Hainan: In accordance with the principle of "taxation shall be fully paid", the policy of free trade port will be incorporated into the "efficiently accomplishing one task" principle.

The People's Government of Hainan Province issued the "Twenty Key Measures for Supporting Enterprises in Hainan Province", proposing to strengthen the implementation of policies related to the free trade port. Provincial departments should establish a system for interpreting free trade port policies based on the "45432" modern industrial system and policy types, and appoint dedicated personnel for interpreting these policies to provide comprehensive, accurate, scientific, and timely policy interpretations to businesses. The Department of Business Environment Construction of the province will compile and release the contact information of the free trade port policy interpreters to the public, offering consultation services. A mechanism will be established for the efficient implementation of free trade port policies, following the principle of "should be done, must be done," by incorporating these policies into the process of "efficiently completing a task." If there are any issues with the implementation of free trade port policies, when cities, counties, or parks submit clear opinions to relevant provincial departments, these departments are generally required to provide a response within 10 working days. If the situation is complex and requires further research and clarification, this should be communicated promptly.
