The United States is tightening its economic sanctions on Iran by ending a set of waivers Thursday that had allowed some of the country's largest oil buyers to continue their purchases.
With the expiration of waivers for eight buyers, U.S. Secretary of State Mike Pompeo says the United States would be exerting maximum pressure on the Iranian government.
The U.S. State Department called the move a fulfillment of the Trump administration's promise to get Iran's oil exports to zero and deny the regime the revenue it needs to fund terrorism and violent wars abroad.
The move is the latest in a series of steps the United States has taken since U.S. President Donald Trump took office with a pledge to withdraw from the international agreement that limited Iran's nuclear program in exchange for relief from economic sanctions.
Trump announced the withdrawal in May 2018, and new sanctions went into place in November, with oil purchase waivers in place for China, India, Japan, South Korea, Taiwan, Turkey, Italy and Greece.
Since then, Italy, Greece and Taiwan have halted their Iranian oil imports.
Turkey and China have attacked the U.S. action, but it is not clear whether they will continue to buy Iranian oil.
China, India workarounds
Samantha Gross, Foreign Policy Fellow at the Brookings Institution told VOA's Ira Mellman that most likely most parties will fall in line. Gross said one exception could be China, which may continue to buy some Iranian crude through the banks in China that are already under U.S. sanctions.
China and India are also trying to set up a trading bloc that would allow them to buy Iranian oil without going through the U.S. banking sector, Gross said.
This is a tricky thing for us, she said. Mechanism that move away from pricing oil in U.S. dollars is really not the best for us in the long run.
But, she said it appears that the Trump administration has decided that putting maximum pressure on Iran is more important than other foreign policy goals that might be affected by the move.
Iranian Oil Minister Bijan Zanganeh said Wednesday that the United States will not be able to bring Iranian oil exports to zero, and that Iran's oil-producing neighbors have exaggerated their ability to increase their production to a level that would replace the Iranian oil being blocked from the market.
Since announcing last month its intention to end the oil sanctions waivers, the Trump administration has expressed confidence that countries such as Saudi Arabia and the United Arab Emirates would offset any loss in Iranian oil.
