internet - Between freedom and control

I just received the book "The Internet in China. Unlocking and Containing in the Public Sphere" by Johan Lagerkvist of the University in Lund. I'm currently wading through business plans and other proposals (hence the light blogging too), but the introduction is already very promising. It deals with the - almost ideological - views on how the internet in China is developing, on one hand offering a much wide freedom to much of its citizens, on the other hand is becoming more sophisticated in containing the freewheeling discussions.
Lagerkvist's two questions:

1. How can Internet use contribute to an unlocking of the public sphere, making it more unfettered and independent from party-state control?
2. While generally promoting Internet use throughout the country how are agents of the Chinese part-state explicating containment of this use, for themselves and to the larger population, as part of their efforts to maintain control over politics in a locked-in publis sphere?

Will keep you updated as I move on.
