"A sum of 10 cooperation pacts, mainly in economic areas, will be signed by the two countries' senior officials during President Rouhani's upcoming visit to Dushanbe," Sadri told FNA on Wednesday.
He noted that President Rouhani's upcoming visit will open a "new chapter in the two countries' bilateral ties".
Sadri pointed to the previous meetings between Iranian and Tajik presidents, and said, "President Rouhani and (Tajik President) Emomali Rahmon in their past two meetings exchanged views on the necessity for the expansion of cooperation and complete removal of obstacles and we hope that this visit will speed up the present positive trend."
The Iranian top diplomat also noted that the Iran-Tajikistan joint economic cooperation commission is due to hold a meting during President Rouhani's visit to Dushanbe.
"When the new government started its operation and began reassessing the quality of Iran's relations with the foreign countries, specially the regional countries, a clear landscape was envisaged in foreign diplomacy and friendship with the neighboring countries," he added.
President Rouhani will visit Tajikistan on September 12-13, 2014 to take part in the upcoming summit of the Shanghai Cooperation Organization (SCO).
