Under the agreement reached in Geneva, Iran has committed to halt enrichment above five per cent, neutralize its stockpile of near-20 percent uranium and halt progress on its enrichment capacity, to halt progress on the growth of its 3.5 percent stockpile and committed to no further advances of its activities at Arak and to halt progress on its plutonium track.

In response, the US and five other major world powers have agreed to provide limited, temporary, targeted, and reversible relief while maintaining the vast bulk of the sanctions, including the oil, finance, and banking sanctions architecture.

"If Iran fails to meet its commitments, we will revoke the relief," the US fact sheet said.

"Sanctions affecting crude oil sales will continue to impose pressure on Iran's government. Working with our international partners, we have cut Iran's oil sales from 2.5 million barrels per day (bpd) in early 2012 to 1 million bpd today, denying Iran the ability to sell almost 1.5 million bpd," the fact sheet said.

"That's a loss of more than USD 80 billion since the beginning of 2012 that Iran will never be able to recoup.  Under this first step, the EU crude oil ban will remain in effect and Iran will be held to approximately 1 million bpd in sales, resulting in continuing lost sales worth an additional USD 4 billion per month, every month, going forward," it said.

India has slashed import of crude oil from Iran by over 26.5 percent in the financial year ended March 31 as US and European sanctions made it difficult to ship oil from the Persian Gulf nation.

India imported about 13.3 million tonnes of crude oil from Iran in 2012-13 fiscal, down from 18.1 million tones shipped in the previous financial year.

Oil sanctions alone will result in approximately USD 30 billion in lost revenues to Iran – or roughly USD 5 billion per month – compared to what Iran earned in a six month period in 2011, before these sanctions took effect.

Iran used to be India's second-largest supplier, but is now fifth or sixth.
