Not many, I think. I usually look at the new section of HN and check what has been flagged unreasonably. Anti-chinese post are rarely flagged multiple times.
My opinion is that there are honest pro-chinese people on HN, most likely chinese working in the US who don't plan to stay for life and feel patriotic enough to protect the fatherland on internet forums.
