I have seen a little of the real market economy, I was a software developer in a consulting firm.
There are anti-dumping laws, but they are certainly ineffective.
China's "one family one child" program is a form of dumping. It allowed to reduce costs.
But dumping: it is temporary. In essence, you are losing resources. For example: China is no longer the biggest population country.
And there are anti-dumping strategies based on this. Your opponents allow you to dump, but do not allow you to get final preferences.
It is better to understand this from the beginning. I am not sure that Deng understood this.
From this point of view: the current economic storms are natural.
I do not know what will happen next. Maybe: China will return to classical Maoism. As a more realistic concept.
