Washington has extended a waiver for companies to wind down their transactions with Cosco Shipping Tanker (Dalian), one of the main subsidiaries of state tanker giant Cosco Shipping Energy Transportation (CSET).

The lengthened reprieve will now last until 4 February 2020.

The waiver, which had been due to expire on Friday, would allow Cosco Dalian to continue its dealings with existing counterparties and banks to facilitate the associated transactions.
