China’s ‘Great Firewall’ has evolved into the most sophisticated system of online censorship in the world. As the Chinese internet grows and online businesses thrive, speech is controlled, dissent quashed, and attempts to organise outside the official Communist Party are quickly stamped out.
 
Updated throughout and available in paperback for the first time, The Great Firewall of China draws on James Griffiths' unprecedented access to the Great Firewall and the politicians, tech leaders, dissidents and hackers whose lives revolve around it. New chapters cover the suppression of information about the first outbreak of COVID-19 in Wuhan, disinformation campaigns in response to the exposure of the persecution of Uyghur communities in Xinjiang and the crackdown against the Umbrella movement in Hong Kong.
