Ji was found to have seriously violated political discipline and rules,transfered money and property related to the case, and resisted the investigation against him, according to a statement released by the CPC Central Commission for Discipline Inspection (CCDI).
The CCDI investigation found that Ji violated organizational rules and failed to report his personal matters.
He was also found to have taken bribes, purchased houses at below-market prices, invested in unlisted companies while breaking rules, embezzled public funds and property, and sought benefits for other people.
As a senior official of the CPC, he has lost his faith and severely violated the Party discipline and law, said the statement.
Ji's illegal gains will be confiscated and his case transferred to the judiciary, it added.
The CCDI announced the investigation into Ji for "severe disciplinary violations" in January.
