"Given their unique capabilities and capacities, the Iranian and Turkmen markets complement each other, and there are many capacities in Turkmenistan's market for Iranian traders, industrialists and Iran's engineering-technical services," Salehi said on Thursday.
The Iranian foreign minister made the remarks in Turkmenistan's capital, Ashgabat, in an address to Iranian and Turkmen businessmen.
Salehi pointed out that the agreement signed by Iran, Turkmenistan, Uzbekistan, Oman and Qatar provides Iranian traders and private sector with many facilities.
In April, the foreign ministers of Iran, Turkmenistan, Uzbekistan, Qatar and Oman met in the Turkmen capital of Ashgabat to attend a meeting on international transportation and goods transit cooperation.
The five foreign ministers signed an agreement on transportation and the transit of goods via railway, sea and land.
The deal will help to connect the Persian Gulf and Central Asia as well as to facilitate the transit of goods between regional countries.
The Iranian foreign minister also stressed that the Islamic Republic should cooperate with Turkmenistan on advanced technologies including nanotechnology and producing and equipping laboratories.
"Last year trade volume between Iran and Turkmenistan amounted to USD 4 billion and we expect this figure to reach 5 billion this year," Salehi concluded.
During Salehi's trip to Ashgabat, the Iranian and Turkmen sides are due to sign a memorandum of understanding on mutual cooperation at the end of the meeting.
Earlier this week, Iranian Ambassador to Ashgabat Seyed Moussa Hashemi Golpayegani told FNA that during the trip, Salehi is scheduled to hold meetings with a number of senior Turkmen officials, including President Gurbanguly Berdimuhamedov and Foreign Minister Rashid Meredev.
Golpayegani expressed the hope that the visit would further promote expansion of bilateral ties between the two countries, and said, "We are happy that we are not faced with any problem in developing relations with Turkmenistan."
Iran has in recent years enhanced efforts to boost political, economic and cultural ties and cooperation with the regional and neighboring countries, specially those in the Central Asia.
