Corrupt Chinese officials who have fled abroad are being offered reduced sentences and other incentives to give themselves up and return home, state media said on Friday, as the government continues its sweeping campaign against graft.

Beijing has long grappled with the issue of so-called "naked officials" — government workers whose husbands, wives or children are all overseas — who use foreign family connections to illegally shift assets out of China or to avoid investigation.

Some estimates put the number of Chinese officials and family members moving assets offshore at more than 1 million in the past five years.
