Trump Imposes 50% Secondary Tariffs on Nations Supplying Iran with Weapons

Alongside the ceasefire announcement, President Trump declared 50% secondary tariffs on any nation supplying Iran with weapons, effective immediately with no exclusions or exemptions. The measure extends Trump's secondary tariff doctrine beyond trade into foreign-policy enforcement, aiming to deter Iran from rearming during and after the ceasefire period. It applies to all arms-supplying countries regardless of existing trade agreements, and analysts noted potential flashpoints with China and Russia — the principal suppliers of Iranian weapons systems.
