Overall, there is need to promote links and interface among the various sub-regions to broaden and deepen these given the larger geographical coverage and symer that can be generated among the ions. ASEAN makes available a broader regional framework in which these sub-regional programmes can carry out their work s may ASEAN and IMP-EAGA. and DMT-GT activities share the same purpose. Since the partcipating countries in these sub-regional programmes are members of ASEAN there may exist overlapping country participation and geographical coverage in the sub regional programmes. Many ASEAN programmes, especially those in infrastructure, human and the environment, could be implemented with greater focus and at a more rapid pace when carried out in the smaller area and context of the sub-regions. Enhancing coordination among the GMS, BIMP-EAGA and IMT-GT sub-regional programmes with ASEAN will help bridge the gap between project-driven "bottom-up" and policy-driven "top- down approaches to economic integration and promote closer linkages between the sub- regional programmes and ASEAN. It will also be necessary to examine how to more closely coordinate the three sub-regional programmes in terms of sub-regional analyses and assessments, and programme and project planning.
