Culture and Internet authorities are planning to develop China-specific criteria for diagnosing minors' addiction to online gaming, according to a workplan jointly issued by 15 ministry-level authorities on February 17.

China's online gaming industry took in revenue worth 24.84 billion yuan ($4 billion) in the first half of 2012.

However, minors' addiction to online gaming has caused serious social problems, which sometimes lead to juvenile crimes, said officials with the Ministry of Culture.

Approximately 150 million of China's Internet users are believed to be below the age of 19.
