HANGZHOU - China's e-commerce giant Alibaba said Monday that the system it developed for the Ministry of Public Security last year had helped find more than 600 missing children in 2016.

The system called "Tuanyuan," or reunion, is a pop-up platform that has been applied to multiple websites and apps, such as AutoNavi and Alipay.

Since its launch, over 70 billion pop-ups have been released, sharing the information of 648 missing children, with 611 of them later found, said He Bin from Alibaba's security department.

"Most of the children were reported lost or had run away from home, but 4.2 percent were rescued from child traffickers," He said.

Apart from updating child lost and found information, the system also refutes fake information.

According to He, major internet companies across the country will join the network this year.
