The campaign, called "Positive, Safe and Responsible Cyber Environment," aims to reduce harmful impacts of modern technological breakthroughs and cyber risks, and induce proper usage of social media, Sodnomtsog Sukh-Ochir, head of the Youth Development Department of Ulan Bator, told Xinhua over the phone.

Under the campaign, 300 students studying information and technology were assigned to call on people to do positive things on preventing cyber crimes and using social media properly, he said.

The number of Internet users has been growing day by day in Mongolia. Two out of three people in the country with a population of over 3 million are Internet users, according to data released by the National Statistical Office.

Cyber-related cases like child sexual abuse through the Internet, creation of child pornography and online fraud have been increasing dramatically in the country in recent years.

In this connection, relevant authorities have carried out a number of measures to prevent risks of cyber crimes in recent months. The campaign is part of the efforts.

Recently, the country's National Police Agency has launched a national campaign to protect children from cyber crimes and strengthen parental control over children's social media usage.

According to the police agency, around 300 cyber crimes have been registered in the country in the first half of this year. Before 2010, the number is about 20.
