While countries that receive refugees have certain legal obligations to assist and protect them, the legal duties of other States to step in and help relieve this burden is less clear. Despite multiple proposals, a mechanism to systematically, equitably and predictably allocate responsibilities between States at a global level has still not been agreed. The UN's High-Level Summit on Addressing Large Movements of Refugees on 19 September 2016 held some promise in this regard, but the resulting New York Declaration was more muted than earlier drafts. This article seeks to provide a unique insight into the meaning of responsibility-sharing and international cooperation from the perspective of individual States. It does so by examining statements they have made at various UN fora over the past decade. It focuses on the two main methods of sharing responsibilities, namely the provision of financial and other assistance to host countries, and the admission of refugees. It then considers the extent to which States perceive responsibility-sharing to be a legal obligation, as opposed to a voluntary undertaking, and analyses this in light of expert opinion. Finally, it discusses the principle of common but differentiated responsibilities, a concept drawn from international environmental law, and considers whether and how it might apply in the international refugee law context.

Facilitating access to asylum and other forms of refugee protection for the millions displaced by mass atrocities in Syria and Iraq is essential to the implementation of the international norm of the Responsibility to Protect (RtoP). This responsibility, however, has been disproportionately shouldered by several states in the Middle East and Europe. This article explores the challenges associated with refugee responsibility-sharing in the context of RtoP and draws on work in climate justice and political realism to articulate a framework for integrating culpability as a key criterion in allocating states’ responsibilities to protect refugees. An empirical and normative assessment of U.S. responsibilities to protect refugees in the cases of conflict-induced displacement in Syria and Iraq outlines several potential paths of culpability. The article ultimately argues for greater attention to culpability, equity, and legitimacy within the discourse surrounding RtoP and refugee protection. The article also advocates linking the benefits of refugee responsibility-sharing with states’ national interests and highlights several such links with regard to U.S. responsibilities in Syria and Iraq.
