The influential Saudi and Russia-led oil producers' alliance is preventively prepared to wait months for guidance from "real numbers" before adjusting policies amid price volatility in the crude market, the Saudi energy minister said Sunday. "Yes, we may be delayed with a decision on what to do, but I would not forfeit the precautionary approach, even if it goes beyond a month or two, or three or four months, or five months," Prince Abdulaziz bin Salman told CNBC's Dan Murphy on the sidelines of the MENA Climate Week in Riyadh.
