Hon Singh, yes, indeed, the policy of government and our approach is to diversify our sources so that we don't put all our eggs in one basket, so to speak. Of course, as we improve relations with source countries, that also guarantees us security of supply. We even have possibilities in South-South countries such as Venezuela. I know that our colleagues at PetroSA have also been looking in that direction to try and diversify our source as much as possible.
The rand-dollar exchange rate is a difficulty. It adds to the vicissitudes of the price and it creates difficulties for the economy as a whole. There is no doubt that once PetroSA begins to own blocks and begins to pump, we can fill up our reserve capacity with crude oil. This will also assist in regulating the price and protecting consumers from these vicissitudes.
