However, manganese resources in China are very low grade and domestic supply can't satisfy demand, thus China's imports of manganese ore have been increasing year by year. In 2010, imported manganese ore accounted for 55% of China's total demand. In 2011, China imported 13 million tonnes (gross weight) manganese ore, up 12% from 2010.
