After failing to reduce their reliance on Moscow for energy, Hungary and Slovakia now want help from Brussels.

You reap what you sow.

Privately, that’s the exasperated sentiment among EU diplomats as Hungary joins with Slovakia to try and leverage EU rules to preserve access to a discounted product nearly everyone else has had to shun: Russian oil.

Their maneuvering comes in the wake of Ukrainian sanctions blocking the transit of pipeline crude sold by Russia’s largest private oil firm, Lukoil, which could strip the two countries of a third of their oil imports.

Hungary and Slovakia have gone to the rule book, arguing the penalties violate a 2014 trade deal between Kyiv and the EU and asking the European Commission, the EU’s executive, to intervene.
