East Asia is the biggest geopolitical challenge of the 21st century. With China’s rise
as superpower, strategic interests of the United States are concentrated in this region.
The United States shifted its policy to rebalance in the Asia-Pacific Region or Pivot to
Asia in order to constrain China’s rise and maintain its influence in the region. And the
ROK-US and the US-Japan alliances are the central axes of the US policy in this
region. However, Japan’s territorial disputes with neighboring countries, such as China,
Russia and Korea are creating new tensions in the region. In particular, the territorial
conflict over Dokdo between Korea and Japan has created a crack in the relationship
between Korea and Japan, the key allies of the United States in East Asia, which have
become a major obstacle to US policy.
This paper will examine the positions and policies of the alliances of US with respect to
Japan’s territorial disputes with neighboring countries in East Asia and examine their
meanings for the defense of Korea’s sovereignty over Dokdo.
In conclusion, the issues of Senkaku and Kuril Islands for the sovereignty for which
Japan is struggling with China and Russia and the Dokdo conflict between Korea and
Japan are completely different from the viewpoint of the US alliance. The former disputes
are conflicts between the a US’s key Ally and US’s potential competitors, the latter is
a conflict between Korea and Japan, key allies of the US in East Asia in response to
China’s rising. Therefore, the US’s policy goals for the Korea-Japan relationship are to
encourage these two allies to resolve the issue peacefully through negotiation, or at least
to keep the two from engaging in actions that could aggravate the dispute without
intervening arbitrarily, as traditionally. Anyway, the role of the United States in the
ROK-US alliance is the key in resolving the Dokdo issue. Therefore, it is necessary to
make Japan to recognize that the resolution of the Dokdo issue(recognition of Korea’s
sovereignty over Dokdo) is the starting point of a future-oriented relationship between
Korea and Japan for peace and prosperity in East Asia and give the United States a role
and responsibility to strive for the development of this relationship.
