A word about restrictions.
There are no restrictions on who can register a .com.cn domain. However, the registry will verify that site content under this domain is harmonious with the laws and values of China. They will delete domain names that they believe breach registration requirements.
The .cn registry is maintained on mainland China by the CNNIC: China Internet Network Information Center. Businesses need to provide a company registration certificate and individuals are asked for a copy of their ID card or passport.
