Calls for the secession of portions of Bosnia or the weakening of the Balkan state are “irresponsible and unacceptable,” a German official said, mentioning Bosnian Serb politician Milorad Dodik as a particular perpetrator.

The situation in Bosnia, where Dodik, the Bosnian Serb member of the three-member presidency, is pressing for the finely balanced federation to be further decentralized, will be examined by European Union foreign ministers on Monday, according to Foreign Ministry spokesperson Andrea Sasse.

“Calls for secession and steps to weaken the whole state, especially from Republika Srpska and from Milorad Dodik, the Serbian member of the three-member presidency are totally irresponsible and unacceptable,” Sasse said.

“This endangers the stability not just of Bosnia-Herzegovina but also that of the whole region,” she told a regular government news conference.

Bosnia was structured into a multi-ethnic federation as part of the resolution of Yugoslavia’s break-up into seven successor states in a series of wars that claimed over 100,000 lives and lasted for much of the 1990s.
