President Donald Trump has sent letters this week outlining higher tariffs countries will face if they don’t make trade deals with the U.S. by Aug. 1.

Trump on April 2 proposed a 20% tariff for EU goods and then threatened to raise that to 50% after negotiations did not move as fast as he would have liked, only to return to the 10% baseline. The EU has 27 member states, including France, Germany, Italy and Spain.
