Does regionalism lead to more global trade integration in East Asia?

Since early 1999, global trade liberalization has been sidelined as regional trade agreements (RTA) have become the preferred choice in East Asia. Does this shift suggest that global trade and welfare levels will be raised? In contrast to unilateral trade liberalization, RTAs may well cause both 'trade creation' and 'trade diversion,' so that their net effect on global trade and welfare becomes ambiguous. It is conjectured that RTAs among "natural trading partners" are more likely to be trade-creating, and less likely to divert trade from non-member countries, in which case welfare will improve. We find that if an RTA involves geographically proximate countries (measured either by distance or border), trade significantly increases among them. At the same time, geographical proximity also contributes to increasing trade between members and the rest of the world. We examine how existing or proposed East Asian trading blocs affect intra-bloc and extra-bloc trade and thereby global trade. We find that the East Asian RTAs are likely to create more trade among members without diverting trade from non-members.
