Araqchi, who is in Vienna to attend talks with the EU on formula for the third Iran-G5+1 joint commission meeting, said the Iranian delegation had signed the deal with a US company on Friday.
Iran had been negotiating a commercial contract for three months, and finally the Iranian delegation signed a deal to sell as much as 32 tons of Iran’s excess heavy water supplies to a US company, he explained.
Araqchi added that some other countries have voiced interest in buying heavy water from Iran.
Iran is currently negotiating with some other parties for the export of heavy water, the deputy foreign minister noted.
Exporting heavy water supplies to the US is a major step for Iran, one which is expected to take the country toward the commercialization of its nuclear energy program.
