There are increasing concerns about the whereabouts of missing dissident Gao  Zhisheng. The case is unusual because the Chinese authorities have refusedto divulge Gao’s whereabouts. Gao has vanished without  legal explanation, normally even in the most politicized cases, the Chinese authorities  comply with their own criminal procedure laws.  The only comment came two weeks ago from Ma Zhaoxu, a Foreign Ministry spokesman, who said that Gao “is where he should be.” When asked again last Tuesday, he offered a smile and said: “Honestly speaking, I don’t know where he is. China has 1.3bn people and I can’t know all of their whereabouts.”
