(ANSA) - BELGRADE, DEC 1 - In Sarajevo, the international diplomatic activity aimed at easing the growing tensions linked to the political and institutional crisis in Bosnia-Herzegovina.

The envoys of the US and EU, Matthew Palmer and Angelina Eichhorst, local media report, are planning a third round of talks with the leaders of the main political forces.

These forces represent the three ethnicities of the Balkan country, Bosnian Muslim, Serbian Orthodox, Croatian Catholic, as defined by the Dayton Accords that ended the war in 1995. The focus is on reforming the electoral law, which continues to discriminate against representatives of minorities in the two entities that make up the country, the Republika Srpska, with a Serb majority, and the Muslim-Croat Federation.

Also arriving in Bosnia-Herzegovina today is Michael Roth, German Minister for European Affairs. On the eve of his visit, he called the situation in the Balkan country "frustrating" and a "threat to peace and stability throughout Europe." Roth will meet with the Bosnian foreign minister, Bisera Turkovic, and the international High Representative, Christian Schmidt. The crisis in Bosnia and Herzegovina depends on the growing autonomy aspirations of Bosnian Serb leader Milorad Dodik, with fears in the international community of a possible secession of Republika Srpska from the Bosnian state.
