Serbian Prime Minister Vojislav Kostunica says preserving Serb rights in Bosnia-Herzegovina and Kosovo are the main goals of his administration.
The Serbian leader, in a statement, accused international officials of efforts to undermine the 1995 Dayton peace accord that halted the Bosnian conflict and United Nations resolutions on the future of Kosovo.
He was referring to efforts by the top international mediator in Bosnia, Miroslav Lajcak, to streamline the work of the country's central institutions. Bosnian Serb Prime Minister Milorad Dodik has challenged the mediator's order and threatened to withdraw all Serb representatives from Bosnia's central government bodies.
On Kosovo Mr. Kostunica again reaffirmed his country's opposition to the plan U.N. mediator Martti Ahtisaari has proposed for supervised independence for Serbia's breakaway province.
Kosovo's ethnic Albanian majority seeks independence, a position both Serbia and its ally Russia have rejected.
Representatives of the two sides are engaged in talks on the future of the province.
The United Nations has administered Kosovo since 1999, when NATO airstrikes drove Serbian and Yugoslav security forces from the province.
