The prospect of EU membership has been a powerful driver of reform in the Balkans since former Yugoslavia disintegrated into war in the early 1990s, and the EU's executive arm, the European Commission, recommended last month that the two be invited to open negotiations.
At a summit in Brussels next week, EU leaders will discuss the candidacies of Albania and North Macedonia, but the chairman of their meeting — European Council President Donald Tusk — signaled Wednesday that not all countries want them to start negotiations right now.
"Over the last two years, your country has delivered all the right political signals that the EU was expecting from the candidates," Tusk said, standing alongside North Macedonia President Stevo Pendarovski. "You have done everything that was expected of you."
"But I want to be honest with you: not all member states are prepared to make the decision on opening negotiations in the coming days," Tusk added. The continued expansion of the 28-nation EU has complicated decision-making, and a kind of enlargement fatigue set in after 10 countries joined in 2004. Upon taking up his post as European Commission president in 2014, Jean-Claude Juncker said no countries would join during his term, which ends on Oct. 31.
EU foreign policy chief Federica Mogherini warned last month that Europe is "at a crossroads" when it comes to enlargement in the Balkans. "We always say that it is a merit-based process, so when merit is assessed as positive it needs to be acknowledged," she said.
"Failure to recognize and respond to objective progress would damage the European Union's credibility," Mogherini said, adding that it could also "undermine stability and seriously discourage further reforms."
Her warning came a day after Serbia put its troops on full alert when armed Kosovo police fired tear gas and arrested about two dozen people in Serb-dominated northern Kosovo in what they called an operation against organized crime.
North Macedonia was granted membership candidate status under the name Macedonia in 2005 but accession talks never began, mostly because of the dispute with Greece over its name. The two neighbors struck a deal last year and North Macedonia was born, paving the way for the country to join NATO and, eventually, the EU.
