​U.S. chicken exports to China have fallen by 90 percent over the past four years, costing sellers an estimated $1 billion, after China imposed high anti-dumping duties on the meat. A WTO panel ruled in favor of a U.S. complaint on Aug. 2 and the WTO adopted the decision on Wednesday without an appeal from China.

U.S. Trade Representative Michael Froman said that in the wake of the ruling, China should revise its trade rules. Agriculture Secretary Tom Vilsack said in a statement, “we look forward to seeing China’s market for broiler products restored for U.S. farmers and chicken producers.”

The United States and China, the world’s two largest economies, are engaged in a number of trade disputes, including those involving Chinese tires and U.S.-made cars.

In late August, the Agriculture Department cleared China to ship cooked chicken to the United States if the raw meat originated in Canada, Chile or the United States. USDA’s food safety chief said on Wednesday that China has yet to act on the approval. Congress blocked such imports from 2008 to 2010. (Reuters)
