BERLIN—France and Germany have agreed to deepen a 1963 treaty of post-war reconciliation, in a bid to show that the European Union’s main axis remains strong and to counter growing euroskeptic nationalism among some other members.
The extension to the Elysee Treaty, approved by the German and French cabinets, will be signed by Chancellor Angela Merkel and French President Emmanuel Macron in the German border city of Aachen, a historical symbol of European concord, on Jan. 22.
