The G20's representativeness and influence cannot be replaced by any mechanism, Foreign Ministry spokeswoman Hua Chunying said at a regular press briefing on Monday.

Hua was responding to a question on whether she regarded the G20 as a more effective platform of economic governance than the G7.

"The G20 is a main platform for international economic cooperation which is widely recognized, its representativeness and influence can't be replaced by any mechanism," Hua said.

"China is about to host the G20 summit this September. We hope the Hangzhou summit will reach a consensus, face global economic challenges and point the direction for world economic growth and cooperation," she added.

Concerning remarks by Japanese Prime Minister Shinzo Abe at the G7, blaming the slowdown in emerging markets for dragging down world economic growth, Hua said every country had their views on the challenges facing the global economy and how to solve these challenges. "It can't be influenced by any individual country's self-interest," she said.

"In the current situation, the international community is looking forward to the partnership of rowing in the same boat and undertaking concrete actions to promote development and build confidence," Hua added.
