Europe’s exports to the U.S. plunged by a third in April as demand was squeezed by President Trump’s tariff increases, leading to a fall in factory output that suggests economic growth has slowed after a strong start to the year.

European Union exports to the U.S. dropped to 47.6 billion euros ($55.2 billion) from 71.5 billion euros a month earlier, statistics body Eurostat said Friday, marking a dramatic reversal from March’s record high, when American importers were stocking up ahead of Trump’s tariff announcement.
