In trade facilitation, BIMP-EAGA has pioneered in phasing the implementation of relevant ASEAN programmes like ASEAN Single Window(ASW). The BIMP-EAGA Customs, Immigration, Quarantine and Security(CIOS) Task Force was established in 2006 and has mapped gaps and needed reforms in existing CIOS rules, regulations and procedures against international standards and is coming up with a Memorandum of Understanding on CIOS Harmonisation to help achieve a streamlined and simplified CIOS processes as well as CIOS agenda consonant with international and regional standards and best practices. However, implementation of CIOs reforms and trade facilitation programmes so far are often challenged by varying levels of compliance with international conventions and best practices both within d between the member countries and are mainly built on practical and short-gestating measures that are aligned with national programmes and priorities.
