In 2004, Vietnam introduced its merger regulation with the first version of the Competition
Law, whose outcomes were criticized for their inefficiency. The current alternative law also leads
to making changes in this insufficient merger control. Several studies have presented a more
enforceable approach in this replaced version. However, there exists a rare identification of its
remaining shortcomings. Basing on the comparative aspect between the old and new versions of
merger regulation in Vietnam, this study traces the insight of movement from the static approach
to the integrated approach in the world of merger law. Not only does this article position the merits
supplied by the merger control in the 2018 law, but it also uncovers several newly emerging issues
related to the merger review and then application of merger remedies that would undermine the
effective regulation on mergers. The findings mainly focus on the shortage of economic
perspectives consumed in the legal designation. Notably, it offers some tentative reform proposals
to tame the shortage expression of merger remedy consumption. This will contribute implications
and recommendations for successfully implementing the more active merger review with approved
appropriate remedies in Vietnam in the future.
