A human right concern group on Wednesday called the release of Liu Xia a "special diplomatic gesture" by Beijing, and it does not mean more dissidents would be freed.
Liu, the widow of the late Nobel Peace Prize laureate Liu Xiaobo, landed in Berlin late on Tuesday night after spending years of effective house arrest. The Foreign Ministry said the poet left at her own will to seek medical treatment.
Patrick Poon, a China researcher at Amnesty International, said the visit of Premier Li Keqiang to Germany this week and the upcoming EU-China summit have a lot to do with Liu Xia’s release.
But he told RTHK's Candice Wong: "It’s not like China is accepting that they should respect human rights."
Poon said there are other widely reported cases, such as the human rights lawyer Wang Quanzhang who is being detained, but still authorities have not released them.
"But of course it’s very symbolic for Liu Xia’s case to show the hope they can get."
