An analysis by OBA Mie, a professor at Kanagawa University specializing in Indo-Pacific regional studies, proposes that Japan has an opportunity to serve as a “third option” for the Association of Southeast Asian Nations (ASEAN). The perspective was detailed in a published commentary addressing ASEAN’s strategic position relative to the ongoing competition between the United States and China.
According to Oba’s analysis, ASEAN member states are navigating complex diplomatic and economic pressures from both Washington and Beijing. The analysis frames the geopolitical environment as one where nations in the region seek to maintain autonomy and avoid exclusive alignment with either major power. In this context, the commentary posits that Japan could offer an alternative partnership.
Oba identifies several factors that position Japan as a potential partner for ASEAN. The analysis points to Japan’s long-standing economic engagement in the region, including significant investment in infrastructure, technology, and development aid. It also references Japan’s promotion of a “Free and Open Indo-Pacific” (FOIP) vision, which emphasizes rule-of-law, freedom of navigation, and connectivity. This approach, Oba writes, aligns with the principles of the ASEAN Outlook on the Indo-Pacific (AOIP).
The commentary suggests that for Japan to fulfill this role, it must continue to respect “ASEAN Centrality,” a guiding principle that places the 10-member bloc at the center of the regional architecture. Oba’s analysis argues that Japan’s potential success depends on its ability to offer partnerships without demanding the stringent security commitments sometimes associated with the U.S. or the debt concerns linked to some of China’s initiatives.
The broader context for this analysis is the strategic competition between the U.S. and China. The United States has sought to strengthen alliances and partnerships in the region to counter China’s influence. Concurrently, China has expanded its economic and military presence through initiatives such as the Belt and Road Initiative and its activities in the South China Sea.
Oba’s article concludes that Japan’s approach, which has historically focused on economic and diplomatic cooperation, could present a viable model for engagement that allows ASEAN nations to balance their relationships and pursue their own national interests without being forced to choose between the two global powers. The effectiveness of this strategy, the analysis notes, will depend on Japan’s consistent and tangible commitments to the region.
