Russia is unlikely to take part in the meeting of the Organization of the Petroleum Exporting Countries, or OPEC, set for May 28, the Interfax news agency reported Thursday, citing the country's First Deputy Prime Minister Igor Sechin.
"Only OPEC members will participate, so the chance a Russian delegation will go is very slim," Sechin said.
Russia, the biggest producer of crude oil outside OPEC, has attended some of the group's meetings in the past in a move to help support prices.
But despite assurances to OPEC members last year that Russia would cut production in order to help curb global supply, the country's oil output rose in the first months of this year.
