President Donald Trump has announced he’s levying tariffs of 30% against the European Union and Mexico starting Aug. 1.

President Trump is reportedly pushing for higher blanket tariffs on imports from the European Union, throwing a wrench in negotiations ahead of an Aug. 1 deadline for sweeping duties to take effect. The Financial Times reported that Trump wants a minimum of a 15% to 20% tariff on EU goods as part of any deal.

Stocks were mixed in early trading on Monday after President Donald Trump over the weekend issued 30% tariffs on the European Union and Mexico, rekindling tensions with two of the largest U.S. trade partners and threatening to raise consumer prices.
