World Pandemic Control in International Law: Through a Transboundary Harm Perspective

The current pandemic response system under the International Health Regulations has been considered unsatisfactory in controlling world pandemic outbreaks. Opinions are voiced that a legal evolution incorporating other sources of international law is imperative to meet the system’s primary deficiency: the uneven degree of State compliance with the ‘core capacity’ requirements. Against this background, this paper aims to examine the potential application of transboundary harm rules in world pandemic prevention, where existing treaty obligations are insufficient or ineffective in addressing future obstacles. By comparing their conceptual characters and legal elements, this paper seeks to reveal the inherent link between the two domains, which may further demonstrate an existing manifestation of transboundary harm rules as emerging customary international law in current pandemic prevention practice. Based on the structure of transboundary harm rules, this paper aims to provide an innovative legal framework that justifies the differentiated standards among States with uneven capacity and underlines the obligation of cooperation. Such a framework is designed to improve the level of States’ prevention and response towards future global health emergencies raised by world pandemics. Moreover, it hopes to provide practical ideas for formulating the new international instrument on pandemic prevention, which is currently being drafted by the Member States of the World Health Organization.
