China has expressed strong dissatisfaction with and firm opposition to the U.S. government's sanctions on Chinese companies, said Foreign Ministry spokesman Qin Gang in Beijing Wednesday.

The United Sates announced on Tuesday it was imposing sanctions on six Chinese companies which were accused of supplying Iran with military equipment and technology.

Asked to make comments on this issue, Qin said that the U.S. government imposed the sanctions in line with its so-called domestic law. "We are strongly dissatisfied with and firmly opposed to the U.S. move," he told the press.

The Chinese government has always held a serious and responsible attitude toward the non-proliferation issue and has adopted a series of effective measures to strengthen export management and control, the spokesman said.

The U.S. move was not beneficial to China-U.S. cooperation in the non-proliferation field, Qin said, demanding the United States change this wrongful action.
