ABSTRACT
This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book presents the Mekong region, in which state strategies are entangled and complex, can also be considered as a sub-region with such a nature. It shows that the easterly expanding Euroregion is rejecting regional autonomous movement and witnessing interstate conflict among Russia, Ukraine, and Poland. The book demonstrates that the expansion of normative politics by the European Union (EU) as a regional organization is implied in the formation of a sub-region, through which the EU is encouraging neighboring countries to accept EU norms. It shows in the Mekong region, civil society actors are constructing a Mekong public sphere with a Mekong identity in the bottom-up direction. The book reveals in the North Sea in Europe, a sub-region has been developed, largely by local governments. It utilizes comprehensive fieldwork to shed light on changes in borders, along with the formation of sub-regions.
