'The concern about increasing fragmentation of international law as a consequence of the proliferation of international courts and tribunals has gradually shifted to a more positive expectation about cross-fertilization between different legal areas. What we now need is empirical studies about how the interaction works. Michelle Zang's comprehensive study in the fields of trade and investment through the key concept of ''engagement'' between the relevant courts and tribunals contributes to fill this gap and is highly welcome!'--Geir Ulfstein, University of Oslo, Norway'Zang's book makes an incisive foray into international economic law where numerous bilateral, regional and multilateral judiciaries are active and highlights the various paths that allow for judicial coordination. Even if one cannot deny the existence of incoherence or conflict, the book makes the point that the engagement process of courts and tribunals is healthy and leads more often towards coordination. A welcome positive assessment at a time when the international judicial function is under severe attack.'--Laurence Boisson de Chazournes, University of Geneva, Switzerland'A very important addition to the literature on the fragmentation of the international economic legal order and to that of judicial dialog across jurisdictions.'--J.H.H. Weiler, New York University, US
