The Turkish minister of energy and natural resources suggested that his country and Iran found a joint chamber of commerce.
Taner Yildiz met Acting Foreign Minister Ali Akbar Salehi and held talks with him.
In their meeting Salehi said the two countries trade had reached $10 billion, but added that the desired goal was $30 billion.
He noted investment opportunities in Iran were many and pointed out that Iran's Turkish friends are aware of this fact.
The top official voiced Tehran's readiness to take part in joint venture with Ankara anywhere around the world.
Meanwhile, Iranian Oil Minister Masoud Mirkazemi and Turkish Energy and Natural Resources Minister Taner Yildiz also held a meeting in Tehran on Saturday.
During the meeting the two sides discussed issues of mutual interest.
Iranian gas transit to Europe via Turkey, boosting the two countries cooperation in the energy field, and Turkey's investment in Iranian gas fields were among the major topics of the meeting.
Currently Iran on average exports 30 million cubic meters of natural gas to Turkey per day.
Turkey agreed in 1996 to buy 10 billion cubic meters of natural gas annually for 25 years from Iran. Iran is Turkey's second largest supplier of natural gas after Russia. Turkey uses Iranian gas to fire half of its power plants.
Iran's gas exports to Turkey in 2009 amounted to roughly $7 billion, Press TV reported.
The gas network between the two countries has the capacity to increase the annual transfer of gas up to 15 billion cm.
The gas transfer through Bazargan border can be increased to even higher levels by developing the network in order to export more gas not only to Turkey, but also to other countries.
