European and Ukrainian officials met today in London for low-level talks regarding the ongoing war between Russia and Ukraine. However, today’s high-level negotiations between foreign ministers has been canceled, after both U.S. Secretary of State Marco Rubio and Special Envoy to the Middle East Steve Witkoff abruptly withdrew yesterday from the planned talks in London. Their withdrawal reportedly comes amid anger in Washington over Ukraine’s reluctance to agree to several controversial concessions to potentially end the war, including international recognition of Crimea as a territory of Russia and acknowledging Russia’s majority control over several other regions of Southeastern Ukraine.
