Unlikely, but most Chinese scientists would still publish their best research in English journals/conferences.
That's true of most scientists from non-English-speaking countries. By the by, there's a market for proofreading those translations (e.g. ThinkScience for the Japanese-to-English market). You won't learn Chinese, but if you're learning Chinese, it might be a good way to see how the Chinese make mistakes going back to English.
as one of the few native english speakers in my grad lab this was definitely a job of mine.
