Washington: The US has reissued its call for China to free jailed dissident and democracy activist Liu Xiaobo who won last year`s Nobel Peace Prize.
State Department spokeswoman Victoria Nuland also urged Beijing to stop harassing Liu`s wife Liu Xia, who has been held under virtual house arrest since he won the prize last October.
Nuland told a news conference on Friday that China has an international responsibility to uphold human rights and the US raises Liu Xiaobo`s case every time it discusses the issue with Beijing.
Liu co-authored a manifesto in 2008 calling for an end to single-party rule in China, and was detained later that year. His call for peaceful political change earned him an 11-year jail sentence on a charge of "inciting subversion of state power”.
