The meeting was the first time since Russia's full-scale invasion of Ukraine that Russian and American delegations are known to have met face-to-face.

Russia wants NATO to disavow its 2008 promise to one day give Ukraine membership of the U.S.-led military alliance, and for Ukraine to agree to neutrality, Foreign Ministry spokeswoman Maria Zakharova said on Tuesday.

The United States and Russia will appoint high-level teams to negotiate the end of the war in Ukraine and are working to reestablish diplomatic channels, US Secretary of State Marco Rubio said at the end of key talks that excluded Kyiv.
