“America is back” has served as President Joe Biden’s zippy tagline to the world, reassuring allies that the United States is re-adhering to its international commitments. This sentiment is needed nowhere else more than in Asia. As the geopolitical landscape shifts in the Indo-Pacific, renewed American engagement is crucial to securing influence and stability. The United States, in the face of a rising China, needs to strengthen its Asia ally framework, starting with Japan and South Korea (the Republic of Korea/ROK).
This is not an easy task. Conflict has long characterized Japan-ROK relations. As a consequence of three decades of brutal Japanese occupation, South Korea presently seeks to address wartime grievances, such as forced labor and sexual slavery. Japan has managed to deny and downplay any crimes committed, igniting many diplomatic disputes throughout the decades. Now, recent major trade and security disputes have caused the Japan-South Korea relationship to drastically deteriorate, creating an information-sharing vacuum on China and North Korea. Given this instability, tensions between allies jeopardizes U.S. influence and relationships in the region.
The United States needs to actively engage in repairing relations between our allies in order to secure and strengthen our influence in the Indo-Pacific. The US can achieve this by further increasing trilateral cooperation between the US, Japan, and South Korea. For example, the State Department, through summit diplomacy, can redirect focus on areas of joint cooperation and on uncertain state actors like China and North Korea.
The US-Japan-ROK trilateral relationship has proven effective in cooperating security issues regarding aggressive state actors. Despite ongoing tensions, Japan and South Korea have a strong track record with US security collaboration, with all three militaries holding “Defense Trilateral Talks” (DTT) since 2008. The DTT talks have allowed for strengthening the security environment in Korean airspaces. Furthermore, all three countries, in 2014, signed “the Trilateral Information Sharing Agreement,” which allowed increased security cooperation on North Korea. This agreement allowed for classified information exchange on missile defense, strengthening the Northeast Asia security environment.
The Biden Administration has already taken concrete steps to strengthen its Asia position, focusing on US-Asia alliances. Four years of Trump has destabilized US foreign policy commitments, losing the trust and confidence of longstanding allies, especially in Asia. For example, Japanese officials were highly insulted by their exclusion in US-DPRK summit talks in 2018. US-South Korea relations were negatively affected by Trump’s repeated accusations on South Korea free-riding on the shared defense budget. President Biden has sought to repair this damage by showcasing the importance of Japan and South Korea. In fact, former Prime Minister Suga Yoshihide and President Moon Jae-in were the first foreign leaders to visit the White House since the start of the COVID-19 pandemic. These high-level meetings have displayed a shared commitment to combating China in economic and military spaces. The administration needs to continue engaging Japanese and South Korean diplomats to work on security and economic frameworks to combat China’s growing rise.
Reignited focus on the US-Japan-ROK trilateral relationship through summits and framework agreements will be noted as a major step towards alleviating tensions between the two countries, and will be a building block in strengthening the U.S. ally architecture in East Asia. Overall, it is imperative that the United States engage Japan and the ROK to refocus on regional cooperation. Critics argue that the United States has no place in repairing Japan-ROK relations, as these historical issues are deeply embedded in Japanese/ROK domestic politics. However, the United States does not need to solve or even speak to grievances but utilize an option in its diplomatic arsenal that has worked in the past, which will lead to stronger, more robust alliances in the Indo-Pacific.
