The growing importance of international investment law, fuelled by the processes of globalisation and the search for natural resources, and fostered by the ease of cross-border financial flows, has given rise to a huge expansion in the incidence of new investment treaties and, consequently, disputes. The complexity of this area and the enormous sums of investment involved mean that the agreements and treaties themselves are highly evolved, while the disputes arising are often hugely intricate and intractable. No area of international law is more in need of the careful and balanced attention of scholars. Anyone interested in international investment law will appreciate this comprehensive, thoughtful and detailed exploration of this area.
