As China's leaders gather in Beijing this week for the 19th National Congress of the Chinese Communist Party (CCP), an ideological war is under way on the country's internet. Some experts predict President Xi Jinping will use the meeting to establish a level of control and influence over the Party not seen since Mao Zedong, the strongman founder of the People's Republic. While the internet has always been a key battleground for the Party, the past 12 months have seen a marked increase in censorship, with new laws and regulations targeting online expression even in areas or on certain topics where dissent was once tolerated or passed undetected.
