Donald Trump is reported to be set to "decertify" the nuclear deal made with Iran in 2015.
The US President is believed to be attempting to impose wider and tougher restrictions on the government in Tehran, a move which could spark a potential backlash.
US officials told CNN Trump was moving forward with his decision despite the assessment by the international community, which said Iran was maintaining its condtions under the Joint Comprehensive Plan of Action (JCPOA) agreement.
The US President is not expected to completely rip up the plan, but to lay out a new strategy to counter flaws in the deal brokered by his predecessor, Barack Obama.
These plans are expected to highlight how the US can work with its allies to counter any threats made by the Iranians.
CNN reports an insider with knowledge of the strategy saying the world needed to look further than nuclear compliance terms in regard to Iran's behaviour.
