Once there is harmonization of ASEAN standards and professional certifications, it will open up greater opportunities for skill upgrading in all areas of human resources, leading to improvements in work quality in the various ASEAN professional and craft categories. It will make sense to harness the ASEAN diversity in human resources by systematically facilitating free flow of ASEAN workers and talents to where they are needed the most. In the process, this can unleash the full potential of the 600 million ASEAN citizens and develop ASEAN into the formidable economic region that it ought to be.
