ABSTRACT
Trade liberalization is an important and complex issue-albeit one governed by simple principles-and regional trade liberalization is even more so. Thus in no sense can a single paper claim to give definitive answers about whether and, if so, how and with whom regional preferential integration should be pursued. I have therefore set myself a less ambitious goal of discussing not regionalism among developing countries, but rather how we might go about making such an assessment. I do not claim to be comprehensive, but rather to focus on some of the less obvious and more recent aspects of the assessment of regionalism.
