China's top anti-graft authority has concluded its annual plenary meeting in Beijing, pledging no let-up in the anti-corruption drive.

The three-day meeting has approved a work report delivered by Wang Qishan, chief of the ruling party's Central Commission for Discipline Inspection.

In a communiqué issued after the meeting, authorities used the words of "heavy-handed" and "unchanging rhythm" to describe the anti-graft effort in 2016.

The communiqué also listed achievements made last year, including intensified supervision and the capture of several international economic fugitives.

It said that the investigations of Zhou Yongkang and Ling Jihua have removed "hidden political threats" within the Communist Party and demonstrated the ruling party' resolve to strictly govern itself.

But it's been noted that problems remain.

Authorities have vowed to strengthen discipline and improve the supervision system in 2016, as well as deepen institutional reforms.

Greater efforts will be made to pursue fugitives and recover stolen assets as part of the upgraded international cooperation against corruption.

In addition, the graft-buster said it will continue its inspection work this year.
