”We cannot get our product in. It’s very, very tough. And yet they send their product to us — no taxes, very little taxes. It’s very unfair."

Trump over the summer slammed the EU as "very protectionist." He also said in the same tweet that he was working on a "major" trade deal with the United Kingdom, which voted to leave the EU in 2016.

“They’re not the only one, by the way. I could name many countries and places that do. But the European Union has been very, very unfair to the United States. And I think it will turn out to be very much to their detriment," Trump said on Sunday.

The president has frequently accused other countries of putting the U.S. at a trade disadvantage. He announced last year he would withdraw from the Trans-Pacific Partnership (TPP), a multilateral trade agreement with Pacific Rim countries, and has threatened to do the same with the North American Free Trade Agreement.

Trump suggested last week that he would consider re-entering TPP if a "substantially better deal" were made.
