"The volume of our (trade) exchanges (with other countries) would definitely rise after the lifting of sanctions," Nematzadeh said on the sidelines of a Wednesday cabinet meeting here in Tehran.
"Chemicals and petrochemicals, minerals like steel, copper, and precious metals, and auto industry are our priorities," he stressed.
Nematzadeh also announced that several cooperation agreements have been prepared and will be signed with other countries once sanctions are lifted.
The remarks came after Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany) on Tuesday concluded more than two weeks of intensive talks over Tehran's nuclear program in the Austrian capital of Vienna.
The negotiating parties reached a conclusion over the text of a comprehensive 159-page deal on the nuclear issue after 22 months of talks.
In a joint statement, EU High Representative Federica Mogherini, who has been coordinating diplomacy with Iran on behalf of the six powers, and Iranian Foreign Minister Javad Zarif, referred to Tuesday as "an historic day".
