International investment law has often been seen as an obstacle to sustainable development. While the connections between investment and development are plain, for a long time there has been relatively little scholarship exploring them. Combining critical reflection and detailed analysis, this book addresses the relationship between contemporary investment law and development. The book is organized around two competing visions of investment and development - as working either harmoniously or in conflict with one another. The expert contributors reflect on both of these views and analyse the social dimensions of development and its impact on investment law. Coverage includes in-depth discussion on such issues as human rights, poverty reduction, labor standards, and indigenous peoples. Students and scholars of international investment law will benefit from the informed analysis of the links between investment and development. This book will also be of use to practitioners and experts of development law who are looking for an up-to-date perspective of the field.
