"During the talks, the world came to understand that respecting the Iranian nation would bear results, and sanctions would not work," Rouhani told reporters in a press briefing on Sunday.
He added the Iranian government is seeking confidence between Iran and the countries interested in establishing friendly ties with Iran.
Earlier on Sunday, Iran and the Group 5+1 (the five permanent UN Security Council members plus Germany) reached a final agreement, which includes recognition of Tehran’s right of uranium enrichment and removal and easing of the sanctions.
Iran and the Group signed a four-page agreement after five days of difficult and intensive negotiations and more than a decade-long nuclear standoff.
