My engineering friend also said that he did not want to go back China after he knew the benefits working at a Chinese university. Chinese universities do not appreciate engineering degrees in USA much. Luckily, business schools in China are different. Some senior professors realize that it is necessary to introduce Western graduates to upgrade the research quality in China. So now we can see many names of professors working in China appear in top tier business journals.
I do not think getting work published in engineering top tier journals is easy. Actually, all top tier journals are difficult getting paper accepted. It is also easy for business professors to publish ten rubbish journal papers.
