A security guard stands next to a portrait of China's former President Jiang Zemin at an exhibition to celebrate the 90th anniversary of the founding of the Communist Party of China (CPC) in Beijing July 7, 2011. Chinese state media denied rumours on Thursday that former president Jiang had died after a Hong Kong television station said he had, sparking a wave of speculation about a leadership transition due next year. "Recent reports of some overseas media organisations about Jiang Zemin's death from illness are pure rumour," the official Xinhua news agency quoted "authoritative sources" as saying.
