(ANSA) - BELGRADE, JUN 22 - Serbia, Albania, and North Macedonia will attend a major summit on EU integration in Brussels tomorrow, despite earlier threats to skip it out of frustration with the pace of their EU membership progress. According to a statement released by the Serbian presidential cabinet on Wednesday, Serbian President Aleksandar Vucic and the Prime Ministers of Albania and North Macedonia, Edi Rama and Dimitar Kovacevski, have chosen to attend the EU-Balkans summit.
