US president Donald Trump's administration has imposed sanctions on four oil tankers and their owners that it says were operating in Venezuela's oil sector, with the goal of escalating financial pressure on Venezuelan president Nicolas Maduro.
The newly designated vessels include the Della and Valiant, both 2mn bl-carrying very large crude carriers (VLCCs), the Rosalind, a 600,000 bl Panamax, and the 330,000 bl Nord Star. Vessel tracking shows the Della in the south Atlantic steaming toward Asia-Pacific and the Valiant in floating storage near Singapore.
Some of the tankers are part of the "shadow fleet" the US says have evaded sanctions, delivering financial resources to the Maduro government. The size of the shadow fleet, or tankers involved in legally dubious trades, has ballooned to around a fifth of the global tanker fleet to meet demand for transporting Russian, Iranian and Venezuelan cargoes.
"Today's action further signals that those involved in the Venezuelan oil trade continue to face significant sanctions risks," the US Treasury Department said.
Trump has been escalating pressure on the South American country. The US has imposed earlier rounds of sanctions on tankers and shipping companies, while seizing two tankers recently. On 16 December, Trump declared a "complete blockade" on most seaborne oil being shipped out of Venezuela, and earlier this week Trump claimed responsibility for a strike on a "dock area" he tied to alleged drug boats.
