Revisions
The findings indicate that United States–Japan relations during the period 2021–2025 continue to constitute one of the most important strategic alliances in modern international relations, playing a prominent role in shaping the security architecture of the Indo-Pacific region. In response to intensifying great power competition, the rise of China, and emerging non-traditional security challenges, the two countries have expanded their cooperation beyond security to include economics, technology, energy, and supply chain resilience. However, the alliance continues to face challenges related to burden-sharing, strategic autonomy, and shifts in policy priorities. For Vietnam, the development of United States–Japan relations creates both opportunities for cooperation and the need to maintain an independent, autonomous, and strategically balanced foreign policy in order to preserve national interests amid intensification international competition.
