UN diplomacy week yields modest progress on Iran and Ukraine talks

The UN General Assembly week ended without breakthroughs on major conflicts, though talks on Iran and Ukraine inched forward and AI dominated discussions. Global powers used the venue to debate artificial intelligence risks with industry leaders. US and Iranian officials held first shuttle talks since July's ceasefire collapse, with Tehran reviewing Washington's response to proposals including lifting a naval blockade. Ukraine and Russia voiced interest in a limited ceasefire on grain and energy targets, though Moscow showed no commitment. Climate change was sidelined by AI concerns, with OpenAI and Anthropic CEOs urging government cooperation. Venezuela's interim President Delcy Rodriguez held first in-person talks with Trump, while Sudan's army chief was absent due to a US visa dispute. The UN faces an uncertain future as Secretary-General Guterres prepares to leave.
