Because of its geopolitical location these borders are very porous and, as a consequence, are highly difficult to monitor and control, making it vulnerable spots for illegal activities such as arms smuggling. This paper aims to examine the challenges faced by Indonesia and Malaysia in dealing with the main security border issues. The paper then concludes that Malaysia has become the main route for small arms illicit trafficking from other Southeast Asian countries to Indonesia＇s conflict areas. Indonesia and Malaysia face an enormous challenge, particularly in view of the recent happenings in conflict zones and the increasingly need to secure their common borders.展开更多
