The US has handed those waivers to eight countries: China, India, Greece, Taiwan, Italy, Japan, Turkey and South Korea.
"We have decided to issue temporary allotments to a handful of countries responsible to specific circumstances and to ensure a well-supplied oil market," Pompeo told reporters, stressing that the US would continue to be "relentless" in putting pressure on Iran.
"We continue negotiations to get all of the nations to zero [consumption of Iranian oil]," he added.
Marandi, a professor of English literature and orientalism at the University of Tehran, told Radio Sputnik's Loud & Clear on Tuesday that the political establishment within the US has yet to realize that it currently isn't as influential as it was in the past.
"The United States political establishment doesn't recognize that so much has changed over the past couple of decades, especially since September 11, 2001, and the United States no longer commands the sort of authority that it had before," Marandi told host Brian Becker.
"It has destroyed so many nations during this so-called war on terrorism, and also its involvement with the Saudis in Syria, Libya… Yemen."
"The view of the United States in this region is one of contempt… Iranians not only dislike [US President Donald] Trump and not only do they dislike his administration, [but] they are coming to dislike the United States because they see he is the elected president of the country," he added.
Turkish President Recep Tayyip Erdoğan recently slammed the US' latest round of reimposed sanctions on Iran's banking, energy and shipping industries, stating on Tuesday that they're aimed at "unbalancing the world."
"US sanctions on Iran are wrong," Erdoğan told reporters. "We don't want to live in an imperialist world."
"We've reached a stage where we no longer live in a unipolar mode. It is a multipolar world, although the United States is still the strongest of the major countries in the international community," Marandi said.
