In Wang Qishan’s latest annual report card published over the weekend, China’s chief corruption buster cites figures like 282,000 officials punished for “discipline violations” in 2015 while pledging to sustain work this year at an “intensity and pace unchanged.”

Mr. Wang, a member of the Communist Party’s ruling Politburo Standing Committee, runs the party watchdog Central Commission for Discipline Inspection and said China’s corruption battle is a long-term strategy aimed at rejuvenating the nation, according to the text of a speech published Sunday.

“Our goals and tasks won’t change,” Mr. Wang pledged.

He said that last year 200,000 party members received light punishment, while 82,000 faced severe punishment. In many cases the term “discipline violation” indicates a suspicion of corruption but can also refer to breaking other rules, from living extravagantly to exhibiting laziness on the job.
