International Investment Law

The updated edition of this acclaimed book offers a critical overview of the law of foreign investment, incorporating a thorough 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 restrict unduly the right of host governments to implement their public policy on the other, including the protection of the environment and human rights, and the promotion of social and economic justice within the host country.

Many of the pioneering ideas that were advanced in the 1st edition of this book have been taken up by governments and international organisations in their attempts to reform the investor-State dispute settlement mechanism and strike a balance between different competing principles in developing international investment law. Accordingly, this 5th edition captures the essence of the multiple reform processes, examines the recent trends in international investment law and arbitration, and highlights the major recent changes that have taken place in this area of law.
