QUES: Tajikistan's economy grew substantially after the war. The GDP of Tajikistan expanded at an average rate of 9.6% over the period of 2000–2007 according to the World Bank data. This improved Tajikistan's position among other Central Asian countries (namely Turkmenistan and Uzbekistan), which seem to have degraded economically ever since. The primary sources of income in Tajikistan are aluminium production, cotton growing and remittances from migrant workers. Cotton accounts for 60% of agricultural output, supporting 75% of the rural population, and using 45% of irrigated arable land. The aluminium industry is represented by the state-owned Tajik Aluminum Company – the biggest aluminium plant in Central Asia and one of the biggest in the world.
