The president said he would impose the levies if the European Union does not walk back plans to place retaliatory tariffs on whiskey and other U.S. products.

President Donald Trump on Thursday threatened to impose a massive tariff on European alcohol in response to the European Union’s retaliation against his steel and aluminum tariffs – a tit-for-tat escalation of a trade war that could easily get out of hand.

Earlier today, Trump shared on social media that he would put a 200% tariff on European alcohol, in response to the EU's retaliatory tariffs on American whiskey. Trump has also directly touched upon Canada during his Oval Office meeting with Nato's Secretary-General.
