Gabriel's trip will be planned on a short notice as soon as there is a positive outcome of the talks, German government circles said.
The minister will reportedly be accompanied by a top business delegation, IRNA reported.
A leading German trade official recently expressed concern that his country could actually miss out Iran’s profitable market as other competitors are rushing to the Middle Eastern country to sign business agreements.
Responding to a recent IRNA question on the potential of the Iranian market for German firms during a meeting with members of the Berlin-based Foreign Press Association (VAP), the President of the Federation of German Industries (BDI) Ulrich Grillo said Iran could be “an interesting market once the sanctions are removed”.
German companies are especially enjoying a good reputation in Iran and hence can surely be active again in the Iranian market. However, German companies have to hurry once the sanctions are lifted because the competition does not sleep, Grillo warned.
German companies have actively pressed their government to boost efforts to promote trade relations with Iran as Western sanctions over Tehran's nuclear program are removed.
They lambasted Berlin's inaction in pushing ahead for closer trade ties with Iran as other Western companies were flocking to Tehran in the wake of the last year's Lausanne statement.
German exports to Iran surged 30 percent last year to reach 2.4 billion euros as a result of the partial lifting of Western sanctions.
Germany has been host to Iran trade conferences in recent weeks, culminating in the high-profile Berlin visit by Iranian Oil Minister Bijan Namdar Zanganeh in May.
