China has blacklisted 38 Japanese cartoons, including the megahit "Attack on Titan," from appearing online, according to state media.

Amid a broadening crackdown on the country's Internet content, 29 Chinese websites have received warnings or fines for carrying shows that "encourage juvenile delinquency, glorify violence and include sexual content," the Xinhua News Agency said Monday.

Another eight websites have been shuttered, it said.
