BERLIN — Friedrich Merz plunged straight into international crises on his first full day as Germany's new chancellor Wednesday, presenting a united front with France against U.S. President Donald Trump's trade war, demanding more aid for Gaza and announcing he soon would visit Ukraine.
Merz and French President Emmanuel Macron — firm believers in the European Union and leaders of the continent's largest economies — used their first meeting since the German leader's appointment Tuesday to show unity on Ukraine and other issues causing alarm in Europe. They vowed to strengthen the continent's security and increase defense spending.
The tandem of Germany and France has long underpinned the 27-nation bloc, but lost some of its vigor in recent months as leaders in both countries wrestled with domestic issues.
In a joint news conference, Merz acknowledged that Europe still needs the U.S. for peace in Ukraine. ''It is our firm conviction that we cannot end this war in Ukraine without further political and military engagement by the United States of America,'' he said. ''The Europeans cannot replace this at present.''
Both Trump and Russian President Vladimir Putin have been exerting pressure on the EU, forcing it to rethink its own security. It was not clear when Merz would visit Ukraine.
Macron said that France and Germany will ''accelerate'' defense cooperation, including jointly developing new defense technologies ''necessary for the wars of tomorrow.'' He listed working together on tanks, long-range missiles and combat aircraft. He also said that the countries would start regular meetings of a French-German defense council.
Merz also visited Poland on Wednesday and addressed his new government's plans to station more police at Germany's border to curb illegal migration and even turn away some asylum-seekers.
''If we, everybody together in the European Union, give the signal to those who are setting out for Europe without valid opportunities for entry, if we give this signal especially to the traffickers, that these routes are going to get a lot more difficult and that we are going to close them, then that is a joint and good signal,'' Merz said during a joint news conference with Polish Prime Minister Donald Tusk.
