After several years of double-digit economic growth, Armenia faced a severe economic recession with GDP declining more than 14% in 2009, despite large loans from multilateral institutions. Sharp declines in the construction sector and workers' remittances, particularly from Russia, were the main reasons for the downturn. The economy began to recover in 2010 with nearly 5% growth. Under the old Soviet central planning system, Armenia developed a modern industrial sector, supplying machine tools, textiles, and other manufactured goods to sister republics, in exchange for raw materials and energy. Armenia has since switched to small-scale agriculture and away from the large agroindustrial complexes of the Soviet era. Armenia has managed to reduce poverty, slash inflation, stabilize its currency, and privatize most small- and medium-sized enterprises. Since the breakup of the Soviet Union in 1991, Armenia had made progress in implementing some economic reforms, including privatization, price reforms, and prudent fiscal policies, but geographic isolation, a narrow export base, and pervasive monopolies in important business sectors have made Armenia particularly vulnerable to the sharp deterioration in the global economy and the economic downturn in Russia. The conflict with Azerbaijan over the ethnic Armenian-dominated region of Nagorno-Karabakh contributed to a severe economic decline in the early 1990s and Armenia's borders with Turkey remain closed. Armenia is particularly dependent on Russian commercial and governmental support and most key Armenian infrastructure is Russian-owned and/or managed, especially in the energy sector. The electricity distribution system was privatized in 2002 and bought by Russia's RAO-UES in 2005. Construction of a pipeline to deliver natural gas from Iran to Armenia was completed in December 2008, and gas deliveries are slated to expand due to the April 2010 completion of the Yerevan Thermal Power Plant. Armenia has some mineral deposits (copper, gold, bauxite). Pig iron, unwrought copper, and other nonferrous metals are Armenia's highest valued exports. Armenia's severe trade imbalance has been offset somewhat by international aid, remittances from Armenians working abroad, and foreign direct investment. Armenia joined the WTO in January 2003. The government made some improvements in tax and customs administration in recent years, but anti-corruption measures have been ineffective and the current economic downturn has led to a sharp drop in tax revenue and forced the government to accept large loan packages from Russia, the IMF, and other international financial institutions. Armenia will need to pursue additional economic reforms in order to regain economic growth and improve economic competitiveness and employment opportunities, especially given its economic isolation from two of its nearest neighbors, Turkey and Azerbaijan.
