Responses and Reactions of Host States to Investment Treaty Law: Some Empirical Observations


While much has already been written on why states sign international investment agreements, there is a dearth of studies on the connection between such agreements and state actions in both the domestic and international arenas. What effects do international investment law and its dispute settlement mechanism have on state behaviour? Existing scholarship has so far been preoccupied with patterns of state behaviour in the international scene, such as treaty reform, thus leaving unaddressed the various patterns of state engagement with investment treaty law through changes in national laws and policies. In my current research project, I seek to critically evaluate the interplay between international investment law and host state behaviour from doctrinal, normative and empirical angles. In particular, I draw on empirical studies recently undertaken in select developing states, to expose some of the actual rather than abstractly imagined patterns of state behaviour, and to evaluate the international and domestic pressures and influences that ultimately shape state behaviour in the international investment law scene. The aim is to trace the emerging “nationally felt” responses to international investment norms and to analyse some of the factors that may hinder or facilitate the translation of such responses into international norms.
