(ANSA) - BELGRADE, JUN 5 - "With Emmanuel Macron, we presented a concrete proposal for how to proceed and make enlargement possible, particularly in some Western Balkan countries. The EU must demonstrate its capability and willingness to expand." This was stated by German Chancellor Friedrich Merz upon arriving at the EU-Western Balkans Summit in Tivat, Montenegro. "There are still many questions we need to address, and we must do so together. But above all, this part of Europe must belong to the EU in the future. If we haven't welcomed new members for 13 years," it means "that the shortcomings were not only those of the candidate countries, but also of the EU," Merz emphasized. (ANSA).
