Donald Trump is changing world rules. He talks to friends now. He told a neighbor country about money. He will let a rival country have good things. These actions are big. People in charge are surprised.
Trump thinks some countries do not help. This is for a war. He says they "talk but do not do." Leaders say they help. One leader wants to work together.
Trump also spoke to Mexico. They talked about water. Trump said Mexico does not send water. He will tax Mexican things. This makes problems for the two countries.
America will let China buy new things. This is a big change. The leaders are making new rules. One company can now send things to China. Some people think this is good.
But, some people worry. They worry China can use this for its army. They also worry China can watch its people. They think money is more important than safety. This could make America's things weaker.
These actions use money. But they can make problems with friends. It is not clear if these actions will help.
