The US showed hope that Iran will join diplomatic efforts after European countries did not criticise Tehran at the recent meeting of the International Atomic Energy Agency in Austria.

Iran has repeatedly said it will return to commitments in the nuclear deal signed with world powers in 2015 if the US removes sanctions on Tehran. US Secretary of State Antony Blinken said the US is willing to ease sanctions provided that Iran adheres to the commitments in the agreement.
