I don't think "Jasmine Revolution" will spread to China, at least not on a wide scale. If you examined the situation closely, you can see that countries that are going through such revolution all have similar traits below:
- Authoritarian regime
- Wide-spread unemployment amongst 30 and under (>30%)
- Dramatic food inflation (>10% annually)
- Population explosion putting more pressure on limited resources
China might get dinged for two of those above (regime and inflation). However, China is capable of feeding most of its citizens with its agricultural system, therefore moderating food inflation to aroung 5% per year. Unemployment is a problem in China, but it's not a matter of job shortage. There are plenty of low-skill jobs available which go unfilled because many young people with post-secondary education see those as beneath them. China's population growth has been stablizing for several years now, and will begin to decline in the next few decades.
Revolution is very unlikely in a society going through high speed economic growth. Problem starts when that growth is halted and there is no democratic means for people to demand change. I don't know if anybody saw the protest in Beijing several days ago. There were more journalists and onlookers than actual protesters.
