The 1936 Montreux Straits Convention replaced the contract on the straits made in Lausanne in 1923. The Montreux Convention uses the term “Turkish Straits” for the Dardanelles, Marmara Sea and Istanbul Strait and makes legal arrangements for maritime transportation between the Aegean Sea and the Black Sea. The Montreux Convention regulates the transition regime in detail by distinguishing between merchant ships and warships and warships, between states with a coast to the Black Sea and non-states, between time of war and situations of peace and war.
A special treaty regulating passage through the Turkish Straits Montreux Convention Regarding the Regime of the Straits because it contains provisions under the existing conditions in favor of Turkey, although Turkey has the right to choose to terminate it.
Unlike the Straits, the concept of “canal” is used in international law to refer to the man-made waterway that connects two sea areas. Since the canals are formed as a result of the excavation of the land country (land) of the state, the state’s authority over the canal is full. However, since the construction of the Istanbul Canal project is planned not to completely eliminate the passage through the Turkish Straits, but only bypassing the Bosphorus part, the rules stipulated by the Montreux Convention will continue to be applied. As a matter of fact, before or after reaching the Istanbul Canal, it will be necessary to enter the Turkish Straits and pass from there. It should also be reminded that the Montreux Convention limits not only the passage through the straits, but also the stay in the Black Sea for the states that do not have a coast to the Black Sea, in terms of time and tonnage. These restrictions will continue to exist in the passage made using the Turkish Straits and Istanbul Canal.
As a result, Istanbul Canal project will not prejudice the Montreux Convention, that states bordering the Black Sea, Montreux foreseen by the regime in the current circumstances and in favor of Turkey and Turkey meticulously and as long as they continue to transparency practices will apply this agreement may be specified.
