Abstract
The rapid expansion of cross-border investment activities has fundamentally transformed the landscape of international economic relations, giving rise to complex disputes that challenge the adequacy of traditional adjudicatory mechanisms. This article examines institutional mediation as a distinct and increasingly significant element within the modern system for resolving investment disputes. Drawing upon a comprehensive analysis of international arbitration jurisprudence, institutional framework developments, and contemporary scholarly discourse, the study argues that institutional mediation occupies a complementary yet autonomous role alongside investor-State arbitration and domestic court proceedings. The article traces the theoretical foundations of mediation in international investment law, evaluates the institutional architecture provided by prominent bodies such as the International Centre for Settlement of Investment Disputes (ICSID), the International Chamber of Commerce (ICC), the Singapore International Mediation Centre (SIMC), and the United Nations Commission on International Trade Law (UNCITRAL), and critically assesses the legal enforceability of mediated settlement agreements under the Singapore Convention on Mediation (2019). The findings suggest that while institutional mediation offers substantial advantages in terms of cost-efficiency, confidentiality, and preservation of investor-State relationships, systemic challenges including lack of mandatory mechanisms, power asymmetries, and limited transparency continue to constrain its full integration into the investment dispute resolution ecosystem. The article concludes by proposing a hybrid dispute resolution model that leverages the complementarity between mediation and arbitration to enhance procedural justice and substantive outcomes in investment disputes.
