Geneva: Iran and three European powers are set to resume nuclear negotiations in Geneva on Tuesday, with discussions focused on Tehran's nuclear program and the lifting of sanctions.

According to Anadolu Agency, Iran's semi-official Tasnim news agency reported on Monday that the talks will involve Iran and the EU3 - the UK, France, and Germany. Iran's delegation will be led by Deputy Foreign Minister Majid Takht Ravanchi.

On Friday, Iranian Foreign Minister Abbas Araghchi engaged in phone conversations with his counterparts from the three European nations and the EU's foreign policy chief. Araghchi cautioned against any attempts to invoke the snapback mechanism under the 2015 nuclear agreement, describing such moves as 'legally baseless, morally unjustified and carrying serious consequences,' according to the news agency.

The UK, France, and Germany were part of the 2015 Joint Comprehensive Plan of Action (JCPOA) alongside the US, China, and Russia. The agreement imposed limits on Iran's uranium enrichment in return for the lifting of sanctions. However, the deal faced challenges when US President Donald Trump withdrew Washington, DC, from the accord in 2018 and reintroduced extensive sanctions.

The JCPOA includes a 'snapback' provision that allows signatories to reimpose UN sanctions on Iran if it is found to be in violation. Last month, the E3 and the EU also conducted nuclear discussions with Iran in Istanbul.
