A Preferential Trade Area in Northeast Asia Prospects and Problems

This article offers an economic analysis of the main policy issues surrounding the proposed preferential trade area (PTA) between Japan, China, and South Korea. This initial assessment is done within the normative framework of customs union theory. Already, intra-regional trade between the three countries constitutes a high proportion of their total trade and is, in fact, cited as one of the main reasons for the PTA. As a consequence, trade creation following the PTA may not result in much new trade. However, it is expected that the PTA would lead to a vigorous growth of intra-industry trade, particularly in manufactured goods and components. Possibilities of trade diversion are real, but not insurmountable if the resulting preference structure is designed with a view to minimize disruption of trade with the rest-of-the-world.
