He assured Putin that Greece will take all necessary steps for the completion of these negotiations.

Regarding the Burgas-Alexandroupolis oil pipeline, the Greek prime minister stressed the need to update a study for the project and the two leaders expressed conviction that work on the pipeline will proceed according to existing schedules.
