Eight governments including India were initially given six-month reprieves from the unilateral US sanctions on Iran.
The United States announced on Monday it will no longer grant sanctions exemptions to Iran's oil customers.
The White House said that Saudi Arabia and the United Arab Emirates - close US allies that back President Donald Trump's hawkish stance against regional rival Iran -- would work to make up the difference in oil to ensure that global markets are not rocked.
"This decision is intended to bring Iran's oil exports to zero, denying the regime its principal source of revenue," the White House said in a statement.
"The Trump administration and our allies are determined to sustain and expand the maximum economic pressure campaign against Iran to end the regime's destabilizing activity threatening the United States, our partners and allies and security in the Middle East," it said.
Saudi Arabia and others in OPEC will more than make up the Oil Flow difference in our now Full Sanctions on Iranian Oil. Iran is being given VERY BAD advice by @JohnKerry and people who helped him lead the U.S. into the very bad Iran Nuclear Deal. Big violation of Logan Act?— Donald J.

Eight governments were initially given six-month reprieves from the unilateral US sanctions on Iran. They include India, which has warm ties with Washington but disagrees on the US insistence that Iran is a threat.
Other countries that will be affected include China and Turkey, opening up new friction in contentious relationships if the United States goes ahead with sanctions over buying Iranian oil.
The others - Greece, Italy, Japan, South Korea and Taiwan - have already heavily reduced their purchases from Iran.
Trump last year withdrew the United States from an accord negotiated by his predecessor, Barack Obama, under which Iran drastically scaled back its nuclear program in return for promises of sanctions relief.
The Trump administration, backed by Saudi Arabia and Israel, has instead unilaterally imposed sanctions and demanded that other countries follow suit.
US officials say that they are aiming at choking off Iranian revenue so as to reduce the clerical regime's regional clout, notably its support for militants groups such as Lebanon's Hezbollah.
