Chinese Premier Wen Jiabao said Monday the world economy still faces prominent systemic and structural risks as the impact of financial crisis has not been fully eliminated.

"The underlying impact of the international financial crisis has not been fully eliminated, the world economy has yet to enter a benign cycle of steady growth, and systemic and structural risks are still prominent," Wen said at the opening ceremony of the Summer Davos forum in north China's port city of Tianjin.

Major problems China still faces include unreasonable economic structure, weak capabilities for scientific and technological innovation, rising resources and environmental constraints, uneven urban-rural and regional development and lack of coordination between economic and social development, he said.

To address the problems, "we will take an integrated approach that balances near-term macro control with long-term development and advances reform and opening-up in the broader context of scientific development," he said.
