A Russian-flagged tanker, the 'Anatoly Kolodkin', delivered approximately 700,000 barrels of Russian Urals crude oil to Cuba's Matanzas Bay in late March, circumventing the US blockade.

Russia is planning to send a second oil tanker to Cuba, following the recent arrival of the 'Anatoly Kolodkin' with 730,000 barrels of oil, marking the first such shipment in three months.

The Russian-flagged oil tanker Anatoly Kolodkin is currently traversing the North Atlantic en route to the Caribbean, where the United States maintains an oil embargo against Cuba.
