Short answer. Vietnam received approximately USD 20.17 billion in FDI inflows in 2024, a 9.0% increase on the prior year, according to UNCTAD's World Investment Report data — a figure calculated on a different methodology from, and not directly comparable to, the MPI registered-FDI figures cited elsewhere in JMT's Insights series (registered commitments versus realised inflows are distinct measures, both legitimate but not interchangeable). Vietnam's inward FDI stock reached approximately USD 249.14 billion in 2024, representing roughly 15.1% of total Southeast Asian inward FDI stock — a meaningful share for an economy of Vietnam's size, and one that reflects a sustained multi-year trend rather than a single strong year. Indonesia, the region's largest economy by population and GDP, has consistently ranked among ASEAN's largest FDI recipients in absolute terms, reflecting its scale; Thailand's FDI profile in 2024 reflected a more moderate inflow picture in several sectors relative to its historical position as a regional manufacturing hub. The comparison that matters for an individual investor is rarely the aggregate ranking alone, but which market's regulatory environment, cost base, and sector-specific dynamics best fit the specific investment in question.
What the aggregate numbers show
According to UNCTAD's World Investment Report data, Vietnam received approximately USD 20.17 billion in FDI inflows in 2024, a 9.0% increase on 2023, with an inward FDI stock of approximately USD 249.14 billion — around 15.1% of total Southeast Asian inward FDI stock. This is a distinct measure from the MPI registered-FDI figures (USD 34.65 billion registered in H1 2026 alone) referenced elsewhere in JMT's Insights series; registered commitments and realised inflows are both legitimate, commonly cited figures, but they measure different things and should not be quoted interchangeably in an investment memo without noting which one is being used.
How Indonesia and Thailand compare
Indonesia, ASEAN's largest economy by both population and GDP, has consistently ranked among the region's largest FDI recipients in absolute terms — a reflection of sheer market scale as much as investment climate, and a genuinely different value proposition from Vietnam's: a much larger domestic consumer market, alongside a historically more complex regulatory and licensing environment for a first-time foreign entrant. Thailand, long established as a regional manufacturing and automotive hub, has seen a more moderate FDI inflow picture in recent data across several sectors relative to its historical positioning, reflecting both intensified regional competition for manufacturing investment and Thailand's own domestic political and policy environment over the period.
Why the ranking alone should not decide the question
Aggregate FDI comparisons are a useful starting orientation, but the investment decision that actually matters is rarely settled by which country ranks highest in a given year. Vietnam's specific advantages — a large, young, increasingly skilled workforce; the FTA network described in JMT's companion briefing on EVFTA, CPTPP, and RCEP; and a currently more permissive foreign-ownership environment for many sectors than some regional peers — are genuinely different considerations from Indonesia's domestic-market scale or Thailand's established manufacturing supply-chain depth. The right question for an individual investor is not "which country received the most FDI" but "which market's specific regulatory, cost, and sector dynamics fit this specific investment" — a question that requires a proper feasibility assessment, not a single comparative statistic.
Why does this article cite a different Vietnam FDI figure from other JMT Insights articles?
Because the figures measure different things: UNCTAD's USD 20.17 billion is a realised 2024 FDI inflow figure, while the USD 34.65 billion figure cited elsewhere is MPI's registered FDI commitment figure for H1 2026 — both legitimate, but not directly comparable without noting the methodology difference.
Is Indonesia a bigger FDI destination than Vietnam?
Indonesia has consistently ranked among ASEAN's largest FDI recipients in absolute terms, reflecting its much larger economy and population — this reflects market scale more than a direct like-for-like comparison of investment climate with Vietnam.
Is Vietnam still a strong destination relative to Thailand for manufacturing FDI?
Vietnam has shown sustained FDI inflow growth and a rising share of Southeast Asian inward FDI stock, while Thailand's manufacturing-sector FDI picture has been more moderate in recent data relative to its historical positioning — though sector-specific and company-specific factors matter more than the aggregate comparison alone.
Which data source should be used when citing Vietnam FDI figures to clients or partners?
Specify the source and methodology explicitly — UNCTAD's realised-inflow figures and MPI's registered-commitment figures serve different purposes and should not be presented interchangeably in the same document without that distinction.
Does a higher aggregate FDI ranking mean a country is automatically the better choice for a specific investment?
No — aggregate rankings are a useful orientation point but do not substitute for a sector-specific and investment-specific feasibility assessment of regulatory environment, cost base, and market fit.
How does JMT Private & Partners help investors compare Vietnam against regional alternatives?
JMT provides sourced, current market-entry and feasibility analysis comparing Vietnam against relevant regional alternatives for the investor's specific sector and investment scale, as part of its Pre-Investment Feasibility service line.
