FILE- In this May 18, 2008, file photo, Russian billionaire Alisher Usmanov stands near pieces from the art collection of late cellist Mstislav Rostropovich and his wife Galina Vishnevskaya in the Konstantin Palace outside St. Petersburg, Russia. An ethnic Uzbek, Usmanov is perhaps the most successful native of ex-Soviet Central Asia to make a fortune in Russia. The old Moscow is rapidly giving way to a multi-ethnic city where Muslims from Central Asia are the fastest growing sector of the population. (AP Photo/Dmitry Lovetsky, File)
