China Finalizes Data Security Law


On June 10, 2021, the final version of Data Security Law (DSL) of the People’s Republic of China was published, and the DSL will take effect Sept. 1, 2021. Prior to the issuance of the final version, two drafts of the DSL were released to the public seeking comments, in July 2020 and April 2021, respectively. While the DSL provides for a three-level data classification system, the obligations for each classification level are described in vague and broad terms, making it likely that in the near future a regulation or official documents will be released that contain the precise compliance responsibilities.

Scope and Application of the DSL

The DSL applies broadly to both online and offline data processing activities. Article 3 of the DSL provides the definition of “data,” “data processing,” and “data security.” Under the DSL, “data” refers to any record of information in electronic form or other form, “data processing” refers to the collection, storage, use, processing, transmission, provision, and disclosure of data.

The DSL not only regulates the domestic data processing activities but also has extraterritorial reach. Article 2 of the DSL provides that it applies to the data processing activities and data security regulation performed within the territory of the People’s Republic of China, as well as the data processing activities performed outside of the territory of the People’s Republic of China that threaten national security, public interests, or the legitimate rights and interests of the citizens or organizations of the People’s Republic of China.

Data Classification Protection System

A data protection system with three classification levels will be implemented on a national scale. Classification will be determined based on the data’s level of importance to economic and social development, and the scale of potential harm to national security, public interest, or the legitimate rights and interests of individuals or organizations in the event that the data are tampered with, destroyed, leaked, or illegally obtained or used. “National core data,” defined in Article 21 of DSL, is the highest level of the three-level system and refers to the data “have a bearing on national security, the lifelines of national economy, people’s key livelihood and major public interests.” The national core data are subject to a stricter management system than that of the “important data,” which is at the middle of the three-level classification system. However, the definition of “important data” is not provided in the DSL. Article 21 of the DSL only provides that (i) the national data security work coordination mechanism shall coordinate with the relevant departments/functions to formulate the catalogues for the important data and strengthen the protection of important data; and (ii) each region and department shall in accordance with the three-level classification data system, determine the specific catalogue for important data for the respective region and department, and of the relevant industries and sectors, and undertake special protection for the data included in such catalogue.

The definition of “important data” is otherwise provided in other legal documents (which can shed some light on such definition under the DSL, although these documents have only been published for public comment and are not finalized). In April 2017, the Cyberspace Administration of China issued a document for public comment – Circular of the Cyberspace Administration of China on Seeking Public Comments on the Measures for Evaluating the Security of Transmitting Personal Information and Important Data Overseas (Draft for Comment), which defines “important data” as “the data closely related to national security, economic development and public interests, and the relevant national standards and guidelines for identification of important data shall apply mutatis mutandis to the specific scope of important data.” Another document, Information Security Technology – Guidelines for Data Cross-Border Transfer Security Assessment (Draft for Comment), published in August 2017 by the National Technical Committee on Information Security of Standardization Administration, provided a similar definition of “important data”: “the data (including raw data and derived data) collected, generated in China by the relevant organizations, institution that are closely related to national security, economic development and public interests, but do not involve the national secrets.”

Under the DSL, the listed responsibilities under the three-level data classification system are vague and broad, making it difficult to know their precise terms and obligations. Therefore, it seems likely that in the near future a regulation or official documents will be released that contain the precise compliance responsibilities. The issuance of the Classification Guidance for Industrial Data (for Trial Implementation) by the Ministry of Industry and Information Technology in February 2020 shows that classification of industrial data has taken place. With less than two months before the Sept. 1, 2021 effective date of the DSL, it is likely more data protection classification guidance or standards will be issued soon.

Data Security Mechanisms

In addition to the above data classification protection system, Chapter III - Data Security Systems of the DSL includes other data security mechanisms that must be established at the national level.

Protection Responsibilities of Data Processors

Chapter IV of the DSL – Data Security Protection Responsibilities – includes the data protection responsibilities of data processors (including entities and individuals, public security organizations, and national security organizations and other competent authorities of China).

Penalties for Violations of the DSL

The penalties imposed by the DSL in Chapter VI – Legal Liabilities for the violations of the DSL – include the issuance of an order to make a correction, and a warning, confiscation of illegal income (if any), imposition of fines to the organization and individual, or concurrently imposition of fines to the directly responsible person or person in charge (if any), issuance of an order to suspend the relevant business, or stop operation for rectification, or revocation of the relevant business permits or business license, or other sanctions in accordance with laws and regulations, and the relevant civil liabilities and/or criminal liabilities shall be imposed. Among the penalties for the various violations, the fines imposed for violation of the management system for national core data and causing harm to national sovereignty, security and development interests, are the most severe, ranging from Chinese yuan 2 million to 10 million.

In addition to the above penalties, the DSL includes one administrative measure: if the relevant competent authorities (in the course of performing their duties) discover any major security risk in data processing activities, they may make an appointment with the relevant organizations and individuals to discuss, and require such organizations and individuals to take corrective measures and eliminate hidden problems.
