Iran has shown commitment to the deal on its nuclear program agreed with world powers, the head of the United Nations atomic energy watchdog said on Sunday.

"We are satisfied with the implementation of the (agreement) and hope that this process will continue," IAEA director general Yukiya Amano was quoted as telling reporters in Tehran by the IRNA news agency. 

"Iran has been committed to its engagement so far and this is important," Amano was quoted as saying after meeting Iran's nuclear energy chief, Ali Akbar Salehi.

Under the 2015 deal, Iran curbed its nuclear fuel production activities in exchange for relief from economic sanctions. 

Tehran is not allowed to enrich uranium above a 3.67 percent purity for 15 years, a level unlikely to be enough to run such vessels, according to experts.
