Ukrainian state energy company Naftogaz claims the Dutch assets of Russia's Gazprom have been seized in compliance with the decision of the Stockholm arbitration court.

In February, the Stockholm court demanded that the Russian company pay for a shortfall in the delivery of gas to Ukraine, awarding Naftogaz $2.6 billion in compensation. Gazprom said that the decision created an imbalance in favor of Kiev. The Russian firm appealed the verdict, and notified Naftogaz that it had launched a procedure for the termination of gas-delivery contracts.

Last week, the Ukrainian state energy company applied for the seizure of shares in Gazprom's subsidiaries. Kiev claims the Dutch court upheld the motion, but six out of the seven Gazprom subsidiaries "refused to cooperate with the legal executive."

"However, that has no impact on the seizure," the Ukrainian company added.

The headquarters of Gazprom International, which oversees the company's projects around the world, is located in Amsterdam. Gazprom Energy, another of the corporation's subsidiaries, is also based in the Netherlands.

"Naftogaz will use all legitimate measures and tools available to us to enforce the decision and fully recover the amount awarded from Gazprom," Naftogaz CEO Andrey Kobolyev said in a statement released on Tuesday.

Naftogaz has targeted Gazprom's other European assets. At the end of May, Swiss court officers made an inventory of properties attached to the office of the Gazprom-controlled Nord Stream AG project as part of the ruling by the Stockholm arbitration court. The Russian energy company confirmed the information, highlighting that it had not received any notice.

According to the Naftogaz statement, Swiss court bailiffs are currently seizing Gazprom's stakes in Nord Stream AG and Nord Stream 2 AG.
