U.S. trade partners reacted Friday to President Donald Trump's executive order that would introduce new tariffs on many of them in seven days, as the global economy and alliances face another test from the president's trade agenda.

On Thursday, Donald Trump announced sweeping new tariffs against U.S. trading partners that will go into effect next week. The announcement came on the same day that an appeals court grappled with the question of whether Trump’s tariffs are even legal.
