It's very easy to attack China's economic policy missteps of the past few years.
Propping up an overvalued stock market and surprising the market with currency announcements are just the latest examples.
But the bigger criticism is usually over the nature of the post-2009 stimulus package - which kept Chinese growth high by going on a credit and investment binge driven by state owned enterprises, state owned banks and local government.
That's left the Chinese economy with a serious mal-investment problem (the often mentioned empty ghost cities) and high level of debt. But, for all the criticism, the counterfactual is rarely stated. What would global growth have looked like without it?
At a time when the world was desperately short of economic demand, China stepped up and provided some.
That stimulus package helped prop up global growth during the crisis but left China's economy dangerously out of balance.
Helping China make the transition back towards balance needs to be a central aim for global policymakers.
