BEIJING – Frantic efforts to resolve the diplomatic wrangle surrounding blind Chinese dissident Chen Guangcheng continued in Beijing Thursday after he appealed for asylum following what was described as a "change of heart" over an earlier deal.

U.S. officials said they are still trying to help the lawyer, who says he fears for his family's safety, and denied he was pressured to leave the American Embassy to resettle inside China in exchange for guarantees about his future treatment.

Chen said by telephone from hospital, where he was escorted by U.S. officials and was being treated for a broken foot, that he had changed his mind about the resettlement deal after talking with his wife who spoke of recent threats made against his family.
