This morning when I was teaching "Human Rights in China", 16 people suddenly appeared in front of my house, holding signs libeling me as a CCP spy. Apparently they are sent by Guo Wengui (Miles Kwok) to harass me because I'm critical of this swindler. 1/n In 2018, Guo Wengui filed a baseless, frivolous defamation lawsuit against me coz I wrote a long article to analyze him and his followers. He totally lost this case a few months ago. He also sued many other people and media who are against him. 2/n

[Thread] A Chinese student group, likely CSSA, threatened Columbia University to cancel a panel discussion on #humanrights in #hongkong #tibet #EastTurkestan #Uyghurs and #China. And they successfully blocked the discussion. An extreme insult to free speech in this country. [Cont.] A statement co-authored by all panelists and the moderator will be out soon. Even in recent months, many similar things happened in US, Australia, Canada and other countries. #CSSA is definitely a weapon of Chinese government.
