China has punished more than one million officials for corruption over the past three years, the government says, reports BBC. Another 409 people, said to be fugitives, have been detained overseas this year.
The statistics were released as top officials in the Chinese Communist Party begin a closed-door plenum in Beijing.
President Xi Jinping has led a wide-ranging anti-corruption drive. But some observers say the campaign has also been used by Mr Xi to purge political rivals, which he has denied.
The BBC’s Stephen McDonell in Beijing says the secretive plenum will discuss changes to the Communist Party rules.
However, analysts warn that some of the changes being considered could give President Xi Jinping too much power, our correspondent adds.
According to the party’s corruption watchdog, the central committee for discipline inspection, more than one million officials have been punished for corruption since 2013.
