BEIJING -- Chinese authorities on Monday released a master plan for the Hainan free trade port, which aims to build the southern island province into a globally-influential high-level free trade port by the middle of the century.

A free trade port system focusing on trade and investment liberalization and facilitation will be "basically established" in Hainan by 2025 and become "more mature" by 2035, according to the plan jointly issued by the Central Committee of the Communist Party of China and the State Council.
