Due to post-Cold War geopolitics it was natural that Iran would find common cause with Moscow and even (as of the 2010's) Beijing. There's always been a hesitancy though on the part of Beijing to fully embrace Iran as it seemed like a potential conflict loomed with the United States – one Beijing didn't want to get dragged into. There are elements within the American political system that have been pushing for war with Iran since the 1979 revolution, a point Beijing knows all too well.
