Iranian oil exports to European countries had nearly stopped during sanctions.
After the implementation of the Joint Comprehensive Plan of Action (JCPOA) in January, the European countries resumed oil imports from Iran or began negotiations for imports of oil from the major oil producer.
Qamsari said that Iran's oil exports in October stood at 2.44 million barrels per day.
Asian countries continue to be the main destination for Iranian oil, according to Qamsari.
