This book provides a fresh perspective on resolving sovereign debt disputes within the investor-state mediation framework. In response to the limitations of traditional approaches to adjudicating public debt issues and the resulting gaps in international law concerning sovereign defaults, creditors have increasingly turned to investor-state treaty arbitrations to recover unpaid debts. However, this shift has raised numerous criticisms and concerns. Accordingly, this book explores the uncharted territory of utilizing mediation as a means to settle sovereign debt claims. It sheds light on the distinctive characteristics of mediation as a process, setting it apart from judicial litigation and private arbitration, and emphasizing the unique outcomes it can generate. The central argument of this book is that mediation should be seriously considered as a viable option for resolving sovereign debt disputes. Not only does it offer a more cost-effective and expeditious approach, but it also has the potential to facilitate economic recovery and sustain continued investment.
