Political will. The political will to approach a dispute over the delimitation of maritime borders judiciously is essential. In the past, this critical factor has probably been compromised due to fisheries disputes, one of the fundamental practical issues of shipping and a source of persistent tensions between the two states. This problem was resolved by the 2001 Korea-China fisheries agreement, which would be the main source of daily conflicts between the parties in the area of overlapping maritime requirements and which should reduce the political impetus for the delimitation of a maritime border between China and the yellow coast. However, over time, it became apparent that this joint fisheries agreement did not allow for rational management of the fishery and a reduction in the number of fishing incidents between the parties. Despite significant challenges, the Coastal States of the East China Sea have taken a series of positive steps to manage their overlapping claims to the seenotiver jurisdiction. three joint fisheries agreements that were concluded following the ratification of the UN Convention on the Law of the Sea (CNULOS); the EEZ declaration by China, Japan and the ICC; and the overlapping maritime claims that flow from it – can be considered together. The fisheries agreements concerned are: the agreement between China and Japan of 11 November 1997 on part of the East China Sea; the agreement between Japan and South Korea in January 2000 for parts of the East China Sea and the Sea of Japan (known as the Baltic Sea in South Korea); and the agreement between China and South Korea on 30 June 2001 on parts of the Yellow Sea.  These historical and geopolitical remnants often hinder economic and social interactions between China and South Korea.
For example, the possible use by the United States of the High Altitude Area Defence Systems Terminal on South Korean soil has disrupted the imminent ratification of the China-South Korea free trade agreement. There is therefore an urgent need to reach an agreement on maritime cooperation. This should preferably encompass all of East Asia, rather than just China and South Korea. China has many maritime disputes in the East and South China Sea, but its only successful agreement on the maritime border is with Vietnam. China is also blocking agreement on a binding “code of conduct” for maritime cooperation between China and ASEAN. Both ASEAN and Japan have interpreted China`s claims in the East China Sea and South China Sea territories as a manifestation of the intention to restore regional order during the Central Empire era. Current discussions should focus not only on the long-term preservation of peace and order, but also on the concerns of China`s neighbours.
