Venezuela's state-run oil company, PDVSA, sent a tanker in October to the Caribbean with the expectation that its cargo of crude would fetch about US$20 million - money the crisis-stricken nation desperately needs. Instead, the owner of the tanker, the Russian state-owned shipping conglomerate Sovcomflot, held the oil in hopes of collecting partial payment on US$30 million that it says PDVSA owes for unpaid shipping fees.
