Several dozen Chinese Communist Party (CCP) officials have been under investigation since July, following a campaign to “cleanse” the Party’s “political and legal institutions.”

The purge was instigated by one of the closest allies of leader Xi Jinping, who proposed “turning the blade inward and scraping the poison from the bone,” in order to obtain tighter control and strengthen the leader’s power, analysts said, according to the Aug. 18 Wall Street Journal (WSJ).

The highest-ranking official among those under investigation is Shanghai Police Chief Gong Daogan, in addition to other cadres previously awarded for their good performance.

The aim of the campaign would be to leave in their posts police officers, prosecutors, and judges “absolutely loyal, absolutely pure and absolutely reliable,” in terms of the investigators of the CCP.

“Xi is especially dependent on this coercive state apparatus, but he also distrusts it,” said Wu Qiang, a Chinese political researcher and former professor at Tsinghua University in Beijing, according to WSJ.

The purge’s manager, Chen Yixin, would have compared it to the Yan’an Rectification Movement, executed between 1942 and 1945, one of the bloodiest in the history of the CCP to increase the powers of the dictator Mao Zedong.

For some observers, the campaign would demonstrate the persistent corruption in the criminal justice system used by the CCP.

For economist Sheng Hong, the heads of the CCP “do not recognize that corruption is an institutional problem.”

Chen Yixin’s “cleanup” campaign was also reported by Bitter Winter, which noted that recent protests in Belarus, a close CCP ally, had raised concerns within the CCP and it took action.

On the one hand, they lied by publishing that the people supported Lukashenko, both nationally and internationally, activating their troll army on social networks for the purpose.

On the other hand, they intensified their propaganda about the “need to obey” the CCP unconditionally and without criticism.

It seems that Xi is preventing the consequences of the economic disaster caused by the CCP Virus, the increasing frictions with the United States and other countries, and the eventual risk of social unrest.

Jonathan Cheng, China’s WSJ affairs officer, reiterated the information in one of his tweets.

“A senior ally of Xi Jinping called for a Mao-style purge of China’s domestic-security apparatus last month, saying it was time to “turn the blade inwards and scrape the poison off the bone.” The cleansing commenced swiftly,” Cheng wrote.

The CCP is also “the most sophisticated regime” in its use of the internet and technology applied to censorship and propaganda, with the aim of suppressing, controlling, and distorting information, said Rory Truex, assistant professor of politics and international affairs at Princeton University.

Truex also said the CCP has identified the threats it faces and how to counter them.

“But there is some evidence that that may have changed under Xi Jinping, and that some of the things that really made the Chinese Communist Party strong under his government may be eroding,” Truex added according to the Australian media ABC.
