Poland agrees to expand purchases of US liquefied natural gas by one third, Presidents Donald Trump and Andrzej Duda announced Wednesday at the White House. Trump said: “Over the past years, Poland has contracted with American firms for a total of about $25 billion to purchase more than 6 billion cubic meters of US liquefied gas. Today our countries have signed another contract for the supply of an additional 2 billion cubic meters worth about $8 billion.” Poland plans to stop importing gas from Russia after 2022.
