Spokesman of Chinese Ministry of Commerce Chong Quan here Friday made a call to related departments of the United States and the European Union that they should show their political willingness to push forward the Doha talks.

The United States and the European Union should work out the negotiation pattern as soon as possible, so as to help the Doha round trade talks to be concluded by the end of this year, he said at a press conference.

"We are regretful that the just-concluded World Trade Organization (WTO) informal ministerial meeting in Geneva made no progress," he said.

China insists on the general goal of concluding the Doha talks by the end of this year, so the negotiation momentum must be maintained, he said.

China always plays a constructive role in the Doha trade talks, willing to enhance consultations and cooperation with various parties in a bid to end the Doha talks by the end of this year with an overall achievement of equilibrium, he said.
