US imports of Venezuelan crude oil are at zero barrels per day for three weeks in a row, according to the Energy Information Agency's weekly report for the week ending June 7.
By comparison, the report noted, during the same period last year, the US imported some 663,000 barrels per day from the Bolivarian Republic.
The absolute halt in imports is the third since January. In March, the US similarly halted all imports of Venezuelan oil for a three week period. In May, imports dropped to zero for two weeks.
Washington has also established a slush fund to fund the opposition using the seized wealth. Recently, Venezuelan President Nicolas Maduro accused the opposition of plundering oil profits which belong to the Venezuelan people.
The sanctions and de facto embargo have had a severe impact on Venezuela's oil output, and prompted Caracas to look for alternative markets and cooperation deals. Earlier this year, OPEC reported that Venezuelan oil output sunk from 1.4 million barrels per day before the US imposed restrictions in January to some 800,000 barrels per day in April.
Last week, Venezuelan oil minister Manuel Quevedo said PDVSA would open an office in Moscow later this month.
Venezuela has the largest proven oil reserves in the world, with 90 percent of the country's income estimated to depend on the oil industry. Over the past five months, Washington has attempted to squeeze the country's energy export earnings. In May, the US State Department reportedly contacted two trading houses in the UK and Switzerland, demanding that they stop trading Venezuelan-sourced jet fuel supplies or face sanctions.
Last month, the Energy Information Administration predicted that the decline in Venezuelan oil production would continue, and possibly accelerate.
Guiado proclaimed himself 'interim president' on January 23, and received near-immediate recognition from the US and its Latin American and European allies. Russia, China, Turkey, Iran and dozens of other countries have expressed their support for the Maduro government, or called on outside powers not to interfere in Venezuela's affairs.
