New Delhi: The Chinese regulators have imposed limits on the number of lucrative healthcare adverts carried by Baidu, China’s biggest search engine. The limits were imposed after the death of a student who underwent experimental cancer treatment which he found on Baidu.
 
Before he died, Wei Zexi denounced the firm online as “evil” and warned other cancer patients “not to be cheated”.
 
Baidu’s shares have dropped since the controversy over the student’s death erupted.
 
The death of Zexi led to huge protests in China, forcing Baidu to reexamine its healthcare adverts. The company said the investigation has started and it would fully cooperate with the regulators.
 
Healthcare accounts for 20 to 30 percent of the Baidu’s search revenue.
