MOSCOW/LONDON, Nov 23 (Reuters) - Three major Greek shipping firms have stopped transporting Russian oil in recent weeks in order to avoid U.S. sanctions now being imposed on some shipping firms carrying Russian oil, four traders told Reuters and shipping data showed.
The development is a blow to Russia as it narrows the number of shipping firms that are ready to transport Russian oil to consumers in Asia, Turkey, the Middle East, Africa and South America - although traders said Moscow still had enough shipping firms for now.
