As reported by Censor.NET citing Ukrinform, this was announced by Ukraine' Prime Minister Volodymyr Hroisman at a briefing after Ukrainian forum on energy efficiency.
"I need to stress this again that in the expert sector, there is this understanding that signing of the contract at $450 was disadvantageous for Ukraine - this is a fact. How to treat it, depends on each individual. My position is that it was very negative. I believe this is betrayal of national interests, unfortunately," Hroisman said.
According to him, tens of billions of dollars paid by Ukraine to Russia is a problem Ukraine will long be dealing with.
This fact, the PM stressed, means that then-Prime Minister Tymoshenko did not put the state as her top priority.
Earlier, the contract for gas supplies for Ukraine in 2009-2019 was signed on Jan. 19 by heads of Ukraine's Naftohaz and Russia's Gazprom upon an agreement between Tymoshenko and Putin.
