The European Union has warned that its trade with the United States could be effectively wiped out if Washington makes good on its threat to slap a 30% tariff on goods imported from the bloc.

EU trade chief Maros Sefcovic will head to Washington on Wednesday for tariff talks, an EU spokesperson told Reuters, adding that he will meet U.S. Commerce Secretary Howard Lutnick and Trade Representative Jamieson Greer.

Unlike the European Union, the Japanese government has made no indication it plans to impose any kind of reciprocal tariff on the U.S., even if the U.S. does move forward with its planned 25% tariffs on all Japanese exports.

If a 30 percent tariff on Mexico goes into affect on August 1, a wide variety of foods will be more expensive, experts warn.
