BEIJING (Kyodo) -- China's Communist Party has decided to investigate the country's former public security chief Zhou Yongkang for suspected "serious disciplinary violation," the official news agency Xinhua said Tuesday. The 71-year-old is China's most senior politician to have been caught up in a corruption investigation in decades. Zhou was one of nine members of the Politburo Standing Committee under then President Hu Jintao.
