This chapter examines how the facilitation of foreign direct investment (FDI) through the World Trade Organization (WTO) can contribute to fulfilling the right to development and achieving UN Sustainable Development Goals. It assesses how the WTO facilitates investment related to sustainable development in developing countries through liberalization of trade in services, restrictions on trade-related investment measures, and promotion of intellectual property rights. The study finds that reform efforts to make these WTO disciplines more conducive to sustainable development have been slow and of limited significance. The chapter also looks at how investment is facilitated through investment treaties and domestic investment legislation, highlighting the importance of domestic investment legislation for promoting investment for sustainable development, particularly for least developed countries. Finally, the chapter discusses whether and how the draft WTO Investment Facilitation for Development Agreement can most effectively achieve its objective in relation to countries most in need of development-related investment, considering the relative roles of the home and host states of FDI.

The rapid growth in investor–state dispute settlement has sparked a decades-long legitimacy crisis in the international investment regime. The upshot is that concerns over foreign investor success in arbitration proceedings, from levels of compensation to lack of arbitral diversity and independence, has prompted wide-ranging reform efforts and even calls to abolish this treaty-based system. In the context of this historical and contemporary debate, the authors describe the importance of assessing empirically the claims and counter-claims about the regime’s absence of legitimacy. The chapter begins with an overview of the different types of legitimacy (normative, sociological, legitimation) and discusses how and to what extent empirical research can contribute to assessing legitimacy claims. The different chapters of the book, which is structured largely according to legitimacy categories, are then introduced and the piece concludes with some reflections on the overall themes and way forward for empirical research.

Any assessment of the international investment regime and its legitimacy crisis requires a preliminary understanding of their important and relevant features. However, the sprawling nature of both defies most doctrinal and qualitative attempts at description. The regime is based on a decentralized network of legal instruments, different procedural mechanisms and ad hoc proceedings, while the accompanying chorus of critique and counter-critique is populated with multiple actors and interests across the world. This chapter seeks to capture this distinct and fragmented universe. First, the authors map consent to arbitration, not on a generic per signed bilateral investment treaty basis, but rather by tracking multilateral, bilateral and unilateral consents in force. Second, they provide a description and overview of the over 1,100 registered cases up to January 2020, focusing inter alia on case outcomes, rules, cases types, institution, parties, economic sector and legal basis. Third, they trace discontent with regime, charting the origin of legitimacy crisis and its maturing over time. It ends by discussing both state-led efforts at reform and the extent to which arbitrators themselves have adjusted reflexively to the backlash.

The absence of ISDS cases against China may mean that investors are deprived of adequate and effective remedies for resolving investment disputes. Based on [type of empirical research], the authors find support for the view that the procedures offered by Chinese IIAs and legislation promote dispute resolution that is mutually satisfactory among investors and closely related public officials. However, they also find a possible trade-off in the sense that such solutions might depend on and promote corruption. Against this background, they explore how ISDS could contribute to combating corruption.
