If I were the chinese government, I would do what the US do: Declare loudly the importance of free speech, human rights etc. while infecting every server with trojans, using the cheap human resource to clickfarm positive wikipedia articles, use machine learning and neural network to recognize dissident patterns on the internet and target them specifically, spy on the population while condamning other countries for citizen surveillance, and most importantly, scream as loudly as you can about how crucial human right is while secretly spending $$$ on extraordinary rendition.
