Putin made the statement following today's talks with his Belarusian counterpart, Alexander Lukashenko.
Lukashenko, who has been dubbed "Europe's last dictator" in the West, has led the 10-million nation with an iron hand for nearly two decades, tolerating no dissent. He has kept most assets in state hands and relies on subsidies from Russia to shore up the economy.
Russia and Belarus have had close economic, political and military ties. Russia has several military facilities in Belarus, and the two nations operate a joint air defense system.
