Miyad Maleki, former head of the US Treasury Department's Sanctions Focus Office, said that Scott Besant's comments on the results of the campaign of economic pressure against the Islamic Republic in a conversation with Iran International show that the sanctions and the naval and air blockade had a significant impact. According to him, some foreign companies that previously cooperated with the Islamic Republic in the sale of oil and petrochemical products have stopped their activities. Malki added that the Islamic Republic still relies on cryptocurrencies and land routes to circumvent sanctions, but these methods are expensive and cannot replace sea and air trade. He emphasized that the US Treasury is monitoring cryptocurrency transactions and pressure on Iran's land trade routes is also increasing.
