"So far there is only an understanding that the Russian position really is that this problem of Iran's nuclear dossier should be solved exclusively by peaceful political and diplomatic means," Kremlin spokesman Dmitry Peskov said.
"We believe that there is potential for this, because Iran is our ally, our partner, and a country with which we are developing comprehensive, mutually beneficial and mutually respectful relations, and Russia is ready to do everything possible for this. The United States is aware of this."
Trump last month restored his "maximum pressure" campaign on Iran which includes efforts to drive its oil exports down to zero in order to stop Tehran from obtaining a nuclear weapon. Iran denies any such intention.
