The aim of this study is to examine opinions discussed on the structure of the PA between MOMAF, Pusan city and Inchon city by analysing and reviewing the reports and debates with the Promotion Committee. In addition, this paper is to find out the reasons why they have different views and opinions over the establishment of PA and to analyze how such conflicting opinions will influence on future operation in the PA. On the basis of the above research, this study suggests a more rational proposal to establish the PA not from the result of the negotiation between the interested parties, which have involved in the process of establishment of the PA, but from the viewpoint of principles.
