Chinese President Xi Jinping has declared an “overwhelming victory” in his fight against graft within the ruling Chinese Communist Party, while still vowing that the campaign to weed out deep-seated corruption will continue, state media reported.

Xi has pledged to wage war on graft until corruption of all kinds has been expunged at all levels of the Communist Party, from high-level “tigers” to low-level “flies”.

He proclaimed in October 2017┬áduring a twice-a-decade meeting of the top party leadership that his fight against graft had achieved “overwhelming momentum”.

However, Xi announced at a meeting of the party’s Politburo on Friday (Dec 14) that the fight had now obtained an “overwhelming victory”, state broadcaster CCTV reported.

The shift from “momentum” to “victory” reflects an important judgment from the party leadership, CCTV said.

China’s powerful graft watchdogs handled 464,000 cases and punished 406,000 people in the first nine months of 2018.

“We must forcefully reduce the number of cases and effectively stop them from growing,” the Politburo said, according to CCTV.

Xi said efforts to overhaul China’s extensive anti-graft architecture must continue to modernise the systems of oversight for party members and state employees.

China’s new National Supervisory Commission was formally established in March, extending the graft fight to all state employees and giving legal backing to the party’s controversial internal investigation and detention techniques.

Some Chinese academics have voiced concerns that the reforms will roll back years of work by legal reformers to protect the rights of suspects during investigations.
