China is big in the world. The old way is not strong. China does new things. It goes to new places.
China talks with Japan. China builds things in the UK. This shows China is changing.
Some people think the US is not strong. This helps China. But China has problems. Denmark and the US say no. They do not want China to build airports.
China and Japan have problems too. Japan's leader talks about fighting. China thinks Taiwan is its land. China says people should not go to Japan. Fewer people go to Japan now.
A new China house is in London. Some people worry. The UK leaders say yes. They will be safe. The UK leader will visit China. They will talk.
