In Rocky IV, in which country does Rocky train before fighting Ivan Drago?

In Rocky IV, Rocky trains in the Soviet Union before fighting Ivan Drago.

Rocky travels to the Soviet Union after accepting a Christmas Day bout against Drago. The film contrasts Rocky’s old-fashioned outdoor training with Drago’s technologically assisted preparation. Rocky runs through snow, chops wood, lifts improvised equipment, and trains in a remote rural setting.

The location reflects the Cold War setting of the story. Rocky is an American boxer facing a Soviet representative, and the match becomes a symbolic confrontation as well as a sporting event. The final fight takes place in Moscow.

The film was released while the Soviet Union still existed. It should not be described as taking place in modern Russia, even though much of the relevant territory is now within Russia. Rocky IV’s fictional training location is identified with the Soviet Union.
