PKN Orlen, Poland’s state-dominated oil company, is ratcheting up the pressure on the Lithuanian government to sell the Klajpedos Nafta oil terminal, which is the main supplier for its loss-making Mazeiku refinery.

PKN is so frustrated with Lithuania’s refusal to sell the terminal in the port of Klaipeda that it is not ruling out exiting its investment in the refinery, the largest industrial complex in the Baltic states.
