The US hopes to warn the shipping industry that “no company is too big to fail” by putting two offshoots of China Cosco Shipping on the sanctions list, according to a senior official from the State Department.

On 25 September, Cosco Shipping Tanker (Dalian), Cosco Shipping Tanker (Dalian) Seaman & Ship Management, four other Chinese firms and five individuals became Washington’s Specially Designated Nationals (SDN) for allegedly transporting Iranian oil.
