Ukraine’s national gas company Naftogaz is ready to settle its outstanding debts for Russian natural gas imports ifGazprom signs a deal guaranteeing winter supplies. Russia halted gas supplies to Ukraine in June over unpaid bills, saying state-owned Naftogaz owes it around $5 billion. It has said it won’t turn on the taps again without settlement of $3.1 billion of the debt this year and prepayment for deliveries of gas for November and December. Ukraine has said Moscow had set an unfairly high gas price to punish its pro-western government and has disputed the amount that Russian state-gas company Gazprom says it owes.
