Oil prices rose on Friday, hovering close to their highest levels in months, as major producers may wait until January before deciding whether to extend their output curbs beyond the first quarter.
Russia's energy minister said no decision was expected before January, although other ministers suggested such a decision could be taken before the end of this year.
"I believe that January is the earliest date when we can actually, credibly speak about the state of the market," Russian Energy Minister Alexander Novak said. Other ministers suggested a decision could come this year.
