One of the most important mutual balancing factors of bilateral and multiple relations is rights and liabilities in international relations. It is certain that if the parties approach the issue within the framework of their rights and liabilities in dispute matters, they will be closer to a solution. However, the ongoing disagreements that have lasted for many years, firstly about the Aegean Sea and now the Eastern Mediterranean, are due to the fact that a certain country and interest group do not accept this basic concept. In other words, problem is due to the fact that acts on the basis of unilateral interests, which is far from a fair sharing approach based on mutual rights and liabilities. In this regard, particularly in the Eastern Mediterranean, Turkey’s interest and strength of relationship with other riparian countries, in accordance with the necessary mutual maritime jurisdiction areas, is crucial to strengthen its position on the deal.
