The government-backed CIIRC has cited  a total19 new websites for containing content that "perverts social morals and harms the physical and mental health of children," according to Pacific Epoch.

China's Ministry of Industry and Information Technology has warned that websites not registered with the government by Feb. 24 will be shut down.
