BERLIN: German Foreign Minister Johann Wadephul emphasized the importance of transatlantic relations on Sunday as he left for a trip to Washington. “Never before has it been so crucial to invest in the transatlantic partnership in order to remain capable of shaping the world order,” Wadephul said in Berlin before his departure. He said he would address what he called “differences of opinions” between Germany and the United States during a meeting on Monday with US Secretary of State Marco Rubio.
