The export of crude oil to the EU countries from Russian ports in the Black Sea in January 2023 showed an increase compared to the previous month by 25% – up to 1.27 million tons, despite the oil embargo that came into force on December 5, according to a study by the Institute of Black Sea Strategic Studies and BlackSeaNews. Russian oil was transported to four EU countries: Greece imported 961,100 tons (75% of the total volume), Spain imported 159,100 tons, the Netherlands 103,600 tons, and Slovenia 50,300 tons . To Slovenia, the Netherlands, and Spain, tankers with Russian crude oil arrived directly at the ports, to Greece – at anchorages in the territorial sea.
