Rubio reports progress on post-war security for Ukraine and Europe

US Secretary of State Marco Rubio reported Sunday progress on defining the post-war "security architecture" for Ukraine and Europe, ahead of a G7 foreign ministers summit in Paris. Rubio spoke before flying to Paris, as US-mediated Russia-Ukraine negotiations are scheduled Tuesday and Wednesday in Abu Dhabi. He said security guarantees remain a recurring topic in discussions about ending the conflict, with a key question being the shape of post-war security arrangements for Ukraine and the broader European continent. President Donald Trump promised Thursday a "very big" agreement with Russia on Ukraine that "could encompass all of Europe," sparking concern among Europeans and Ukrainians about a deal made without them. Rubio stressed "nothing has been finalized" and progress may occur in Abu Dhabi, where US envoys Steve Witkoff and Jared Kushner are expected to represent Washington.
