MOSCOW--Russian gas monopoly OAO Gazprom (GAZP.RS) said Wednesday it will increase the annual gas capacity of the Blue Stream pipeline to 19 billion cubic meters from 16 billion cubic meters and deliver a record volume of gas to Turkey this year.

Russia will this year deliver 30 billion cubic meters of gas to Turkey through the pipeline that runs through the Black Sea, up from 26.6 billion of cubic meters a year before, the company said in a statement.

Gazprom's Chief Executive Alexei Miller and Turkish energy minister Taner Yildiz agreed that the pipeline will soon be loaded with Russian gas "to the maximum."

Mr. Miller said Turkey was Russia's "most dynamically developing market from the point of view of deliveries."

Russia is at loggerheads with Ukraine and the relationship between the two countries has been marred by conflict over gas infrastructure, transit, prices and payments.

With the Nord Stream pipeline through the Baltic Sea to Germany and Blue Stream to the South, Russia has cut the volumes of gas it transports via Ukraine by more than a quarter over the past six years. But Russia still delivered half of its natural gas to Europe through Ukraine in 2013.

Amid the crisis in Ukraine, Europe has begun to look elsewhere for gas supplies and Gazprom has started exploring new export opportunities.
