have financial banking data on them." For businesses, a social credit system could also be used for micro enterprises, which couldn't be assessed with traditional criteria. Hoffman isn't buying that argument, saying such a system is about government power. "If solving problems was the real goal, the CCP would not need social credit to do it," she says. "China’s social credit system is a state-driven program designed to do one thing, to uphold and expand the Chinese Communist Party’s power." She adds that social credit is a tech-enabled way to tie political power to social and economic development that's been discussed in the country since the 1980s, an automation of Chairman Mao's Mass Line — a term to describe how the party's leadership shaped and managed society. "In Mao’s China, the Mass Line relied on ideological mass mobilisation, using Mao Zedong’s personal charisma, to force participation," Hoffman says. "The CCP could no longer, after the Mao era, rely on ideological mobilisation as the primary tool for operationalising social management." Is there more than social credit? China's social credit scheme is developing, but it is only one part of the country's surveillance state.

Ahead of the 30-year anniversary of the Tiananmen Square protests researchers at the University of Hong Kong found that critical posts on the social networks of Weibo and Wechat were removed.
