In Vim, one character (even made up of several bytes) is one character.
You don't need anything to match the boundary of a CJK character, since
Vim cannot end (or start) a match in the middle of an ideogram. (If it
ever does, it's a bug, and it should be reported in the vim_dev group
with full details of how to make the bug appear in the latest version
and patchlevel of Vim.)

If you want to treat a space-separated sequence of CJK characters as a
unit, treat them as a WORD — and note that in Vim terminology, a word
and a WORD are not the same thing: see
:help word-motions
:help WORD
:help aW
:help iW
See also
:help /\<
which resends to
:help 'iskeyword'
and from there to
:help 'isfname'
which says that multibyte characters above 0xFF are always included in
these 'is…something' options.

If you want to treat as a unit a multisyllabic Chinese word (i.e. a
combination of successive hanzi which have no meaning in isolation but
only as a group), then AFAIK you're out of luck: Vim doesn't know the
Chinese language (nor does it know Japanese or Korean, for that matter)
and it cannot determine where such a non-space-separated multi-hanzi
word would start or end (except maybe if spell checking is on, but I
don't know the subtleties of CJK spell checking). The same applies of
course to non-space-separated kana or hangul, or indeed to any
non-space-separated mixture of kanji and kana, or of hanja and hangul.
