China will play a constructive role in helping resolve hot issues and global problems, Chinese Premier Wen Jiabao said at the opening of the parliament's annual session on Saturday.

"China will take an active part in multilateral diplomacy, and use the G20 summit and other diplomatic forums as the main platform for strengthening the coordination of macroeconomic policies," Wen told deputies to the Fourth Session of the 11th National People' s Congress (NPC).

Through the platform, China will advance the reform of the international economic and financial system and fulfill the country's international responsibilities and duties, the premier said.

China will maintain the sound, steady development of its relations with major powers, actively promote dialogue and cooperation, and expand common interests and the foundation for cooperation, he noted.
