In order to realize these characteristic functions under high-level opening conditions, there is still an unresolved legal basis for authorization in the rule of law, the fragmentation of the free trade pilot zone (port) legislation and the lack of connection with foreign investment legislation, and the lack of a coordination mechanism with countries and regions along the new western land-sea corridor , A series of legal issues such as the failure to realize the rule of law of the evaluation, decision-making, and feedback mechanism. Therefore, the construction of the rule of law in the China Pilot Free Trade Zone (port) should adhere to the combination of the rule of law positioning and problem orientation, further clarify the rule of law positioning of the Pilot Free Trade Zone (Port) under high-level open conditions, and strengthen the country’s legislation on the Pilot Free Trade Zone (Port). To formulate the basic law of the Pilot Free Trade Zone (Port), copy and promote the legalization of the mechanism from internal differentiation legislation to “Belt and Road” linking legislation, so as to implement and promote China’s freedom in a layered, step-by-step, and focused manner.
