Japanese Prime Minister Sanae Takaichi began a three-day visit to Vietnam on May 1, 2026, meeting with top Vietnamese leaders. During the visit, Takaichi reaffirmed the Japan-Vietnam Comprehensive Strategic Partnership and discussed new areas of cooperation, including rare earths and security assistance.

Takaichi's engagements included meetings with To Lam, General Secretary of the Communist Party of Vietnam and President; Le Minh Hung, Prime Minister of Vietnam; and Tran Thanh Man, National Assembly Chairman of Vietnam. In her meeting with Lam, Takaichi indicated that the Japanese government would promote Official Security Assistance.

Takaichi and Lam agreed to advance cooperation on rare earths for economic security. Lam identified six areas for enhanced strategic cooperation, including strengthening political trust, deepening defense and security cooperation, and advancing economic collaboration while addressing security concerns. He also called for expanding cooperation into digitalization, energy transition, and artificial intelligence.

Lam stressed scientific and technological collaboration through human resource development and joint research, and encouraged broader people-to-people exchanges across labor, education, culture, and tourism. Takaichi extended a formal invitation for Lam to visit Japan, and they agreed to target a visit within 2026.

Takaichi delivered a foreign policy speech at Vietnam National University in Hanoi, outlining an updated Free and Open Indo-Pacific vision. Focus areas of this vision included building economic infrastructure for the age of AI and data, co-creating economic growth opportunities through public-private collaboration and rule-sharing, and deepening security cooperation to ensure regional peace and stability.

Why It Matters

The visit continues a pattern of Japanese prime ministers visiting Vietnam early in their tenure, a trend observed since 2012. Japan has served as Vietnam's largest Official Development Assistance provider for 20 years. The expansion of the Comprehensive Strategic Partnership reflects a broader diplomatic strategy; five years prior to 2026, Vietnam had such partnerships with three countries, a number that has grown to 15 by 2026. This includes the China-Vietnam Comprehensive Strategic Partnership, which incorporates the formulation 'Building a China-Vietnam community with a shared future that carries strategic significance.'

Vietnam's defense policy is anchored in the 'Four No's': no military alliances, no foreign military bases, no siding with one country against another, and no use of force in international relations. The expressed desire for cooperation in rare earths and security assistance indicates potential shifts or expansions within these established diplomatic and defense frameworks.
