Vietnam, a one-party socialist republic, has undergone significant economic transformation since the lifting of U.S. sanctions in 1986. Transitioning from a closed, agrarian economy to a market-oriented system, the country has achieved notable progress, advancing from one of the poorest nations to a lower-middle-income status. Despite this progress, Vietnam faces several macroeconomic challenges including high inflation, a depreciating currency, and a growing trade deficit. The COVID-19 pandemic has exacerbated these issues, leading to disruptions in business activity, supply chains, and economic instability. Additionally, severe air pollution presents a pressing concern for public health and economic productivity. This paper examines Vietnam's current macroeconomic challenges, evaluates the impact of recent economic disruptions, and proposes policy recommendations to address these issues. Recommendations include increased health spending, structural reforms to enhance green growth, and monetary policies aimed at controlling inflation and encouraging investment. The analysis highlights the need for a balanced approach to sustain economic progress while addressing critical challenges.
