# Russia-Ukraine war: intensifying trilateral diplomacy > Live situation record from CLSTR: https://clstr.news/situations/st-petersburg-economic-forum-2026-amid-ukrainian-attacks > Updated: 2026-09-10T05:39:57.000Z. Sources: 430. Developments: 58. Diplomatic efforts to resolve the Russia-Ukraine conflict intensified in early September 2026 following shuttle missions to Moscow and Kyiv by American envoys Steve Witkoff and Jared Kushner. On September 5, the envoys met with President Vladimir Putin for approximately three hours. Following these meetings, U.S. Secretary of State Marco Rubio indicated that such contacts could lead to a formal plan for trilateral talks between Russia, Ukraine, and the United States in the coming weeks. On September 8, Donald Trump and Vladimir Putin held a one-hour telephone conversation to discuss ending the conflict. Russian Presidential Assistant Yury Ushakov described the call as ‘constructive and frank.’ During the discussion, Trump emphasized the desire for a swift resolution to facilitate the restoration of economic and trade relations between the U.S. and Russia. Putin provided a military analysis and expressed positive views regarding Trump’s mediation efforts, while assuring the U.S. president that Russia has no aggressive plans toward Europe. By September 9, Russia proposed Abu Dhabi, United Arab Emirates, as the venue for potential peace negotiations, an initiative discussed with the United States. While Secretary Rubio noted that recent discussions involved the exchange of ‘new ideas,’ Kremlin spokesperson Dmitry Peskov denied the existence of any fully formulated or coherent roadmap for ending the war. Despite the diplomatic push, challenges remain. Following a brief pause in hostilities during the envoys' visit, Russia resumed heavy missile and drone strikes on Kyiv, resulting in at least five civilian deaths. Ukrainian President Zelenskyy welcomed U.S. involvement and described certain proposals as ‘worthy of discussion,’ though he warned the conflict could persist until 2027. Meanwhile, Russian officials maintained that Moscow remains committed to achieving all its military objectives. ## Claims - Moscow has not received official requests for meetings with US negotiators Jared Kushner and Steve Witkoff.
