Now, if one were following the events for the past two years, it'd be clear that Chinese government is responsible for all the above things. But they could've withheld from creating these conditions in the first place ( only that it'd take some adjusting and "kicking the can down the road"). Why did China create these conditions now ? - would be a good question to ask.
Covid Zero: Absolutely necessary. China is a Covid pandemic fight success, much to the chagrin of PRC's adversaries and critics. China keeps on adhering to this formula for the good of itself.
Property Jitters: China trying to avoid "Lehman crisis" or a serious burst. China chose 2021 as a good year to Tighten the screws and suffocate property moguls.
Power shortages: While australian ( and AUKUS, QUAD media) asserts that it is purely due to China banning Aussie coal and in turn scoring an own goal, other factors like Quota system that constricts Coal usage to meet its Green energy goals as well as the spike in industrial demand as the global economy tries to spring back from covid, are usually not highlighted.
Surging raw material prices: I don't know the details so i leave this.
