Meanwhile, Russian President Vladimir Putin has warned that Europe faces "major transit risks" to natural gas supplies from Russia this winter.
Putin told reporters in Belgrade on October 16 that if Ukraine siphons off natural gas without permission from transit pipelines to the European Union, Russia “will consecutively reduce the stolen volume at the cost of supplies."
Putin made the remarks ahead of talks in Milan on October 16 and 17 with EU leaders and Ukrainian President Petro Poroshenko.
Russia raised the price it charges Kyiv for natural gas after Ukraine's pro-Russia Preident Viktor Yanukovych was ousted in February, then halted gas supplies to Ukraine in June when Kyiv failed to pay the higher price.
The price standoff is the third between Moscow and Kyiv since 2006.
Russia is the EU's biggest gas supplier, providing about a third of the gas consumed there.

Meanwhile, in Crimea:
Crimea's Moscow-backed leader, Sergei Aksyonov, has acknowledged that four members of the Muslim Tatar minority on the annexed peninsula are missing but asserts they were not abducted.
Speaking on October 16, Aksyonov criticized missing Crimean Tatars by saying some of them had fought in Syria, implying they were Islamic militants.
At least three Crimean Tatar men have been found dead since Russia annexed the Black Sea region from Ukraine in March.
Human Rights Watch said earlier this month that three Crimean Tatars remained missing after "hostile encounters" and that some of those found dead had apparently been tortured.
Pressure on Crimean Tatars, a Turkic-speaking group that largely opposed the annexation, has increased in recent weeks.
Last month, Russian authorities seized the Crimean Tatar assembly, the Mejlis, and searched homes of leading members of the Tatar community.
