Yes and west has their replication crisis which is massive fraud in all but name. PRC biases towards applied science so will get more applied science fraud. Ultimately countries with large R&D base strategy comes down to generating as much talent as possible and then spamming science at scale then seperating wheat from chaff via commercialization. First scientific community filters out what's valid - see PRC science+innovation climbing western rankings controlled for quality. Then market commercializes what works.

Sure, but does that mean if a reputable researcher at a reputable university (which do exist outside the US and Western Europe) provides strong evidence, should we discount all that simply because Chinese academia has a fraud and plagiarism problem?

Speaking of, I'd guess that the likes of Australian National University, Victoria University of Wellington, University of Tokyo and National University of Singapore (amongst others) would magically count as "American or Western European" for this test.
