EU's lead negotiator with the US warns that Trump's threat to impose 30% tariffs on European goods would almost prohibit transatlantic trade, worth €4.4bn a day.
The EU was close to finalizing a deal with the US before Trump's announcement, leading to disappointment and uncertainty.
In response, the EU postponed retaliatory counter-tariffs and is considering additional measures targeting €72bn of US imports.
European nations hold varying views on responding to Trump's tariffs, with some advocating for de-escalation and others urging preparation for potential trade conflicts.
