Araqchi left Tehran on Monday morning to visit Austria, Slovakia and Bulgaria.
He is going to hold political consultations with the officials of the three European states.
Apart from meetings with his counterparts, Araqchi is going to hold talks with the foreign ministers of the three EU members on various topics, including bilateral, regional and international issues.
The Iranian deputy minister is also scheduled to hold a meeting with Director-General of the International Atomic Energy Agency (IAEA) Yukiya Amano in Vienna for talks about the latest status of cooperation between Tehran and the UN nuclear agency within the framework of the 2015 nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA).
The nuclear agreement between Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany), was reached in July 2015 and came into force in January 2016.
Since the accord was signed in Vienna, the IAEA has repeatedly confirmed the Islamic Republic’s compliance with its commitments under the JCPOA.
