Direct investment inflow from Thailand into Vietnam has recorded breakthrough growth this year, according to data from the Foreign Investment Agency (FIA).
In the first nine months of 2025, Thai investors registered 26 new projects in Vietnam, with total capital exceeding $928 million — a sevenfold increase compared to the same period last year.
Cumulatively, as of the end of September, Thailand had 775 valid investment projects in Vietnam, with total registered capital of over $14.96 billion, ranking eighth among countries and territories investing in Vietnam.
Thai investment spans a range of key sectors, including energy, retail, food processing, green materials, and logistics. In addition to large corporations, small and medium-sized enterprises from Thailand are also actively expanding operations in Vietnam.
Major Thai conglomerates such as SCG, Central Retail, and CP Group continue to strengthen their presence, increasingly focusing on renewable energy, green materials, and the circular economy—sectors that align with Vietnam’s sustainable development goals.
Thailand remains not only a major investment source but also Vietnam’s largest trading partner within ASEAN. Bilateral trade between the two countries reached $20.2 billion in 2024, up 6.6% year-on-year, with both sides targeting $25 billion by 2026.
