An Al Jazeera commentary suggests that Russia could be an effective mediator in nuclear deal negotiations between the United States and Iran. The article posits that Russia's expertise in the nuclear field, increasingly close ties with Tehran, and negotiation experience give it a unique advantage. Russian Foreign Minister Lavrov visited Iran this week, meeting with Iranian President Pezeshkian and other officials, following previous meetings between Russian President Putin and Pezeshkian on October 8 and September 1. The article also mentions that U.S. President Donald Trump has stated that an unprecedented trilateral meeting with Putin and Chinese leader Xi Jinping at the Asia-Pacific Economic Cooperation (APEC) summit in Shenzhen next month would be meaningful if it could focus on denuclearization.
