FNA - Head of the Iranian presidential office for political affairs Majid Takht Ravanchi underlined the need for implementation of the 2015 nuclear agreement between Tehran and the world powers, describing it as an internationally binding deal which should be respected under any US administration.

"We and other members of the Joint Comprehensive Plan of Action (JCPOA) expect the US to comply with its undertakings within the nuclear deal framework," Takht Ravanchi told the Persian-language Sharq newspaper on Saturday.

Asked if Iran will pursue implementation of the nuclear deal by Washington after the end of US President Donald Trump's tenure, he said, "Of course. Because it is an international demand and the US should implement it."

Takht Ravanchi, meantime, expressed doubt that Trump's successors would adopt a different foreign policy towards Iran, saying that the 2015 nuclear deal has special conditions which should be implemented under any administration.

Trump announced on May 8 that Washington would no longer remain part of the JCPOA and promised to re-impose the highest level of economic sanctions against Iran.

The sanctions reinstated on Iran on May 8 included boycott of Iran's crude supplies and bans on transfer of its crude revenues. Other US secondary sanctions were reinstated later.

After Trump's declaration, the Iranian government issued a statement, calling the US withdrawal as "unlawful". The statement underlined Iran's prerequisites for continuing the deal with the five world powers. These conditions that were reiterated later by Iran's Supreme Leader Ayatollah Seyed Ali Khamenei later mainly included Iran's guaranteed crude sales and transfer of its revenues back home.

Months later, the other five powers party to the nuclear deal have failed to satisfy Iran.
