The cargo of LNG was delivered to the Polish Baltic port of Świnoujście at the end of last week as part of a long-term deal Poland signed late last year with US company Cheniere Energy.
Poland’s Prime Minister Mateusz Morawiecki has said the deal is yet another stage of building Poland's energy sovereignty.
He added that achieving a strong position in terms of energy was one of the goals of his conservative government.
