After an unfavorable ruling of the arbitration court, Gazprom announced that it would not deliver gas to Ukraine in March. It is about contracts for gas supplies and transport signed with Naftogaz in 2009. Russian Gazprom has lost arbitrage on both contracts. On February 28, the Stockholm arbitration court ruled that Gazprom should pay Naftogaz $ 4,63 billion for the shortage of gas supplies under the existing transit agreement, which probably upset the Russian giant. Kiev has launched an early-warning system and announced that it could run out of gas. At the same time, it informed that Gazprom deliberately does not provide a level of supply guaranteeing the stability of the Ukrainian transmission system. The situation may be improved by supplies from the European Union, for example from Poland.
