The European Union’s top trade negotiator has signaled the bloc will continue trying to reach a deal with the U.S. after President Donald Trump threatened a 30% tariff on goods from the bloc and Mexico over the weekend.

President Donald Trump threatened a 35% tariff on some Canadian goods and raised the prospect of increasing levies on most other countries, ramping up his trade rhetoric in comments that weighed on stocks and boosted the US dollar.

The president revived his discredited claims about fentanyl entering the U.S. from Canada to justify his latest proposed rate of 35 percent.
