Labor Minister Rasim Ljajic, who heads Serbia's Hague Cooperation Council, told B92 in Belgrade the government will mount "a diplomatic offensive in all international forums in order to bring this case to its conclusion."
Ljajic was going to Strasbourg, France, Monday to meet with the Council of Europe.
The council's investigator, Dick Marty, presented a report last week. The report names Kosovo Prime Minister Hashim Thaci as ringleader of a gang of organ traffickers in the Kosovo Liberation Army. Most of their victims are believed to have been Kosovo Serb civilians kidnapped in 1999 and 2000.
Ljajic said he will tell the council Serbia expects action on the report.
"Serbia is asking for nothing else than for the truth to be established about all accusations and, naturally, for justice to be done, because that is a condition for reconciliation in the region," he said.
Marty travels Monday to Moscow, where he will present his report to Russian officials.
Foreign Minister Sergei Lavrov said last week the accusations, if true, constitute crimes against humanity.
