Three more free trade zones (FTZs) in Guangdong, Tianjin and Fujian, and improvements to the Shanghai FTZ were approved at a Tuesday meeting of the Political Bureau of the Communist Party of China (CPC) Central Committee.
Â
FTZs are important for exploring new paths and acquiring new experiences, said a statement released after the meeting.
Â
The statement said the Shanghai FTZ has made "positive progress" over more than a year, generating a model that can be replicated elsewhere.
Â
The Shanghai FTZ, launched in September 2013, is a testing bed for reforms that range from administration, investment, finance through services.
Â
The new zones, as well as the Shanghai FTZ, will continue working for institutional innovation, according to the statement.
Â
The FTZs are part of a new, more open economic system, exploring new models for regional economic cooperation, and establishing a law-based climate for business and commerce, the statement said.Â
