China’s new “Administrative Measures for National Cybersecurity Incident Reporting” take effect today, November 1, 2025. These rules clarify and structure the obligations for organizations to report cybersecurity incidents to the government, particularly those affecting critical infrastructure or involving significant data loss.
Business Impact
This creates new, complex compliance obligations for multinational corporations operating in China. The rules define specific timelines and criteria for what constitutes a “significant” incident, increasing legal and operational burdens. Failure to comply can result in severe penalties and sanctions.
Why It Happened
This is part of China’s broader effort to strengthen its control over data and network security, address emerging AI-related risks, and enhance its visibility into cyber threats affecting its national infrastructure.
Recommended Executive Action
Engage legal and compliance counsel specializing in China’s cybersecurity laws. Direct the CISO and regional leaders to update incident response plans to incorporate these new mandatory reporting timelines and procedures to ensure compliance.
