Bulgaria has reportedly cancelled a meeting with Russia where the two nations were due to discuss matters related to energy.

Reports claim the bilateral meeting was called off as a result of the EU’s decision to impose economic and visa sanctions on Russia for the annexation of Crimea.

The Bulgarian Ministry of Economy and Energy had reportedly planned to meet its Russian counterpart to discuss the price of Russian natural gas to Bulgaria and about plans to restart the Burgas-Alexandroupoli project.

It is a 174-mile oil pipeline project to transport Russian and Caspian oil from the Bulgarian Black Sea port of Burgas to the Greek Aagean port of Alexandroupoli.

Bulgaria had signed an agreement with Russia and Greece in 2007 to build the pipeline but backed out of the project last year.

The meeting is expected to be scheduled for June.
