<h1>U.S. Arranges Potential Russia-Ukraine Summit and Trilateral Follow-Up While Preconditions, Territory, and Security Guarantees Remain Unsettled</h1> The U.S. president announced he has initiated arrangements for a face-to-face meeting between the Russian and Ukrainian presidents to negotiate an end to the invasion, with a subsequent trilateral meeting including the U.S.; it remains unclear whether Russia has fully agreed. Key legal-political issues flagged include whether talks will require preconditions (ceasefire), negotiation over territorial status, the scope and form of proposed security guarantees described as 'NATO-like' without U.S. troop commitments, Russia's rejection of a NATO peacekeeping presence, and the prospect of reinforced sanctions or tariffs by the U.S. and Europe if Russia refuses direct negotiations.
