China, famous for never putting ideology over policy.

unless you're going back to the cultural revolution, modern China is extremely pragmatic. It's a nominally socialist country that runs deregulated special economic zones with tens of millions of people and more economic competition than anywhere else.

The equivalent would be if the US started to run a socialist planned city of 15 million people somewhere, just for the sake of it. There's pretty much no other place that in the last 30-40 years has as much of a spread of policy experimentation as China has had.
