The amount of gas delivered through Ukraine has been consistent so far this week, the spokesman said. It's increased, however, from the 6.5 million cubic feet sent across Ukraine on June 18.
Gas shipments to Ukraine were halted June 16 when Gazprom said it needed to be paid in advance by its Ukrainian counterparts.
Gazprom meets about a quarter of the gas demands from Europe, though most of that runs through the Soviet-era transit network in Ukraine. Gazprom says it's owed billions of dollars in outstanding gas debt from Ukraine and similar rows in 2006 and 2009 resulted in gas shortages for Europe.
June meetings between Russian, Ukrainian and European authorities focused on settling the debt issue.
Gazprom says those negotiations are ongoing.
