The EU says in statement "there is serious concern about the current political deadlock" in the Balkan country.
Friday's statement says Swedish Foreign Minister Carl Bildt and U.S. Deputy Secretary of State Jim Steinberg decided to convene the meeting in Sarajevo Oct. 9 "to stimulate political dialogue."
After an ethnic war between 1992 and 1995, Bosnia has been divided into a Serb Republic and a Bosniak-Croat Federation, linked by common institutions.
Officials in the Serb Republic generally seek more autonomy and oppose closer integration of institutions. Bosnian Serbs often feel solidarity with Serbia.
