This is the inside story of a revolution in China policy, from Washington to Brussels, Berlin to New Delhi. The Rupture explains how many of the Western politicians, thinkers and business leaders closest to Beijing have become its sharpest opponents; how the COVID-19 pandemic dramatically accelerated this collective rethink; and why 5G represents the first test case as to whether China may win the battle for the future. Noted China expert Andrew Small offers a kaleidoscopic picture of a rivalry ranging far beyond ‘great power’ politics. He traces US efforts to recast relations with old allies, as Washington realises that it cannot confront China alone, charting Europe’s growing role in the technological and economic contest, and Beijing’s attempts to build a coalition of its own, from Moscow to Taliban-run Kabul. As competition grows between systems, the Western model itself is transforming—for China’s rise changes the balance of ideas as much as the balance of power.
