In a meeting with Iranian President Hassan Rouhani, Amano called the JCPOA a good deal and reiterated that the Islamic Republic has been bound to all its commitments enshrined in the JCPOA.
The official pointed to the world support for Iran nuclear deal and said that all sides' commitment is vital to save the JCPOA.
He praised Iran's commitment to its obligations and declared its support for development of cooperation with Iran and presence of Iranian experts in the international organizations.
The IAEA chief arrived in Tehran late on Saturday to confer with top Iranian officials, including President Rouhani and Foreign Minister Mohammad Javad Zarif.
Analysts believe that Amano's day-long visit to Tehran is very important regarding the recent dispute began by US President Donald Trump over the July 2015 nuclear deal between Iran and the world powers.
Trump in his October 13 speech took a new strategy on Iran and decertified Iran's commitments to the international deal, the commitment to which has already been reaffirmed by the IAEA eight times.
