The risk of a US-European Union trade war is mounting as President Donald Trump and European Commission President Ursula von der Leyen meet Sunday in Scotland in a last-ditch effort to avoid steep tariffs.

The meeting comes just days before Trump’s August 1 deadline to impose a 30% tariff on EU imports if no agreement is reached. Trump is currently on a five-day visit to Scotland focused on golf and promoting his resorts. He was seen playing at his Turnberry course with sons Eric and Donald Jr. and their wives before the meeting.

Trump has expressed doubts over reaching a deal, saying there's “a 50-50 chance, maybe less” of an agreement. The EU delegation includes chief trade negotiator Maros Sefcovic and senior officials from the Commission’s trade and agriculture teams.

US Commerce Secretary Howard Lutnick told Fox News that the tariffs will go into effect as planned unless the EU offers a deal Trump finds acceptable. “No extensions, no more grace periods,” he said, but added Trump remains open to talks.

Without a deal, the EU has warned of retaliatory tariffs on a wide range of US goods, including beef, auto parts, beer, and Boeing aircraft.

On Monday, Trump is expected to meet UK Prime Minister Keir Starmer, also at Turnberry, amid ongoing US-UK trade discussions. Trump will travel to Aberdeen on Tuesday to open a new golf course.

Trump has also frozen trade talks with Cambodia and Thailand due to border violence, saying peace must come first.
