The term arrogant, or arrogant powers, is used in Iran to refer to the US and its Western allies.
Talks between Iran and six powers are expected to fail to reach a deal to lift US and EU sanctions.
A senior Russian diplomat says if there’s a will in Washington & Tehran, a deal could be reached soon.
While all sides agree to keep talking, little progress has been made in overcoming significant disagreements.
The warning was issued at a board meeting of the UN’s International Atomic Energy Agency in Vienna.
The US last week penalised a number of Iranian and foreign companies for violating sanctions against Tehran.
