Polish oil firm PKN Orlen is in talks to buy Italian firm Eni’s stake in the Czech Republic’s sole refiner, the Czech industry minister said, a step that could lead to more investment and help secure its future. The sale of Eni’s 32.4% would give local PKN unit Unipetrol full ownership of Česká rafinérská after it also bought a 16% stake from Shell earlier this year for USD 27 million. “(Eni) is negotiating with PKN Orlen on the conditions for it to exit Česká rafinérská,” the minister told Reuters.
