(Reuters) – Chinese Internet firm Sina Corp said it was fined 5.1 million yuan ($815,038) by Beijing authorities for allowing “unhealthy and indecent content” on its online reading channel and on its main website. Sina was stripped of some online publication licenses last week after being targeted in a pornography crackdown, the harshest punishment yet for a Chinese Internet company in an intensifying online crackdown. The fine was imposed by the Beijing Municipal Cultural Market Administrative Law Enforcement Unit, Sina said in a statement on Friday. Sina said it was currently evaluating the impact of the administrative penalties and the options available to the company.
