Extracts from a New York Times article by William J. Broad published in print on 18 May 2014
When Russia seized Crimea in March, it acquired not just the Crimean landmass but also a maritime zone more than three times its size with the rights to underwater resources potentially worth trillions of dollars.
Russia portrayed the takeover as reclamation of its rightful territory, drawing no attention to the oil and gas rush that had recently been heating up in the Black Sea. But the move also extended Russia’s maritime boundaries, quietly giving Russia dominion over vast oil and gas reserves while dealing a crippling blow to Ukraine’s hopes for energy independence.
