This conclusion presents some closing thought of the key concepts covered in the preceding chapters of this book. The organization of regional free trade areas for the circulation of Arab goods; the creation of regional institutions aiming at fostering the flow of capital in the Arab world; and the movement of peoples and ideas across the topographic and ideational limits of the Arab region. Studying regionalism from a post-structural perspective is to acknowledge that there is no indisputable knowledge about what reality is; and it was from this basis that the "doomed Arab region" narrative was challenged. GCC investment in the Arab world is increasingly dependent upon conditionalities and, these belong not only to the realm of economics, but also to culture and politics. When mental representations are articulated around cumulative sets of reiterative regional discursive practices, they lead to the materialization of the region.
