HG: Your Excellency, thank you so much for joining CNBC. I want to kick off this conversation by talking about what we're seeing in the oil markets. A lot of people here at Davos say that OPEC is pretty much irrelevant. Would you say that that's the case?

SM: No, I disagree. I think OPEC still plays a key role, and what we are seeing in the market is definitely an oversupply, but it's not-, I mean, all of the signs say it's going to get better, and I can give you some figures, but what's important in the slow cycle of oil prices, the reforms that happened in the Arab world and especially in the Gulf states, and that's what we need to continue doing. So we are-, I'm happy, actually, that this is happening and we are doing something about it. We all know that the current prices are not sustainable, and I think if I ever see both the producers and the consumers agreeing on something related to the price, all of them, they will tell you today those are low prices, which means that they are not sustainable. The market will balance itself, ultimately, and the timing is not going to be way far from either-, there are two camps, there are optimistic people and there are pessimistic, and I am with the first camp, and I think this is a year of correction. The first half of the year is definitely not going to be easy, but on balance I don't see this year as hugely different than the year 2015 pricewise, therefore we are going to see correction in my view in the second half, because I cannot see from where additional oil is going to come from, except from Iran, and their announcement, and that is not going to offset the growth in demand, so I am optimistic.
