Class struggle in China is not a primary contradiction for the world at this time. The more pressing issues to resolve are related to development of the global south and defeating imperialism's global neoliberal hegemony.

The tasks of a ruling communist party are different from those of one that is still engaged in revolutionary struggle. The CPC has a duty to its people to maintain peace and improve their lives in tangible ways. Socialism with Chinese Characteristics allows China to do these things in a way that no capitalist system ever could. If the CPC did not fulfil its duty to the people it would lose the mandate it has to rule.

How would it benefit the class struggle if the communist government of the largest economy on the planet fell because it prioritized dogmatic ideological goals over real material improvements to the people's lives?

Isn't the point of class struggle that by overthrowing the dictatorship of the bourgeoisie the lives of average people can finally improve and do so without the spoils of neo-colonialism and imperialism?

And China is waging class struggle, not just globally by uplifting the global south, but also domestically by taking action against the interests of capital, by dealing with issues like inequality, corruption and rural poverty.

This is what I am interested in hearing other people answer first. All I can say is that it is difficult for socialism to succeed in a capitalist dominated world. While I am also curious about the argument regarding class struggle, I believe each country's path to socialism will be different in different nations. China at this time is serving a massive role in maintaining peace as much as possible and to prevent another capitalist takeover of their country. This is necessary, especially with their 100 year plan and goal toward US dedollarization via becoming a world leading centralized nation mutually benefitting in trade with Eurasia and Africa. While people were hurt in the process, I believe the emancipation of the proletariat has an improved chance of succeeding across the world than if China had the same fate as the Soviet Union.

I suspect most people would have wanted the Cultural Revolution to succeed if it would have yielded better results, but that is not what happened. What is important is understanding the material reality and how it was impacted by Dengist policies, which brought China to its current stage today. Perhaps in the future we can see other countries have revolutions and manage to stick to the socialist only road, though I believe it is likely the case that China essentially took one for the team and allowed other countries to not have to go through the same struggles and risks.

They do talk about class struggle, it's part of the high school curriculum for the course “思想政治”, ideology and politics course. Also, you can look at the three represents, which tackles the class question.

There is a point where class struggle has to take the back seat in a socialist controlled country for you to properly levy your productive forces and create cohesion. Constantly fighting the forces within when bourgeois forces don't hold political power is self-defeating.
