President Donald Trump’s controversial plan to take a cut of revenue from chip sales to China has US companies reconsidering their plans for business with the country, offering a model for circumventing years of trade tensions.

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).

The government will take a 15% cut of the revenue the chip makers generate by selling certain chips to China, according to media reports.
