The COVID-19 outbreak has brought unprecedented challenges, which are expected to have significant impacts on the development of Vietnam's economy this year. Based on the current situation, we explore the potential impacts of the COVID-19 pandemic outbreak on the Vietnamese economy. This study is associated with a significant degree of uncertainty. In particular, during the COVID-19 pandemic, projections are re-checked and revised every week since the start of the pandemic outbreak. Moreover, the Vietnamese economy is highly dependent on other economies. As a result, the scenarios and projections related to the impacts on the Vietnamese economy are also correlated with the economic impacts of other countries following the COVID-19 outbreak. We hope this publication can help businesses prepare for, cope with, and weather this risky and volatile environment.
