China has established a complete institutional framework with the "Data Security Law" and "Personal Information Protection Law" as the core, and the "Regulations on Promoting and Regulating Cross-border Data Flows" as practical guidelines, and established the core principle of "integrated development and security. This system not only clarifies the security bottom line of data exit, safeguards national security and personal rights and interests through classification and grading protection, security assessment and other systems, but also stimulates the value of data elements through a series of facilitation measures, creating a stable and predictable compliance environment for multinational enterprises.

Multinational enterprises need to focus on three major compliance points: first, the classification of data exit routes, important data or large-scale personal information (with a total of more than 1 million people) need to be declared for security assessment, and medium-scale personal information (100000-1 million people) need to sign standard contracts or pass certification; The second is to fulfill the security obligations of the whole process, including data classification and identification, risk assessment, deployment of security technical measures, and immediate reporting of data security incidents; third, to follow the rules of special areas, key information infrastructure operators need to meet additional requirements related to data localization, financial, automotive and other industries need to refer to the implementation of special guidelines.

In order to reduce the compliance cost of enterprises, China has introduced a number of breakthrough convenience measures: clear cross-border shopping, human resources management and other 7 types of exemption from declaration, covering most daily business scenarios; The "negative list" system has been implemented in the free trade pilot zone, and the data outside the list can be freely exported, which has been effective in 17 areas. Optimize the evaluation process and reduce the average processing time limit to 30 working days, and open a green channel for foreign-invested enterprises. These measures have reduced the average monthly acceptance of data outbound security assessments by 60%, significantly improving flow efficiency.

Multinational enterprises need to build a full-chain compliance system: first, establish a data asset ledger, accurately identify the boundary between important data and personal information, and avoid misjudgment of declaration obligations; Secondly, make good use of facilitation channels. Qualified businesses can simplify the process through exemption from declaration. Enterprises in FTZ can optimize data flow with reference to negative lists. Furthermore, strengthen technical support and deploy security measures such as data encryption and access control, meet the full-cycle requirements of "pre-assessment, in-process monitoring and post-disposal"; Finally, strengthen policy tracking and keep abreast of the rules through the consultation channels and publicity activities of the Internet and Information Department.

China is promoting cross-border data governance cooperation with an open attitude, and has established a data policy exchange mechanism with the European Union and Germany, and introduced a special policy on cross-border data flow in the Guangdong-Hong Kong-Macao Greater Bay Area. The future rules will continue to be optimized: on the one hand, refine industry-specific guidelines to provide more accurate compliance standards for automotive, pharmaceutical and other fields; on the other hand, promote international mutual recognition and explore the establishment of a "white list" of cross-border data flows with relevant countries ". Multinational enterprises should grasp this trend, tap the commercial value of cross-border data flow on the basis of compliance, and achieve a balance between security and development.
