This specific case is because of the (justified) increased oversight into Chinese IPOs in the US. Specifically, the issue was US regulators not being allowed to audit PRC operations of Chinese companies because to IPO, Chinese companies would create a parent org in the US that held a stake in the Chinese operations [0]. Because the SEC obviously didn't want companies potentially pulling an Enron, there was a crackdown on Chinese IPOs in the US in the 2019-2023 period, and these IPOs where overwhelmingly in the "tech" sector (which in reality is too broad a term. Even Luckin Coffee - a Chinese coffee brand - IPOed as a tech company).
Tit-for-tat retaliation like this is pretty normal to be honest, and this kind of title editorialization around US-China business news is honestly really stupid.
Hell, we in the US almost had a similar trade war with the EU because of the Inflation Reduction Act.
