I work in a typical office environment with many internationals because the company for which I work translates and transliterates academic articles. I recently trained several Chinese and Japanese employees one-on-one for a new project. Several weeks later, three of the female Asian trainees separately gave me small gifts. One employee gave me hand lotion and a bag of candy, another gave me an expensive candy bar and a third gave me Chinese candy and a purse from China for my wife. I am a young white American male and not in any sort of supervisory, managerial or leadership position, so there is no perceived incentive for brown-nosing. There was no indication that I like candy or that my wife needed a purse; all the gifts were unsolicited. I accepted all the gifts out of politeness, but I am curious to know if I am expected to reciprocate according to Chinese and Japanese cultures?
