China needs to strike a balance between maintaining a relatively fast and stable development, economic structural adjustment and management of inflation expectation to avert a possible economic "double dip" this year, Premier Wen Jiabao said?in Beijing?Sunday.

Among the three major tasks, economic restructuring and transformation in development pattern must be given a priority to solve China's economic imbalances, incoherence and unsustainability exposed in the crisis, he said at a press conference after the annual parliament session.

The world is still facing uncertainties in economic recovery with major challenges and problems in the world economy not being fully addressed, which poses risk of a "double dip," he said.

"Without a recovering world economy, China's recovery cannot sustain," he said, noting that despite a domestic economic rebound, a lot of Chinese enterprises have not witnessed improvement in performance and are operating with government support.

Boosted by a raft of stimulus measures, China's economy expanded 8.7 percent in 2009, staging a speedy recovery after being hit by the worst global financial crisis in decades.
