An exchange rate of 100 to 110 rubles per US dollar is "reasonable" as it balances the interests of the state and exporters, Vladimir Potanin, Russia's richest man, said on Saturday.

The range "is something quite reasonable in economic terms, something that the country can live with," Potanin said in an interview with RBC TV. "This is a kind of balance between budgetary interests and the interests of exporters."
