"Any state adhering to the ideals of democracy and humanism should abhor attempts to make heroes of Nazi accomplices," Vitaly Churkin said.
He condemned attempts by certain countries to declare the day of liberation from Nazism a day of mourning, to demolish monuments to fighters against Nazism and to erect monuments to Nazi supporters.
Churkin did not name any specific countries, but was clearly referring to Estonia, whose parliament is currently considering a bill that would pave the way for the demolition of Soviet monuments. Many Estonians regard Soviet soldiers as having been occupiers.
The controversial bill, which Estonian lawmakers passed in its first reading in November 2006, stemmed from a dispute over the Monument to a Soviet Liberator in central Tallinn, which authorities want removed, calling it socially divisive.
The plan has generated outspoken criticism not only in Russia, but in many other countries as well.
The UN General Assembly recently adopted a resolution condemning attempts to deny or diminish the scale of the Holocaust and urging the international community to fight racism.
"We have no right to forget the tragedy of the Holocaust if we want to prevent its repetition," said Churkin, whose country is a co-author of the resolution.
