Chinese University admin asking for coauthorship on paper

I work at a Chinese university and have been put in a pretty uncomfortable situation.

The International Affairs Office of the university is in charge of all overseas staff and therefore the people who work there are pretty much my bosses, in addition to the department I work in. One of the senior admin in the International Affairs Office has requested that I put her name on one of my papers that I’ll be submitting this year.

The problem is, while she has suggested she could be involved in data gathering or analysis, I don’t know anything about this woman or her academic background. My previous interactions with her have not indicated that she has any experience in research. What she’s suggesting would seem to only rise to the level of research assistant but wants coauthorship. Moreover, just last year she justified cutting my salary by stating that my research “just isn’t that important to the university”.

I’ve been pressured in the past to our other people’s names on my research by senior members of the faculty where I work, but never by the administration.

How do I go about avoiding making this person lose face (over important in Chinese culture) while also rejecting her proposition?

Anyone with experience in Chinese higher education would be very welcome to this conversation!
