BEIJING — In the latest restriction on foreign entertainment biz in China, the country’s culture czars will impose controls on all so-called network music imported into the country and require that all online music be registered with the Ministry of Culture.

Network music — the term refers mainly to music played on, and downloaded from, the Web or provided by mobile phone servers — must be imported by ministry-appointed “legal units.” Otherwise, punishment will be incurred, the official Xinhua news agency reported.

The guidelines also forbid the establishment of foreign-funded firms offering network entertainment services, while other businesses working with network music must seek approval from the ministry. Any network music businesses already active must register with the Culture Ministry by March.

Earlier this month, China called a halt to new foreign investment in TV and film production companies, telling international media groups to work instead through individual projects with local partners.
