This important book examines the development of soft law instruments in international investment law and the feasibility of a 'codification' of the present state of this field of international economic law. It draws together the views of international experts on the use of soft law in international law generally and in discrete fields such as WTO, commercial, and environmental law. The book assesses whether investment law has sufficiently coalesced over the last 50 years to be 'codified' and focuses particularly on topical issues such as most-favored-nation treatment and expropriation. This timely book will appeal to academics interested in the development of international law and legal theory, to those working in investment law, government investment treaty negotiators and arbitration practitioners.
