China has a new trade boss.

The government said Li Chenggang is the new person.

Two big countries put more tax on things they sell to each other.

China's economy is big. It is growing. Maybe it will grow slower later.

China sells things to other countries. This helps China. China wants to grow 5% this year.

China is angry at the U.S. China puts a big tax on things from the U.S. But China wants to trade with other countries.

A man said new taxes are bad for China now. But not bad later.

China changed people for talks. We don't know why. China has many people to buy things. China can sell to other countries. But people in China don't buy much now. China needs people from the US to buy things.

China said some things cannot go out. These things are for computers and planes.

Before, Li was China's boss for trade.

He worked for China at the UN in Geneva.

He worked at the Ministry of Commerce.

Li studied law in China. Li studied law and money in Germany.
