This is especially true because the United States never really had much justification for withdrawing from the nuclear deal in the first place, beyond President Trump personally having problems with it. Pompeo's primary ammunition in the talks will be assurances that other nations, mostly Saudi Arabia, will replace Iran's oil exports on the market.
Listing the "privileges", he said that in the previous round of sanctions "Iran did its best to ensure security of oil supply to India and offered flexibility through selling oil with longer term credits and discounted prices as well as oil payments in rupee, and insurance coverage for oil shipments which facilitated our bilateral trade and pushed up significantly Indian export to Iran".
All told, producers and traders in the United States will send more than 15 million barrels of USA crude to India this year through July, compared with 8 million barrels in all of 2017.
Washington has threatened the countries potentially maintaining business with Iran despite the US's bans with "secondary sanctions".
In another tweet, Pompeo said that on Thursday, together with allies from Britain, France, Germany, Saudi Arabia and Jordan "we reaffirmed our support for the Syrian political process and our goals of removing Iran's influence, defeating #ISIS, deterring chemical weapons use". "We are looking for a mini-term deal to buy three to four cargoes of U.S. oil over a period of three to six months instead of buying single cargoes".
In May, President Donald Trump announced that the U.S. was withdrawing from the Iran nuclear deal signed by the Obama administration in 2015, under which Tehran had agreed to limit its sensitive nuclear activities and allow worldwide inspectors in return for lifting of crippling economic sanctions.
India, Iran's top oil client after China, has asked refiners to look for alternative oil supplies as the nation may have to drastically cut imports from Tehran to comply with the renewed United States sanctions.
Reuters' vessel tracking data show three of the eight tankers charted by Swiss and Chinese traders and sent to India in recent weeks were destined for a port near Reliance Industries Ltd's Jamnagar refinery, the world's largest.
Iran on Tuesday criticised India for not fulfilling its promise of making investments in expansion of the strategically located Chabahar port and said New Delhi will stand to lose "special privileges" if it cuts import of Iranian oil. Imports from other Middle East suppliers also increased.
US Secretary of State Mike Pompeo is reportedly set to meet with senior British, French and German officials on the sidelines of a North Atlantic Treaty Organisation summit in an attempt to persuade them to join Washington in pressuring Iran.
