Iranian Supreme Leader Ayatollah Ali Khamenei welcomed the nuclear deal between Iran and the world powers Sunday, a media report said.

The achievements, recognising the nuclear and enrichment rights of Iran by the powers, which could open the way for further economic and technical advancements, could be a “basis for Iranians’ vigilant measures in future”, reported Xinhua citing Iranian leader in response to a letter from President Hassan Rouhani.

Resistance against the “excessive demands” of some powers has been and will be the criteria for the Iranian officials, he added.

On Sunday, Mr. Rouhani congratulated Mr. Khamenei on nuclear deal between the Islamic republic and the P5+1 group, including the US, Britain, France, Russia and China plus Germany.

In the negotiations, Iran’s “nuclear rights and uranium enrichment were recognised”, the step which will bring about further achievements for the country, said Rouhani in his letter.

Iran and P5+1 reached a deal early Sunday after five days of intensive talks in Geneva.

The US and its allies will afford Iran with sanctions relief equivalent to $7 billion under the terms of the six-month nuclear deal, according to a White House statement. In exchange, Iran will halt nuclear enrichment above five percent in purity, it added.
