French President Emmanuel Macron and Chancellor Angela Merkel on Tuesday signed a new friendship treaty that is designed to deepen the Franco-German friendship, bring ties to a "new level" and improve the lives of citizens in both countries, DW reported.

The treaty was signed in the German city of Aachen, as France and Germany marked the 56th anniversary of the Elysee Treaty.

The idea isn't new. Paris, in particular, has regularly suggested renewing the treaty in the decades since it was first signed, despite the fact that amendments have been added over the years.

The Treaty of Aachen will be the "foundation of cooperation between our countries," said Merkel before the signing the new friendship pact.
