The decision to increase the number of free trade zones (FTZ) will help open up the economy and invigorate growth, experts say.

A landmark policy document the Communist Party of China (CPC) released on Friday shows the importance of the Shanghai pilot FTZ. The document was approved by the Third Plenary Session of the 18th CPC Central Committee, a four day meeting that ended on Nov. 12.

"On the basis of pushing forward development of the existing pilot FTZ, qualified regions will be selected to build free trade zones or ports," the document said. This decision means more free trade zones, and they will be brought online quickly.
