(Yicai Global) June 2 -- Hainan province-related stocks led the early-bird gainers as the national government announced a new opening policy for its southernmost island province yesterday.

Three benchmark indexes of Chinese mainland stock markets also edged up after vaulting yesterday.

The Shanghai Composite Index set out 0.03 percent up at 2,916.32, while the Shenzhen Component Index rose 0.28 percent to 11,133.62. The ChiNext Price Index, which tracks growth enterprises listed in Shenzhen, increased 0.31 percent to 2,164.99.

Chinese authorities yesterday released a blueprint for a Hainan free trade port that hoisted stocks associated with the island often dubbed ‘China’s Hawaii’ up 78 percent overall in the first five minutes of opening.

To enable the free flow of trade, the breezy, balmy vacation destination, which is also China's largest special economic zone, will roll out measures that center on zero tariffs for the trade of goods, while facilitating both entry and business operations for services providers.

The cross-border flow of funds will be guaranteed, and the FTP's financial sector further opened, which will entail support for setup of trading venues for financial products related to energy, shipping, property rights and equities, as well as clearing centers.

Logistics will be streamlined with the construction of shipping hubs in the New International Land-Sea Trade Corridor, with airspace control over the FTP eased and more flights and air routes launched, per the plan.
