Chinese internet giant Tencent fired 70 people and blacklisted 13 firms last year as part of an anti-graft campaign.
Tencent will no longer work with the blacklisted companies and a few of the people who were dismissed have been reported to public security authorities.
The gaming and social media company said that cases involved bribery and embezzlement.
Over the last year, Beijing has introduced new laws in areas from data protection to anti-monopoly.
One case involved an employee at Tencent’s digital music department using his position to ask for benefits from suppliers.
In another case, a former employee who worked on film and television content took possession of props and clothes that were purchased by Tencent for filming.
Tencent shares, which are listed in Hong Kong, fell on Tuesday amid a broader slump in Asian markets.
