There have been increasing and stronger calls for greater integration of many Asian economies, either within the confines of ASEAN or on a more geo-economically strategic scale that would include major Asian jurisdictions like China, Japan, and Korea. A number of key personalities within the regional legal fraternity have advanced views that such integration ought to occur through the harmonization of legal rules, arguing amongst others that in so doing uncertainty and other transaction costs would be reduced and commercial confidence within the region concomitantly increased. That commercial law has come under the lens as a particularly suitable candidate for harmonization is, in a sense, unsurprising. It is for one ostensibly seen as a technical and relatively uncontroversial area of law, as opposed, for instance, to public law. For another, or probably for that precise reason, this area has been the historical choice for attempts at harmonizing substantive law – think of the CISG, the UCC in the United States or the recently proposed CESL in the European Union. This edited volume brings together eminent and promising scholars and practitioners to investigate what convergence and divergence means in their respective fields and for Asia.
