"Tariffs are the greatest! Either a country which has treated the United States unfairly on Trade negotiates a fair deal, or it gets hit with Tariffs. It’s as simple as that — and everybody’s talking! Remember, we are the 'piggy bank' that’s being robbed. All will be Great!" Trump said in a Twitter statement.
The comments come ahead of a visit on Wednesday by European Commission President Jean-Claude Juncker to discuss trade with Trump at the White House.
Juncker said earlier on Tuesday that he has not prepared any offers for Trump regarding EU-US trade, and is simply looking to hold a dialogue.
EU-US trade relations have been tense since Trump imposed tariffs on steel and aluminum imports. The European Union imposed its own barriers on US goods after Trump lifted the EU's exemption from those tariffs.
