Big company Nvidia cannot sell its chips in the U.S. because of new rules.

Nvidia needs special permission from the U.S. to send chips to China.

Nvidia thinks it will pay $5.5 billion next year. This is until April 27. The company's shares went down a little after the market closed.

The H20 is a good computer chip. Nvidia can send it to China.

Maybe it is not a surprise. Nvidia said on Monday they will make some AI chips in the U.S. for four years. They will spend a lot of money. Some people said the company did not give many details.

Some people in the government said we should not send a computer part called H20 to other countries. They said it was used to make AI in China.

Nvidia said nothing about this.
