Practice Relating to Rule 136. Recruitment of Child Soldiers
At the 27th International Conference of the Red Cross and Red Crescent in 1999, Sweden pledged “to promote the adoption of national and international standards prohibiting the military recruitment … in armed conflicts of persons under 18 years of age”. 
Sweden, Pledge made at the 27th International Conference of the Red Cross and Red Crescent, Geneva, 31 October–6 November 1999.
In 2009, in a statement before the UN Security Council on “Children and Armed Conflict”, made on behalf of Denmark, Finland, Iceland, Norway and Sweden, the permanent representative of Finland stated:
Recruitment of boys and girls to take part in hostilities is a violation of international law, and a war crime in both international and non-international armed conflicts. The (nearly) universal recognition of the prohibition on recruiting or using child soldiers must be matched by effective implementation on the domestic level. The first case before the International Criminal Court (ICC) to have proceeded to trial phase, the one against Thomas Lubanga Dyilo, is a milestone in the efforts to end impunity for the use of child soldiers. …
The Nordic countries wish to emphasize the need for all parties to relevant situations of armed conflict to present concrete, time-bound action plans with detailed descriptions on how they will end and prevent the recruitment of child soldiers …
[W]e would like to reiterate our encouragement to the SC [UN Security Council] and to the entire UN system to give children in armed conflict the attention they deserve.

In 2009, in answer to a written question in Parliament regarding women in war, Sweden’s Minister for Foreign Affairs stated:
When it comes to girls or boys forced into the roles of soldiers, international humanitarian law is clear. Recruitment and use of child soldiers are prohibited. To recruit child soldiers is a war crime according to the [1998] Statute of the International Criminal Court. For those 128 States that are bound by the [2000] Optional Protocol to the Convention on the Rights of the Child on the involvement of children in armed conflict, the age limit is set at eighteen.
