Iran has increased its oil exports every year since Joe Biden's administration took office, and last year it exported an average of 1.55 million barrels of oil.
Shandong Ports Group, one of the largest oil terminals that receives oil from Iran, Russia and Venezuela, has banned the entry of oil tankers that have been sanctioned by the United States, in parallel with the significant decline in Iranian oil exports in the past two months.
Most of Iran's oil is transported to Chinese refineries through this port.
Iran also supplies another part of its oil to the ports of Dalian and Jawshan, to small and independent Chinese refineries, called Teapots, but its volume is much smaller than the oil unloaded in Shandong.
