This chapter reviews US-China-Russia relations in the post-war period, and considers how recent developments affect prospects for the US ‘pivot’. It explains why those driving US foreign policy towards China see the confrontation with Russia in Ukraine as a dangerous and diversionary adventure, leading to Sino-Russian convergence, distracting US attention from East Asia and undermining confidence among the US’s Asian allies of its commitment to the region. It is argued that if the US is to maintain primacy in the 21st century, it must subordinate other foreign policy goals to the paramount objective of containing China’s rise. The US’s failure to do this, instead pitting itself against both Putin in the West and China in the East, means it has driven Russia and China together, quite possibly sacrificing its vital need to contain China for a lesser goal of uncertain outcome in Ukraine.
