China's military must learn from the glorious, uncorrupt example of its revolutionary forebears and thoroughly banish the deep-rooted, pernicious influence of the army's worst corruption scandal in decades, President Xi Jinping has told officers.

Xi, who heads the military, has made weeding out corruption in the armed forces a top goal. Several senior officers have been felled, including Xu Caihou, one of China's most senior former military officers. Xu died of cancer in March.

Meeting soldiers in the northeastern city of Chang-chun, Xi said there can be no ambiguity when it comes to fighting graft.
