Experience from other regional cooperation initiatives like GMS shows that development of economic connectivity corridors is a challenging task that requires time, resource mobilization and political commitment. Southeast Asia has long recognized the need for greater regional integration and cooperation, and this is manifested in ASEAN activities. These should help provide a broader framework and facilitate political commitment to development of IMT-GT regional connectivity. This chapter also briefly describes initiatives at national level for developing infrastructure that has regional dimensions. These infrastructure plans when implemented will contribute to enhancing IMT-GT connectivity. Finally, based on the initial assessments of this preliminary study, the chapter also identifies specific infrastructure projects that need to be prioritized in future plans of stakeholders, as well as reiterating areas where further studies are needed in order to empirically and analytically inform policy dialog on future development of IMT-GT economic connectivity corridors.
