European Union officials are working to prevent the Trump administration from putting a 50% tax on imported goods. The U.S. President has often said he is unhappy that Europe sells more goods to the U.S. than it buys, creating a trade imbalance. The EU argues that if digital services are included, the U.S. actually sells more than it buys, making the trade even. To change the trade in goods, the EU could buy more liquefied natural gas from the U.S., spend more on defense with U.S. companies, or lower its 10% tax on foreign cars. However, it has been hard to solve problems related to European rules on food and farm products, and the sales taxes used by European governments. Economists predict that if these 50% tariffs are put in place, the combined economy of the eurozone countries could shrink by up to 1% next year, and business investment could drop by more than 6%.
