President Ma Ying-jeou again urged China Friday to release jailed human rights activist Liu Xiaobo who has been awarded the 2010 Nobel Peace Prize. Ma made the call at the presentation ceremony of the 2010 Asia Democracy and Human Rights Award held by the Taiwan Foundation for Democracy. Liu will not be able to attend the Nobel Peace Prize Award Ceremony, also scheduled for Friday, in the Norwegian capital of Oslo because he is in prison in China.
