Senior members of the European Union’s executive arm and US officials spoke on Friday to explore ways to move forward after US President Donald Trump’s metals tariffs prompted a trade war.

A full-scale global trade war would hurt the United States in particular and could re-energise Europe's push towards unity, European Central Bank President Christine Lagarde said on Friday. The U.S. has imposed a raft of tariffs on friends and foes alike and threatened even more measures,

President Trump said he would impose a 200% tariff on U.S. imports of wine, Champagne and other alcoholic beverages from the bloc.
