Goods made under Socialism/Communism were and are of a much, much lower quality.
If you are old enough you might remember the imports from the Eastern Bloc?
Tools, cars, kitchen implements. Pure crap. The only decent products were guns. Shotguns, rifles, pistols. Plus the AK's of various models.
Do not forget China is still ruled by them, as is Vietnam. I am yet to see a product made there which is of a high standard.
Chinese factories make stuff according to specs, if given specs for quality products they are just as capable as anyone else.
As for "Goods made under Socialism/Communism", how about coughing up more nuance? Ukraine used to make all sorts of stuff, both quality and lesser quality just like in the west.
