President Trump has put tariffs on products from China, which are extra costs added to the price of goods. China responded by putting tariffs on some American products too. They also investigated Google, a big company that helps people find information on the internet. The tariffs are meant to make China stop sending a drug called fentanyl to the United States. The Chinese government also made it harder for American companies to buy certain materials that are important for making high-tech products. President Trump wants to make sure America is treated fairly in trade with other countries. He also wanted to put tariffs on products from Canada and Mexico, but they promised to help stop the drug fentanyl, so he decided not to for now. Tariffs are like extra fees that make things more expensive. China and America are putting tariffs on each other's products because they are having a disagreement. Trump wants China to stop sending a drug to America, and he is using tariffs to try to make them do what he wants. This can make things more expensive for people in both countries. It is important for countries to trade with each other, but sometimes they have disagreements. Tariffs can be a way for them to try to solve their problems. It is like a game of give and take, where one country does something to another, and the other country does something back. This can make things seem more confusing, but it is one way that countries try to talk to each other and figure out their problems.
