The Biden Administration has unveiled another round of blacklistings in a bid to punish companies that support Moscow’s war on Ukraine, slapping sanctions on a Russian shipowner, oilfield services firms and others.

The US State Department announced that it has designated Sakhalin Shipping Co (Sasco), along with two subsidiaries and a fleet of 14 vessels.

Officials said the company has provided key logistics support for multiple Russian energy projects by moving construction materials and equipment to the Taimyr Peninsula in the country’s far north.
