Meaning
Statutory mandate requiring personal and important information collected by critical infrastructure operators or specific processors to be stored on servers physically located within the national territory. Data localization is a core component of the Cybersecurity Law and the Data Security Law of the People’s Republic of China. It dictates that certain types of data generated within the country cannot be transferred to overseas servers without undergoing a rigorous security assessment by the Cyberspace Administration of China.
This rule applies to any organization that handles a large volume of personal information or information that is deemed sensitive to national security or the public interest. The boundary of this requirement is defined by the volume of data processed and the specific industry in which the organization operates. If an entity falls under the definition of a critical information infrastructure operator, the localization requirement is absolute for all data related to its core functions.
Storage Mandate
Physical hosting of databases must occur on infrastructure that is legally and geographically situated within the borders of the mainland. Data localization requires that the primary copy of the information be kept on local servers, even if a secondary copy is permitted to be sent abroad after a successful audit. This mandate prevents the circumvention of national oversight by moving data to jurisdictions with different privacy or security standards.
Organizations must ensure that their cloud service providers or internal data centers comply with the national standards for physical security and administrative access. The requirement also extends to backup and recovery systems, which must be maintained within the same jurisdictional boundaries. This ensures that the data remains accessible to the state authorities for regulatory or legal purposes.
Security Assessment
Mandatory review by the cyberspace authority is the gateway for any organization that needs to export localized data to a foreign recipient. Data localization is enforced through a process where the data processor must demonstrate that the transfer is necessary and that the receiving party can provide an equivalent level of protection. The assessment looks at the volume of the data, the sensitivity of the information, and the potential impact on national security if the data were to be compromised.
This process involves the submission of a detailed impact assessment report and a copy of the contract between the sender and the receiver. If the risk is deemed too high, the authority may deny the transfer or require the organization to further anonymize the data before it leaves the country. This creates a high administrative burden for multinational companies that rely on global data sharing.
Access Control
Administrative restrictions on who can view or manage the localized data are a critical part of the domestic compliance framework. Data localization involves not only the physical location of the hardware but also the nationality and location of the personnel with administrative privileges. The state expects that the management of localized datasets be handled by local teams who are subject to the domestic laws of the country.
This prevents foreign entities from exercising remote control over sensitive information without any local accountability. Organizations must implement strict authentication and logging systems to track every instance of data access or modification. Any unauthorized access must be reported to the relevant authorities within the timeframe specified by the law.
This oversight is intended to prevent data breaches and to ensure that the information is used only for the purposes for which it was collected. The legal framework continues to evolve as new regulations for specific sectors are released.
