Google has changed the way it filters porn to stop it appearing on its Chinese site.
Last week the China Internet Illegal Information Reporting Center watchdog was reported to have complained to Google.
Google said: "Google has been working to remove pornography from our search results in China, in accordance with our operating license there."
"This has been a major engineering effort, and we believe we have addressed many of the problems identified by the Government. As part of these efforts, we have also temporarily disabled the Google Suggest feature on Google.cn. Finally, we have redesigned the home page of Google.cn to remove the radio buttons that offer language and locale options.
"These buttons were used by a very small percentage of our users. All other links on the home page of Google.cn remain unchanged."
The China Internet Illegal Information Reporting Center (CIIRC) said earlier: "Google China has not conducted the oversight required according to China's laws and regulations, and a large volume of foreign internet pornographic information has entered our borders through this website."
The CCIIRC was set up in 2004. It says it is a non-governmental organisation, registered with the Ministry of Civil Affairs of China.
