Former German chancellor Gerhard Schroeder urged on Thursday direct talks between Iran and the United States.
Schroeder said that he would be "very happy" if such talks took place. He spoke on arrival in Teheran Thursday.
Schroeder was in the country to inaugurate a neuroscience center co-founded by a Germany-based Iranian specialist.
Schroeder denied he was carrying any message from Washington for Iran - which have had no diplomatic relations since 1979 - but said that he would discuss "political issues" with Iranian leaders. He also expressed hope the two will "choose new approach."
