A popular science writer has prepared a lawsuit against a former talk-show anchor, claiming his reputation was damaged during online debates.

Fang Zhouzi, a writer who popularizes science online, has claimed that former CCTV host Cui Yongyuan libeled him on the Internet during a heated discussion about genetically modified food.

Fang wants Cui to delete his postings and apologize. He is also asking for 300,000 yuan ($49,700) in compensation.
