My major question has been answered Citgo/Valero~no teeth, YET.
The decision also blocks Venezuela’s U.S. refiner Citgo Petroleum [PDVSAC.UL] from sending dividends back to the South American nation, a senior official said, in a further blow to PDVSA’s coffers.
However, the order stops short of a major ban on crude trading that could have disrupted the oil industry and plunged Venezuela into an even more severe economic crisis amid food shortages and rampant inflation.
It also protects holders of most existing Venezuelan government and PDVSA bonds, who were relieved the sanctions did not go further. Venezuelan and PDVSA bonds were trading broadly higher on Friday afternoon.
