The ministers are among 48 delegations gathered in Sarajevo Wednesday for a joint European Union-Western Balkans conference, the Serbian news agency B92 reports.
Integration of the Western Balkans into the EU is among the many issues the conference will discuss.
Serbian Foreign Minister Vuk Jeremic has said he expects the conference to result in a clear signal that the process of European integration will not be halted.
"It would really be a big mistake if this would not be followed not only by a continuation but also by an acceleration of the process of European integrations," Jeremic said.
Jeremic said the region has made major progress in the areas of political relations and reconciliation.
The final declaration of the conference will be prepared by EU officials without the participation of Western Balkan ministers.
