Many Russians credit Putin for reviving Russia's fortunes. Former Soviet Union leader Mikhail Gorbachev, while acknowledging the flawed democratic procedures and restrictions on media freedom during the Putin presidency, said that Putin had pulled Russia out of chaos at the end of the Yeltsin years, and that Russians "must remember that Putin saved Russia from the beginning of a collapse." In 2015, opposition politician Boris Nemtsov said that Putin was turning Russia into a "raw materials colony" of China. Chechen Republic head and Putin supporter, Ramzan Kadyrov, states that Putin saved both the Chechen people and Russia.
