MIIT
MIIT is China's ministry for industry and information technology, and it sets the rules for telecom networks, spectrum, numbering and filings.
Definitions only — a term explained here is not a service we sell.
MIIT is the Chinese ministry that sets policy for telecom networks, radio spectrum, numbering, internet services and ICP filing. Provincial communications administrations administer much of the day-to-day work. Specific applicability is scoped with counsel.
MIIT publishes regulations and notices. Cross-border circuits, numbering, website filing and app filing all have a MIIT or provincial dimension, and the rules change, so confirm the current requirement.
Where MIIT stops
MIIT does not replace other regulators. Data protection, encryption and cybersecurity rules involve other bodies, so a compliance plan that names only MIIT is incomplete.
Ask which entity holds the approval or filing, what its scope covers, and whether a change of supplier or route needs a new one. Get the approval number and verify it. This is general information, not legal advice. The China compliance page is a starting point.
