When the rules of international law, practices and conventions are all studied, it becomes evident that there exist certain rules of international legislation which enable the countries not bordering the high seas to reach the open seas. However, differences in practice arise due to geographical conditions, balance of power and economic development. In order for the countries concerned to reach the open seas and benefit in transit from the territory of the neighboring countries located by the high seas for trade and transportation, it is essential that the two countries should have good relations and that the country bordering the high seas should have good-intention. Because in Eurasian Geography, almost none of the countries in Central Asia and Caucasus do not border the open seas, they are in need of other countries for trade and transport. In this study, the focus is on this issue.
