On 2 May 2026 Takaichi arrived in Hanoi, met Le Minh Hung, signed six agreements, met President-To Lam and addressed Vietnam National University. She departed for Australia on 3 May.
Agreements and Economic Indicators
The six accords cover infrastructure, climate action, agriculture, technology, digitalisation and space. Japanese investment fell 75 % YoY to US$233 million in Q1 2026, while pledged 2025 investment rose 19.4 % to US$3.08 billion. Bilateral trade grew 12.3 % YoY to US$13.7 billion. Under the US$10 billion Power Asia Initiative, Japan will help supply crude oil to Vietnam’s Nghi Son Refinery.
Official Statements & Policy Directions
Takaichi said economic security is now a bilateral priority and urged joint strengthening of regional petroleum-product supply chains. Hung affirmed Vietnam’s support for the Free and Open Indo-Pacific vision, called for peaceful resolution of South China Sea disputes, and welcomed cooperation on critical-mineral coordination.
Criticism and Business-Environment Concerns
Japanese officials flagged a sharp investment slowdown, citing delayed payments and limited access to large infrastructure projects. Japan also withdrew from a Vietnamese nuclear-power project over a restrictive timetable, underscoring regulatory friction.
Regional Implications
Cooperation on critical minerals and the Power Asia Initiative aims to cut dependence on Chinese supplies and boost energy security. Joint work on AI, semiconductors and space strengthens technology capacity, while a commitment to a rules-based South China Sea supports Indo-Pacific stability.
Conflicting Data & Gaps
Sources show a 75 % drop in Q1 2026 Japanese investment yet a 19.4 % rise in pledged 2025 investment, leaving the outlook unclear; implementation timelines for the six agreements and projected critical-mineral trade volumes remain undisclosed.
