The project binds the government to ensure 300,000 kuna for the project which UNICEF has been implementing in 119 schools.
Svensson said that the project represented a new method in the fight against school violence and that today's agreement would improve relations between the Croatian government and UNICEF.
She added that other countries were interested in the Croatian model of fighting school violence.
Kosor said that 100,000 children were exposed to violence by other children every day and that 20 percent of children suffered violence two to three times during their childhood.
She thanked UNICEF for everything it had done for Croatian children, especially during the war, and expressed satisfaction with the fact that the agreement was signed during Children's Week in Croatia.
UNICEF needs two million kuna to implement the project in 119 schools. So far citizens have donated 1.4 million.
Asked about the latest Amnesty International report on Croatia which mentions segregation of Romani children in Medjimurje, Kosor said that since her taking up office as Deputy Prime Minister and chairperson of the Commission for Roma a lot had been done for the Romani community and that the government would continue working to improve their living conditions.
