Polands second-biggest refiner Lotos is eying for sealing a long-term oil supply deal with Iran.

Lotos Chief Executive Officer Marcin Jastrzebski stated that the deal could be signed with Iran after his company completed a new coking unit at its Gdansk refinery next year.

This could be part of the companys plans to diversify its imports of oil and gas away from Russia, its largest supplier, Reuters wrote in a report on Jastrzebskis announcement.

Lotos CEO acknowledged this, but emphasized that the plan was meant to improve the financial performance of his company, as well.

"The primary goal of the diversification is to improve (financial) results not just to change suppliers," he said.

Last year, the Polish company signed an oil purchase agreement with National Iranian Oil Company (NIOC) and the first tankers carrying 2 million barrels of Iranian oil arrived in Poland in mid-August. It is now in talks to receive another 2 million barrels.

Irans shipment of oil for Lotos was the countrys first sent to Poland after the removal of sanctions against the Islamic Republic in early 2016.

There were other indications that Poland was increasing its imports of oil from Saudi Arabia, as well. This was also seen as part of Warsaws policy to reduce its dependence on Russian oil.
