Russian President Vladimir Putin agreed early last week to provide humanitarian aid to crisis-hit Serb areas in Kosovo in line with a request from Serbia's government.
"Flights with humanitarian assistance have also been scheduled for April 4 and 8," Alyona Kudryavtseva said.
The first batch contains rice, sugar, canned foods, as well as medicine and medical equipment.
Kosovo, with a 90% ethnic Albanian majority, has been recognized as a sovereign state by the United States, most European Union members, and several other countries since it proclaimed independence on February 17. Russia and China have sided with Belgrade, which says Kosovo will always remain a part of its territory.
Two weeks ago violence broke out in the north of Kosovo as rioters attacked UN peacekeepers following the arrests of ethnic Serbs who had seized a UN court building in protest against the province's secession. A Ukrainian peacekeeper was killed and dozens of people, both Serbs and UN personnel, were injured.
