Evening news here is showing more anti-japan riots on Sunday in Guangzhou and Shenzhen. Video of protestors climbing up billboards and cutting up ads for Sony and Epson. Apparently the Japanese government has asked the Chinese government for reparations for Saturday's protest in Beijing that damaged the Japanese embassy.

And since Sunday's SCMP isn't online, I'd like to point to the stories on page 6 of the National Section with photos from Saturday's protest. The cross-sheet headline is "Beijing sees biggest protest since 1989". The second story in the single right column on the page is titled, "How rigid crowd control measures backfired" by Shi Jiangtao and Vivian Wu.

The protest was largely peaceful until the police, who had diverted the marchers to a less crowded area in Zhongguancun, confronted demonstrators who insisted on marching on the main streets.

According to Chen Henan, a leader of the protest, the mood of demonstrators changed when police forced the crowd to march far away from the Japanese embassy.

"I had to dismiss the crowd when some emotional participants confronted me and insisted on marching towards the Japanese embassy, some 30km away, which was against the government's will," said the 22-year old graduate student from Renmin University.

This intervention to divert the protestors was before the vandalism and violence at the Electronics Shopping Center. Coming home last night there was a brief flash on the news ticker on the MTR that the protestors had not dispersed yet. Check this article from Reuters Saturday night (local time)

At 9.30 p.m. (2:30 p.m. British time), the main remaining crowd of about 1,000 protesters was turned away from marching towards the political heart of Beijing, Tiananmen Square, where a pro-democracy student protest was crushed with massive loss of life on June 4, 1989.

The crowd, signing and chanting, was turned instead back towards the Japanese embassy which was guarded by line of city police and behind them five lines of riot police with shields.
