It was the first time for Chinese police to bring back so many suspects from an Oceanian country.
Xinhua newsagency reports the suspects are accused in more than 50 cases involving over 6 million yuan (892,000 U.S. dollars).
On Sept. 22, 2016, one of the victims in northeast China's Jilin Province was swindled out of 1.3 million yuan and committed suicide, which triggered large-scale investigations at provincial and state levels.
