On Tuesday, the Trump administration imposed new sanctions on companies and individuals based in Iran and China over their alleged role in procuring missile “propellant ingredients” for Iran’s Islamic Revolutionary Guard Corps (IRGC).

“Iran’s aggressive development of missiles and other weapons capabilities imperils the safety of the United States and our partners,” Treasury Secretary Scott Bessent said in a statement on the sanctions.

The administration has maintained its so-called “maximum pressure campaign” against Tehran by adding new sanctions on Iran and threatening potential military action despite the negotiations it has held with Iranian officials.

Last week, the Iranian Foreign Ministry said the increasing US sanctions amid the effort at diplomacy shows a lack of goodwill.
