China has officially entered a new phase in cyber regulation. Starting January 1, 2026, the revised China Cybersecurity Law, the most substantial update since its 2017 inception, is now in effect. The amendments establish new standards for incident response, accelerate penalty enforcement, and broaden jurisdictional authority—extending oversight over foreign entities. Organizations with operations in China, those selling products or services into the Chinese market, or entities tied to Chinese critical infrastructure must now meet stricter compliance demands. The law shifts away from drawn-out investigation processes and phased remediation toward requiring rapid response, explicit accountability, and direct regulatory interaction.
Near‑Real‑Time Incident Reporting
Tighter timelines now mandate that operators of critical information infrastructure must notify regulators of major cybersecurity incidents within 60 minutes, or at most four hours, stressing near-real-time disclosure.
These mandates are consolidated under the Administrative Measures for National Cybersecurity Incident Reporting, enforced by the Cyberspace Administration of China (CAC) as of November 1, 2025.
Incident severity is categorized into four levels. "Relatively major" incidents—such as data breaches affecting over one million individuals or losses exceeding RMB 5 million (~USD 700,000)—must be reported within four hours, followed by a detailed report within 72 hours and a comprehensive review within 30 days. For “particularly serious” incidents, reporting must occur within one hour; regulators must notify the CAC and State Council within 30 minutes, escalating to highest government levels.
Harsher Penalties and Personal Liability
Fines up to RMB 10 million now apply to organizations, with individuals responsible potentially fined up to RMB 1 million.
The enforcement process is streamlined—regulators can bypass warnings and corrective steps to impose penalties immediately.
Supply chain responsibility is tightened: using non-compliant products or services may result in fines up to ten times their purchase value, raising vendor management stakes.
Expanded Extraterritorial Jurisdiction
The revised law now applies to any foreign activity that endangers China’s network security, not just those targeting critical infrastructure directly.
Authorities may impose asset freezes or sanctions for serious violations, adding global operational risks for multinational companies with China-linked supply chains, cloud services, software, or hardware.
AI Governance Embedded in Law
For the first time, the law explicitly addresses artificial intelligence, promoting its use for cybersecurity while enforcing ethics and safety oversight.
Though strategic in tone, implementation details will be set out in future regulations and technical standards. The inclusion of AI signals a move toward algorithmic accountability.
Defined Thresholds for Severe Incidents
The CAC specifies definitions for “particularly serious” incidents, including those affecting:
- Government portals, major news websites, or critical infrastructure for over 24 hours (or six hours if system-wide failure)
- Disruptions to services for more than 50% of a province's population or impacting over 10 million people (utilities, transportation, healthcare)
- Large-scale data breaches affecting over 100 million citizens or losses exceeding RMB 100 million (~USD 14 million)
Post-resolution, network operators must submit a comprehensive 30-day report detailing root causes, response actions, impacts, corrective steps, and lessons learned.
Global Compliance Implications
Supply chain dependencies connected to Chinese infrastructure now face substantial compliance pressure. Security leaders must ask:
- Can Security Operations Centers identify incident severity and report within 60 minutes?
- Do teams have the authority and processes in place to notify regulators immediately?
- Is the evidence pipeline robust enough for near-real-time documentation?
Global enterprises tied to China must treat these updates as legally binding requirements. Speed, thorough documentation, and executive accountability are no longer best practices—they are legal imperatives in China’s cybersecurity regime.
