Yet, despite this chronic ambiguity, we are offered Derrida's apparently un-Derridean assurance that hospitality is ethics (Derrida 1999a: 19); not just an ethics, but ethics itself (Derrida 2001: 16-7). While immensely provocative, this claim is not really unpacked nor its implications drawn out in the depth one might wish. Furthermore, Derrida links this notion of hospitality as ethics to an understanding of power and control as sovereign mastery, a link which is potentially very limiting for how we use and understand hospitality in a global context. This article seeks to reaffirm the importance of hospitality for discussions of international ethics, but also to suggest a way in which we can push beyond the limitations imposed by Derrida.When we interrogate the implications of hospitality as ethics, we reveal a constitutive link between ethics, power and space within practices of hospitality. As it operates to form relations between self and other, inside and outside, inclusion and exclusion, those distinctions also need to be policed, managed and controlled, even after the threshold of the home is crossed. Such management and administration of hospitality takes us beyond sovereign mastery and its statist implications. Furthermore, the acts of welcoming and controlling work to produce the home itself, its spatiality (internal and external borders) and its affectivity (feelings of belonging and nonbelonging). I argue that if we are to retain Derrida's aim of transforming and improving the practice of international hospitality (2001: 22-3), we must pay attention to the ways that his assumptions are being disrupted.The article begins by exploring what it means to say that ethics is hospitality in an international context, arguing that actual acts of hospitality can be conceived as spatial and affective relational practices. The second section outlines the implications of this claim for the power relations operating in practices of hospitality, especially those that manage the space of the home and (re)produce its affective dimensions. The third section examines what an investigation of spaces created as homes through everyday practices of international hospitality might look like, focusing on refugee camps. These are non-state, non-sovereign, extra-territorial spaces that are produced through the practice of a hospitality towards those most in need, thereby disrupting the assumptions of Derrida and international ethics regarding who/what can be a host, a home and
