Investment treaties are said to improve the rule of law in the states which enter into them. Fearing claims, governments will internalise international investment obligations into their decision-making processes, resulting in positive spill-over effects on the rule of law. Such arguments have never been backed by empirical research.

In this talk, Professor Calamita discusses his new book with Ayelet Berman in which they test (and debunk) these assumptions through case studies of eight Asian countries, providing a typology of processes that governments have tried to use to internalise their commitments and identifying the factors that have made internalisation so difficult.
