由于伊朗战争导致航运中断，运费飙升至历史高点，美国官员周三表示，特朗普政府正考虑放宽对所谓“影子船队”船舶的制裁，这些船舶曾运输来自俄罗斯、伊朗、委内瑞拉等国的石油及石油产品，以帮助缓解油价。
With the Iran war having disrupted shipping and driven up freight costs to record highs, the Trump administration is considering easing sanctions on so-called shadow-fleet vessels that have transported oil and petroleum products from countries including Russia, Iran and Venezuela to help ease prices, a US official said on Wednesday.
该美国官员称，新的谈判重点在于美国可能允许此前受制裁的船舶运输“合法石油”。
