As per http://www.freedesktop.org/wiki/Software/LibreOffice/EasyHacks I cloned the writer module ( http://cgit.freedesktop.org/libreoffice/writer/ ) and made a patch removing all //CHINA-like comments (or some of them at least).
I hope to be more helpful in the comming future but this is my humble contribution to this new project.
