(Kay Nietfeld/dpa via AP)2025-12-14T09:38:34Z BERLIN (AP) U.S. envoys arrived in Berlin Sunday morning for another round of talks intended to secure a deal to end the war in Ukraine.U.S. President Donald Trumps special envoy Steve Witkoff and Trumps son-in-law Jared Kushner were spotted in downtown Berlin by a photographer for German news agency dpa.Ukrainian President Volodymyr Zelenskyy said that Ukrainian, U.S. and European officials will hold a series of meetings in Berlin in the coming days.Most importantly, I will be meeting with envoys of President Trump, and there will also be meetings with our European partners, with many leaders, concerning the foundation of peace a political agreement to end the war, Zelenskyy said in an address to the nation late Saturday.Washington has tried for months to navigate the demands of each side as Trump presses for a swift end to Russias war and grows increasingly exasperated by delays. The search for possible compromises has run into major obstacles, including control of Ukraines eastern Donetsk region, which is mostly occupied by Russian forces, and security guarantees for Ukraine. The chance is considerable at this moment, and it matters for our every city, for our every Ukrainian community, Zelenskyy said. We are working to ensure that peace for Ukraine is dignified, and to secure a guarantee a guarantee, above all that Russia will not return to Ukraine for a third invasion. Tough obstacles remain Russian President Vladimir Putin has demanded that Ukraine withdraw its forces from the part of the Donetsk region still under its control and abandon its bid to join NATO among the key conditions for peace demands Kyiv has rejected.Putins foreign affairs adviser Yuri Ushakov told the business daily Kommersant that Russian police and national guard troops would stay in parts of eastern Ukraines Donbas even if they become a demilitarized zone under a prospective peace plan a demand likely to be rejected by Ukraine as U.S.-led negotiations drag on. Ushakov warned that a search for compromise could take a long time, noting that the U.S. proposals that took into account Russian demands had been worsened by alterations proposed by Ukraine and its European allies.Speaking to Russian state TV in remarks broadcast Sunday, Ushakov said that the contribution of Ukrainians and Europeans to these documents is unlikely to be constructive, warning that Moscow will have very strong objections.Ushakov added that the territorial issue was actively discussed in Moscow when Witkoff and Kushner met with Putin earlier this month. The Americans know and understand our position, he said.German Chancellor Friedrich Merz, who has spearheaded European efforts to support Ukraine alongside French President Emmanuel Macron and U.K. Prime Minister Keir Starmer, said Saturday that the decades of the Pax Americana are largely over for us in Europe and for us in Germany as well.He warned that Putins aim is a fundamental change to the borders in Europe, the restoration of the old Soviet Union within its borders. If Ukraine falls, he wont stop, Merz warned on Saturday during a party conference in Munich.Putin has denied plans to restore the Soviet Union or attack any European allies.

These days will be filled with diplomacy. Its very important that it brings results, Zelenskyy said.
