The United States has imposed extensive sanctions targeting over 100 individuals, companies, and vessels linked to Iran’s shipping industry, aiming to block Iranian oil exports. Central to these sanctions is Mohammad Hossein Shamkhani, who manages a complex network helping Iran and Russia sell oil globally. The move, part of increased pressure under President Trump, seeks to cut Iran’s revenue supporting its regime. Iran condemned the sanctions as hostile, while China remains its largest oil buyer. Diplomatic talks remain unlikely in the near future.
