I have a Chinese coworker -- fairly young. He's an awesome guy, we hit it off very quickly and ended up sharing a lot of interests. One of the things that we settled on early was that, if nothing else, the people of the world can agree on at least one thing: a dislike and distrust of politicians/elite leaders. He wasn't foaming-at-the-mouth angry or anything, but he also wasn't fawning. Fawning over China as a cultural entity, yes, but we were able to have a good number of fairly frank discussions.

Of course, there are still topics that felt totally taboo in such half-personal/half-professional relationships; Hong Kong was a sticking point that we avoided, for instance, and I never would have dreamed of bringing up Tiananmen.
