The Southeast Asian nation's overall score in the index was largely unchanged at 1.738. The country remained in the GPI's second-highest category.
The index groups countries into five tiers: very high, high, medium, low and very low levels of peace, along with a separate category for countries not included in the report.
With this score, Viet Nam is also in the top four most peaceful countries in Southeast Asia, ranking behind Singapore (1.435), Malaysia (1.513) and Timor-Leste (1.681).
Produced by the Institute for Economics and Peace since 2007, the annual GPI report ranks 163 independent countries and territories according to their level of peacefulness, covering 99.7 per cent of the world's population.
It measures the state of peace across three domains: societal safety and security, ongoing domestic and international conflict and the degree of militarisation./.
