Zhou Yongkang, former member of the Politburo Standing Committee of the Chinese Security and former minister during the tenure of former president, Hu Jintao, is under investigation for corruption, as announced on Tuesday the Chinese government official sources collected by the state news agency Xinhua.

Until now, a member of the Politburo Standing Committee of the Communist Party in China granted absolute immunity. The law never punished those who have handled the wires and key connections for running the country. But this custom seems to be changing with the coming to power last year President Xi Jinping. One of the pillars of its political project is the fight against corruption, in a campaign that aims inclement load even with the high command. With this cleaning strategy to regain the confidence of the people in their government.

In a show of power to Xi, clean reached its peak with the announcement of the investigation of Zhou Yongkang, one of the nine members of the Standing Committee during the Hu Jintao government, from 2002 to 2012 – for “serious disciplinary violations”, euphemism in Chinese political jargon usually refers cases of corruption. This move is unprecedented in the history of the PRC. Other senior leaders were convicted before for political reasons, as happened with the Gang of Four for abuse of power during the Cultural Revolution in 1976; counter or attitudes, as happened with Zhao Ziyang, shooting Communist Party General Secretary, for his sympathies toward Tiananmen Square protests in 1989.

The movement shows the eyes of analysts Xi Jinping and his right hand in this effort, Wang Qishan, Secretary of the Central Commission for Discipline Inspection of the Communist Party, are determined to reach the so-called “tigers”, senior officials of the Party. ” The investigation into Zhou Yongkang, one of the most powerful men in China, implies that Xi is serious,” said Wang Yuhua, professor of Chinese politics at the University of Pennsylvania: “Before there was skepticism, since in previous leaderships were launched initiatives reached only lower leaders. “

The arrival in power of Xi was preceded in 2012 by the scandal of Bo Xilai, former member of the Politburo and emerging political figure, who was convicted for abuse of power after his wife was accused of murder, and several of his subordinates for disciplinary violations.

Zhou Yongkang was just Bo promoter within the Party. Research what splashed so that lost prominence in October and disappeared from the public eye, prompting rumors of a possible house arrest in late 2013.

However, positions he has held in his political career Zhou is where one can trace the reasons to understand his disgrace. ” Zhou Yongkang was extremely powerful in two Chinese industries: oil and legal” explains Professor Wang Yuhua. “One is the most profitable industry in China with a monopoly on the production and sale of oil and gas, and the second is vital, because it controls the security forces. To consolidate power in the country, the new leaders should be in control of these areas, ” he says. And Zhou managed to get Money seems to match their portfolios of work.

Fortune documented the Zhou family thanks to its oil connections exceed 112 million euros. The investigation against the former leader has already led to the arrest of his wife, his brother, his son and daughter. Also officials and nearby provincial leaders and the criminalization of money laundering oilmen.
