Nvidia CEO Jensen Huang met with US President Donald Trump at the White House on Wednesday and agreed to give the federal government the cut from its revenues, a highly unusual arrangement in the international tech trade, according to reports in the Financial Times, Bloomberg and New York Times.

AFP was not able to immediately verify the reports.

Investors are betting that AI will transform the global economy, and last month Nvidia -- the world's most valuable company and a leading designer of high-end AI chips -- became the first company ever to hit $4 trillion in market value.

The California-based firm has, however, become entangled in trade tensions between China and the United States, which are waging a heated battle for dominance to produce the chips that power AI.

The US has been restricting which chips Nvidia can export to China on national security grounds.

Nvidia said last month that Washington had pledged to let the company sell its "H20" chips to China, which are a less powerful version the tech giant specifically developed for the Chinese market.

The Trump administration had not issued licenses to allow Nvidia to sell the chips before the reported White House meeting.

On Friday, however, the Commerce Department started granting the licenses for chip sales, the reports said.

Silicon Valley-based Advanced Micro Devices (AMD) will also pay 15 percent of revenue on Chinese sales of its MI308 chips, which it was previously barred from exporting to the country.

The deal could earn the US government more than $2 billion, according to the New York Times report.

The move comes as the Trump administration has been imposing stiff tariffs, with goals varying from addressing US trade imbalances, wanting to reshore manufacturing and pressuring foreign governments to change policies.

A 100 percent tariff on many semiconductor imports came into effect last week, with exceptions for tech companies that announce major investments in the United States.
