The report put Iran-EU trade in the first five months of 2015 at €2.976 billion, showing a six-percent increase compared to the figure for the same period in 2014, according to the report, Tasnim News Agency reported.
The value of Iran-EU trade in the corresponding period last year stood at €2.81 billion, the Eurostat data showed.
Earlier last week, EU foreign policy chief Federica Mogherini paid an official visit to Tehran for talks with top Iranian officials on a range of issues, including economic ties between Iran and the European Union.
The visit came after Iran and the P5+1 (Russia, China, the US, Britain, France and Germany) concluded their intensive talks over Tehran's peaceful nuclear program in the Austrian capital of Vienna on July 14.
Experts believe that Iran's trade with the world would rise remarkably after the final nuclear deal takes effect.
