In November, the Unites States granted a six-month waiver from sanctions to India and allowed New Delhi to continue to import a limited quantity of Iranian oil.
In the previous round of sanctions India did not halt oil imports from Iran, said Ansari, who is in India as part of a business delegation participating in a visit by Iran's foreign minister Javad Zarif.
The official said there is also a chance for Indian companies to get development rights for Iran's Farzad B gas field. Tehran could ease some terms associated with the project, he added.
