China's immigration management authorities cracked more than 35,000 cases in a campaign targeting crimes undermining border management, the National Immigration Administration said on Thursday.

They captured more than 79,000 suspects and dismantled 906 criminal organizations, the NIA said, disclosing 10 major cases cracked during the campaign.

The disclosed cases were discovered and handled by immigration inspection authorities in a number of regions, including Guangxi, Yunnan, Jiangsu, Zhejiang, Guangdong and Fujian.

One of the cases was jointly cracked by the general station of exit-entry frontier inspection and the immigration administration of the Guangxi Zhuang autonomous region, where Chinese and foreign human smugglers smuggled Chinese people out of the country via maritime routes and let them engage in illegal activities abroad, the NIA said.

Another case was jointly cracked by the general station of exit-entry frontier inspection of Yunnan province and the immigration administration of Jiangsu province, where the authorities dismantled a group smuggling people from neighboring countries to China to work and get married.
