As US and China limber up for strategic contest, which Asia battles will they pick to fight?
- A sharp increase in US-China rivalry has shifted the focus of geopolitical competition to Asia, where new proxy conflicts could now erupt
- The most likely locus of direct confrontation is in the South China Sea, says Michael Vatikiotis, though a Mekong River clash could be more worrying

Three decades have passed since the end of the nuclear-tipped Cold War between the US and Soviet Union. We tend to look back with relief that nuclear conflict was avoided. That did not mean the two powers avoided war. Starting in Korea in 1950, then in Indochina soon afterwards, more than 6 million people perished in wars in which the US and its allies battled forces backed by communist China and the Soviet Union.

A sharp increase in US-China rivalry has shifted the focus of geopolitical competition eastward to Asia, which begs the question: what are the chances of a war between the US and China? And if not between them directly, then which low-level conflicts in the region will these two great powers devise as proxy battlefields to avoid a costly head-on confrontation that would threaten their economies and have far higher political costs?
