KYIV, May 30 – President Petro Poroshenko has ordered that top managers of national joint-stock company Naftogaz Ukrainy do their best to ensure the recovery of $2.6 billion debt of Russia's Gazprom and the arrival of the money to Ukraine awarded by the Arbitration Institute of the Stockholm Chamber of Commerce.

"The process of the enforcement of recovery of $2.6 billion from Gazprom has been moved to practice. Today, the encumbrance of shares and other assets of Gazprom in European countries, in particular, Switzerland, the U.K. and the Netherlands was started. My clear order is that we must not stop on these three countries and do our best to ensure the arrival of awarded funds to Ukraine. We discussed this at a meeting with Naftogaz Ukrainy CEO Andriy Kobolev," Poroshenko wrote on his Facebook page on Wednesday.
