Abstract
During the COVID-19 pandemic, many port states faced difficulty when cruise vessels with COVID-19 patients tried to dock at their ports. Although they are basically not obliged to accept such vessels under international law, they cannot easily deny access because the refusal would be viewed as a lack of humanitarian consideration. On the other hand, accepting such vessels leads to the risk of exposing their own nationals to COVID-19 and incurring the financial cost of medical treatment for cruise passengers. In fact, in the cases of Diamond Princess, Costa Atlantica, and Zaandam and Rotterdam, the question of who should take on the financial burden for medical costs of crews and passengers on board these vessels was debated. The current international legal framework does not provide any answer to this question, and therefore, a new framework is needed. If the new framework allocates the economic burden to ensure the provision of tests and medical care so that an intolerably heavy burden is not imposed on port states, they will be more welcoming to cruise vessels with infected people. Such allocation could be realized by requesting that carriers provide a compulsory insurance system for medical care in a pandemic.
