US sanctions on Iran are a key component of Washington's foreign policy towards the Middle Eastern nation. These sanctions are a form of economic punishment imposed by the United States government on Iran in response to various issues, including Iran's nuclear program, human rights violations, and support for terrorism.
There are different types of US sanctions on Iran, including primary and secondary sanctions. Primary sanctions target US individuals and entities from engaging in certain transactions with Iran. Secondary sanctions, on the other hand, target non-US individuals and entities that conduct business with Iran, thereby restricting Iran's access to the global economy.
