Chinese dissident and peace prize laureate Liu Xiaobo and his wife are seen on a monitor as workers clean the walls at an exhibition at the Nobel Peace Center in Oslo, December 9, 2010. With the guest of honor stuck in a Chinese prison, this year's Nobel Peace Prize ceremony will center around an empty chair, as its celebration of dissident Liu Xiaobo continues to split the global community and infuriate Beijing. The head of the Norwegian Nobel Committee said he was surprised at the level of international support for jailed Chinese dissident and peace prize laureate Liu Xiaobo despite pressure from Beijing.
