Chinese Vice Premier Wang Qishan Wednesday pledged to push forward the new round of talks at the World Trade Organization (WTO).

"China will work with all sides to push the Doha round of talks to success," Wang told WTO Secretary-General Pascal Lamy, who is in China for the Shanghai World Expo.

Wang said China firmly opposes trade protectionism and actively strives for free trade.

Wang also said China hopes to promote mechanisms for mutually beneficial trade.

Lamy stressed the importance of the Doha round of WTO talks and hailed the positive role China is playing in the process.
