Russian Energy Minister Alexander Novak said on Monday that the gas talks between Ukraine, Russia and the European Union will continue at the end of November, just a month before the current deal expires.

Novak made the comments on Russian Rossiya-24 TV after another round of talks ended in Brussels, Reuters said.

The current gas transit agreement between Moscow and Kyiv expires after December 31. The bulk of Russian gas sent to Europe flows via Ukraine.

There are a number of obstacles to a new deal, such as a political row between Kyiv and Moscow, the war in eastern Ukraine, and litigation between Russian gas supplier Gazprom and Ukraine energy company Naftogaz.
