“European Commission President Jean-Claude Juncker on Wednesday called on Kosovo to ratify a border demarcation deal with Montenegro and improve ties with Serbia.

Juncker was near the end of a tour of Western Balkan countries which hope to join the European Union. The EU has drafted a new expansion strategy that envisages Serbia and Montenegro could be the next to join the bloc in 2025.

It was the first visit to Kosovo by an EU Commission chief and he was accompanied by EU foreign policy chief Federica Mogherini and Enlargement Commissioner Johannes Hahn.

The EU says the border deal is a precondition for Kosovo’s citizens to travel freely within its visa-free travel zone known as Schengen.

‘The most fundamental issue is the ratification of the border demarcation with Montenegro,’ Juncker said. ‘That is a fundamental issue, an important one because it is linked with the visa liberalization.'” (ABC News)
