Though the country escaped the worst effects of the pandemic, its businesses and consumers affected by Covid-19 needed great support, but it would be difficult since Vietnam’s public debt-to-GDP ratio was 65 percent.
The fiscal deficit would increase to 5.2 percent of GDP in 2020 before falling to 4.6 percent in 2021, resulting in public debt falling below 60 percent.
