The current era of emergencies, which includes climate change, environmental challenges, armed conflicts, and health crises, has a profound impact on foreign direct investment (FDI). A panel held on 27 September 2022 as part of the second edition of the World Arbitration Update (WAU) engaged with the effect of such global emergencies on international investment law (IIL) by focusing on ideas related to “Balancing the Protection of Foreign Investors and States Responses in the Post-Pandemic World”, a book published by Kluwer earlier this year and co-edited by Dr. Yulia Levashova and Dr. Pascale Accaoui Lorfing (also authors of book chapters). The book provides a comprehensive understanding of the impact of Covid-19 crisis on the IIL regime from both a State and an investor perspective. It draws focus to the analysis of investor rights and State defences from a multi-jurisdictional and regional standpoint, including Latin America, India, Korea, the United States and Russia. The book’s detailed examination of the effects of a pandemic on States and investors demonstrates how any crisis can alter the balance between investors’ legal protection under IIAs and the State’s regulatory authority to implement emergency measures.
