"Russia may demand new negotiations as much as it likes, but neither we nor other parties involved are prepared for that," Agim Ceku said.
He said he was convinced that Kosovo would become an independent state before the end of May, when the UN Security Council adopts a resolution.
"Some permanent members of the Security Council may abstain from the vote, but in the last few days of May, Kosovo will acquire independence," he said.
Russia's foreign minister said earlier Friday efforts to push through a UN plan granting Kosovo supervised independence is an attempt to impose a one-sided solution on the region.
The plan proposed by Martti Ahtisaari proposes internationally supervised sovereignty for Kosovo. As a veto-wielding UN Security Council member and long-time Serb ally, Russia is opposed to the proposal.
Some Western countries have said violence would be inevitable if Kosovo failed to secure independence. But Sergei Lavrov said it was nothing but "blackmail."
"The view that partitioning a sovereign state can bring stability to the region is totally illogical," he said.
Lavrov reiterated his appeal for direct negotiations between Kosovo and Serbia, and for a solution that would satisfy both Kosovar and Serbian authorities.
During the first round of UN consultations on the Ahtisaari plan April 3, only four out of 15 permanent member-states at the UN Security Council voted for Kosovo's sovereignty.
As an alternative to the Ahtisaari plan, Moscow proposed sending a UN mission to Kosovo and Belgrade before continuing talks on Kosovo's status. The UN Security Council backed Russia's initiative April 13, and the UN mission is expected to visit Belgrade April 25-26 and Pristina April 27-28, the Serbian Tanjug news agency has said, citing UN diplomatic sources.
The Serbian government reacted strongly Tuesday to recent comments by a U.S. administration official concerning independence for Kosovo.
Nicholas Burns, undersecretary of state for political affairs, said Monday that if the UN Security Council does not adopt a new resolution on Kosovo granting the province independence, the U.S. would unilaterally support a declaration by Kosovo's Albanian authorities on separation from Serbia.
"The U.S. position is in favor of full independence for Kosovo, which was enunciated by Nicholas Burns, runs counter to UN Security Council Resolution 1244, enshrining Serbia's territorial integrity," the Serbian government said in a statement.
It said any unilateral recognition of Kosovo's independence is a gross violation of the UN Charter.
Serbia is strongly opposed to independence for the province, which is dominated by ethnic Albanians, but the United States and the European Union have expressed support for sovereignty.
Kosovo, which has a population of two million, has been a UN protectorate since NATO's 78-day bombing campaign against the former Yugoslavia ended a war between Serb forces and Albanian separatists in 1999.
