In my experience, the ~30% of Chinese students who went to international schools, understood American culture very well, spoke almost perfect English, and who didn't exclusively hang out with other Chinese students never cheated any more than other students. It was the Chinese students who only hung out with other Chinese students who were the major cheaters However, I only ever TAed for undergraduate courses, where a much larger portion of Chinese students were from the subset with international educations / who were better able to culturally assimilate. And going to a school that was hard to get in to, typically you need to be very impressive to get in as a Chinese international student (or from a powerful family, preferably both) regardless. At a similarly selective program for graduate school, the Chinese students were, for lack of a better term, more "Chinese" culturally and more insular. I wouldn't be surprised if cheating were worse. But there's also the fact that graduate CS programs are less discerning of international applicants' credentials/pedigree
