Why on earth would the PRC or any communist country “abolish production relations”. History has shown that the most important task of any country that frees themselves from colonial oppression, is to build industry, and develop production to uplift their people out of poverty.

Ignoring this task and focusing on “abolishing the commodity form” is ultra-left/anarchist nonsense, trying to insert vague ideological statements instead of the objective material reality and tasks at hand. The PRC went through an entire historical period to learn from and reject this nonsense.

And the PRC is absolutely not capitalist: see here.

Get down to business, all of you! You will have capitalists beside you, including foreign capitalists, concessionaires and leaseholders. They will squeeze profits out of you amounting to hundreds per cent; they will enrich themselves, operating alongside of you. Let them. Meanwhile you will learn from them the business of running the economy, and only when you do that will you be able to build up a communist republic. Since we must necessarily learn quickly, any slackness in this respect is a serious crime. And we must undergo this training, this severe, stern and sometimes even cruel training, because we have no other way out.
