U.S. President Joe Biden announced a ban on Russian oil and other energy imports on Tuesday over Moscow's invasion of Ukraine. Britain said it would phase out the import of Russian oil and oil products by the end of 2022.

European imports of diesel and gasoil from Russia and Baltic loading points are estimated at 662,000 tonnes this week, 22% lower than the previous week, according to Refinitiv data.

Russia's exports diesel from the Baltic Sea port of Primorsk are set to fall by 15.5% month-on-month on a daily basis in March to 1.478 million tonnes from 1.58 million tonnes scheduled for February, according to the preliminary loading schedule.
