In the report of 19th NCCPC, the free trade port is granted to undertake the legal status of“off-shore”of the free trade zone in China, highlighting its important missions of strengthening and deepening the reform efforts of offshore financial market in the free-trade zone. Under the precondition of lacking effective supervision on market access, management and exit, all countries believe that the offshore financial market is at risk of losing control of shocking the onshore economy. Therefore, the practices outside the country has been enlightened that although it is unnecessary to discriminate against the national identities of offshore financial institutions, the regulation of reserve requirements still needs to remain. In addition, the regulation of market operation is not limited to the monetary business, being allowed to expand into the field of financial derivative. The subjects of the transaction are restricted to non-residents and the trading currencies even spread to their own currencies. Moreover, the risk early warning mechanism, the lender of last resort system and the deposit insurance system can be used for reference. Thus, it is recommended to take the examination and approval rather than completely to eliminate the admittance of foreign institutions firstly. Secondly, the reserve requirements for funds between offshore accounts and onshore accounts are still needed. Last but not least, China needs to strictly regulate transactions between onshore and offshore accounts and allow RMB to be used as a trading currency in the free trade port.
