China's Ministry of Public Security announced Saturday that 611 missing children were found last year, following the launch of an app in May.

During the period, 648 updates on missing children were posted. Of the 611, 27 had been abducted and 358 had run away from home, according to the ministry.

A new version of the platform that went live in November has expanded its reach through cooperation with other popular mobile apps, such as Amap,Taobao, Baidu, QQ and Didi Chuxing.

Users near where a child disappears receive push notifications, including photos and descriptions. The scope of these push notifications will be expanded over time.
