Helpless...

The research project that I have been leading is decided to be extended until next February. The contract was signed yesterday. I will have to work at least until then...
A guy in our Swiss office who has been playing a significant role in the project has a difficulty in working with his colleagues. He is Indian. Other guys working with him are Austrian, French and their boss is Swiss; all westerners. He is Asian and has lived in Japan for a year or so. He understands well the feelings and practice of Japanese customers. However, others do not. They are simply logical and in a way always too reasonable. So the boss always supports the others but him. Their opinions have often clashed over the matters that are not logical. He has emailed me for advice.
He is now in quite a bit of distress. I would like to support him but it is hard. Eastern-Western difference is deep and wide. It is not something you understand through knowledge. It is deep seated on how you have grown up, in what environment, educational or cultural, you have lived. Internationalization is easy to say but hard to do.
I just feel helpless.
