According to EBRD transition indicators, Uzbekistan's investment climate remains among the least favorable in the CIS, with only Belarus and Turkmenistan ranking lower. The unfavorable investment climate has caused foreign investment inflows to dwindle to a trickle. It is believed that Uzbekistan has the lowest level of foreign direct investment per capita in the CIS. Since Uzbekistan's independence, U.S. firms have invested roughly $500 million in the country, but due to declining investor confidence, harassment, and currency convertibility problems, numerous international investors have left the country or are considering leaving. In 2005, the Central Bank has revoked the license of the nascent Biznes Bank citing unspecified violations of local currency exchange rules. The revocation prompted immediate bankruptcy procedures, under which clients' deposits stay arrested for two month. No interest was accrued during that two-month period. In 2006, the Government of Uzbekistan forced out Newmont Mining Corporation (at the time the largest U.S. investor) from its gold mining joint venture in the Muruntau gold mine. Newmont and the government resolved their dispute, but the action adversely affected Uzbekistan's image among foreign investors. The government attempted the same with British-owned Oxus Mining. Coscom, a U.S.-owned telecommunications company, involuntarily sold its stake in a joint venture to another foreign company. GM-DAT, a Korean subsidiary of GM, is the only known U.S. business to have entered Uzbekistan in over two years. It recently signed a joint-venture agreement with UzDaewooAuto to assemble Korean-manufactured cars for export and domestic sale. Other large U.S. investors in Uzbekistan include Case IH, manufacturing and servicing cotton harvesters and tractors; Coca-Cola, with bottling plants in Tashkent, Namangan, and Samarkand; Texaco, producing lubricants for sale in the Uzbek market; and Baker Hughes, in oil and gas development.
