Beyond the South China Sea: 4 Other Maritime Flashpoints in East Asia

The disputes in the South China Sea, involving China, the Philippines, Vietnam, and others, are widely recognized as a major flashpoint in East Asia. However, there are four other maritime disputes in East Asia that, while less publicized, hold significant geopolitical influence. These disputes have the potential to reshape the geopolitical order in East Asia and, in the worst-case scenario, carry the risk of escalating into military conflict. This article analyzes these disputes in order, from least likely to most likely to spark military conflict, explaining their background and current status. Specifically, these include the Sino-Japanese confrontation over the Senkaku/Diaoyu Islands, the sovereignty issues around Jeju Island, and the waters around Dokdo/Takeshima, which are disputed between South Korea and Japan. These disputes are complexly intertwined with territorial claims, resource development, and security concerns of the involved nations, making them factors that cannot be ignored for the stability of the entire region. The dynamics of these maritime disputes not only directly impact the balance of power in East Asia but also have the potential to affect regional economic activities and international supply chains. Therefore, it is imperative for not only the respective governments but also the international community as a whole to closely monitor their developments.
