Energy security was a main topic as the prime ministers of Bulgaria and Turkey met in the Turkish capital Ankara.
Boyko Borisov and Recep Tayyip Erdogan signed around 20 agreements, including cultural exchanges, the setting up of a ferry route between their two counties and cooperation over natural disasters — particularly flooding.
They also agreed to connect the two countries domestic gas networks.
A pipeline running around 80 kilometres could then be used to transfer natural gas coming originally from Azerbaijan, via Turkey, to Bulgaria.
It is known that the Bulgarian government is keen to reduce its energy dependence on Russia but officially this pipeline connection would be used only in case of emergencies.
