  There are advantages associated with both types of inquiries. An important advantage of asking what states owe one another is that much international law presupposes the states system and requires states to perform various actions to promote justice. In this way, responsibilities often appear to be clearly allocated to particular parties thus making it quite precise who ought to do what in our actual world. One advantage of global justice inquiries is that we are not forced to take states as a fixed constraint and we can therefore consider a range of relevant relationships, capacities and roles that also structure our interactions and might be relevant to how we ought to conceptualize global responsibilities. While asking about what individuals owe each other may well have implications for states and their obligations, a range of other agents and institutions may also have relevant justice obligations. These responsibilities can become more visible when we explore what individuals owe each other. The two approaches have different strengths and can complement each other, but in contemporary debate they are often taken as rivals competing to provide the most plausible framework.
