Senior officials from the U.S. and Russia meet in Saudi Arabia on improving ties and ending the war in Ukraine - but Ukraine isn't invited.

Saudi Arabia’s hosting of top American and Russian officials for a high-stakes rapprochement meeting underlines the kingdom’s aspirations to become a global actor capable of successfully mediating international conflicts.

Saudi Arabia's crown prince wasn't in the room for the first high-level talks between Russia and the United States over Moscow's war on Ukraine on Tuesday, but Mohammed bin Salman still won the day for hosting the gathering that could be a game-changer in the bloody conflict.
