Civil Affairs and Public Security Departments have been urged to take comprehensive steps to help children who are begging on the nation's streets and are often abused. Premier Wen Jiabao said during his online chat with netizens, China Daily reported.

Wen said he has paid close attention to the ongoing micro blog campaign that calls on concerned netizens to post photos of children begging on the streets in the hope that police will rescue them and return them to their families. There are many reasons why children turn to begging, including poverty and family problems. Joint efforts will help end the problem.

His remarks were welcomed by Yu Jianrong, a professor from the Chinese Academy of Social Sciences, who starts the online campaign to crack down on child begging.

The All-China Women's Federation (ACWF) also released a statement encouraging people to contact the police if they find any suspect who abuses, or forces juveniles to beg on the streets. People can either call 110 and or dial 12338 and connect with a hotline set up by the ACWF. The statement was reported by Xinhua News Agency.
