Online reports that Dan Marani, former U.S. Assistant Trade Representative for Europe and Middle East Affairs, said he believed Trump's letter to the EU was to push the EU to reach a better agreement. Trump had previously threatened to impose 50% tariffs on the EU in May, a move that appeared to speed up the negotiation process. However, Marani said the letter could encourage those within the EU who want revenge, who believe the United States is not serious about reaching a deal. These people will feel that their opinions are reasonable, he said. (Jin Shi)
