BCIM Economic Corridor is an important project to be promoted by Bangladesh，China，India and Myanmar. BCIM Economic Corridor will not only have great influence on the opening up and economic cooperation of the four countries but also on the economic development of the region and Asia as a whole. For the time being，BCIM Economic Corridor is unfolding in a positive manner. In order to promote and implement this project，it is imperative to lay great emphasis on security issues. The security situation in the BCIM region is complicated and denies short-term solutions. From a long-term perspective，the four countries are supposed to be attentive to security issues and find conducive solutions so as to ensure a secure environment for the unfolding of BCIM Economic Corridor. In the meanwhile，despite the fact that the overall security situation fail to change for the better，cooperation projects are to be implemented in places that enjoy favorable circumstances while resolving security issues during economic development. Only by such means can the BCIM Economic Corridor yield fruits early and benefit the people rapidly.
