XIAMEN - China's Minister of Commerce Chen Deming said Thursday that the country will continue to make efforts to push forward trade negotiations launched in the Doha Round of the World Trade Organization (WTO), although the window for success is gradually closing.

Chen called on developed and emerging nations to support the drive to exempt tariffs and export quotas for the least developed nations that have been awaiting these results since the Doha Round of trade negotiations among WTO members in Doha, Qatar in 2001.

China is willing to help those nations improve their deep processing capabilities of agricultural products to increase their added-value and benefit their people, Chen told a forum at the ongoing 15th China International Fair for Investment and Trade (CIFIT) in China's southeastern coastal city of Xiamen.
