From January 2 to 13 2017, His Holiness the Dalai Lama is holding a popular Tibetan Buddhist teaching called Kalachakra in Bodh Gaya, India. Increased restrictions from the government of China has barred Tibetans in Tibet from attending the teachings.

Citizen Lab Researcher Lotus Ruan was interviewed by VOA Mandarin on the recent release of the report entitled “One App Two Systems, How WeChat uses one censorship policy in China and another internationally.”

Director Ron Deibert spoke to CNN International on Citizen Lab’s recent report, titled “One App, Two Systems: How WeChat uses one censorship policy in China and another internationally.” Deibert commented on trends of censorship and surveillance in China, and Asian instant messaging applications more broadly.
