Yet slowbalisation has two big disadvantages. First, it creates new difficulties. In 1990-2010 most emerging countries were able to close some of the gap with developed ones. Now more will struggle to trade their way to riches. And there is a tension between a more regional trading pattern and a global financial system in which Wall Street and the Federal Reserve set the pulse for markets everywhere. Most countries’ interest rates will still be affected by America’s even as their trade patterns become less linked to it, leading to financial turbulence. The Fed is less likely to rescue foreigners by acting as a global lender of last resort, as it did a decade ago.

Second, slowbalisation will not fix the problems that globalisation created. Automation means there will be no renaissance of blue-collar jobs in the West. Firms will hire unskilled workers in the cheapest places in each region. Climate change, migration and tax-dodging will be even harder to solve without global co-operation. And far from moderating and containing China, slowbalisation will help it secure regional hegemony yet faster.
