Turkish authorities have decided to introduce more restrictions on the sailing of ships via the channels of Bosporus and Dardanelles. The introduced restrictions apply first of all to the transportation of oil and oil products. Explaining their actions by the ecologic security of the channels, Ankara, in fact, abuses its actual monopoly on the transit of cargos from Black Sea to the Mediterranean. However, the new navigation rules were dictated not only by the wish to get more money from the cargo transporters. The Turks, as usual, try to kill two birds with one stone: on the one hand – to get more money and on the other hand to secure the profitability of the Baku-Tbilisi-Jeyhan oil pipeline being constructed.
