Note:
(a) In the public domain, I can not find who the Chinese attendees are (but see (c) below). In part because anybody may attend, after having made a reservation. See next.
(b) This is the invitation.
"Chen Guangchen, a Chinese civil right activist; Lu Pin, Chinese feminist activist; Rebiya Kadeer, President of World Uyghur Congress; Teng Biao, lawyer and human rights activist; Ti-Ann Wang, daughter of a Chinese activist currently serving a life sentence in China's prison, and Tsering Kyi, a blogger and poet who works at VOA's Tibetan Service were among the presenters at the event.
"Tsering Kyi spoke about the current situation inside Tibet and her nephew, who self-immolated to protest China's policies towards Tibetans in 2013.
"The event also reserved an empty chair to represent the human rights defenders who still remain in Chinese custody; in prison, house-arrest, or victims of enforced disappearances.
* As you can see, the photo of this report showed not many Asian attendees.
