The leaders in the US made a new rule. Now, a company called Nvidia can sell special computer parts to China. This makes it easier to sell things.
Before, the rules were hard. The US leaders were worried. They thought China might use the parts for its army. So, they stopped selling the best parts.
Now, Nvidia can sell different parts. These parts are not as strong. It is good for jobs in the US.
Some people are happy. They think this helps money for the US. Other people are not happy. They worry about safety. They think China might use the parts to watch people.
The US and China want new technology. This new rule is important. We will see what happens next.
