East Turkistan, which has rich natural resources, is home to 78% of the mineral diversity in all of China. So much so that a total of 138 different mines have been identified in East Turkistan and chromium, salt, iron, stone cotton, manganese, copper, silicon, lead, diamond, gold, silver, and coal are obtained from actively operated mines. These mines in East Turkistan correspond to 85% of all mines in China. Since most of the mined minerals are not found in China, they are transferred to the interior of China.
