During the meeting in Tehran on Sunday, Saiki said that his country has always encouraged continued negotiations between Iran and the Group 5+1 (the five permanent UN Security Council members plus Germany), and expressed the hope that the next rounds of talks would be constructive and fruitful and build the two sides' confidence in each other.
The last round of the talks between Tehran and the six world powers was held in Almaty, Kazakhstan, on February 26-27.
During the talks Iran and the world powers agreed to hold an experts meeting in Istanbul, Turkey, on March 17-18 and then continue their talks at the level of their top negotiators in Almaty on April 5-6.
Saiki also expressed pleasure in the positive and constructive talks he has had with Iranian officials during his visit to Tehran, specially with his counterpart Seyed Abbas Araqchi, and underlined Japan's eagerness to hold talks and develop cooperation with Iran in different arenas.
Diplomatic relations between Iran and Japan were formally established in 1926 and throughout history, the two countries have maintained a friendly and strongly cooperation in various arenas.
The two countries' officials have held talks in different economic, trade, political and cultural fields in recent years to explore new ways of expanding bilateral ties.
