This book is a thought-provoking and authoritative text on this fast moving field of international law.

Increasing international investment, the proliferation of international investment agreements, domestic legislation, and investor-State contracts have contributed to the development of a new field of international law that defines obligations between host states and foreign investors with investor-State dispute settlement. This involves not only vast sums, but also a panoply of rights, duties, and shifting objectives at the juncture of national and international law and policy. This engaging Research Handbook provides an authoritative account of these diverse investment law issues.

The book focuses on some of the most pressing issues in international investment law in Asia, such as the role of developing countries, the rebalancing between the investors’ rights protection and the host states’ right to regulate, the ISDS reform, among others. The book investigates these issues by looking into the bilateral investment treaties and investment arbitration cases in the region. The readers will benefit from this book’s rich content and wide coverage. For instance, the readers would learn more about Asian states’ Bilateral Investment Treaty law and practice and their standing on international investment law. The book provides a fresh angle to most readers who may be more exposed to the Western perspective on the topic, providing a more complete picture to add to the readers’ understanding of international investment law and in particular its evolution and future possibilities.

This book critically analyses how arbitration cases, institutional rules and emerging codes of conduct in the international arbitration sector​ have ​dealt with​ a series of​ key​ arbitrator duties to date. In addition, it ​offers a range of feasible and well-grounded proposals regarding ​investment arbitrators’ duties in the future. The following aspects are examined in depth: the duty of disclosure the duty to investigate​ the duty of diligence​ and integrity​, which in turn may be divided into temporal availability, a non-delegation of responsibilities, and adhering to appropriate behaviour​ the duty of confidentiality, and other duties such as monitoring arbitration costs, or continuous training​. Investment arbitration is currently undergoing sweeping changes. The EU proposal to create a Multilateral Investment Court incorporates a number of ground-breaking developments with regard to arbitrators. Whether this new model of permanent “members of the court” will ever become a reality, or whether the classical ex-parte arbitrator system will manage to retain its dominance in the investment arbitration milieu, this book is based on the assumption that there is a current need to re-examine and rethink the main duties of investment arbitrators. Apart from being the first monograph to analyse these​ duties in detail, the book will spark a crucial debate among international scholars and practitioners. It is essential to identify arbitrators’ duties and find consensus on how they should be reshaped in the near future, so that these central figures in investment arbitration can reinforce the legitimacy of a system that is currently in crisis.

This book offers an up-to-date, scholarly overview of the law of foreign investment, incorporating a thorough and succinct analysis of the principles and standards of treatment available to foreign investors in international law. It is authoritative and multi-layered, offering an analysis of the key issues and an insightful assessment of recent trends in the case-law, from both developed and developing country perspectives. A major feature of the book is that it deals with the tension between the law of foreign investment and other competing principles of international law. In doing so, it proposes ways of achieving a balance between these principles and the need to protect the legitimate rights and expectations of foreign investors on the one hand, and the need not to unduly restrict the right of host governments to implement their public policy, including the protection of the environment and human rights, and the promotion of social and economic justice within the host country, on the other. Since the first edition was published a number of landmark decisions have been produced by various international investment tribunals, calling for an update in what is a fast growing and rapidly changing investment environment. In addition, scholars and other actors, both non-governmental and inter-governmental, have responded to the agenda set by the first edition of this book; thus the second edition also reflects on the work of some of these major actors in the field. This is perhaps the first book of its type authored by an international lawyer who has taught, researched and advised in both the developed and developing world over the past 25 years. The wealth of experience he brings to the task enables him to develop unique insights into the interplay between the law, economics and politics of foreign investment, making this book essential reading for students, scholars, practitioners and diplomats interested in the contemporary law of foreign investment.

In a context of neoliberal globalization, have the processes of elaboration and implementation of foreign investors' responsibilities by intergovernmental organizations reached the realm of legality? Using an analytical framework and a methodology that combines international law with international relations, this book provides a twofold answer to this question. First, it demonstrates that the normative integration of foreign investors' responsibilities in international investment law is fragmented and consistent with the interests of the most powerful actors. Second, while using the interactional theory of international law to assess the normative character of several international instruments elaborated and implemented by intergovernmental organizations, it highlights the sense of obligation that each instrument generates. The analysis demonstrates that such a codification process is marked by relations of power and has resulted in several social norms, with relatively few legal norms.
