Practice Relating to Rule 137. Participation of Child Soldiers in Hostilities
In 2004, in its second periodic report to the Committee on the Rights of the Child, Thailand stated:
There is no stipulation in law for the age of participation in hostilities, but according to Thai law, the minimum age for conscription into the armed forces is 21 years. Those who have completed their third year of military training in the reserves – the majority of whom are over 18 years of age – will be allowed to enter the military reserve corps.

3. For the purposes of the implementation of the Optional Protocol, children under the consideration of Thailand include both Thai and non-Thai children, child immigrants and displaced children fleeing armed conflict, including those in the temporary shelters. Thailand seeks to ensure that all children in Thailand below the age of 18 years will not take a direct part in armed conflict and be forcibly recruited into the Thai armed forces or groups.
II. General principle
