Graft fight can inspire other countries

The Communist Party of China has placed former public security chief Zhou Yongkang under investigation for suspected "serious disciplinary violation", a term that usually refers to corruption. But what does Zhou's fall mean?

Before his last post, Zhou had a long career in the oil industry. In 1996, he became the chief of petro-behemoth China National Petroleum Corporation and soon the Party secretary of Sichuan province. From 2002 to 2007, he was the minister of Public Security. In 2007, he became a member of the 17th Political Bureau Standing Committee of the CPC Central Committee. Thanks to his public mandate, Zhou is said to have overseen the expansion of the country's public security sector.

About a year ago, the central government launched an investigation into Zhou as part of a wider anti-corruption campaign following the trial of Bo Xilai, former Party secretary of Chongqing municipality, who was found guilty of corruption in September 2013.
