Leaders in Europe are trying to stop the US from putting a 50% tax on things they buy from Europe. The US President is unhappy because Europe sells more to the US than it buys. This means the US loses money. Europe says that if you include online services, the US sells more to Europe. To change this, Europe could buy more gas from the US, spend more on US weapons, or make taxes on US cars lower. But, it is hard to agree on Europe's rules for food and its taxes. Experts think that if the 50% tax happens, Europe's economy could become 1% smaller next year, and companies might spend 6% less money.
