The Role of Sub-Regional Systems in Shaping International Investment Law-Making: The Case of the Visegrád Group

The present chapter focuses on the role of the Visegrád group (or V4, comprising Slovakia, Hungary, Poland and the Czech Republic) in international investment law-making. The chapter starts with a brief overview of the V4 group as a sub-regional system in Europe, including its modus operandi and main achievements in the field of economic cooperation. Subsequently, it turns to the regulation of foreign direct investment (FDI), both at the level of each V4 state and at EU level—with particular regard to the implication of the EU’s exclusive competence on FDI. Special attention is paid to the approach of the V4 countries towards the question of termination of intra-EU bilateral investment treaties (BITs)—including an overview of the related objections to jurisdiction that the four countries have raised over the years in investor-state arbitrations based on intra-EU BITs—and to the relationship of the V4 group with non-EU countries—especially with (selected) East Asian countries. The main question is whether—and to what extent—the V4 group as a sub-regional system has a role to play in international investment law-making. The chapter highlights the proactive and advocacy role that the V4 group has traditionally played in manifold subject-matters, including the promotion and protection of FDI, and supports the positive “soft power” the V4 may exercise in this respect.
