Russian President Vladimir Putin (R) meets with Saudi King Salman at the Kremlin in Moscow on Oct. 5, 2017. Saudi Arabia and Russia aren't on the friendliest of terms, but circumstances have aligned in such a way that each needs the other.
Saudi King Salman just made history as the first-ever Saudi king to visit Russia. Saudi Arabia and Russia aren't on the friendliest of terms, but circumstances have aligned in such a way that each needs the other. King Salman will spend four days in Moscow, meeting with high-ranking Russian officials, including President Vladimir Putin, mainly on energy and the economy. But the two sides will also try to find common ground on other more contentious issues, including Russia's involvement in Middle Eastern conflicts and Saudi Arabia's ties to Muslim regions in Russia. Saudi Arabia cut ties with the Soviet Union during the Cold War over divisions that have not completely mended. Moscow accuses Saudi Arabia of financing Muslim separatism in Russia in the 1990s, leading to two brutal wars in the Northern Caucasus. So it can hardly be blamed for worrying about Saudi Arabia's current ties to Russia's Muslim republics.
