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.

Italy's foreign minister warned that, while he hopes for successful negotiations, the EU will respond resolutely to Trump's latest tariff threat.

The EU says the U.S. is resisting efforts to strike a trade deal and warned of countermeasures if no agreement is reached with U.S. by Aug. 1.
