Chen Xitong's falling out with former president Jiang Zemin - which led to Chen's imprisonment 16 years ago - has followed the disgraced Beijing mayor to his grave, sources say.
Chen Xitong was the mayor of Beijing between 1983 and 1993. He was widely believed to be one of the key decision-makers within the Communist Party of China responsible for the bloody crackdown of a student-led democracy movement in Beijing in 1989, which led to the death of at least hundreds of students. Chen was stripped of his party membership in 1997 in a corruption investigation and was sentenced to 16 years in jail in 1998. He died of cancer on June 2, 2013.
