Global market. China itself is socialist (not as far along as the USSR’s fully planned economy, but even the USSR used a state-driven market economy for its first 20 years with Lenin’s NEP), i.e. the state uses the market for the good of the people, including when that goes against capitalists’ interests. You’re commenting on a post with an article talking about just that.
We’ve also been seeing this the last few months with how they’re tackling the real estate “crisis” by letting real estate developers go bankrupt and refusing to bail them out like capitalist countries do.
