Chinese censorship following the death of Li Keqiang
As part of our ongoing project monitoring changes to Chinese search censorship, we tracked changes to censorship following Li Keqiang’s death across seven Internet platforms: Baidu, Baidu Zhidao, Bilibili, Microsoft Bing, Jingdong, Sogou, and Weibo.

Our results demonstrate China’s ongoing efforts to push state-sanctioned narratives concerning politically sensitive topics, impacting the integrity of the online information environment.
