This is what is said under “Specific Sanctions”:

“The U.S. Treasury Department’s sanctions do not entirely cut off purchases of Venezuelan oil by U.S. refineries. However, they stipulate that refiners cannot make payments directly to PDVSA, but into escrow accounts that PDVSA will not get access to until the company is controlled by a new government.”

When it comes to business, all the so called ‘democratic’ countries go along with Ameicas’s ideas of wanting to control another country’s government. How is this democratic?
