Refugee Problems in Africa adopted a regional treaty based on the Convention, adding to the definition of refugee as: Any person compelled to leave his/her country owing to external aggression, occupation, foreign domination or events seriously disturbing public order in either part or the whole of his country of origin or nationality. In 1984, a group of Latin-American governments adopted the Cartagena Declaration, which, like the OAU Convention, added more objectivity based on significant consideration to the 1951 Convention.

In 1989, however, the UN signed an additional treaty, the Convention on the Rights of the Child (CRC), which defined the rights of children and bound its signatories to upholding those rights by international law. Although the CRC was not specific to the rights of refugee minors, it was used as the legal blueprint for handling refugee minor cases, where a minor was defined as any person under the age of 18. In particular, it extends the protection of refugee children by allowing participating nations the capacity
