-advanced chips happen.
