Speaking to reporters after the endorsement of the agreements on Wednesday, Erdogan underlined his country’s enthusiasm for starting a new chapter in the relations with Tehran, and said Turkey is in dire need of Iran’s energy resources.
"We import oil and natural gas from Iran and those are strategic products that Turkey imports from Iran and we can receive them more (than before),” Erdogan told reporters.
"Given the fact that Turkey’s industries are making progress on a daily basis and rapidly, we direly need energy products, specially Iran’s natural gas, and we should take joint win-win steps,” he added.
Erdogan also called for the further expansion of bilateral economic ties with Tehran, and said there is a political resolve in Iran and Turkey to increase the level of their trade exchanges to $30bln in 2015.
Iran and Turkey are both trying to return to the golden age of their relations after a period of recession of ties due to their differences on certain regional issues, specially in Syria.
The two Muslim neighboring states have increased their cooperation in various fields of economy, security, trade, education, energy and culture in recent years.
The two sides have exchanged several politico-economic delegations during the last few months.
