Experts say U.S. companies are unlikely to import Russian diesel while a fuel tanker sits idle off the U.S. East Coast, despite President Donald Trump's temporary lifting of sanctions on fuel exports from Moscow. Banks will likely be reluctant to finance American deals to purchase Russian diesel, experts say, noting that there are legal questions as to whether the president's refusal is enough to allow imports, Reuters reported. There are also operational challenges as importers will have to blend Russian diesel to meet US heating oil specifications. US lawmakers from both parties opposed Trump's temporary repeal of part of the law that imposed sanctions on Moscow over the conflict in Ukraine.
