Kosovo Prime Minister Albin Kurti and Serbian President Aleksandar Vucic  attended EU-mediated talks in Brussels on Thursday aimed at alleviating renewed tensions between the estranged western Balkan neighbours.

The two men failed to reach a solution but agreed to further talks in the coming days, European Union foreign policy chief Josep Borrell said after the talks.

Ethnic Serbs in northern Kosovo blocked roads and erected barricades on July 31 in protest over Kosovo’s decision to oblige them to start using vehicle licence plates made in Pristina.

Both Kosovo and Serbia aim to join the European Union and in order to complete that process both parties need to resolve outstanding issues and build good neighbourly relations.
