President Trump has decided to put new taxes on things that come from China. This makes it hard for China to decide what to do. They might look weak if they do nothing, but if they fight back, it could start a big problem for everyone. China has been doing well by selling a lot of things to other countries. They made almost $1 trillion more from selling things than they spent buying things last year. But now, with these new taxes, things could change. China said they will fight these taxes by talking to a group called the World Trade Organization. This group tries to stop countries from doing things that are not fair in trade. But the World Trade Organization doesn't have as much power as it used to. It can't do much without judges to help make decisions. Some people in China thought President Trump would focus on other countries, not them. But now, they are facing these new challenges. It's a tricky situation for everyone involved.
