The chairman of the presidency of Bosnia and Herzegovina is pledging to spare no effort to preserve the country's democracy and multi-ethnic diversity as it seeks to enter the European Union.

The pledge by Dragan Covic comes as Serb authorities are trying to challenge the authority of the national court over the Serb half of the country, a move the U.S. and EU say would threaten Bosnia's sovereignty and security.

The peace agreement that ended Bosnia's civil war two decades ago split the country into two semi-autonomous mini-states along ethnic lines, one shared by Muslims and Croats and the other for Serbs.

Covic told the U.N. General Assembly's ministerial that Bosnia is intensively working on reforms to improve social and economic conditions and the rule of law.
