How far has constitution-making in East Asian countries been influenced by the international law (and international society)? Many Asian countries established independence and stipulated their own constitutions for the first time after World War II. Therefore constitution-making was a new experience. It is not surprising that they overtly or covertly sought international or foreign aid. This phenomenon results in the adoption of certain characteristic clauses that pay respect to the international law and especially human rights treaties. This chapter examines this phenomenon and also reviews the direct and indirect applicability of international law in East Asian domestic legal orders.
