Trump has vowed to impose tariffs on the EU or 10 percent on China

U.S. President Donald Trump has vowed to impose tariffs on the European Union and said discussions are under way to impose a 10 percent tariff on imports from China starting Feb. 1.

"We're talking about putting a 10 percent tariff on China because they're shipping fentanyl into Mexico and Canada," Trump told reporters at the White House on Tuesday, Reuters reported.

​ "We don't talk much about tariffs, other than he knows my position," Trump said Tuesday in response to a question about their conversation.

He said he imposed high tariffs on China in his first term. "I've made hundreds of billions of dollars. Before I was president, China had never paid a dime to the United States."

Trump also said that the trade imbalance between the European Union and other countries and the United States is troubling.

"The EU has treated us very, very badly, so we're going to slap them with tariffs." That's the only way you're going to get justice."
