President Donald Trump said he remains willing to negotiate with the European Union and other trading partners before a planned 30% tariff on most EU goods takes effect on Aug. 1. Speaking at the White House and in subsequent comments to NBC News, Trump said EU officials will travel to Washington for talks and signaled he could also speak with Canadian Prime Minister Mark Carney about separate tariff issues. The administration last weekend sent formal letters warning that the 30% levy would be imposed unless new agreements are reached, extending by three weeks an earlier deadline. White House economic adviser Kevin Hassett said discussions are also under way with Canada and Mexico, which face duties of up to 35% and 30%, respectively. Brussels has prepared a two-tier response. An existing list covering €21 billion ($24.5 billion) of U.S. products is ready for activation, and officials have drafted a second list worth about $84 billion that targets aircraft, automobiles, bourbon and other goods. EU Trade Chief Maros Sefcovic called the U.S. measure “effectively prohibitive” and warned the bloc will take “well-considered and proportionate” countermeasures if talks fail. European leaders and industry groups said the threatened duties could disrupt trans-Atlantic supply chains and hit exporters, with German Chancellor Friedrich Merz warning the move would “hit the German export industry to the core.” European auto and beverage shares slipped after the latest tariff salvo, while U.S. markets were little changed.
