China will officially launch three new free trade zones (FTZs) on Tuesday, April 21, Chinese state-owned newspaper People’s Daily reported. The zones were approved last year.

The three areas, each covering about 120 square kilometres, are located in Guangdong province, Fujian province and Tianjin city respectively.

The Guangdong FTZ aims to speed up the economic integration with neighbouring Hong Kong and Macao, said the Chinese State Council in a master plan released on Monday. Hengqin Island will strengthen co-operation with Macao in the fields of tourism and commerce, according to the plan.

Macao’s Secretary for Administration and Justice, Sonia Chan Hoi Fan will attend a ceremony in Guangdong to mark the launch of the new free trade zone there, the Macao Government said in a statement.

The three new FTZs are modelled after the Shanghai free trade zone, China’s first such area, established in September 2013. A “negative list” that bans or restricts foreign investment in 122 business categories will apply to the four FTZs, the State Council said on Monday, down from a previous list that included 139 categories.

Chinese Vice Premier Wang Yang will also head a central task force to co-ordinate work between the four FTZs, state media reported.
