We are entering a new Cold War between the US and China. Building on Donald Trump’s hostility, President Biden has ratcheted up tensions with America’s ‘strategic competitor’. He has openly declared “We are in a competition with China to win the 21st century” and he’s matched that with high-profile diplomatic stoushes, rising military spending and hawkish rhetoric around Taiwan. In Australia, the Liberal Government is openly speculating about the prospect of future war with China. This raises important questions for the socialist left. Is conflict with China likely? How do we oppose the growing imperialist tension, militarism and a future war?
