The U.S. Treasury has reported progress in its efforts to isolate Iran through sanctions and diplomatic pressure, according to statements from Treasury official Scott Bessent. Bessent stated that teams had been dispatched globally to engage with countries to implement measures against the Iranian regime, and that these efforts "are bearing fruit." He cited the suspension of flights by the private Iranian airline Mahan Air by Turkey and Oman, as well as the cessation of all flights by Iranian airlines by the United Arab Emirates. Abu Dhabi had announced this measure to comply with new U.S. sanctions targeting the aviation sector. According to the Iranian news agency Isna, citing airport authorities, Iranian planes no longer have the right to land in Iraq, the United Arab Emirates, Oman, Azerbaijan, and Georgia. However, links continue to be maintained with China, which had rejected the "unilateral illegal" U.S. sanctions, and Russia, via the two main Iranian airlines Iran Air (national) and Mahan Air (private). In Turkey, although Mahan has suspended its flights, the link between the two countries continues to be maintained several times a day, in both directions, by Iran Air or smaller Iranian airlines, according to the websites of the airports in Tehran and Istanbul. According to Isna, Pakistan, Afghanistan, Armenia, Belarus, Tajikistan, and Malaysia continue to be served. Scott Bessent had assured on Monday that all Iranian airlines would be stopped "around the world" starting September 23. He also highlighted measures targeting Iranian banks. The UAE central bank has prohibited the branches of the public bank Melli from conducting any transactions with Iran, accusing them, among other things, of having violated laws against money laundering and financing of terrorism. The Turkish banking regulator has removed the license of the Mellat bank in the country, citing a provision of the banking law relating to the stability of the financial system. The deputy secretary of the Treasury responsible for countering terrorism financing, Jonathan Burke, conducted a two-week tour in the Middle East and Europe this month, and the U.S. Treasury has held discussions with more than 50 countries, according to the Wall Street Journal.
