Iranian supreme leader Ayatollah Ali Khamenei said Iran will not be vulnerable to political or economic influences from the United States, as a result of the long sought for nuclear deal, if it passes.
Khamenei added that the deal could still be blocked by either country, according to a statement released on his personal website on Monday.
The deal is still waiting to be approved by the US Congress before taking effect. Khamenei has largely refrained from making any decisive statements over it, given that he is considered the most senior spiritual leader of the country.
Khamenei has cast aside his well known mistrust of the US and the world powers and encouraged the completion of the deal in July. Khamenei still refers to the US as "the great satan."
"They thought this deal - and it is not clear if it will be passed in Iran or in America - will open up Iran to their influence," Khamenei was quoted on his website as saying at a meeting with members of the Islamic Radio and Television Union.
"We blocked this path and will definitely block it in the future. We won't allow American political, economic or cultural influence in Iran."
International sanctions on Iran will be lifted if the deal is successfully passed. A market of nearly 80 million people will finally be open to foreign investment after years of isolation, since the 1979 Islamic revolution.
Khamenei has previously said that the deal’s fate is still largely unclear, and spoke about the US and said "in their understanding of the deal, of which its fate is not clear since it is not clear if will be approved here or there, their intention was to find a way to penetrate into the country."
