used both for domestic consumption and export; oil used for domestic consumption; and significant reserves of copper, lead, zinc, tungsten, and uranium. Inefficiency in energy use is generally high, because the low controlled prices do not stimulate consumers to conserve energy. Uzbekistan is a partner country of the EU INOGATE energy programme, which has four key topics: enhancing energy security, convergence of member state energy markets on the basis of EU internal energy market principles, supporting sustainable energy development, and attracting investment for energy projects of common and regional interest. The country's larget steel manufacturer is Uzmetkombinat. The company is planning an IPO in 2023. External trade and investment Since the 2017 liberalisation of the foreign exchange market, Uzbekistan has seen rapid growth in exports. Traditional export products such as gas and cotton are now kept domestically for processing. They have been replaced by a vast growth in exports in areas such as fruit, textiles and home appliances. In recent years textile export has doubled in revenue to almost US$3bn worth of goods exports. Home appliance manufacturer Artel has seen exports rise from $5.6m in 2017, to around $100m in 2021. Before this, the system of multiple exchange rates combined with the highly regulated trade regime caused both imports and exports to drop each from about US$4.5 billion in 1996 to less than US$3 billion in 2002. The success of stabilization and currency liberalization in 2003 has led to significant increases in exports and imports in recent years, although imports have increased much less rapidly: while exports had more than doubled to US$15.5 by 2011, imports had risen to US$6.5 billion only, reflecting the impact of the government's import substitution policies designed to maintain hard currency reserves. Draconian tariffs, sporadic border closures, and border crossing "fees" have a negative effect on legal imports of both consumer products and capital equipment.
