Well, evidently you have never published, or if you have, you have never run a larger (multi-pub) project. In this case, you'd publish and then proceed to do the background checks. If the background checks fail, you can publish those as well. If your original research turns out fine, you tack on some additional (original) research and publish that.
Also, given that it worked in a single case, you are evidently on to something. Ergo, checking again is, at this point, a waste of time. You share your findings with the world, and then have other people run with it as well.
More on-topic: I have seen a lot of Chinese, and more generally Asian, papers in my field... but not one of them is original. Also, doubtful results do pass by from time to time (although verifying this is hard, when it comes to sattelite observations there's no doing it twice). It seems that Chinese scholars (based on the ones I know and the research I see) are more concerned with quantity, as it improves your scholarly standing very directly, than with quality. So reproducing research (in my field: doing data assimilation on soil moisture for the umphteenth time) is a quick and easy way to get this.
The problem is exacerbated by american academic institutions, institutions are wholly dependent on getting major grants (or really the overhead money) and have publishing requirements for tenure track faculty. When it is as blatant as publish 25 (or similar) number of publications in 4 years, the rational thing to do is exactly this. Reproduce research / do application work to make sure that arbitrary number is cleared within the alloted time frame.
