Iran's Supreme Leader Ayatollah Ali Khamenei this month banned the use of vaccines made by the United States and Britain, calling the jabs "completely untrustworthy".
Zarif confirmed that Iran had exceeded the relevant limit of 300 kg of uranium hexafluoride (UF6), but Foreign Ministry spokesman Abbas Mousavi said Iran's steps to decrease its commitments to the nuclear deal were 'reversible'.
"Our Indian friends have always been categorical in their intention to continue with economic cooperation and import of oil. I heard the same statement from my Indian counterpart," Zarif said, according to the ANI video.
"US now bans Iranian grandmothers from seeing their grandchildren, in a truly shameful exhibition of blind hostility to all Iranians," Zarif tweeted.
Resetting ties, India and Iran today held extensive talks on stepping up engagement on a range of key areas, particularly to increase Indian investment in oil and gas sectors in the Persian Gulf nation which has opened several lucrative sectors after lifting of sanctions under a landmark nuclear deal.
Prime Minister Narendra Modi is expected to hold a meeting this month to discuss with different ministries the proposed investment proposals worth Rs 2 lakh crore at crucial Chabahar port SEZ in Iran, Transport and Shipping Minister Nitin Gadkari said.
With the US and other western powers easing sanctions against Iran, India has been in talks with Tehran to set up a gas-based urea manufacturing plant at the Chabahar port, besides developing a gas discovery ONGC had made.
The Road Transport and Highways Minister was talking to media after chairing a high-level meeting on Chabahar port, attended by Railways Minister Suresh Prabhu, Petroleum Minister Dharmendra Pradhan, National Security Advisor Ajit Doval and Foreign Secretary S Jaishankar among others.
Under the deal, sanctions imposed by the United States, European Union and United Nations will be lifted in return for Iran agreeing long-term curbs on a nuclear programme that the West has suspected was aimed at creating a nuclear bomb.
Foreign ministers of US-led major world powers are racing to beat a midnight deadline to nail down a framework deal with Iran they hope will put an atomic bomb out of the Islamic republic's reach.
With the March 31 target fast approaching, the top diplomats from the five permanent members of the UN Security Council, Germany and Iran were meeting to try to bridge remaining gaps and hammer out the framework deal that would be the basis for a final accord to be reached by the end of June.
