Chinese billionaire banker Bao Fan, who has been missing for almost a year, has resigned from all roles at his firm, China Renaissance Holdings.

He stepped down “for health reasons and to spend more time on his family affairs,” the bank said in a statement.

Mr Bao’s unexplained disappearance in February last year shocked China’s business and investing community.

Just days later, China Renaissance said he was cooperating with authorities who were conducting an investigation.

In its latest filing, the company said co-founder, Xie Yi Jing, will assume Mr Bao’s most senior roles.
