However, it is worth noting that Article 1 of the United Nations Convention on the Rights of the Child defines a "child" as a person who is not older than 18 years of age.
The discrepancy in definitions between the two was an intentional arrangement, as the United Nations hoped that the Convention on the Rights of the Child would provide protection and protection of the rights of as many children as possible in the same age group, and because there was no United Nations Convention on the Rights of Youth at that time that was similar to the Convention on the Rights of the Child.
