This weekend, the leaders of major countries gathered together. They reached some agreements on important topics.
For example, about climate. The leaders agreed that carbon dioxide emissions should be halved by 2030. Carbon dioxide is a substance that warms the earth. The leaders hope to help poor countries also reduce carbon dioxide emissions.
They also reached an agreement with world leaders on coronavirus vaccination. They will provide a total of 1 billion vaccines to poor countries.
The leaders also talked about China. They think that China has become too powerful and want to stand together against that country. They also want to prevent forced labor. They are talking about Uighurs in China. But it is not clear how they plan to do this.
