BRUSSELS – Serbia will open two negotiation chapters at Tuesday’s intergovernmental conference (IGC) on its EU accession – Chapters 5 (public procurement) and 25 (science and research), with the EU-Serbia Association and Stabilisation Council to also hold a regular meeting.

The IGC will be attended by Serbian Minister for European Integration Jadranka Joksimovic, but not PM Aleksandar Vucic, who decided late Monday to leave Brussels after the EU had failed to reach an agreement with Croatia on lifting Zagreb’s veto on also opening Chapter 26.

“I made no secret of my dissatisfaction and disappointment with the conduct of individual member states, in particular Croatia,” Vucic said after a meeting with EU foreign policy and security chief Federica Mogherini.

The Serbian government has announced Vucic would hold a press conference on the issue at 6 pm Tuesday.
