So-called “safe zones” pose an increasingly pressing threat to genuine and robust international legal protection for persons fleeing conflict. This paper aims to address the key challenges and risks of safe zones under international law and to provide some clarifications on the legal framework which must be respected by refugee-receiving States. Through assessing the intentions of preventing migration flows which underlie their creation, this paper will demonstrate that the existence of safe zones cannot be used to circumvent the obligations of refugee-receiving States under international law, specifically the right to leave and seek asylum and the prohibition of non-refoulement. This paper concludes that safe zones should only be created as an urgent response to humanitarian crises in order to ensure the immediate safety of civilians in conflict zones, and only under very strict conditions. In this respect, this paper will demonstrate that even if safe zones comply with certain minimum protective standards, because of the volatility and complexities of the conflict environment they should not and cannot act as a substitute for genuine refugee protection under international law.
