Some are mundane, some we don't notice, some we don't care about, some we misinterpret.
But 'cheating' is a problem in China which I have come to believe is factually true. Have a gander 
Also, thousands of Chinese ex-pat students have been expelled from US schools. 
For Singaporeans it's an unholy sin to cheat at exams, (you are barred from exams for the semester, all your grades for the entire semester are invalidated, you parents will be ashamed of you, and everyone you know will unfriend you) but copying homework/assignments/plagiarism is still somewhat tolerated before university level.
Very hard to draw any conclusions about this...
From the article: "About 8,000 Chinese students were expelled from American schools in the past year... Most were expelled because of a low grade point average (GPA)"
Another source quoting the same research says:
"A 54-page report released this week says that schools in the United States have expelled 1,657 Chinese since the 2012-2013 school year, mainly for “academic dishonesty or low academic performances,” but a company representative now says the number might be as high as 8,000 students. “A lot of students tend to keep silent or go back to their country,” says Andrew Chen, chief development officer at WholeRen."  (also, note that your source is wrong, as this is over the 3 year period from 2012 - 2015, not over the year 2015)
So it's 1657 over 3 years, but "might be as high as as high as 8000" according to a company representative? And over half of that was for poor performance, not cheating. So we can say that between 800 and 4000 students were expelled for academic dishonesty over 3 years.
How does that compare to the general population? Not sure, but according to these statistics, over 100,000 students were expelled in 2006 from public schools in the US.  They don't break this down by reason, but that's a pretty big number compared to 200 - 1300 in a year for Chinese students, especially considering the US hosts a quarter million Chinese students each year .
