E3/EU+3 reviewed Iran's nuclear commitments and agreed to continue work together to reassure economic operators about sanctions lifting," Schmid said in a message posted on her Twitter account on Friday after a joint commission meeting between Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) on Friday in the Austrian capital city of Vienna.
During the meeting, high-ranking diplomats from Iran and the Group 5+1 held talks on the process of implementation of the July 2015 nuclear deal between Tehran and the six world powers, known as the Joint Comprehensive Plan of Action (JCPOA).
Irans Deputy Foreign Minister for Legal and International Affairs Seyed Abbas Araqchi and EU's Schmid co-chaired the third meeting of the JCPOA Joint Commission.
The two sides discussed ways to resolve problems remaining after the start of the implementation of the agreement on January 16.
While the JCPOA came into force in January, some Iranian officials have complained about the US failure to fully implement the accord.
Last month, Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei said Americans have yet to fulfill what they were supposed to do as per the nuclear deal.
Iran still has problems in its banking transactions or in restoring its frozen assets, because Western countries and those involved in such processes are afraid of Americans, Imam Khamenei said, criticizing the US for its moves to prevent Iran from taking advantage of the sanctions removal.
