European Union foreign policy chief Josep Borrell said that Serbian President Aleksandar Vucic and Kosovo Prime Minister Albin Kurti did not reach a solution at a crisis meeting in the Belgian capital, Brussels, on Thursday.

"Unfortunately, we have not yet reached an agreement, but it is not the end, the two leaders agreed that the process should continue and discussions would resume in the coming days," Borrell told reporters in Brussels after hours of talks.

After the talks facilitated by the European Union, Borrell said that there was still time until 1 September, "and I am not giving up." He told the two leaders that after the outbreak of war in Europe, now was the moment to achieve peace and stability, not to inflame the differences that have existed since long time.

For his part, the Serbian president described today's meetings at the European Union headquarters in the Belgian capital, Brussels, as difficult, and continued in a video clip on social media, "I cannot say that the talks ended successfully, but I will refrain from other comments because I hope that a miracle will happen and we will reach an agreement."

tense then calm down

Tensions erupted between Serbia and Kosovo this month when Pristina said it would require Serbs living in the north, who are supported by Belgrade and do not recognize Kosovo's institutions, to start using their car license plates.

The situation calmed after Kurti, under pressure from the United States and the European Union, agreed to postpone new rules on license plates until Sept. 1, while NATO peacekeepers oversaw the removal of roadblocks erected by Serbs.

Kosovo, where the majority of the population is Albanian, separated from Serbia in 1999, and declared its independence from it in 2008, but Belgrade still considers it part of its territory, and supports the Serb minority in it.
