Russia has undergone significant changes since the collapse of the Soviet Union, moving from a globally-isolated, centrally-planned economy towards a more market-based and globally-integrated economy, but stalling as a partially reformed, statist economy with a high concentration of wealth in officials’ hands. Economic reforms in the 1990s privatized most industry, with notable exceptions in the energy and defense-related sectors. The protection of property rights is still weak and the private sector remains subject to heavy state interference. Russia is one of the world’s leading producers of oil and natural gas and is also a top exporter of metals such as steel and primary aluminum. Russia’s manufacturing sector is generally uncompetitive on world markets and is geared toward domestic consumption.
