ABU DHABI- Russia's Gazprom Neft , the oil arm of Russia's gas giant Gazprom, said on Tuesday the OPEC, non-OPEC deal for cooperation in oil markets should become a constant mechanism.

"We need to consider the deal as a constant mechanism in place, that this becomes sort of part of the rules of the game," first deputy CEO Vadim Yakovlev said at an energy conference in the UAE capital Abu Dhabi.
