Apple has always been known for having very strict guidelines all developers they must continue if they want to dedicate their applications to the App Store, even though they sometimes use tricks to mask their tasks and train them until they are available. If you are also a developer in China, there is one more filter that they should slow down for developers.
Developers offering games on the App Store must first obtain approval from the Chinese government, which they obtain in the form of a number, the number to send to Apple for a company founded by Cupertino to make sure that it has truly transferred control of the country's government.
This state law, approved in 2016, only affects engineers who want to do so provide your applications in mainland China. The person responsible for reviewing the applications that are intended to be available in the app store is the General Administration of Press and Publisher of China, which is the administration that assesses the level and severity of the application and the vocabulary used.
Although it has been 4 years, it has not been until now when the government started forcing compliance. In an email sent by Apple to the developer community, you can read:
Chinese law requires games to obtain a number approved by the General Administration of Chinese Press and Publisher. As a result, please provide us this number before June 30, 2020 for any paid games or games that offer purchase on App Store China that you intend to distribute in China.
In the same email, Apple does not report possible consequences for developers who do not comply with the new law, but it is very likely Your applications are disappearing from App Store China. Once again, Apple is forced to follow local laws. Since the Google Play Store is not available in China, this new rule only affects the iOS ecosystem.
