In my experience most of the Chinese pilots are very respectful and friendly. Maybe some of the posters here just work for an airline with bad culture.
Also, most of the pilots I fly with prefer flying with foreigners because we treat them well and they feel they learn from us. I think my airline actually favors crewing the first officers based on their requests...if a first officer doesn't like foreigners he probably won't get paired with them as much.
I also find that in discussions of pay (which we are told to avoid) the first officers understand that we make great sacrifices to work in China and while we occupy the same cockpit, our jobs are in reality very different.
Still, if the roles were reversed, I suppose a lot of Americans or Europeans would be very upset if a bunch of Chinese came to their country and earned more money. But in the end it's not like we're taking their jobs from Chinese, these pilots advanced as fast as they can and don't even comprehend the thought that a slow economy could slow their career advancement. In their eyes, career advancement is only limited by their own ability to pass tests.
