Although dominated by state-owned stores and distribution channels under the Soviet economy, retailing has seen a marked shift toward private business. Since 1992, thousands of small businesses have been privatized or leased to worker collectives, with the most progress in retail trade, consumer services, public catering, and local industry. However, the shift from state-control to a free market economy continues to move at a very slow pace. Urban markets provide an important outlet for the sale of vegetables and other foodstuffs. Government restrictions on trade and foreign investment have hindered the economy. Black market trade is still available.
