China Sunday started anti-dumping and anti-subsidy investigations into chicken products imported from the United States, the Ministry of Commerce said.

The ministry had carefully evaluated applications from domestic chicken producers, and found grounds for investigation. It will make a final judge based on law and facts, it said.

The United States is the largest chicken products exporter to China, comprising 90 percent of the 407,000 tons of chicken China imported in the first half of 2009.
