A cargo of Iranian condensate intended for Venezuela, the fourth delivery this year, will discharge in coming days at the country's main oil port, a Venezuelan lawmaker said on Thursday.

Iran last year began providing the Venezuelan state-run oil company PDVSA with condensate that is used to make the South American nation's extra heavy oil exportable. This year, PDVSA and the National Iranian Oil Company (NIOC) signed a swap deal that formalized the exchange of Venezuelan crude for Iranian condensate.

The swaps, occurring amid US sanctions on both nations and their oil industries, have allowed PDVSA to ramp up crude output this autumn to levels close to those of early 2020.

"Two million barrels of diluent have just arrived. Where? - from Iran," said Angel Rodriguez, a lawmaker from President Nicolas Maduro's socialist party.

Washington imposed trade sanctions on PDVSA and its subsidiaries in 2019 as a way to oust Maduro after it called his re-election a sham. The measures barred exports to the United States, which used to buy most of Venezuela's crude.

PDVSA has adapted to the measures by finding new customers and ways to ship its crude and refined products to countries including China.

Iran has delivered some 4.8 million barrels of condensate to PDVSA and its joint ventures this year and has also supplied it with gasoline. It has received in return at least 5.8 million barrels of Venezuela's Merey 16 heavy crude and jet fuel.
