CLDR (Common Locale Data Repository) has RBNF (rule based number formatt)
data for various locales. For instance, take a look at
Chinese/Japanese/Korean  RBNF data at

http://www.unicode.org/repos/cldr/trunk/common/rbnf/zh.xml
http://www.unicode.org/repos/cldr/trunk/common/rbnf/zh_Hant.xml<http://www.unicode.org/repos/cldr/trunk/common/rbnf/zh.xml>
http://www.unicode.org/repos/cldr/trunk/common/rbnf/ja.xml<http://www.unicode.org/repos/cldr/trunk/common/rbnf/zh.xml>
http://www.unicode.org/repos/cldr/trunk/common/rbnf/ko.xml<http://www.unicode.org/repos/cldr/trunk/common/rbnf/zh.xml>

See the following two docs for the RBNF syntax :
