KHARKIV, Oct 1 - President Petro Poroshenko is confident that all the funds won by Ukraine in courts against the Russian Federation will be returned to the Ukrainian state.

"We reached the Stockholm court and won $4.6 billion, which, due to this contract, were overpaid to the Russian Federation, the aggressor country. And today let them not flatter themselves - this sum will be fully paid to Ukraine. No, sorry, even more will be returned, because every day when Russia does not pay, the amount of payment is growing by half a million dollars... And I have no doubt that the amount will be received in the near future," he said at the opening of the tenth international economic forum "Innovations. Investments. Kharkiv Initiatives!"
