Geng He, the wife of Gao Zhisheng, a prominent Chinese dissident who disappeared in February 2009, said late Wednesday that she had not heard from her husband even though Chinese officials had told a human rights group recently that Gao had been in touch with her. Mrs Geng made her comments in a written statement after the Dui Hua Foundation said last weekend that the Chinese Embassy in Washington had told the group that Gao was working in the Xinjiang region and that he had been in touch with her.
