The only acceptable tariff on European Union exports to the United States would be zero as the bloc is already facing a detrimental exchange rate, the head of Italy's business lobby said on Wednesday.

The European Union has finalized a second list of countermeasures to target U.S. goods worth $84 billion, including Boeing Co. aircraft, automobiles and bourbon, if it decides to retaliate against Donald Trump's tariff policy.

President Donald Trump has posted two new letters on his social media platform announcing tariffs on the European Union and Mexico.

President Donald Trump on Saturday threatened duties of 30% on products from Mexico and the European Union, two of America’s biggest trading partners, in an ongoing tariff campaign that’s upended global trade since he retook office in January.

The astonishing rebound in stocks since early April largely reflects investors' bet that U.S. President Donald Trump won't follow through on his tariff threats.

After European Union leaders said they would keep negotiating instead of immediately retaliating against President Trump’s latest threat, businesses remain unable to develop long-term plans.

U.S. stock futures fell Sunday, a day after President Donald Trump threatened to impose new 30% tariffs against imports from Mexico and the European Union.

U.S. President Donald Trump said he believed Britain would fight to defend the United States but suggested he could not say the same for the European Union, a factor in his decision not to sign a trade deal with the bloc.
