"Today, America is identified as an unreliable and untrustworthy country in the world which does not adhere to any of its obligations", Rouhani said.
His trip came on the same day that the USA restored sanctions on the Islamic Republic.
"We are in solidarity with the European Union position, obviously we are closely monitoring this and we are doing everything possible on the diplomatic level to stimulate a direct dialogue between the United States and Iran, and we think that dialogue should always prevail", he said.
Zarif went on to warn against Iran and the US being drawn into an escalated trade conflict. "They are imposing sanctions on Iranian children, patients and the nation", Iran's chief executive added.

European countries, hoping to persuade Tehran to continue to respect the nuclear deal, have promised to try to lessen the blow of sanctions and to urge their firms not to pull out. But that has proved hard: European companies have quit Iran, arguing that they can not risk their US business.
