China tightens controls on ads

BEIJING: China's internet regulator said on Saturday that search engines should tighten management of paid-for ads in search results, making clear which results are paid-for and limiting their numbers.

The Chinese government already exercises widespread controls over the internet and has sought to codify that policy in law.

Chinese regulators last month imposed limits on the number of lucrative healthcare adverts carried by Baidu Inc following the death of a student who underwent an experimental cancer treatment which he found using China's biggest internet search engine.

Wei Zexi, 21, died in April of a rare form of cancer, and the case sparked widespread public anger.

The Cyberspace Administration of China said search engines should investigate the "aptitude" of clients offering paid-for ads, set a clear upper limit on such ads and clearly distinguish which are paid-for ads and which come from "natural searches".

"Internet search providers should earnestly accept corporate responsibility toward society, and strengthen their own management in accordance with the law and rules, to provide objective, fair and authoritative search results to users," it said.

Users have been particularly concerned with medical ads, which are a threat to people's health, the regulator added.

Baidu said in a statement that it was committed to providing the best search experience and will fully comply with the law.
