Orlen refinery in Ukraine?

According to Rzeczpospolita, PKN Orlen made an offer to construct a $5 billion refinery in Ukraine in cooperation with Azeri firm Socar during the recent visit of PM Donald Tusk to Kiev.

This news was confirmed by Orlen's deputy president, Cezary Filipowicz, but he was careful to add that no official documents had been received from the Ukrainian side.
