In the past one year and more since his election as Irani preisdent，Hassan Rouhani has been pushing gradual transition in domestic politics and dilopmacy in the middle-of-the road manner all the time. Under his leadership，the Irani economy ended the negative growth in 2014，going out of the edge of depression. The interation between Iran and the outside world has evidently strengthened，and there has occurred a detente in Irani and US relations. The Irani nuclear negotiations still move forward，the final comprehensive agreement has not been reached yet，and the negociations have not broken up and a postponement road map has been drawn up. Rouhani is short of charisma to redraw the Irani political configuration，reform on domestic politics and society lacking in strength. Iran hopes to continue consolidating its cooperation with the SCO. Soon after the SCO’s decision on membership expansion，Iran expressed its wish to join the organization.
