How will the world trade regime handle a large, increasingly powerful country such as China that apparently plays globalisation by different rules? This is the question that keeps US and European policymakers awake at night. The fever runs highest in the US, where the Trump administration has blamed China for engaging in economic aggression and has declared trade war in response. The US president’s methods may be frowned upon, but the view that something has to be done about China’s trade and industrial practices is widespread among mainstream policy elites.

The tone is softer in Europe, but the concern is shared. EU trade commissioner Cecilia Malmstr?m , writing in the Financial Times, asks how we can reconcile China’s state-owned enterprises model with a global level playing field?

But US and European policymakers are asking the wrong question. The problem is not with China’s policies as much as it is with the world trading regime. The World Trade Organization — as well as every trade agreement since — has been predicated on the idea that economic practices in different nations would eventually converge. This has not happened, as China’s example amply indicates. More importantly, there is no good reason for national economic models to converge in the first place. World trade rules need to change, regardless of what China does, to accommodate economic diversity.
