Vietnam's merger control regime is governed by its general law on competition, the Law on Competition (2018), which includes definitions of concentrations, basis for notification and dossier requirements, process of review and prohibited acts. Said law is supplemented by the Decree No. 35/2020/ND-CP which sets forth the substantive assessment guidelines of concentrations and the notification thresholds. The law prohibits concentrations that create or are likely to create significant restriction to competition in any market in Vietnam. The Vietnam Competition Authority (VCA), established on 1 April 2023, enforces Vietnam’s merger control law.
