Beyond the border: diplomacy, cooperation and human rights in child migration

This article analyzes the situation of unaccompanied children in migration at the United States-Mexico border between 2019 and 2025 through the lenses of humanitarian diplomacy, international cooperation and human rights. Using a qualitative critical-interpretative methodology, it examines bilateral diplomatic frameworks, institutional actors and migration governance mechanisms affecting child protection. The analysis draws on international legal instruments, public policies and reports issued by governmental and non-governmental organizations. The findings reveal persistent tensions between humanitarian discourse and migration control practices, showing how border security priorities frequently override the best interests of the child. Structural protection gaps derived from institutional fragmentation and limited coordination are identified. The article contributes a critical framework for rethinking migration governance from a rights-based perspective centered on dignity, justice and child participation. The study is limited by its reliance on secondary sources.
