This essay in introduction is to the field of study, rather than to the present, itself distinguished, collection of papers. As such, it opens with a series of 'flashbacks': to the ways in which social policy, and the study of social policy, developed out of the interaction between Western welfare states (in this case Britain) and Asia Pacific. The main body of the article then charts the increasing presence of East Asian modes of welfare within comparative social policy, before going on to distinguish between the different types of approach to East Asian welfare study which have so far been adopted. Two sets of three-part criteria have been adopted for the purposes of classification: focusing first on the dimensions (single case studies of specific countries; East Asia as a region; East Asia in comparison with other parts of the world) and second on the level of issues (matters of policy; of welfare system; of welfare regime) characteristic of each study in question. The article concludes with a restatement of its purpose: not to question the adequacy of hitherto Western (notably, Esping-Andersen) approaches to the study of welfare regimes, but to demonstrate the need for a substantive extension to their scope.
