With China¡¦s renaissance the most important factor for its good neighborhood policy is to shape multilateral regime. In this thesis the author is attempted to use the approach of neoliberal institutionalism examining how China uses regime to carry out its national interest. Furthermore, the cooperation between China and ASEAN on regional trade agreements, confidence building measures, nontraditional security area, as well as building of East Asian Community will be discussed. In parallel with this context how China and ASEAN use regime to maintain their own interest and to prevent each other going beyond the proportional profit will be analysed.
