Companies in Europe make medicines. They sell a lot of these medicines to the U.S. The companies are worried now. The U.S. has a new rule. This rule is a tax on things from other countries.
This new tax is called a tariff. It can make the medicines more expensive. The companies in Europe do not want to pay this tax. They are not sure what will happen.
However, the companies are also a little hopeful. They have many business deals in the U.S. They have also spent a lot of money in America. They hope this will help them avoid the new tax.
