More than 10,000 government departments and officials across China had opened micro-blog accounts by August 1, according a survey by People.com.cn, an online news portal run by the People's Daily.

The survey was based on the micro-blog services provided by Shenzhen-based Tencent, one of China's leading Twitter counterparts.

In April, Shanghai-based Fudan University said in a report that there were 2,400 micro-blog accounts run by authorities and officials.

The total number of micro-bloggers in China soared to 195 million by the end of June this year, according to the China Internet Network Information Center.
