'Don't trust the West': Iran's supreme leader Ayatollah Ali Khamenei warns outgoing President Rouhani 'not to trust America' as the Islamic republic prepares for new administration to take power

• Khamenei said future generations should remember effects of US interference
• Rouhani signed a nuclear deal in 2015 but Trump backed out three years later
• The leader blasted the US for offering 'no help', branding them the 'enemy' 

Iran's supreme leader Ayatollah Ali Khamenei has said 'trusting the West does not work' after years of sanctions and thwarted deals with the US.

Khamenei told the outgoing President Hassan Rouhani's government that their experience of engaging with world powers such as the US has proved unhelpful after years of interference.  

Rouhani's signature diplomatic achievement, a 2015 nuclear deal with major powers, gave Iran some relief from international sanctions in exchange for limits on its nuclear programme.

But it was torpedoed in 2018 by then US president Donald Trump, who unilaterally withdrew from the agreement and reimposed punishing sanctions.

'Future generations should use this experience. It was made clear during this government that trusting the West does not work,' Khamenei told outgoing Rouhani and members of his cabinet.

Rouhani's government has been holding talks with major powers since April on bringing Washington back into the agreement, but a deal now seems unlikely until after he hands over to President-elect Ebrahim Raisi next month.

Khamenei said Washington has conditioned its return to the 2015 deal on including 'a sentence ... that (says) some issues be talked about in the future, or we will have no agreement'.

'With that sentence, they want to have an excuse for their next meddlings with the (deal) itself -- missiles and regional issues,' his official website quoted him as saying.

One of the major criticisms of the 2015 deal raised by Trump was its failure to address Iran's ballistic missile programme or its alleged interference in regional affairs.

But Tehran has always rejected bringing non-nuclear issues into the agreement, which is known formally as the Joint Comprehensive Plan of Action.

Khamenei also criticised the US for refusing to 'guarantee that (it) will not violate the agreement in the future' by pulling out unilaterally, as Trump did in 2018.

'Whenever you postponed issues with agreements with the West or negotiations with the West and America and the like, you were stuck and could not progress,' he told the Rouhani government.

'Because they don't help. They are the enemy after all.'

Trump's successor Joe Biden has signalled his readiness to return to the nuclear deal and has engaged in indirect negotiations with Iran alongside formal talks with the agreement's remaining parties, Britain, China, France, Germany and Russia.

Rouhani's successor Raisi is an ultra-conservative but has expressed support for the nuclear talks arguing that Iran needs an end to US sanctions.

Iran's ultraconservative camp, which deeply distrusts the United States, has repeatedly criticised Rouhani over the 2015 deal.

Raisi has said that his government will support talks that 'guarantee national interests', but will not allow negotiations for the sake of negotiations.
