China will make a serious assessment and reserve the right to appeal the World Trade Organization ruling on its anti-dumping duties on X-ray scanners imported from the European Union, the Ministry of Commerce said Wednesday.

The WTO's dispute settlement body on Tuesday issued a panel report largely in favor of the EU, which had filed a legal challenge to the body on China's anti-dumping duties on X-ray security equipment in July 2011.

China started to impose anti-dumping duties on the EU-produced X-ray security inspection equipment for five years on January 2011, at rates ranging from 33.5 percent to 71.8 percent.

The ministry also expressed support for the part of the ruling that backs China's requests.
