The law on foreign direct investment (FDI) belongs to the fastest changing legal field in international law. Investors and the host state have long left behind a relationship dominated by the host state's desire to screen and choose FDI. In the current market for FDI, both parties try to assert influence, but in the end the scarcity of FDI is the decisive factor. This book provides an in-depth study of the legal framework for the admission of FDI and presents insights into the pros and cons of various admission models. Its goal is to identify legal and policy options that serve the host state's and investor's common needs. The book is a comprehensive, easy reference handbook that is of interest to lawyers, academics and policy makers.
