"The current level of trade and customs ties between Iran and Germany is not favorable and we hope that positive steps can be taken to promote cooperation through talks with relevant authorities," IRNA quoted Olivier Yurtev, head of German Embassy's economy and commerce section as saying on Monday.
The German official made the comments in a meeting with Managing Director of Iran Customs International Cooperation Department Mojtaba Shishechiha.
The two sides discussed expansion of customs cooperation between Iran and Germany as well as trade ties.
Germany has traditionally been considered one of Iran's most important trade partners in the European Union.
Trade relations between the two countries have declined since 2012, when US-led sanctions against Iran over its nuclear program took effect.
However, despite the sweeping sanctions, Germany exported goods valued at $3.4 billion to Iran in 2012. Exports from Germany to Iran reached $1.8 billion between January and September 2013.
In April, Michael Tockuss, the president of German-Iran Chamber of Commerce announced that trade between Tehran and Berlin, which currently stands at €2.4 billion a year, could be doubled once the sanctions against Iran are removed.
In the meantime, German-Iranian Chamber of Industry and Commerce has estimated that Iran-Germany trade will reach €12 billion in the coming years.
