A top nuclear official warned that the nuclear deal with the West could be jeopardized over the sanctions issue.
Ali Akbar Salehi, the head of the Atomic Energy Organization of Iran, said the "durability" of the Joint Comprehensive Plan of Action, the formal name of the nuclear deal, depended on the other side's "reciprocal and full implementation".
Salehi declared that Tehran remains under some sanctions that were supposed to be removed following its landmark nuclear agreement with six world powers, AP reported.
He said Tehran is honoring all its commitments but that "comprehensive and expeditious removal of all sanctions" outlined in the agreement "have yet to be met".
Salehi did not blame specific countries in his comments on Monday to the International Atomic Energy Agency's general conference. But other Iranian officials have faulted the United States for foot-dragging in lifting financial sanctions.
The deal with the United States, Russia, China, Britain, France and Germany constrains the Iranian nuclear program in exchange for sanctions lifting. It went into force in January.
Iran complains that international financial sanctions are not being lifted quickly enough under the agreement that stipulates a removal of these and other penalties imposed over Tehran's nuclear program, in exchange for Tehran's agreement to curb its nuclear activities.
President Hassan Rouhani most recently sounded that theme last week at the UN General Assembly. While US financial institutions remain under tight restrictions as part of non-nuclear related sanctions, Rouhani said other banks complain about confusing signals from the US Treasury Department that create a "lot of doubt" about the legality of doing business with Tehran.
"As one thing, they [US Treasury] tell them 'you are free to engage with Iran in banking activity'," he said. "At other times, they ... enter the arena with threats."
Rouhani noted that they frighten the big banks.
