Globalcompetitionreview – Under Vietnam’s Competition Law (VCL), economic concentration includes company mergers, consolidations and acquisitions, and the creation of joint venture. Since it was created in 2005, the Vietnam Competition Authority (VCA) has not officially rejected any proposals for economic concentration that have been notified. However, this does not necessarily mean that this aspect of competition law is overlooked in Vietnam. According to the VCA’s reports, since 2011, it has dealt with an average of three to four notifications per year. In addition, the VCA is closely monitoring merger and acquisition activities in the market by cooperating with the licensing authorities and administering the structural changes of enterprises to ensure that all economic concentration is properly controlled by the competition authority. Notably, on 22 December 2014, the prime minister issued Decision 2327/QD-TTg (Decision 2327), granting an exemption to a merger between the only two card networks, resulting in a monopoly in the relevant market. This is remarkable for being the first exemption granted by the prime minister after 10 year’s enforcement of the VCL.
