According to the special representative of the UN Secretary General in South Sudan, David Shearer, the challenge ahead is to ensure that young people have the financial, practical and emotional support they need to train, find work and access new opportunities.
The UN special representative for children and the armed conflict, Virginia Gamba, called on the international community to support the reintegration of children and provide resources for this complex process.
They now have the opportunity to rebuild their lives and we cannot disappoint them, Gamba said.
All children recruited and used by the sides to the conflict should be released, handed over to civil partners for child protection and protected from all serious violations, in accordance with international agreements, she stressed.
The UN mission in South Sudan leads the project to free children and provide peacekeeping troops to escort those who establish contact and negotiate with armed groups.
It also works with key partners such as UNICEF, state and local authorities, and community groups.
At the end of 2013 the war broke out in South Sudan - the youngest country in the world - and despite repeated attempts to achieve a ceasefire, clashes between the government and opposition forces continue, which has led to the worst humanitarian crises on the planet.
