Investment aid will be a new feature of the global economic pattern and China is adapting it to implement reforms, said Chinese economist Wu Jinglian on Friday.

Wu said at the 5th Caixin Summit that China is experimenting with the Shanghai Pilot Free Trade Zone and lessons learned are being copied to other regions.

The basic service of the trade zone is to assist with trade and investment, and build a market-oriented, global and law-based business environment, said Wu.

"China is helping improve the trade and investment rules of the global economic system".
