FACTBOX: Russian oil and gas export interruptions

LONDON (Reuters) - Russia has cut oil and gas supplies to neighbors and indirectly to onward customers in recent years.

The following is a list of some supply interruptions and the reasons offered for them.

The Swedish Defence Research Agency, a government-linked body, said in a report in March 2006 that Russia had cut off exports on around 40 occasions.

Moscow denies that it uses energy as a political tool.

BELARUS

In a pricing dispute, Russia cut oil supplies to Belarus in January 2007 along the Druzhba, or Friendship, pipeline for three days, reducing exports to Germany and Poland.

Druzhba -- which passes through Ukraine and Belarus -- supplies Europe with around one tenth of its oil.

Russia's state controlled Gazprom has also threatened to cut off gas supplies to Belarus in price disputes. Around 20 percent of Russia's gas exports to Europe pass through Belarus.

LITHUANIA

In July 2006, Russia shut an oil pipeline to Lithuania's Mazeikiu refinery, saying it needed to be repaired to avoid a leak. The pipeline has not restarted.

Lithuania said the shutdown is a politically motivated action after the country sold its Mazeikiu refinery to Poland's PKN Orlen rather than to a Russian bidder.

Russian technical watchdog Rostekhnadzor said in September that pipeline company Transneft would need at least another 18 months for repairs, meaning the pipeline could not reopen before the end of 2009 at the earliest.

UKRAINE, JANUARY 2006

Ukraine has long haggled over how much it pays Russia for gas and the row came to world attention in January 2006, when it led Gazprom to halt supplies to Ukraine.

Onward supplies to Italy, France, Croatia, Poland, Hungary, Germany and Romania fell sharply but were restored within days.
