Al Jazeera: Mark Poffil, a former U.S. national security official, said Washington intends to avoid secondary sanctions on Chinese buyers of Iranian oil and keep this option available for essential circumstances. He noted that taking broad measures against Beijing is difficult due to the deep economic ties between the United States and China, so Washington is trying to encourage Chinese refineries to source oil from other origins. Poffil added that China benefits from Iran’s inexpensive crude oil and has no incentive to help Washington during Iran’s war.
