For example these days both regimes are preventing capital from exiting their country by banning any company that wishes to do so or if they insist the government bankrupts the hell out of them. China is doing it to its investment companies like those involved in real estate, US is doing it to a lot of companies including investment firms like BlackRock.
The difference is that China never claimed to be a "liberal economy or country" but US did
A couple of decades ago US economy was big and strong so they introduced strong laws against Child labor.
A couple of decades ago Chinese economy was tiny and weak so they introduced sweatshops with child (cheap) workers.
Today US economy is weakening and over the past couple of years the child labor laws in US are getting "looser" and American sweatshop are the expected reality as the violations are already up 300% according to the U.S. Department of Labor and that's the illegal cases, they are basically legalizing a lot of it so that they can get more minors (cheap labor) into their sweatshops and keep production alive for a little longer!
Well, it's obvious that China's grip on its companies is a world much tighter than the US'. I don't think the exodus of American brands would ever happen in China. Although there may be a somehow similar situation in the red country right now, this largely involves foreign companies. As to homegrown Chinese companies, I don't think its equally easy for them to leave the country as with homegrown US companies leaving the US. In the US, the capitalists are the ones holding the government at gunpoint. In China, it's the other way around. There's a huge difference as to where power actually resides.
When the US' tiger economy was in its infancy, child labor was rampant. Later on, standards improved as American people began living in abundance. China's story is more or less similar, although it started a bit later.
