What is the current state of US-Russia diplomatic relations regarding Ukraine?

Top US and Russian diplomats are meeting in Saudi Arabia for talks on resetting their fractured relations, marking the first such discussion since Russia's invasion of Ukraine. The UK Defense Minister emphasizes that a US backstop is essential for peace in Ukraine to prevent Vladimir Putin from attacking again. Simultaneously, the UK has declared its readiness to deploy troops to Ukraine to ensure security. These developments indicate both ongoing diplomatic efforts to address the conflict and Western powers' commitment to maintaining security measures to deter further Russian aggression.
