Since independence, the economy of Uzbekistan continues to exist as a Soviet-style command economy with slow transformation to market economy. The progress of governmental economic policy reforms has been cautious, but cumulatively Uzbekistan has shown respectable achievements. Its restrictive trade regime and generally interventionist policies continue to have a negative effect on the economy. Substantial structural reform is needed, particularly in these areas: improving the investment climate for foreign investors, strengthening the banking system, and freeing the agricultural sector from state control. Remaining restrictions on currency conversion capacity and other government measures to control economic activity, including the implementation of severe import restrictions and sporadic closures of Uzbekistan's borders with neighboring Kazakhstan, Kyrgyzstan, and Tajikistan have led international lending organizations to suspend or scale back credits.
