Russian President Vladimir Putin had warned European leaders the region's energy security was at risk because of Ukraine's mounting natural gas debt. European consumers get about a quarter of their gas needs met by Russian energy company Gazprom, though most of that gas runs through the Soviet-era transit network in Ukraine.
"We have noted the positive tune of the European Commission about dialogue," the spokesman said.
Putin said he'd hold off on making any decisions based on Ukraine's gas debt for now. Gazprom in 2009 cut gas supplies briefly through Ukraine in response to a similar row.
Peskov said he didn't think the Kremlin's stance on Ukraine's gas sector was unreasonable.
Recently, European energy companies RWE and Eni said they'd take measures to ensure the Ukrainian energy sector is adequately supplied with natural gas.
