Nato member Greece asked for the bombing of Yugoslavia to stop but has continued to provide logistical assistance to the alliance.

It has also pledged aid to Serbia, a fellow Orthodox Christian ally. Greeks are worried they could face a mass influx of refugees from the Kosovo conflict, and the Greek government is also concerned that refugees in Albania could cause problems for the Greek minority in southern Albania.

Greece fears any change in borders created by the Kosovo crisis could undermine stability elsewhere in the Balkans. "There can be no peace or cooperation without the principle that borders will not change," Prime Minister Costas Simitis has said.
