The author Zhang Yihe and prominent journalist Gao Yu said they had lost some or all of their access to WeChat, China’s dominant social media platform. Academics including Guo Yuhua, the outspoken Tsinghua University sociologist, and He Weifang, the Peking University law professor, reported similar issues.
Ahead of the Games, authorities also detained two prominent human rights activists: the lawyer Xie Yang and writer Yang Maodong. They are held on suspicion of “inciting state subversion”. A third rights lawyer, Tang Jitian, went missing in December en route to an EU human rights day event in Beijing.
