Norway's Prime Minister Jonas Gahr Stoere and finance minister Jens Stoltenberg will meet with U.S. President Donald Trump in Washington on Thursday, the prime minister's office said.

The Italian Prime Minister, Giorgia Meloni, is the first European leader to travel to Washington since Trump introduced - then paused – 20% tariffs on the EU earlier this month.

U.S. President Donald Trump has agreed to an official visit to Rome and will consider also meeting representatives of the European Union while there, Italy's Prime Minister Giorgia Meloni said on Thursday in the Oval Office.
