A new report by China's General Administration of Customs says trade in raw materials has continued to drop. Exports of Chinese raw materials have gone down every month for the past year-and-a-half, while imports have fallen for 20 months in a row. Trade in raw materials, has dropped nearly 7% since the start of the year.

According to the report, Chinese trade in raw materials sank to around 5 trillion yuan, or 760 billion U.S. dollars, but still accounted for about 30 percent of the global sector. One of the reasons behind the drop is China's improving domestic raw materials industry. Chinese enterprises are buying more raw materials from Chinese suppliers instead of from overseas.

The report also revealed strong industry growth in China's central and western regions. 15% percent of Chinese trade in raw materials occurs in the two regions. Up from 4 percent in 2010.
