I'd be surprised if it works either with or without hyperref, as I'd  
expect the figure environment and/or the caption to reselect a  
Computer Modern font by default, or something like that.

Anyhow, for xelatex, don't use ad hoc \font declarations like that;  
use the fontspec package:

\documentclass{article}
\usepackage{hyperref}
\usepackage{fontspec}
\setmainfont{SimSun}
\begin{document}
\begin{figure}
\caption{中文 Chinese}
\end{figure}
\end{document}

See the documentation of fontspec for much more information (e.g., use  
\newfontfamily if you want to create a \chinesefont command that you  
can use for certain sections of the text, without changing the default  
font for the whole document).
