BRUSSELS, Jan 17 (Reuters) - European Union leaders on Saturday warned of a "dangerous downward spiral" over U.S. President Donald Trump's vow to implement increasing tariffs on European allies until the U.S. is allowed to buy Greenland.
"Tariffs would undermine transatlantic relations and risk a dangerous downward spiral. Europe will remain united, coordinated, and committed to upholding its sovereignty," European Commission President Ursula von der Leyen and EU Council President Antonio Costa said in posts on X.
