Out of former Soviet Union republics Uzbekistan continued and expanded the program of child labour on industrial scale to increase profits on the main source of Islam Karimov's income, cotton harvesting. In September, when school normally starts, the classes are suspended and children are sent to cotton fields for work, where they are assigned daily quotas of 20 to 60 kg of raw cotton they have to collect. This process is repeated in spring, when collected cotton needs to be hoed and weeded. In 2006 it is estimated that 2.7 million children were forced to work this way.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What was the main source of income for Islam Karimov?
cotton harvesting
