Iran, China, and Russia have joined forces to contest the recent re-implementation of UN sanctions against Iran, initiated by the UK, France, and Germany through a ‘snapback’ mechanism from the 2015 nuclear deal (JCPOA). They argue this action lacks legal basis, as outlined in a letter to UN Secretary-General Antonio Guterres. The letter emphasizes that the three European nations have failed to meet their commitments under UN Resolution 2231, which expired on October 18, 2025. This geopolitical rift highlights changing global dynamics, with at least 120 countries supporting Iran, suggesting a shift in international perspectives on its nuclear program.
