Free trade agreements (FTAs) have been proliferating in Asia for more than a decade. International fragmentation of production and the resultant cross-border production networks have been growing for a much longer period. Although FTAs are not necessary for the formation of production networks, can they support their further growth or spread? Empirical studies have produced mixed results, presumably because the causality can run either way. Therefore, this paper employs a qualitative approach that carefully examines the characteristics of both product fragmentation trade and FTAs in Asia to ascertain possible linkages. We find the relationship to be tenuous for a number of reasons. First, most product fragmentation trade already takes place at zero or low tariffs because of the International Technology Agreement, various duty-drawback schemes, and the location of most multinationals in duty-exempt export processing zones. Second, much of fragmentation trade is unlikely to benefit from FTA tariff concessions given the inability to satisfy rules of origin because of limited value-addition. Third, almost all FTAs involving Asian countries are relatively shallow, and there are still some non-tariff barriers that affect this trade. For these reasons, national liberalization actions that deal with incumbency issues would be the best way forward.
