On August 21, US President Donald Trump said that he would put a 25% tariff on cars from the European Union.
In July, President of the European Commission Jean-Claude Juncker and Trump held a meeting to discuss trade relations between the two sides agreeing, among other things, to avoid any new tariffs while negotiating future arrangements for trans-Atlantic trade.
Trade relations between the two sides soured in June, after Trump imposed tariffs on steel and aluminum imported from the European Union, Canada and Mexico. The European Union retaliated by levying its own tariffs on over $3.2 billion worth of the US imports, saying that the US tariffs targeted over $7.4 billion worth of the EU exports.
