Of course. Iran is sanctioned by the United States, so we can't actually collect Iranian foreign exchange directly from domestic public accounts. Actually, there is a way to solve this problem. You can suggest that customers find friends in a third country or pay for their own money, so that our foreign exchange collection is equivalent to collecting foreign exchange from a third country, not Iran, and there is no problem. There is also the customer's own offshore account or others, as long as the payment is not Iranian, it is acceptable, so that the goods can be received and delivered normally.
