"We hope the United States implements the WTO ruling as soon as possible for stable and sound development of Sino-U.S. economic and trade relations," the official Xinhua news agency reported, quoting a Ministry of Commerce spokesman.
The WTO finding stems from anti-dumping and countervailing duties imposed by the United States on Chinese exports of steel pipes, woven sacks and some off-road tires.
A WTO panel last year supported the U.S. action but a WTO appeals panel earlier this month handed down a ruling favorable to China. The new ruling was seen as severely restricting the rights of importing countries to take punitive actions.
"The (winning of the) case is a great victory for China in using WTO rules to protect the country's rights and will greatly boost WTO members' confidence in multilateral rules," the ministry spokesman said.
