"Iran is looking for cooperation with Turkish companies in highway, airport and railway construction projects worth $10 billion in a period of three to five years," Bigdeli said.  
The Iranian ambassador said that Iran has many projects and is ready to grant them to the Turkish firms.
In May, Turkish Ambassador to Tehran Reza Hakan Tekin announced that a large number of his country's traders and capital holders have shown interest to invest in Iran.
"The Turkish firms are willing to invest in Iran," Hakan Tekin said in a meeting with Head of Isfahan Chamber of Commerce Seyed Abdolvahab Sahlabadi.
He noted that the conditions can be paved for the presence of Turkish investors in Iran due to the reasonable energy prices and the large number of Iranian experts.
The Turkish envoy said that his country has already invested over $2.1 billion in Iran.
Earlier this year, Iranian Ambassador to Ankara Alireza Bigdeli announced that the number of Turkish companies willing to invest in Iran has considerably increased in recent years.
"About 174 Turkish companies have already opened their branch offices in Iran," Bigdeli said.
The Iranian ambassador reiterated that the number of Turkish companies with representative offices in Iran is likely to rise to 300 in 2015.
"The Turkish businessmen and investors have become much interested to increase their presence in Iran," Bigdeli said.
He noted that the preferential trade agreement signed between Tehran and Ankara has positively influenced the two countries' trade and economic relations.
The two Muslim neighbors have been pursuing increasing widening of their ties in various fields in the last two decades. Iran is a main energy supplier to Turkey and Ankara has made huge investments in Iran.
Iran is a main destination of Turkish goods and Turkey is among the top destinations of Iranian tourists and traders.
The two states plan to multiply their trade transactions in the next few years.
