After nearly two years of silence, a controversial mainland tycoon has resurfaced and alleged that members of the Communist Party’s inner circle were among the backers of a fallen business rival. Guo Wengui, the controlling shareholder in Beijing Zenith Holdings and Beijing Pangu Investment, appeared in a video interview last Thursday on Mingjing, an overseas Chinese political rumours website. Guo said in the interview that Li You, former CEO of technology conglomerate Founder Group, had powerful “backers” in the party’s Politburo Standing Committee. He vowed to name some of these backers later. Caixin Media vows to sue Chinese tycoon Guo Wengui and Hong Kong newspapers for libel Guo also made allegations against deputy national police chief Fu Zhenghua, who headed the special unit that investigated disgraced security tsar Zhou Yongkang. But Guo did not provide evidence to back up his claims, which cannot be independently verified. In bidding for a landmark property project near Beijing’s Olympics stadium in 2006, Guo toppled Liu Zhihua, a former Beijing vice mayor, with a sex tape of Liu. The mainland magazine Caixin reported Guo obtained the sex tape with the help of Ma Jian, a former deputy minister with China’s state security ministry who is now in jail. Guo said in the interview that he submitted the sex tape of Liu to China’s disciplinary watchdog, but he didn’t specify how he got the tape. His reappearance came just a day before Xiao Jianhua, a mainland billionaire believed to have ties to party elites, was reportedly captured by mainland security agents in Hong Kong. Li was sentenced to four-and-a-half years in jail for insider trading and other offences in November. He and several other top executives at state-owned Founder were arrested in 2014 in the fallout of a spat with Guo over the board composition of the group’s securities house.

He also accused Li of hiding and laundering money for leaders in the Politburo and its Standing Committee. Li is known to have ties to former presidential aide Ling Jihua, who is now behind bars for life for corruption. However, Guo said Ling and his wife Gu Liping were only “small backers” of Li. Fu, who was once considered a rising star in the police force, was removed last August from his post at the party’s Central Politics and Law Commission. Guo also said his employees on the mainland had been seized by a special investigation team and interrogated using “inhumane” methods.

At the time, Guo rejected accusations that he went into hiding overseas from graft-busters after Ma’s downfall, claiming he was in New York for medical treatment and would soon return to China to clear his name. But since then, Guo’s whereabouts have remained a mystery. He did not respond to a request for comment on Tuesday.
