The United States says OK. Nvidia can sell some computer chips to China. This is a big change.
Nvidia makes good chips. One chip is called H200. It is strong. China can buy this chip now.
Before, China could not buy these chips. The US leaders wanted to slow China's growth. Now, China must show good use. They must not use chips for war.
The US also needs chips. They will only sell if they have enough. This is about business and safety.
This is good for AI. AI helps things get better. China can make AI systems. They might cost less.
Nvidia is a big company. They had problems with China. The US will not let China buy the newest chip.
Canada also wants to trade with China. Their leader is visiting China. They want to sell more things.
Trade and technology are important. They help countries work together. This shows how things change.
