Washington: U.S. President Donald Trump announced on Wednesday that all imports from countries supplying weapons to Iran will be immediately subjected to a 50 percent tariff without exception. This latest tariff threat comes just hours after the U.S. government reached a two-week ceasefire agreement with Iran.

According to Thai News Agency, following more than five weeks of continuous airstrikes on Iranian missile bases, military installations, and arms industries, the U.S. leader has once again resorted to his preferred foreign policy tool: tariffs. This move was communicated via social media to signal a warning to China and Russia, urging them to refrain from stockpiling weapons for the Iranian military.

President Trump declared on the Truth Social platform that any country supplying weapons and equipment to Iran will face a 50% tariff on all goods sold to the United States, effective immediately, with no exceptions or exemptions. However, the exercise of such power may encounter legal limitations.

In February, the U.S. Supreme Court restricted the president's use of the International Emergency Economic Powers Act (IEEPA), ruling that the broad global tariffs imposed under the 1977 law were unlawful. This decision effectively restricted the president's ability to quickly and comprehensively impose tariffs.

China and Russia are considered key allies aiding Iran in building its military capabilities to counter pressure from the United States and Israel. They reportedly provide support in terms of missiles, air defense systems, and dual-use technologies, suitable for both civilian and military applications. However, both China and Russia deny supplying weapons to Iran.
