Vietnam‑Japan Trade Hits $52 bn in 2025, Japan Leads Investment and Vaccine Aid

Context Prime Minister Takaichi Sanae’s first visit to Vietnam underscores a deepening comprehensive strategic partnership that began in 1973. The two nations have moved from a stable partnership in 2002 to a comprehensive strategic partnership in 2023, covering trade, investment, education and emerging technologies.

Key Facts - Bilateral trade reached about $52 billion in 2025, exactly twice the 2014 level. - As of 31 January 2026, Japan operated 5,722 investment projects in Vietnam, with a total registered capital of $78.9 billion, ranking third among all foreign investors. - Japan was the first country to supply COVID‑19 vaccines to Vietnam, a move that cemented health‑sector cooperation during the pandemic. - The two governments have agreed on 15 green‑energy projects worth roughly $20 billion, including power plants and a biomass facility.

What It Means The trade figure signals that Vietnam has become a more significant market for Japanese goods and services, reflecting complementary supply chains and consumer demand. Japan’s investment footprint, now approaching $79 billion, shows confidence in Vietnam’s manufacturing base and its role in regional value chains. Early vaccine delivery boosted public goodwill and set a precedent for rapid health collaboration, which may translate into joint research on biotech and pandemic preparedness.

Looking ahead, the success of green‑energy projects and cooperation in AI, semiconductors and digital transformation will test the partnership’s ability to move beyond traditional sectors. Monitoring the rollout of the agreed $20 billion green portfolio will indicate how quickly the two economies can align on climate goals and secure new growth avenues.
