A senior Chinese trade official said on Thursday that the recent anti-dumping and anti-subsidy investigations launched by the United States against Chinese goods violate rules of the World Trade Organization (WTO).

Addressing a press conference held by the State Council Information Office, Gao Hucheng, vice minister of commerce, said the U.S. investigations and the measures that it might take against Chinese goods will lead to double taxation, which is banned by the WTO.

The U.S. has launched five separate investigations into Chinese products, including art paper, steel pipe and tyres, since last November.
