Asymptote can output pdf and you should use this output with xelatex.
That's much better than eps. (The eps-output will due to the negative
coordinates never work properly with xelatex, and the compilation is
slower anyway). 

Btw: As far as I know the newest version of asymptote comes with a style
that has an option to force pdf-output and which works fine with xetex.
(But I don't know if chinese works too).
