NYT columnist Nicholas Kristoff on how China's authoritarian regime is undercutting itself by allowing broadband Internet access. He also talks about the efforts of one determined citizen journalist.

Some excerpts:

The collision between the Internet and Chinese authorities is one of the grand wrestling matches of history, visible in part at www.yuluncn.com.

That's the Web site of a self-appointed journalist named Li Xinde. He made a modest fortune selling Chinese medicine around the country, and now he's started the Chinese Public Opinion Surveillance Net - one of four million blogs in China.

Mr. Li travels around China with an I.B.M. laptop and a digital camera, investigating cases of official wrongdoing. Then he writes about them on his Web site and skips town before the local authorities can arrest him.

His biggest case so far involved a deputy mayor of Jining who is accused of stealing more than $400,000 and operating like a warlord. One of the deputy mayor's victims was a businesswoman whom he allegedly harassed and tried to kidnap.

Mr. Li's Web site published an investigative report, including a series of photos showing the deputy mayor kneeling and crying, apparently begging not to be reported to the police. The photos caused a sensation, and the deputy mayor was soon arrested.

Another of Mr. Li's campaigns involved a young peasant woman who was kidnapped by family planning officials, imprisoned and forcibly fitted with an IUD. Embarrassed by the reports, the authorities sent the officials responsible to jail for a year.

When I caught up with Mr. Li, he was investigating the mysterious death of a businessman who got in a financial dispute with a policeman and ended up arrested and then dead.

All this underscores how the Internet is beginning to play the watchdog role in China that the press plays in the West. The Internet is also eroding the leadership's monopoly on information and is complicating the traditional policy of "nei jin wai song" - cracking down at home while pretending to foreigners to be wide open.
