GUANGZHOU, Oct. 5 (Xinhua) -- Chinese Vice Premier Hu Chunhua has called for greater efforts to build Guangdong pilot free trade zone (FTZ) into a cooperation model for the Guangdong-Hong Kong-Macao Greater Bay Area.

Hu made the remarks during a research tour of south China's Guangdong Province from Wednesday to Saturday.

The pilot FTZ should speed up its construction as a gateway and hub for high-level opening-up, and promote coordinated regional development, Hu said.

More efforts should be made to expand key overseas markets, promote the development of cross-border e-commerce, and give play to the important role of exhibition platforms such as China Import and Export Fair, he said.
