Rescuing people in distress at sea is a duty. However, does international law require a coastal State to open its ports or territorial sea to foreign ships involved in the rescue? The question is not new, especially in the context of migration flows from Africa. Mostly, however, the analysis has been focused on the conduct of individual States, as opposed to the community of States.
Paolo Busco addresses these questions both from the perspective of direct obligations and obligations of cooperation in law of the sea, discussing solidarity in the management of migratory flows.
