BEIJING — Three more free trade zones (FTZs) in Guangdong, Tianjin and Fujian, and improvements to the Shanghai FTZ were approved at a meeting of the Political Bureau of the Communist Party of China (CPC) Central Committee on March 24.

FTZs are important for exploring new paths and acquiring new experiences, said a statement released after the meeting.

The statement said the Shanghai FTZ has made “positive progress” over more than a year, generating a model that can be replicated elsewhere.

The Shanghai FTZ, launched in September 2013, is a testing bed for reforms that range from administration, investment, finance through services.

The new zones, as well as the Shanghai FTZ, will continue working for institutional innovation, according to the statement.

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.
