News of major unrest in China. There hasn't been a whole lot of media attention to these protests compared to those in the Middle East and Greece.
Hmm...I'm cautiously skeptical. I have regular interaction with a variety of people in the PRC, and haven't heard a peep of this. Not saying that those events didn't happen, just that their importance in terms of snowballing into something larger is probably pretty low.
The two bombing events are, sadly, not unheard of. In the past it's been directed more at companies than government, but it's not the first time someone has taken out their frustrations on the local government (and often with some cause).
The one in Zengcheng is what I'd keep my eye on. There are roughly 210 million "floating people" (
liudong renkou) -- internal illegal immigrants -- and I'm assuming this is what the article meant by "migrant workers". These are Chinese who have moved from the countryside or smaller cities into the major coastal cites looking for work. They're a great source of ultra-cheap labor with no legal rights, but like all migrant workers they typically get the shit end of the stick, even from their own countrymen. They're blamed for rising crime, they're accused of stealing jobs and depressing wages, and they typically kicked out of town when the local Party officials decide to make a show of doing something about it.
Liudong renkou riots, if they grew widespread, could be a serious problem.
