China has on Wednesday extended the anti-dumping duty on potato starch from the European Union for another five years, the Ministry of Commerce said on its website.

In February 2007, the ministry imposed anti-dumping duties ranging from 18 to 35 percent on EU potato starch, which is used in the food processing, medicine and petrochemical industries. The duty was revised to 12.6 to 56.7 percent in April 2011.
