The spokesman for the Norwegian Nobel Committee says the panel is very concerned over the lack of information about Liu Xiaobo, the imprisoned Chinese dissident awarded the Nobel Peace Prize last year.
Permanent Secretary Geir Lundestad says the committee hasn't received any updates about Liu's whereabouts or wellbeing since October, when the prize was announced and Liu's wife went to visit him in prison.
While several previous Nobel laureates have been prevented by their governments from collecting the prize, Lundestad called the total silence surrounding Liu "unprecedented."
Liu won the prize for his nonviolent struggle for human rights in his homeland. The award infuriated Beijing, which accused the Nobel committee of honoring a criminal.
